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.

The experts stressed the urgent need to tackle India's growing obesity crisis—particularly among children.
Speaking during a panel discussion on the future of women's and child healthcare, Dr. Sivaranjani Santosh, often referred to as the "ORS Lady of India," praised India's public health achievements, including the successful Pulse Polio Program, malaria control efforts, and improvements in child nutrition.
However, she cautioned that new challenges now threaten the country's health gains.
"There were many things we are lagging a bit also," Dr. Santosh said, stressing the need for fair food labelling, responsible marketing, and stricter regulation of irrational drug combinations.
She issued a stark warning about unhealthy eating habits, saying, "This junk food pandemic, this is where India needs to really, really focus on. Childhood obesity is a pandemic now. And it's like do or die right now for us."
Her comments highlighted growing concerns that poor nutrition and processed foods are driving obesity among children, increasing their risk of chronic illnesses later in life.
Echoing the concerns, Dr. T. Rajeshwari Reddy, Senior Consultant Obstetrician, Gynecologist, and Laparoscopic and Robotic Surgeon at Continental Hospital, explained that unhealthy lifestyles beginning in childhood are now contributing to a rise in hormonal disorders, infertility, and high-risk pregnancies.
"We are seeing a lot of people with hormonal imbalances and a lot of issues from teens, and that is what gets translated into infertility and high-risk pregnancy," she said.
Dr. Rajeshwari stressed that prevention must begin early. "The beginning has to be from birth only," she said, urging families to prioritize home-cooked meals, healthy routines, adequate sleep, and reduced screen time. She added that preventive healthcare should become the foundation of India's health strategy over the next decade.
Experts agreed that the future of Indian healthcare will depend on preventive medicine, technology, artificial intelligence, and stronger public-private partnerships to improve access to healthcare, particularly in rural areas.
They urged that India's fight against childhood obesity and lifestyle-related diseases must begin at home, with healthier food choices, greater awareness, and prevention from an early age.
Meanwhile, the AI in healthcare panel featured Prof. Renu John, IIT Hyderabad; Nishan Ali, Founder & CEO, Neurologic AI; Dr. Rahul Sawakhande, CEO, Aakaar Medical Technologies; and Dr. Rajah V. Koppala, Vascular & Interventional Radiologist and Founder, AVIS Vascular Center.

The Ebola outbreak caused by the Bundibugyo virus has reached 915 confirmed cases and 210 deaths in the Democratic Republic of the Congo (DRC) and Uganda, according to the Africa Centers for Disease Control and Prevention (Africa CDC).
The situation remains serious, with ongoing transmission reported in eastern DRC. Ituri Province continues to be the epicentre of the outbreak, accounting for the majority of confirmed cases in the country. The most affected health zones include Bunia, Mongbwalu, and Rwampara.
North Kivu has reported fewer cases than Ituri but has recorded a higher case-fatality rate, particularly in Katwa and Beni. Health officials say this underscores the need for early detection, safe referrals, quality clinical care, and strengthened infection prevention and control measures.
In Uganda, 19 confirmed cases and two deaths have been reported to date. No new cases have been recorded since June 5, 2026.
Africa CDC has identified several challenges hampering response efforts, including gaps in
"Communities are central to stopping this outbreak. The response will only succeed if people trust the information they receive, know where to seek care, and feel that response teams are working with them," Africa CDC said in a statement.

Meanwhile, the World Health Organization (WHO) had warned that the outbreak is spreading rapidly, even as response measures are being intensified.
"The outbreak remains serious and is evolving very fast. However, I have seen a response that is growing stronger every day," said Marie-Roseline Belizaire, WHO Regional Emergencies Director for Africa, speaking to reporters in Bunia, the epicentre of the outbreak.
The WHO estimates that at least 95 per cent of contacts must be traced to effectively contain the outbreak. As per Belizaire, contact tracing has improved to 75 per cent.
Africa CDC epidemiologist Dr. Wessam Mankoula said the outbreak is approximately three times larger than any previous Ebola outbreak at a similar stage, four weeks after a public health emergency declaration, AP News reported.
Although the outbreak was officially declared on May 15, health officials believe the virus had been circulating undetected for some time beforehand, contributing to its wider spread.
Another major concern is that the outbreak is being driven by the Bundibugyo strain of Ebola virus, for which there are currently no approved antiviral treatments.
Community mistrust of healthcare workers and public health officials, along with reliance on traditional beliefs and healers, is also complicating containment efforts.

The US Food and Drug Administration's independent advisory panel has recommended approval of Moderna's mRNA-based influenza vaccine for older adults.
The panel backed the vaccine, known as mFLUSIVA, for adults aged 50 years and older, concluding that its benefits outweigh its risks.
If ultimately approved by the FDA, mFLUSIVA would become the world's first messenger RNA (mRNA) vaccine for seasonal influenza. The development could provide a new tool against a disease that causes an estimated 15 million to 60 million illnesses, 180,000 to 700,000 hospitalizations, and 17,000 to 75,000 deaths annually in the United States, according to data from the US Centers for Disease Control and Prevention (CDC).
The recommendation came from the Vaccines and Related Biological Products Advisory Committee (VRBPAC), which reviews vaccine applications and advises the FDA.
The meeting marked the committee's first review of a new vaccine application since 2023 and could lead to the first vaccine approval under the second Trump administration.
In a unanimous vote, all nine panel members supported the use of Moderna's mFLUSIVA vaccine for adults aged 50 to 64 years, as well as for those aged 65 years and older—the age group that had previously raised regulatory concerns.

However, before the vaccine can be made available for the upcoming flu season, it must receive formal FDA approval and be recommended by the CDC's Advisory Committee on Immunization Practices (ACIP). The CDC advisory panel has not recently convened due to ongoing legal and administrative challenges. An FDA decision on the vaccine is expected by August 5.
According to Moderna, the vaccine outperformed standard-dose flu vaccines in adults aged 50 to 64 years.
In a large clinical trial involving approximately 40,000 adults aged 50 years and older, Moderna's mRNA vaccine reduced influenza cases by about 27% compared with another routinely used flu vaccine.
The company also conducted a smaller study among adults aged 65 years and older. The results showed that mFLUSIVA generated a strong immune response compared with a high-dose influenza vaccine already recommended for seniors.
FDA adviser Dr. Anna Durbin of Johns Hopkins University described the immune-response data as "very compelling," adding that "the vaccine looks very promising," AP News reported.

Like Moderna's COVID-19 vaccines, mFLUSIVA uses messenger RNA technology. Rather than introducing a weakened or inactivated virus, mRNA vaccines deliver genetic instructions that help the body's cells produce proteins that trigger an immune response. This approach allows vaccines to be updated more quickly and may improve protection against evolving viruses.
Moderna's data showed no major safety concerns.
The most commonly reported side effects included:
These reactions were generally temporary and are commonly seen with many vaccines. However, they occurred somewhat more frequently than with currently available flu vaccines. FDA reviewers noted that this is typical of mRNA-based vaccines.
If approved, Moderna plans to conduct a large post-approval study involving approximately 400,000 adults aged 65 years and older.
Half of the participants will receive the mRNA vaccine, while the other half will receive one of the currently recommended flu vaccines for seniors. The study is expected to continue across two influenza seasons.
A Moderna executive said the company hopes to make the vaccine available to patients in time for the upcoming flu season, Reuters reported.
