Study finds only alcohol triggers heart arrythmia


The study is published in the ‘JAMA Cardiology Journal’. The authors concluded that people may be able to reduce their risk of atrial fibrillation (AF) by avoiding certain triggers.

New Delhi: According to research from UC San Francisco, it was found that while normal heart conditions result from caffeine, lack of sleep, and sleeping on the left side, alcohol is the only one that was associated with heart arrhythmias (inappropriate heartbeat). whether erratic, too fast or too slow).

The study is published in the ‘JAMA Cardiology Journal’. The authors concluded that people may be able to reduce their risk of atrial fibrillation (AF) by avoiding certain triggers.

The researchers were surprised to find that although most of the things the participants thought would be related to their AF, those in the intervention group still experienced fewer arrhythmias than those in a comparison group that did not self-monitor. Was doing.

“This suggests that those individual assessments revealed actionable results,” said lead author Gregory Marcus, MD, professor of medicine in the Department of Cardiology at UCSF.

“Although caffeine was the most commonly selected trigger for the trial, we found no evidence of a near-term association between caffeine consumption and atrial fibrillation. In contrast, alcohol consumption consistently displayed an increased risk of atrial fibrillation.”

Atrial fibrillation contributes to more than 150,000 deaths each year in the United States, reported the federal Centers for Disease Control and Prevention, with mortality rates rising for more than 20 years.

To learn more about what patients felt about the disease as particularly important to the study, researchers conducted a brainstorming session in 2014. Patients stated that researching the different triggers for AF was their top priority, leading to the I-STOP-AFib study, which enabled individuals to research the different triggers for AF. To test any presumed AF trigger. About 450 people participated, of whom more than half (58 percent) were men, and the majority of whom were white (92 percent).

Participants in a randomized clinical trial underwent a mobile electrocardiogram with a phone app to log potential triggers such as drinking alcohol and caffeine, sleeping on the left side or not getting enough sleep, eating a large meal, a soft drink, or clinging. Recording device used. Engaging in a special diet, exercise, or anything else they thought was relevant to their AF.

Although participants were most likely to select caffeine as a trigger, this had no association with AF. Recent research from UCSF has similarly failed to demonstrate an association between caffeine and arrhythmias – on the contrary, investigators found that it may have a protective effect.
The new study showed that alcohol consumption was the only trigger that resulted in more frequent self-reported AF episodes.

The individual test method, known as n-of-1, did not validate participant-selected triggers for AF. But trial participants reported fewer AF episodes than the control group, and the data suggest that behaviors such as alcohol avoidance may reduce the likelihood of having an AF episode.
“This completely remote, siteless, mobile-app-based study will hopefully pave the way for multiple investigators and patients alike to conduct personalized “n-of-1” experiments that are clinically relevant to the individual. can provide information,” Marcus said. (ANI)
