Only alcohol — not caffeine, diet or lack of sleep — might trigger heart rhythm condition — ScienceDaily

New analysis from UC San Francisco that examined doable triggers of a typical heart condition, together with caffeine, sleep deprivation and sleeping on the left facet, discovered that solely alcohol use was persistently related to extra episodes of the heart arrhythmia.

The authors conclude that folks might be capable of scale back their danger of atrial fibrillation (AF) by avoiding sure triggers.

The research is revealed in JAMA Cardiology and was offered November 14, 2021, on the annual Scientific Sessions of the American Heart Association.

Researchers have been stunned to search out that though most of the issues that individuals thought could be associated to their AF have been not, these within the intervention group nonetheless skilled much less arrhythmia than the individuals in a comparability group that was not self-monitoring.

“This suggests that those personalized assessments revealed actionable results,” mentioned lead writer Gregory Marcus, MD, professor of medication within the Division of Cardiology at UCSF. “Although caffeine was the most commonly selected trigger for testing, we found no evidence of a near-term relationship between caffeine consumption and atrial fibrillation. In contrast, alcohol consumption most consistently exhibited heightened risks of atrial fibrillation.”

Atrial fibrillation contributes to greater than 150,000 deaths within the United States every year, studies the federal Centers for Disease Control and Prevention, with the demise fee on the rise for greater than 20 years.

To be taught extra about what sufferers felt was particularly vital to check in regards to the illness, researchers held a brainstorming session in 2014. Patients mentioned researching particular person triggers for AF was their high precedence, giving rise to the I-STOP-AFib research, which enabled people to check any presumed AF trigger. About 450 individuals participated, greater than half of whom (58 %) have been males, and the overwhelming majority of whom have been white (92 %).

Participants within the randomized scientific trial utilized a cellular electrocardiogram recording machine together with a telephone app to log potential triggers like consuming alcohol and caffeine, sleeping on the left facet or not getting sufficient sleep, consuming a big meal, a chilly drink, or sticking to a selected diet, partaking in train, or anything they thought was related to their AF. Although individuals have been almost certainly to pick out caffeine as a trigger, there was no affiliation with AF. Recent analysis from UCSF has equally didn’t display a relationship between caffeine and arrhythmias — quite the opposite, investigators discovered it could have a protecting impact.

The new research demonstrated that consumption of alcohol was the one trigger that persistently resulted in considerably extra self-reported AF episodes.

The individualized testing methodology, referred to as n-of-1, did not validate participant-selected triggers for AF. But trial individuals did report fewer AF episodes than these within the management group, and the information counsel that behaviors like avoiding alcohol may reduce the possibilities of having an AF episode.

“This completely remote, siteless, mobile-app based study will hopefully pave the way for many investigators and patients to conduct similar personalized “n-of-1″ experiments that can provide clinically relevant information specific to the individual,” mentioned Marcus.
