Smoking doubles a person’s heart attack risk and triples their stroke risk.
Now, researchers from Herlev and Gentofte Hospital in Copenhagen, Denmark, have found evidence suggesting that smoking not only impacts a person’s blood vessels but also weakens the structure of the heart itself, impacting how well it functions.
The researchers recently presented their findings at the European Society of Cardiology (ESC) Congress 2022.
Past research shows that smoking negatively impacts a person’s blood vessels, potentially causing heart issues.
For example, the nicotine in cigarettes can cause blood vessels to narrow, limiting the amount of blood allowed to flow through them. Nicotine can also demonstrably increase a person’s blood pressure.
“We know that smoking causes coronary artery disease and heart failure,” explained Dr. Eva Holt of Herlev and Gentofte Hospital, Copenhagen, Denmark, lead author of this study.
“But the aim of this study was to investigate if smoking had an independent effect on cardiac structure and function in a large general population without known heart disease,” she specified.
Dr. Holt and her team evaluated data from over 3,800 participants of the fifth Copenhagen City Heart Study. This study examined cardiovascular diseases and risk factors in the general population. Study participants ranged in age from 20 to 93 years and did not have a history of heart disease.
Data collected during the study included a questionnaire addressing participants’ smoking history, as well as an echocardiogram or ultrasound of the heart.
Researchers determined that the current smokers in the participant pool had hearts that were thicker, heavier, and weaker compared to those who had never smoked. The study also found a correlation between increased cigarette “pack years” — 1 pack-year equals 20 cigarettes smoked every day for 1 year — and the heart’s decreased ability to pump blood.
“We found that current smoking and accumulated pack-years were associated with worsening of the structure and function of the left heart chamber — the most important part of the heart,” Dr. Holt says. “Furthermore, we found that over a 10-year period, those who continued smoking developed thicker, heavier and weaker hearts that were less able to pump blood compared to never smokers and those who quit during that time.”
MNT spoke with Dr. Rigved Tadwalkar, a board-certified cardiologist at Providence Saint John’s Health Center in Santa Monica, CA, who was not involved in this study.
“What’s interesting about this study is that it’s looking at changes in the main pumping chamber of the heart, the left ventricle, by tobacco use, which thus far has been less well explained,” he commented.
“We always talk about the link between tobacco use and disease of blood vessels, including arteries of the heart, but we haven’t really delved into the particulars of how it affects the structure and function of the heart itself,” he noted.
According to Dr. Tadwalkar, cigarettes increase the propensity for plaque development on the inside walls of the arteries, clinically known as atherosclerosis. This can lead to heart damage both directly and indirectly, he said.
“Directly, smoking damages the vascular wall, blood vessel wall, leading to constriction and reduced elasticity, as well as impaired function of the endothelial, which is the inner layer of the blood vessels,” he explained.
“Indirectly, there are multiple effects. Smoking can increase [the] inflammatory burden and this is demonstrated in a variety of ways, including increased platelet activity [and] increased homocysteine levels. It can increase thrombosis — which is the creation of clots — cholesterol levels, and it can lead to activation of the sympathetic nervous system, which is the part of the nervous system that’s responsible for increasing blood pressure and heart rate. So that chronic increase in blood pressure heart rate can lead to this dysfunction.”
– Dr. Rigved Tadwalkar
According to the new study, Dr. Holt and her team found evidence that quitting smoking can help the heart recuperate to some degree.
“The result that the heart seems to regain former structure and function after smoking cessation might be a valuable motivation to give the patient to stop smoking,” she added.
Dr. Tadwalkar agreed. “We certainly have data that it does and this study follows in a line of other prior studies that shows that in a variety of ways, and not just the heart alone, that quitting smoking will improve one’s health as a whole,” he explained.
“Immediately quitting smoking will lessen heart rate and blood pressure, as well as [the] sympathetic nervous system response,” Dr. Tadwalkar continued.
“So the good news is that even immediately, there are physiological benefits to this,” he pointed out. “And then the decrease over time in that inflammatory burden and these other destructive pathophysiologic processes, from a lack of chronic exposure, are part of the reasons for this improvement.”

Apart from drinking water, tea is the most extensively eaten consume throughout the world.
Tea consists of caffeine, which can be destructive in large quantities, so people are recommended to limit their consumption of tea and other caffeine-made up of beverages, these kinds of as coffee.
Having said that, tea is also higher in anti-oxidants, linked with a minimized chance of cardiovascular disease and cancer.
A massive-scale research has uncovered that those people who consume two or extra cups of black tea every day have a decreased mortality threat, even when taken with milk or sugar.
According to the United Nations, tea is the world’s most consumed drink, just after water. Of the many varieties, black tea is most prevalent in the United Kingdom and the United States. Environmentally friendly tea, jasmine tea, and fruit and herbal teas are far more well-known in other nations around the world.
Both black and environmentally friendly teas come from the Camellia sinensis plant. The change amongst them is how they are processed right after picking. Both of those are picked, wilted, bruised, and rolled before drying. Black tea is then oxidized by exposing it to the air for some time.
Scientists have very long examined the well being rewards of distinctive teas. Some counsel that green tea has larger wellness gains, whilst others advocate the wellness-offering qualities of black tea. Both way, antioxidants appear to be to be essential.
