How Quitting Smoking Can Quickly Lower Risk Of A-Fib
Smokers who make the decision to quit will experience immediate health benefits, including a rapid reduction in their risk of atrial fibrillation (A-Fib), according to new research published in JACC: Clinical Electrophysiology. The study, conducted by Dr. Gregory Marcus, a cardiologist at the University of California, San Francisco, offers compelling evidence for smokers to quit, showing that it’s never too late to avoid the damaging effects of smoking on heart health.
Dr. Marcus, the senior author of the study, emphasized that A-Fib can be prevented even in individuals who have smoked for years. "The findings provide a compelling new reason to show current smokers that it’s not too late to quit, and that having smoked in the past doesn’t mean you’re ‘destined’ to develop A-Fib," Marcus explained. "Even for the current and longtime smoker, A-Fib can still be avoided."
"There’s strong evidence that smoking increases the risk of A-Fib," Marcus said. "But the benefits of quitting smoking have been less certain." With this in mind, his team sought to determine whether quitting could significantly lower a person’s risk of developing A-Fib, or if the risk would remain the same.
The research team analyzed data from over 146,700 current and former smokers, tracking their smoking habits and health over a 12-year period using data from the UK Biobank database. The results were promising: former smokers had a 13% lower risk of developing A-Fib compared to current smokers, while those who quit during the study saw an 18% reduction in their risk.
"This is likely a testament to the potency of reducing atrial fibrillation risk pretty shortly after quitting," Marcus said in a statement from the American College of Cardiology.
The findings highlight the importance of quitting smoking, not only for general health but specifically for reducing the risk of serious heart conditions like A-Fib.
Quitting smoking is one of the most effective ways to lower the risk of A-Fib and improve overall heart health. While it can be challenging, the benefits of quitting are clear and immediate. Here are some tips to help you quit smoking successfully:
1. Choose a specific date to quit smoking and stick to it. Prepare yourself mentally and physically for this change.
2. Reach out to family, friends, or a support group to help keep you accountable. Sharing your goals with others can provide encouragement.
3. Options like nicotine patches, gum, or lozenges can help ease withdrawal symptoms and reduce cravings.
4. Identify situations that make you want to smoke, such as stress or social gatherings, and find healthy ways to cope with them.
5. Regular exercise can help distract you from cravings and improve your mood during the quitting process.
6. Drinking water can help flush nicotine out of your system faster, reducing cravings.
7. Activities like yoga, meditation, or deep breathing exercises can help manage stress, a common trigger for smoking.
Quitting smoking offers immediate and significant benefits, particularly in reducing the risk of atrial fibrillation. The latest research provides smokers with more motivation to quit, showing that it's never too late to take control of their heart health.

For the first time, the US Congress is set to hold a dedicated hearing on menopause, putting a long-overlooked women’s health issue under the national spotlight. Convened by Sen. Kirsten Gillibrand (D-N.Y.), the hearing will be held by the Senate Committee on Aging.
Titled “Half the Country, Zero Hearings: Meeting the Moment to End the Menopause Care Gap in America,” the hearing will focus on the gaps in menopause research and care in the US.
Gillibrand is the senior Democrat on the committee and can lead one hearing each year on a topic of her choice. She chose menopause.
“It's time to talk about menopause. Half of our country will go through it, yet it is one of the most under-researched, undertreated, and underdiagnosed fields of medicine,” the 59-year-old Democrat leader shared in a post on X.
“This week, I'm holding the first-ever congressional hearing on menopause to demand high-quality research and care for women across America,” she added.
Gillibrand has described menopause as an issue that has long been ignored, particularly amid debates over the Trump administration’s scientific research cuts and health care affordability.

She said the hearing also aims to address the impact of menopause symptoms on women’s lives and sexual health.
“We spend billions of dollars on Viagra to make sure men can have sex — what have you done to make sure women can have sex?” she said, the New York Times reported.
Gillibrand also plans to call for bipartisan legislation to boost federal research on menopause.
“I’ve used my one hearing on the most under-researched, underreported, underanalyzed issue for women’s health, ever,” Gillibrand said. “From 50 to 58, I had either night sweats or hot flashes. I had to really look for a doctor who could take me through the hows and the whys and the impacts.”

Gillibrand said the government has long failed to devote federal resources to menopause and contended that the Trump administration has made the situation worse.
She cited the Food and Drug Administration’s recent decision to remove so-called black box warnings from all hormone replacement products containing estrogen.
“I’m wondering why they want women to have less information,” she said.
Menopause marks the end of a woman’s reproductive years and occurs when menstruation permanently stops.
Clinically, it is diagnosed after 12 consecutive months without a menstrual period.
Most women experience menopause between 45 and 55, although perimenopause can begin several years earlier.
During perimenopause, the ovaries gradually produce less estrogen and progesterone, the hormones that regulate the menstrual cycle. This hormonal decline can cause symptoms that vary widely among women.
While common symptoms including hot flashes and night sweats, sleep disturbances, mood changes and irritability and vaginal dryness, for some women the drop in estrogen levels can also be associated with health concerns including osteoporosis, heart disease and, in some cases, metabolic disorders.
Regular health checkups, balanced nutrition and physical activity during midlife are important. Hormone Replacement Therapy may also help manage menopause symptoms for some women, depending on their individual health profile and medical history.

