In a new study from the University of California, San Francisco, which tested possible triggers for common heart disease such as caffeine, sleep deprivation, and left-sided sleep, alcohol use alone was consistently associated with more episodes of arrhythmias. I found out that there is.
The authors conclude that avoiding certain triggers may reduce the risk of atrial fibrillation (AF).
The study is published at JAMA Cardiology It was presented at the American Heart Association’s annual science session on November 14, 2021.
Researchers were surprised to find that people in the intervention group had less arrhythmias than people in the non-self-monitoring comparison group, although most of what participants thought were related to their AF. rice field.
“This suggests that these personalized assessments have revealed practical results,” said lead author Gregory Marcus, MD, professor of heart disease at the University of California, San Francisco. Stated. “Caffeine was the most commonly selected trigger for testing, but no evidence of a short-term relationship between caffeine consumption and atrial fibrillation was found. In contrast. alcohol Consumption most consistently showed an increased risk of atrial fibrillation. “
Atrial fibrillation contributes to more than 150,000 deaths each year in the United States, the Federal Centers for Disease Control and Prevention reports, mortality rates have risen for over 20 years.
Researchers held a brainstorming session in 2014 to learn more about what patients felt was particularly important for studying the disease. Test the estimated AF trigger. About 450 people participated, more than half (58%) were male and the overwhelming majority were white (92%).
Participants in randomized clinical trials use a portable electrocardiogram recorder and phone app to drink alcohol and caffeine, sleep on the left side, do not get enough sleep, and eat large meals. , Drinking cold drinks, engaging in a particular diet, exercising, or anything else they thought was related to their AF. Participants were most likely to choose caffeine as the trigger, but it was not associated with AF. Similarly, a recent study at the University of California, San Francisco has failed to demonstrate a relationship between caffeine and arrhythmias. On the contrary, researchers have discovered that caffeine may have a protective effect.
New studies have shown that alcohol consumption is consistently the only trigger that has resulted in significantly more self-reported atrial fibrillation episodes.
A separate test method known as n-of-1 did not validate the AF trigger selected by the participants. However, study participants reported fewer AF episodes than the control group, and the data suggest that behaviors such as avoiding alcohol can reduce the likelihood of having AF episodes.
“This completely remote, siteless mobile app-based study provides similar personalized” n-of-1 “experiments that allow many researchers and patients to provide personalized, clinically relevant information. We hope to pave the way for implementation, “says Marcus.