Now, a future cohort research of tea-ingesting patterns in just about fifty percent a million individuals from the U.K. Biobank has supported the added benefits of black tea.
This new analyze has located that consuming two or far more cups of black tea daily, with or without milk, may reduce mortality from all main results in of dying by up to 12{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}.
The study sample comprised 498,043 gentlemen and females ages 40 to 69. All contributors acquired actual physical examinations and furnished blood, urine, and saliva samples when they enrolled in the review from 2006 to 2010.
They then completed a baseline questionnaire about their tea ingesting routines. Contributors recorded how several cups of tea—on average—they drank each individual day and regardless of whether they drank their tea incredibly incredibly hot, scorching, or warm. They were then followed up for a median of 11.2 several years.
The researchers also recorded details on all participants’ food plan, lifestyle, overall health, ethnicity, and socioeconomic position. They altered mortality information to choose these elements into account.
Virtually 85{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of individuals claimed ingesting tea, with 89{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} ingesting black tea. Most of individuals who drank tea had amongst two and 5 cups for each day, with 19{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} consuming additional than 6 cups everyday.
Significant tea drinkers in the study were extra probable to be people who smoke, have poorer common wellbeing and eat far more pink and processed meat, which could boost mortality.
In the course of observe-up, 29,783 people died. Researchers observed that the chance of all-result in mortality decreased by about 12{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} as tea ingestion amplified to a few cups per working day.
People who drank a lot more than 3 cups of tea a working day did not have a decrease mortality danger than those people who drank in between one particular and three cups.
Including milk or sugar had minor effect on the observed added benefits of black tea. Likewise, the tea’s temperature was drunk and did not have an effect on mortality possibility.
“We observed the association irrespective of no matter whether folks took milk or sugar in their tea.”
– Dr. Maki Inoue-Choi, corresponding writer, Division of Cancer Epidemiology and Genetics, Nationwide Most cancers Institute.
Those people who drank far more than two cups of tea daily experienced a lower mortality risk from cardiovascular sickness, ischemic heart sickness, and stroke.
The scientists did not discover any affiliation among cancer and respiratory disease dying.
Tea is higher in polyphenols, which are anti-oxidants located in a lot of plant merchandise. Eco-friendly tea includes far more polyphenols than black tea.
Investigation indicates that a diet higher in polyphenols may well protect versus numerous health conditions, which includes significant blood stress, some cancers, cardiovascular disease, and variety 2 diabetic issues.
“Tea is extremely prosperous in bioactive compounds like polyphenols […] these have the opportunity to decrease oxidative worry […] that is the background system.”
– Dr. Inoue-Choi
Research has indicated that polyphenols in the diet plan have quite a few benefits, but abnormal quantities, these types of as may be found in supplements, could have adverse outcomes.
Black tea is made up of polyphenols known as theaflavins and thearubigins. Research have proven that theaflavins are highly effective anti-oxidants and could also have anti-inflammatory, anticancer, and antimicrobial homes, aiding to regulate blood lipids.
Dr. Inoue-Choi stated that black tea, “even at increased concentrations of consumption, can be aspect of a nutritious diet.”
Even so, the latest review uncovered no even more wellness positive aspects soon after the 3rd day-to-day cuppa. And tea has caffeine, which can have adverse effects at large consumption ranges.
Little amounts of caffeine have been demonstrated to enhance cognitive function and alertness and assist with fat reduction. More substantial amounts—more than 400mg per day—can cause challenges, this kind of as jitters and shakes, disrupted sleep, heartburn, and even large blood stress in some people.
Nonetheless, on common, three cups of tea have about 180mg of caffeine, so it must not lead to problems for everyone who is not caffeine-delicate.
The researchers admit that some variables were being not managed for in their research, such as the power of the tea, steeping time, or serving size. They also simply cannot prove that black tea was accountable for minimized mortality.
Dr. Inoue-Choi stated: “This analyze confirmed an affiliation […] but our findings will need to be replicated in other experiments […] and prolonged to other assorted populations as well.”
Dr. Inoue-Choi pressured the most significant information from their examine:
“Higher tea ingestion was involved with reduce risk of mortality, particularly in those ingesting much more than 2 cups a day. Even so, our findings do not point out that people need to commence consuming tea or modify their tea consumption to search for health rewards.”
Chimére L. Smith, 40, thought her bout with Covid in March 2020 would pass within two weeks, as most mild cases do. But the Baltimore English middle school teacher found herself continuously experiencing extreme fatigue, diarrhea, dry mouth, brain fog and a sore throat, which she initially attributed to a possible sinus infection. By April, she couldn’t work or drive, had lost 30 pounds, had spinal pain and lost complete vision in her left eye. She even thought about taking her own life. Smith was experiencing long Covid.
Smith said she visited hospitals a dozen times seeking help, but the physicians brushed her off, and one doctor labeled her “aggressive” when she insisted that severe headaches she experienced were due to Covid. She said she was repeatedly discharged with no resolution after each visit.
