In a groundbreaking study conducted by UC San Francisco, researchers have unveiled a compelling connection between inadequate sleep and heightened risks of experiencing atrial fibrillation (A-Fib) – a condition characterized by irregular heartbeats that may lead to serious cardiovascular complications. The findings emphasize the critical importance of obtaining sufficient rest for maintaining heart health.
According to the study, a single night of poor sleep was associated with a 15% increased likelihood of experiencing an A-Fib episode, while prolonged periods of subpar sleep were correlated with longer episodes of A-Fib.
Dr. Gregory M. Marcus, the corresponding author and a distinguished cardiologist and electrophysiologist at UCSF Health, stressed the significance of addressing underlying conditions contributing to A-Fib, the most prevalent form of arrhythmia. He further highlighted that enhancing overall sleep quality could be an effective strategy in mitigating these risks.
“Treating insomnia can be challenging, but in many cases, there are things within an individual’s control that can meaningfully improve sleep quality,” stated Dr. Marcus.
He recommended establishing a regular and reasonable bedtime routine, avoiding the consumption of alcohol and caffeine before sleep, reserving the bed solely for sleep or intimate activities, maintaining a consistent exercise regimen, keeping the bedroom at a cool temperature, refraining from daytime naps, and awakening at the same time each day.
UCSF, a renowned institution in the field of cardiology, has been at the forefront of advancements in the treatment of heart rhythm disorders. While previous research has extensively explored the risks associated with A-Fib, this study marks the first instance where a direct and immediate connection to poor sleep has been established.
The investigation involved the monitoring of 419 participants enrolled in the I-STOP-AFIB trial. Each night, participants self-reported their sleep quality using categories ranging from “amazing” to “horrible,” and mobile electrocardiograms were employed to assess A-Fib episodes occurring the following day.
The results of this groundbreaking study have been published in JACC: Clinical Electrophysiology.