Popular GLP-1 drugs Ozempic, Wegovy, Mounjaro and Zepbound have transformed the treatment of type 2 diabetes and obesity. However, a new study suggests they may be linked to a rare but serious brain disorder caused by vitamin B1 (thiamine) deficiency.
Researchers from Israel’s Sheba Medical Center identified 15 cases of Wernicke’s encephalopathy (WE) among people taking GLP-1 medications containing semaglutide or tirzepatide.
The findings suggest that nutritional deficiencies, particularly of vitamin B1, also known as thiamine, may contribute to the development of Wernicke’s encephalopathy.
Published in Clinical Nutrition, the study examined 195,979 cases and identified 15 reports of WE in 2023 and 2024.
Most patients experienced gastrointestinal problems, including severe vomiting, loss of appetite, malnutrition or rapid weight loss. These factors can reduce food intake and increase the risk of vitamin B1 deficiency.
Only two patients had the classic symptoms of WE: altered mental status, difficulty walking and abnormal eye movements.
Researchers described the findings as a potential safety signal and called for greater clinical awareness, particularly among patients experiencing severe gastrointestinal symptoms.
“WE is a potentially rare but severe adverse event of GLP-1 RA treatment, mainly with semaglutide or tirzepatide,” the researchers said. “As early detection may prevent neurological sequelae, increased clinical awareness is warranted, especially in individuals experiencing severe gastrointestinal symptoms.”
GLP-1 drugs suppress appetite and can reduce food intake, potentially limiting consumption of vitamin B1-rich foods such as pork, fish and whole grains.
Vitamin B1 is essential for proper nerve function. Without enough of it, patients can develop confusion, problems with balance and coordination, and abnormal eye movements.
In its early stages, thiamine deficiency can cause vague, nonspecific symptoms such as headaches, fatigue, irritability and abdominal discomfort.
Researchers said the findings should help doctors educate patients about the potential risk and monitor for warning signs.
Wernicke’s encephalopathy is a rare neurological disorder caused by severe vitamin B1 deficiency. Symptoms can include confusion, problems with coordination and abnormal eye movements.
The classic symptom triad is often absent, making the condition difficult to recognize. If untreated, WE can cause permanent neurological damage, progress to Korsakoff syndrome or result in death. Korsakoff syndrome is a permanent condition marked by memory loss, confusion, and changes in personality.
Experts do not recommend routinely taking supplements with GLP-1 drugs unless a deficiency is confirmed or nutritional needs cannot be met through diet.
A balanced diet containing fruits and vegetables, whole grains, nuts and seeds, dairy or fortified alternatives, and lean or plant-based proteins can help maintain adequate nutrient intake.
Experts also caution that products marketed specifically as “GLP-1 support” supplements may have limited evidence behind their claims.

The US Food and Drug Administration (FDA) has announced to hold a public hearing on the potential therapeutic use of psychedelic drugs, as the Donald Trump administration pushes to accelerate research and development of these treatments for serious mental illnesses..
The hearing, it said, will examine their potential use in supervised and supportive settings, including patient safety, provider training, access and data collection.
In a statement, the FDA said it is collaborating with federal partners and holding “this public hearing to obtain feedback and perspectives on issues associated with the potential future therapeutic use of drug products containing a psychedelic drug substance in supervised and supportive settings”.

The hearing will focus on what would be needed for the potential therapeutic use of psychedelic drugs in supervised and supportive settings.
Key areas include:
Emerging research shows psychedelics can help improve mental health, especially in conditions where traditional treatment approaches have not been useful. However, these drugs also come with several health risks that cannot be overlooked.
The hearing is part of broader US efforts to increase clinical trial participation, data sharing and real-world evidence on psychedelic drugs. The FDA hearing does not amount to approval of psychedelic treatments. Instead, it could help shape how the US approaches their potential future use in medical care.
The FDA has already taken steps to speed up the development of psychedelic treatments for mental health conditions.
In April 2026, the agency issued national priority vouchers to companies studying psilocybin for treatment-resistant depression (TRD), psilocybin for major depressive disorder (MDD), and methylone for post-traumatic stress disorder (PTSD).
The FDA has also granted Breakthrough Therapy designation to psychedelic drug programs involving MDMA for PTSD and psilocybin for TRD and MDD.
Research over the past decade has suggested that MDMA-assisted therapy may help reduce PTSD symptoms, while psilocybin-assisted therapy has shown promise for treatment-resistant depression in clinical studies.
For people who do not get lasting relief from existing treatments such as antidepressants and psychotherapy, psychedelic-assisted therapy could potentially offer another treatment option.
However, these designations and regulatory steps do not mean that these drugs have been approved as safe or effective treatments. Neither a national priority voucher nor Breakthrough Therapy designation is a substitute for FDA marketing approval.
The push has expanded beyond the FDA. In 2026, the White House, Congress and the Department of Veterans Affairs (VA) have also become involved in efforts to accelerate research into psychedelic treatments, including psilocybin, MDMA and ibogaine.
The US Department of Health and Human Services (HHS) has partnered with the VA to accelerate the development of psychedelic-assisted therapies for veterans with conditions including PTSD, depression and traumatic brain injury.
Separately, a bipartisan group of lawmakers introduced a bill that would require the US Department of Defense to evaluate whether ongoing psychedelic research, particularly involving psilocybin, could benefit active-duty service members and veterans transitioning to civilian life.