“I would come in with notes of my symptoms and share these symptoms with these doctors and they would not hear me. They wouldn’t listen to me. They would treat me as if I was a child and I didn’t know my body,” Smith said. “I wanted to die because I could not eat. I could hardly drink. I couldn’t think. Everything that I knew about my life within those first two or three months had been destroyed.”
That’s when Smith found the BIPOC Women Long Covid ‘Long Hauler’ Support Group, a Facebook group with hundreds of women of color with long Covid who meet virtually. Since joining the group in May 2021, Smith said she has been better equipped to advocate for her own care and that of Black women living with prolonged symptoms of the virus. She’s one of many Black people across the country suffering from long Covid who have found solace in communities of people having the same experience. Similar support groups have popped up in many states since the pandemic began, with Black people uniting to tackle everything from lingering symptoms to disparities in the nation’s health care system.

Long Covid — or post-Covid — was first identified in the U.S. in the months after the pandemic began in March 2020. And now, two and a half years into the public health crisis, a lot remains unknown about the prolonged illness that affects up to 23 million Americans. Symptoms of long Covid vary from person to person, with people reporting experiencing everything from fatigue and cognitive impairment to tissue damage and organ injury, according to the U.S. Government Accountability Office. Like most of the pandemic’s fallout, Black people are bearing the brunt of long Covid, with the group making up a majority of long Covid hospitalizations and researchers even projecting that Black people’s life expectancy will drop significantly in the next five years as a result. As a way to counter the troubling data, Black people have formed these support groups in hopes of making sense of the illness and to find the help they need.
“I am very proud to be a part of that group,” Smith said of the Facebook community. “As a matter of fact, that group is where I now spend a lot of my time because we become family, because we all share the same experiences.”
Margot Witvliet.Courtesy Margot Witvliet
Dr. Margot Gage Witvliet, a social epidemiologist and assistant professor at Lamar University, created the support group Smith is a part of in July 2020 after struggling with her own prolonged Covid symptoms. Witvliet, 40, contracted Covid in March 2020 and spoke about her experience in a TED Talk. She told NBC News that her husband and two children also contracted the virus, but her symptoms were the worst. She said in the TED Talk that she had trouble breathing and even suffered a seizure. Witvliet, who lost her grandmother to Covid, said she is just happy to be alive. Witvliet still endures chronic pain, fatigue and neurological issues, including short-term memory loss. Like Smith, Witvliet said doctors dismissed her symptoms and “infantilized” her. She said, on one occasion her glucose levels rose, which she believed to be a result of the virus, and a doctor told her to stop eating fried foods. In another incident, Witvliet was rushed to the hospital for a seizure, and was attended by a physician who asked if she had used drugs, she said. “I was not treated with dignity,” she said, adding that on one occasion her husband, who is white, accompanied her to an appointment. And the doctor would only address him. “Yet, I am the one who is a health expert with a PhD and I am not a child.”
After hearing multiple women of color share similar stories of seeking treatment for their long Covid symptoms, Witvliet decided to create a safe space where their voices could be heard.
“I wanted to be able to use the fact that I was a professor and a social epidemiologist to really help these women who were suffering,” Witvliet said. “So that’s what this group has done. And I’ve met some really phenomenal women, and we have lasting friendships in this group because we’re all unified by this trauma that’s happened to us.”
The Facebook support group has nearly 400 members, all women of color, and they discuss ways to monitor and alleviate their symptoms, and speak with doctors about long Covid diagnoses. Witvliet also invites experts to discuss self-care and health challenges related to Covid. As for Smith, who is an active member of the group, she said she helps members file paperwork to claim disability benefits because many group members are rejected. (As of July 2021, long Covid is considered a disability under the Americans with Disabilities Act.)
Barriers to long Covid care
Although there is no official test to diagnose long Covid, Dr. Sabrina Assoumou, an infectious diseases physician at Boston Medical Center, said that doctors look for symptoms like prolonged fatigue, cognitive dysfunction, shortness of breath and “lingering pulmonary symptoms” to determine whether a person is experiencing long Covid. She added that the same structural racism that makes Black people more susceptible to Covid than other groups are the same inequities that create barriers to receiving long Covid treatment. These barriers include, inadequate health insurance coverage, lack of access to long Covid resources and lack of primary care doctors.
Assoumou praised these long Covid support groups and provided advice for the communities as they navigate the illness and medical racism. She recommends that the group learn about the symptoms and long Covid definitions provided by the Centers for Disease Control and Prevention and be sure to document their experiences.
“Sometimes it can be overwhelming when you go see a doctor,” Assoumou said. “Take good notes and write down your symptoms over a certain period of time so when you’re in the office with the doctor you have your information ready and organized. Document your own history in your own words,” Assoumou said, adding that patients should prioritize long Covid clinics over general hospitals or urgent care centers.
“Inquire about these multidisciplinary clinics that help streamline things because they’re like one-stop shops where you get to see multiple specialists. It’s helpful for these groups to know these clinics exist and are available.”
Another leader helping the Black community navigate their long Covid symptoms is Yvonka Hall, executive director of the Northeast Ohio Black Health Coalition. Hall, 54, said some of her relatives contracted Covid and endured severe symptoms, like her uncle, who lost an arm as a result of blood clots, and her niece, who required emergency surgery due to a bowel obstruction. Hall contracted Covid in February 2020, before the vaccine was available in her predominately-Black Cleveland community, and said that she still struggles with brain fog, stomach issues and joint pain as a result of the virus.

