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.

In a significant case, the Supreme Court has allowed the medical termination of pregnancy of a 15-year-old girl who was over seven months pregnant.
Stressing that the choice of the pregnant woman must remain paramount, the SC bench led by Justice B V Nagarathna and Ujjal Bhuyan observed that a woman cannot be compelled to continue with an unwanted pregnancy merely on the ground that the child can be given up for adoption after birth.
However, AIIMS has sought a review of the order, citing medical ethics and the rights of an unborn child. The institution stated that it would lead to preterm delivery of a deformed baby needing prolonged NICU support.
The apex Court also issued a warning to the Union government of contempt proceedings if it failed to comply with its order, making it clear that the procedure must be carried out without delay.
The SC directed the termination of a fetus over seven months old of the 15-year-old girl, who was in a consensual relationship with a 17-year-old, admitted at AIIMS Delhi since April 10.
In India, medical abortion is allowed up to 20-24 weeks of pregnancy under the Medical Termination of Pregnancy (MTP) Act. However, in this case, the medical termination was allowed, giving primacy to the reproductive autonomy of the minor.
The Justices made it clear that “no court ought to compel any woman, and more so a minor child, to carry a pregnancy to full term against her express will.”
“If the pregnant woman carrying an unwanted pregnancy is compelled to continue such a pregnancy, then the constitutional rights of the pregnant woman would be breached,” noted the court.

However, Solicitor General Tushar Mehta, appearing before the court, told the bench that the child could be given up for adoption through CARA after being born. He told the bench that, as per medical reports, termination of pregnancy at this stage may be risky for both the mother and the unborn child.
But Justice Nagarathna warned that denying relief in such circumstances could expose women, especially minors, to grave risks, including resort to unregulated procedures that may cause irreversible harm.
The court also underscored the minor’s psychological distress, including reported attempts to take her own life, observing that forcing continuation of the pregnancy would have “long-lasting repercussions” on her mental health, education, social standing, and overall development, Law Beat reported.
Directing that the procedure be carried out at AIIMS Delhi with all necessary medical safeguards, the court required the minor’s guardian to submit an undertaking consenting to the termination.
AIIMS said the “unborn viable child” cannot speak for itself and depends on the court’s parens patriae jurisdiction to protect its right to life, The Times of India reported.
AIIMS, in its plea, said, “The court’s order proceeds on the premise of termination of pregnancy; however, the medical reality, as disclosed by the post-order assessment, is that a living, viable child will be prematurely delivered into the world.”
AIIMS also cited a fresh medical board opinion, saying the fetus is viable and preterm delivery could cause long-term disabilities and pose a grave risk to the minor mother. It said if the baby is carried to term, the state could care for it till adoption.
Referring to a similar case, AIIMS said a prematurely delivered baby continues to need NICU support, suffered repeated sepsis, and remains dependent on tracheostomy care.

Artificial Intelligence can fast-track better diagnostics, and even a cure for Alzheimer’s Disease, said OpenAI CEO Sam Altman.
In an exclusive interview with TODAY, Altman also announced that the OpenAI Foundation is pledging $100 million to Alzheimer’s research.
“AI has the potential to dramatically speed up how we discover treatments, improve diagnostics, and hopefully get us closer to a cure,” he said.
“This is one of the hardest problems in medicine - and one that affects millions of families. We felt we could help accelerate progress,” Altman added.
Alzheimer's disease is one of the most common forms of dementia, causing 60-70 percent of cases. It mostly affects adults over the age of 65 and is a leading cause of death and disability.
In a statement, OpenAI noted that Alzheimer’s is "one of the toughest problems in medicine".
"AI’s ability to reason across complex data could help researchers uncover new insights," it added.

“The OpenAI Foundation’s Alzheimer’s research initiative represents more than scientific progress. It’s a hope for millions of people, families, and anyone concerned about brain health. We applaud bold investments that prioritize speed and rigor, because every day matters. We must accelerate breakthroughs that change what it means to live with, or be at risk for, Alzheimer’s," said Joanne Pike, President and CEO of the Alzheimer’s Association.
What Is Alzheimer’s Disease?
Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.
While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet, and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.
There is no cure for this progressive brain disorder, and in advanced stages, loss of brain function can cause dehydration, poor nutrition, or infection. These complications can result in death.
About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US, 65 and older, live with the condition, and over 100,00 die from it annually.

South Carolina, which saw the largest measles outbreak in the United States in decades, has declared the outbreak over, state health officials announced.
The development comes as US cases reach 1,792, raising concerns about the country losing its measles elimination status achieved in 2000.
On Monday, health officials in South Carolina marked 42 days without new measles cases, confirming the outbreak that began in Spartanburg County last October has ended. There were nearly 1,000 confirmed cases over six months, including at least 21 hospitalizations.
On the upside, the outbreak led to a significant uptake in the measles, mumps, and rubella vaccinations. The state said 81,096 MMR vaccinations were given overall statewide, up 31.3 per cent from the previous year.
According to the public health experts, the increasing vaccination coverage played a significant role in helping to get the outbreak under control.
In a statement, South Carolina’s Department of Public Health’s Interim Agency Director, Edward Simmer, said that there was a 93.6 percent increase in MMR vaccinations during the outbreak.
The MMR vaccine is highly effective. One dose prevents the disease about 93 per cent of the time, and two doses raise that protection to 97 per cent.
“Vaccination – combined with other opportunities for good, solid public health work – really can be effective, even against some of the most contagious viruses,” said Dr. Brannon Traxler, deputy director and chief medical officer with the South Carolina Department of Public Health, CNN reported.
Notably, unvaccinated school-age children were the most affected by this outbreak, with 95.3 per cent of case-patients unvaccinated and 90.8 per cent of cases in children 17 years old and younger, CIDRAP news reported.
A total of 33 schools had measles exposures, and seven public school districts were affected. Over the course of six months, 874 students were asked to quarantine.

As per the Centers for Disease Control and Prevention's (CDC) latest weekly update, the US saw 44 new measles cases, one more than the 43 new cases confirmed the previous week. The national total now stands at 1,792 cases.
In 2026, 22 new outbreaks have been reported, and 93 per cent of confirmed cases are outbreak-associated. While there have been no deaths in 2026 from measles, six percent of case-patients (101 of 1,792) have been hospitalized this year in the US.
South Carolina also reported an additional measles case this month. However, it was determined not to be associated with the broader outbreak, but the single case exposed more than 40 people.
Utah reported five more cases in the past week, bringing the state total to 410 for 2026. Arizona has seven more cases, raising the 2026 total to 85. The four most recent cases came from Maricopa County.
“The re-emergence of measles in the Americas is a significant setback, but one that is entirely reversible and demands decisive action,” PAHO Director Jarbas Barbosa said in a press statement.
With several countries in the Americas, including Canada, Mexico, and the US, seeing a measles resurgence, the PAHO has urged leaders to increase MMR vaccination rates.
