CHICAGO — Atrial fibrillation admissions were more likely to occur in the beginning of daylight saving time compared with the end of daylight saving time, according to an abstract presented at the American Heart Association Scientific Sessions.
“Our study adds atrial fibrillation as a known condition associated with daylight saving time,” Jay Chudow, MD, resident at Montefiore Medical Center in the Bronx, New York, told Cardiology Today. “It adds to the knowledge base of negative health consequences of daylight saving time.”
Researchers analyzed data from 6,296 patients (mean age, 68 years; 53% women) who were admitted for AF from 2009 to 2016.
More patients with AF were admitted on the Monday through Thursday following the start of daylight saving time compared with the yearly mean of the same time period (3.13 admissions per day vs. 2.56 admissions per day; P = .025). This increase was not observed in the Monday through Thursday after daylight saving time ended.

“The exact link between atrial fibrillation and daylight saving time transitions is not clear,” Chudow said in an interview. “It may be similar to the association between atrial fibrillation and sleep-breathing disorders, such as obstructive sleep apnea. Further research is needed to explore these connections.” – byDarlene Dobkowski