In March 2021, Hall started a support group of about 10 members who continue to meet virtually for one hour each month. Hall’s group exists under the Northeast Ohio Black Health Coalition, a social justice organization Hall founded in 2011. Similar to Witvliet’s group, members can hear from experts who help them learn how to manage their symptoms and answer questions.
“When we get finished at the end, you can see some of the looks on people’s faces,” Hall said, “where it looks like a heavy burden has been lifted.”
Hall documented the group’s experiences with Covid in a documentary called “Black COVID, ‘The RONA.’” One member, Joncquil Hope, 38, of Campbell, Ohio, said she joined Hall’s support group earlier this year after contracting Covid in December. She said she suffered headaches, fatigue and brain fog, and still struggles with her memory. In the group, she’s able to openly discuss her symptoms while learning about new ones that may occur.
“It’s nice, because not only can we hear from people who may have experienced things similar to what I have, but it’s also nice to hear about people that are experiencing things that are different,” Hope said.

The fight for care and resources continues
Throughout the pandemic, the Northeast Ohio Black Health Coalition has provided some 60,000 masks to residents and 200,000 meals to disabled families. “We had families that were sharing masks because they didn’t have the money to get masks,” Hall said. The coalition also set up vaccination clinics where locals could learn about the long Covid support group, misinformation, and receive Covid vaccinations with a free meal. More than 170 people have been vaccinated at these clinics since Hall launched the effort in November 2021, and they plan to set up another clinic in October. Despite all the organization’s success, Hall said the community is still in need of supplies to protect against Covid and, ultimately, long Covid.
As for Witvliet, she said she’s focused on conducting research about long Covid in Black communities, and recently conducted a survey among more than 100 Black women with the prolonged illness. She asked the women about navigating the illness and their experiences with doctors. Witvliet said the research will help Black women deal with the symptoms of long Covid and she hopes her efforts will prompt the medical community to reconsider how they interact with patients of color.
Black-led Covid support groups provide solace for long haulers
Witvliet said Covid researchers may not understand the particular struggles of women of color. “We’re not honing in enough on how the social determinants of health are going to impact the recovery process — and that’s going to look different in different subgroups. And I think that that’s like an elephant in the room that’s not being discussed,” she said.
Meanwhile, advocates like Smith are calling on the government to address health care disparities. In April 2021, Smith testified about her illness at a congressional hearing, delivering a speech in front of Reps. Anna Eshoo, D-Calif., and Ayanna Pressley, D-Mass., both of whom said they had a lot of compassion for her, Smith recalled. Smith said she wants to help push the “TREAT Long Covid Act,” a bill that requires the Department of Health and Human Services to award grants to create and expand long Covid recovery facilities.
“Many of us have lost our health care because of long Covid and because we don’t work anymore,” Smith said. “We need quicker turnaround times for social security decisions and actual acknowledgement from our federal government — that long Covid is a condition and it’s a medical diagnosis.”
While dealing with long Covid has been an ongoing challenge for Smith, she said there’s also been some bright spots. Smith said she has grown closer to her family and others dealing with long Covid through the support group. She also received a lot of financial support from people online through Facebook, CashApp and other digital payment apps after sharing a video asking for help when her bank account went down to $10 in 2020. Smith, who can no longer work and receives disability benefits, said former co-workers and students reach out to her to express how much they miss her.
Meanwhile, Witvliet said the steady improvement of her symptoms has helped give her hope.
“I am not in the same situation that I was at six months, 10 months or 12 months or 18 months,” Witvliet said, “and that’s what people need to know. You will get better. You have to believe it.”
In a bid to curb the spread of SARS-CoV-2, the virus that causes COVID-19, public health experts have been pushing for a fast and effective vaccine rollout. However, some members of the public have been hesitant to take up vaccines. What happened, and is there something that science communicators keep getting wrong about vaccine hesitancy?
Millions of people around the world have now received a vaccine for COVID-19, yet for many the decision was not an easy one — indeed, some people are yet to accept a COVID-19 vaccine, even though it is available to them.
Some researchers have named this phenomenon “vaccine hesitancy” — the European Centre for Disease Prevention and Control (ECDC) defines it as the “delay in acceptance or refusal of vaccines despite availability of vaccination services.”
But what renders people unsure about accepting any given vaccine? And is vaccine hesitancy something that science communicators can help resolve?
Theories about the reasons behind people’s vaccine-related worries abound, and they may all hold some truth. Some researchers surmise that what makes people hesitant about whether or not they should accept a vaccine is the lack of access to accurate, complete information about that vaccine.
Others say that it all comes down to the spread of willful dis- and misinformation about vaccination. Yet others point out that, during the COVID-19 pandemic, those belonging to some historically marginalized communities, such as Black Americans, were the most likely to be hesitant about COVID-19 vaccines.
This is due to a long history of medical experimentation and gaslighting experienced by this community, as well as to present experiences of racism and discrimination when attempting to access healthcare.
But the lack of trust in scientists and public health authorities spreads much farther and deeper, and it may be a core factor in vaccine hesitancy around the world.
We were also joined by reporter Aaron Khemchandani, who is a science communication MSc student at Imperial College London in the United Kingdom, and who has studied the phenomenon of mistrust in science.
This feature is based on an edited and shortened record of the discussion featured in our podcast. You can listen to the podcast in full below or on your preferred platform.
In her book, Prof. Goldenberg explains that vaccine hesitancy is a spectrum phenomenon — people may feel anywhere from vaguely uncertain about whether or not a vaccine is safe and effective, to very anxious about its potential effects.
Yet the concept itself, she explains, is a fairly new one for public health experts to focus on — historically, public health institutions have focused on recording rates of vaccine refusal rather than looking at what makes people hesitant about accepting vaccines, regardless of their final decision.
Understanding what drives vaccine hesitancy, however, is far more helpful when it comes to promoting public health, Prof. Goldenberg argues. Firstly, she writes, understanding people’s misgivings about vaccines and allaying those fears can help boost vaccine uptake.
Secondly, failing to effectively communicate with people about what makes them hesitant when it comes to vaccination can actually make up their minds to refuse it.
So what are the factors that drive vaccine hesitancy? The COVID-19 pandemic has made one of them clear: Many people around the world do not trust national and international health authorities, often for complex reasons.
In our latest podcast episode, Aaron Khemchandani gave the situation in Hong Kong as an example, explaining that the mistrust in governmental institutions initially led to low COVID-19 vaccine uptake. However, the ensuing rise in COVID-19 cases eventually flipped the script, Aaron noted.
“[P]eople decided that the vaccine was important to protect the community, and community is one of the values that, especially in East Asia, is widely prioritized among the population. From the start of the pandemic, [in] Hong Kong mask wearing was widespread, because masks […] protect other people from you, so people wanted to protect their loved ones,” he explained.
“[T]hat just showed how [much] Hong Kong valued protecting the wider society, and so vaccines became part of that when [COVID-19] case numbers started to rise,” Aaron added.
While the outcome here is a positive one, for Prof. Goldenberg, the initial resistance to vaccines in Hong Kong was very telling about the way in which people’s relationship with institutions can influence their views about, and trust in, medical interventions.
“The things that really stand out to me from this account from Hong Kong,” she told us,” is the way that general trust in government and social structures influence opinions about vaccines.”
“[T]his goes against the common thinking that people who don’t vaccinate somehow don’t understand the science, or have some kind of cognitive break that keeps them from doing the right thing. Instead, there’s lots of social science research, not just in Hong Kong, but in many countries, pre-COVID and during COVID, showing that a person’s trust in government, especially [in a] government dealing with a crisis is largely correlated with your likelihood to get vaccinated. […] You have to trust the system that brings you vaccines, in order to be willing to participate in [vaccination programmes].”
– Prof. Maya Goldenberg
“It’s not about understanding science, […] it’s about trusting the scientific and regulatory process that is bringing us vaccines and telling us that [they are] safe and effective, and something that we should [accept]. If you don’t trust the system, you’re not going to trust the vaccine,” she pointed out.
While it may be helpful to think about hesitancy rather than refusal when it comes to understanding the factors that influence vaccine uptake, not everybody agrees that the term “vaccine hesitancy” is a useful one in every context.
For some, it is a misnomer that fails to acknowledge the fact that medical institutions themselves are sometimes to blame for the low uptake of vaccines in the community.
“[T]here were serious political complaints about the use of the term when, let’s say, there wasn’t enough access [to] vaccines [among] marginalized groups,” Prof. Goldenberg told us.
“And politicians would say, ‘well, they’re just vaccine-hesitant.’ And people from within those communities would say, ‘well, that’s [a] lazy use of the term, we have an access problem, we don’t have a vaccine hesitancy problem, and they’re using [the term] as a slide for not taking responsibility, for the lack of infrastructure, for the lack of supports for people who are not fully integrated into the system’,” she explained.
In fact, in the United States and elsewhere in Western countries, the people who have been disproportionately affected by COVID-19 throughout the pandemic are those belonging to historically marginalized communities, such as migrants, Black and Hispanic individuals, and those with undocumented status.
Oftentimes, individuals belonging to these communities work in customer-facing roles that increase their risk of infection, may face less safe living conditions such as overcrowded housing, and may have limited or no access to timely healthcare.
Even when they do have access to vaccines, people belonging to marginalized groups may still be hesitant to take them. Why is that?
According to research looking at vaccine hesitancy among Black adults in the U.S., their views on vaccination are “tied to the long legacy of systemic racism in the U.S. healthcare system.”
Both historical and recent personal experiences of discrimination in healthcare have rendered many Black adults less likely to trust the health system and healthcare providers who do not understand their needs and may often perpetuate harmful stereotypes.
“I think [the experience of current and historic discrimination is] a major driver of vaccine hesitancy,” Prof. Goldenberg told us. “I think it was like that before COVID, but it somehow became more visible to the public [during the pandemic.”
“I remember near the beginning of [the] COVID [pandemic], they had done a lot of survey research, when the COVID vaccines become available, [asking] ‘will you get vaccinated?’,” she recalled, “and it was treated as a surprise that marginalized groups who were suffering the most from COVID, [the] people that couldn’t work from home, lived in housing conditions that [weren’t] conducive to social distancing, […] were the least likely to get vaccinated.”
“And it shouldn’t have been treated as a shock, because I think the knowledge about mistrust of healthcare and government among marginalized communities was already there. It’s just that the links hadn’t been made between healthcare decision-making and experiences of marginalization. Truth is, we don’t even need to look that far back to famous case studies, like the Tuskegee syphilis studies — you can look at the experiences of […] people in healthcare today to understand why they’re not front in line there […]”
– Prof. Maya Goldenberg
It is difficult to deny that vaccine hesitancy is also complicated by wilful mis- and disinformation spread by influencers with questionable agendas.
In our discussion, Aaron mentioned the disproportionate impact of the so-called Disinformation Dozen — in 2021, the Center for Countering Digital Hate (CCDH) published the results of an investigation that found that most of the disinformation spread about COVID-19 vaccines online at that time had originated from no more than 12 active social influencers.
In today’s fast-paced digital age, altered information can spread very fast and do much harm. However, while she acknowledged the impact of mis- and disinformation, Prof. Goldenberg cautioned that we must be wary of blaming lack of trust in vaccines exclusively on the wrong information that easily circulates online.
There will always be bad social actors who spread health myths, she noted, and simply debunking those myths over and over will not be enough to restore the trust in health institutions, she argued.
Prof. Goldenberg also thought that some people may be attracted to these bad actors precisely because they place themselves in the role of fighters against an oppressive system — and that is what we need to address.
“[T]hat, for some reason, resonates with a lot of people and people who have experience of [how] this system fails them — the American dream is not something that they feel is within reach for them. So we need to look at the sort of social structures that create this level of dissatisfaction,” she emphasized.
“I look at all the time spent debunking the myths being propagated by these disinformants, and it’s almost beside the point. It’s not that we should let this disinformation linger […] But the point is, it’s just going to move from one [source] to another, you shut down one source another one will open up because there’s an appetite for it. You debunk one myth, it’s OK, another one will pop up in its place because people are looking for that kind of outlet. […] [W]hatever hurts that they are feeling they want to place it on something, and placing it on these kinds of disinformation and conspiracy theories [is] a way to have it all make sense […]”
– Prof. Maya Goldenberg
So if a lack of trust between the public and health experts and organizations is the core driver for vaccine hesitancy, how can we repair that trust?
Recent research suggests that what is most important for scientists, organizations, and individuals is to communicate with empathy, above all.
“There’s been good research demonstrating that the way to talk to people about vaccines is, first of all, not to try to convince them otherwise, and not to ply them with the facts,” said Prof. Goldenberg.
“A sympathetic approach is what works, you have to hear them out, listen to what they have to say, try not to be judgmental about it — that is hard to do sometimes because we’re all kind of tired and would like things to go a little easier. But the best thing to do is listen to what they have to say, respond not with the fact-based approach […] but [instead] ask more questions and try to find out where the source of the misgivings [lies]. There might be concrete pieces of misinformation, perhaps you can deal with that. But it needs to be done in a respectful way, the same way you would want to be spoken to by someone who disagrees with you.”

“It’s more about try[ing] to meet them on common ground,” she noted.
Vaccine mandates may push some people to get vaccinated in the short term, but in the long term they will do little to report the trust between the public, the government, and health organizations, Aaron also pointed out.
“[Goverment-mandated restrictions] did increase the vaccine rate, but didn’t do anything to repair the trust between citizens and the government, because it was sort of done out of necessity and fear, as opposed to sharing any sort of values with government officials and their plan for success in [the COVID-19 pandemic],” he explained.
Aaron was in agreement with Prof. Goldenberg that empathy is key, and science communicators need to shift the way in which they approach vaccine hesitancy to put individuals and their experiences first:
“I think the most important thing is to find common ground, just to find shared values, understand people, understand them as people, as opposed to just [thinking of them as] statistics, […] understand historical context, empathize.”

Statins were first approved by the Food and Drug Administration (FDA) in 1987.
Updated guidelines from the U.S. Preventive Services Task Force (USPSTF) suggest that statins benefit those ages 40 to 75 with at least one risk factor for cardiovascular disease.
However, questions remain about who exactly can benefit from them.
Cardiovascular disease is the leading cause of death and disability globally, and there have been concerted efforts for decades to prevent and minimize its impact.
Lifestyle interventions are important for preventing cardiovascular disease, with smoking, obesity, diabetes, lack of physical exercise, and excessive consumption of alcohol all increasing the risk of developing cardiovascular disease. Statins are also an important pharmaceutical option for lowering cardiovascular disease in people at risk. It was estimated that more than 173 million people took statins in 2018.
Evidence published in the journal The Lancet in 2010 shows that reducing low-density lipoprotein cholesterol by 1mmol/L with statins reduces the risks of ischaemic heart disease and stroke by 24{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} to 25{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809}.
Statins reduce the risk of cardiovascular disease by lowering the level of low-density lipoprotein (LDL) cholesterol in the blood. Too much LDL cholesterol can build up as “plaques” in your blood vessels and narrow their diameter. Over time this narrowing can block blood flow to certain organs. If blood flow to the heart is blocked, it can cause a heart attack, and if it occurs in the brain, it can cause an ischemic stroke.
Targeting the right patients with statins is key to gaining the most benefit. The U.S. Preventive Services Task Force (USPSTF) recently published its Recommendation Statement for Statin Use for the Primary Prevention of Cardiovascular Disease in Adults in the Journal of the American Medical Association (JAMA). The recommendations were both slightly more conservative but also very similar to existing recommendations by the American College of Cardiology (ACC) and the American Heart Association (AHA).
The new guidance was published following an evidence review that included 22 randomized clinical trials, including additional data from three randomized control trials not included in the last set of guidelines published in 2016. On the back of this, they have issued three main recommendations for clinicians dealing with patients.
They advised:
Statin use would yield moderate benefit for those ages 40-75 with one or more factors that could increase the risk of cardiovascular disease, no history of cardiovascular disease, and an estimated 10-year cardiovascular event risk of 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} or greater.
Those of the same age with the same risk factors with a 10-year cardiovascular event risk factor of 7.5{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} to 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} will have a small net benefit from taking statins.
However, there was not enough evidence to determine whether it’s beneficial to initiate statin use in those older than 75.
Dr. Edo Paz, cardiologist and VP of Medical at K Health, told Medical News Today in an email:
“In these updated guidelines, the USPSTF recommends that clinicians assess a patient’s risk of having a cardiovascular event (like a heart attack or stroke) to decide which patients should be treated with statin therapy.
The ACC/AHA also gives additional guidance around the intensity of statin therapy, differentiating between moderate and high intensity options. Overall, the USPSTF guidelines are a bit simpler, as it is geared to all primary care doctors, rather than to cardiologists.”
In the same week, a model was presented at the European Society of Cardiology Congress 2022 which echoed the findings of the review, supporting the use of statins in patients over 40 with high cardiovascular disease risk.
The study created a model using data from 118,000 participants of the Cholesterol Treatment Trialists’ Collaboration and 500,000 individuals from the UK Biobank. It looked specifically at the difference between continuing statins for life, compared to stop taking them at 80, as there is little evidence of their value in people older than age 75.
Lead author Dr. Runguo Wu of the Queen Mary University of London said: “Our study suggests that people who start taking statins in their 50s but stop at 80 years of age instead of continuing lifelong will lose 73{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of the QALY benefit if they are at relatively low cardiovascular risk and 36{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} if they are at high cardiovascular risk – since those at elevated risk start to benefit earlier.
“Women’s cardiovascular risk is generally lower than men’s. This means that for women, most of the lifelong benefit from statins occurs later in life, and stopping therapy prematurely is likely more detrimental than for men.”
Rather than suggest that statin treatment was potentially controversial, clinicians should focus on the areas where statin guidelines overlap, said Prof. Salim Virani, professor of Cardiology at Baylor College of Medicine, Houston, TX, and one of the authors of the ACC/AHA Primary Prevention Guideline from 2018.
In an editorial published by the JAMA in the same issue as the USPSTF Recommendation Statement, Prof. Virani outlined that the review of the data did not find “any significant harm associated with statin therapy,” and called the recommendations “sensible and practical.”
In an interview with MNT, he explained that the main difference between these guidelines and the 2018 ACC/AHA guidelines was over whether the cut-off for introducing statins was for people with a 7.5{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} 10-year risk of cardiovascular disease as is the case with the ACC/AHA guidelines, or 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} as is the case with the most recent guidelines from the US Preventive Services Task Force.
“Most of the patients whose 10-year risk is 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} or higher, well, they have to be treated based on both the guidelines,” said Prof. Virani. He added that further modeling of how many people these slight differences would affect was due to be published in the coming weeks.
Prof. Virani explained that individual risk factors needed to be considered by clinicians and patients when considering whether or not they needed to initiate statin treatment. While risk factors such as obesity and diabetes were considered in both sets of guidelines, the guidelines from USPSTF did not mention South East Asian ancestry or pre-eclampsia, or the risks for postmenopausal women for example.
“Last but not the least, the ACC/AHA guidelines have what we call these risk enhancers, which are factors that are not there when somebody is doing their tenure risk calculation but might be important for a patient, for example, a patient having family history of premature cardiovascular disease, those patients need to be treated early, and the ACC/AHA guidelines account for those factors as well, which is notion the US Preventive Services Task Force recommendations.”

Researchers examined the romantic relationship concerning mind age and numerous wellbeing indicators.
They observed that very poor cardiovascular health was associated with more mature brain age, which was connected to poorer cognitive effectiveness, and a lesser brain volume.
They concluded that further more investigation is desired to comprehend no matter whether their findings utilize to various demographics.
As the human mind ages, its construction modifications. A person’s ‘brain age’ can be predicted by a laptop design. This strategy works by using MRI-based device discovering to assess an individual’s neuroanatomy with a significant reference set of wholesome brains.
If you subtract mind age from a person’s chronological age, you can compute their brain-predicted age variation (mind-PAD).
Reports have discovered that brain-PAD can predict the 8-year mortality of 70-year-olds and indicate chance for various problems, such as dementia, numerous sclerosis, and depression.
Researching how mind age interacts with other physiological health steps and health and fitness results could strengthen our being familiar with of the getting older course of action.
In a new review, scientists examined how brain-PAD relates to many well being results in excess of the lifespan.
They discovered that mind PAD is linked to cardiovascular risk and neurodegeneration. They observed that their findings might be practical for knowledge individual prognoses.
For the examine, the scientists bundled data from 456 individuals who were being born in the exact week of 1946 in Britain. Just about every person underwent 24 distinctive assessments given that delivery on various variables, together with:
childhood cognitive skill
grownup cognition
adult socioeconomic situation
cardiovascular actions (i.e., blood pressure, using tobacco position, and diabetic issues record at ages 36 and 69)
polygenic hazard score (genetic possibility for a variety of health conditions)
MRI mind scan between 2015 and 2018
While members were an typical of 70.7 yrs outdated at the time of the review, their average mind-predicted age was 67.9 years. Female brains ended up an ordinary of 5.4 years younger than male brains following adjusting for chronological age.
The researchers observed that brain age was significantly joined to higher cardiovascular threat, poorer cognitive performance, and a smaller brain volume.
They also located that an more mature mind age was joined to larger levels of neurofilament light-weight protein (NfL). Though NfL ranges raise with age in wholesome people today, they are also joined to neural harm.
Mind-PAD was more joined to long term hippocampal atrophy, an early attribute of Alzheimer’s sickness. Nevertheless, the researchers uncovered no link between mind-PAD and different biomarkers for Alzheimer’s condition.
The scientists also claimed no considerable connection among mind-PAD and childhood cognitive performance, training level, or socioeconomic status.
All round, they claimed that the 12 metrics accounted for in their review could demonstrate 33{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of the variance in mind-PAD.
When requested what could describe the romance among cardiovascular overall health and aging in the brain, Dr. Aaron Wagen, scientific research fellow at University University London, just one of the study’s authors, advised Healthcare News Nowadays:
“The brain is the most vitality demanding organ in the human body, and so involves a regular offer of oxygen.”
“Any harm to the vascular program (e.g., heart, blood vessels) that impacts the stage of oxygenated blood supplied to the mind will have a adverse effect on mind wellbeing, probably ensuing in cerebral modest vessel ailment, white make any difference lesions, and mind atrophy. These brain adjustments can occur as aspect of normal ageing. Even so, lousy heart overall health could imply they materialize previously than expected.”
— Dr. Aaron Wagen
Dr. Lee A. Baugh, an affiliate professor of neuroscience at the College of South Dakota, who was not associated in the examine, also told MNT that cardiovascular hazard aspects, these kinds of as blood tension and smoking status, have presently been connected to untimely brain ageing.
“The exact mechanisms by which cardiovascular overall health and getting old in the mind are joined are possible amazingly difficult, but will absolutely have to do with issues these kinds of blood circulation shipping and delivery to the brain, cardiac hemodynamics, and arterial stiffness,” Dr. Baugh stated.
“I assume the more thrilling problem is whether or not the composite measurement of cardiovascular wellbeing utilised in the present research is offering exceptional info over and outside of what these personal things present, and the remedy to that dilemma really calls for even further research. That getting explained, it is terrific to see these varieties of connections being made amongst mind and entire body overall health,” he additional.
MNT also questioned the scientists what might clarify the variances in mind age in between men and ladies.
“In this cohort, we have noticed that women outperform males in many measures, which includes cognitive checks. The more youthful mind predicted age viewed in females might replicate this, [alongside] in common the variances in existence expectancy in the U.K. population where by girls stay more time than guys. The mechanisms underlying this need further more examine, but cardiovascular health may possibly contribute,” Dr. Wagen claimed.
The scientists concluded that their conclusions would enable further more exploration into mind age and predict future drop.
As for the study’s constraints, Dr. Wagen noted that his research was done mainly on white British participants, and thus could not implement to other demographics.
Dr. Baugh pointed out that because of to how some of the statistical analyses had been carried out, there is an elevated probability of bogus optimistic final results or findings that do not exist. He mentioned that long run investigate should really examine the relationships with much more “conservative statistical ways.”
He added that there are now multiple strategies to determine mind age other than that made use of in the research and that even more analysis is wanted to recognize which is optimal.
New means to evaluate brain age
“It will be important for the industry to arrive up with standardized, nicely-validated techniques to measure brain age to allow for the comparison throughout study experiments, and especially essential if effects like these are finally applied to guideline healthcare choices. It is this latter scenario that I imagine is the really interesting probable for this sort of investigate.”
— Dr. Lee A. Baugh
To support avoid premature brain growing old, experts advise quite a few techniques to minimize cardiovascular chance aspects.
“Being physically energetic, handling current professional medical problems, taking in nutritious, understanding how to regulate tension correctly, keeping engaged in social networks and things to do [are crucial],” Dr. Baugh claimed.
“These are all factors that we know can have a major influence on cardiovascular and mind overall health, fundamentally retaining the full overall body as ‘young’ as possible,” he added.
