Extended hours of work may increase risk for AF

Adults who work more than 55 hours per week are at higher risk for developing atrial fibrillation, according to a recent study in the European Heart Journal.

“Although the 2016 European Guidelines for [CVD] prevention acknowledges psychosocial stress at work as a potential risk factor for [CVD], citing evidence that show long working hours to be associated with increased stroke risk, little is known about the role of long working hours as a potential risk factor of atrial fibrillation,” Mika Kivimäki, PhD, of the department of epidemiology at University College London, and colleagues wrote. “In principle, stress and long working hours may enhance functional re-entry, repetitive pulmonary vein and atrial firing, and autonomic nervous system abnormalities, inducing arrhythmia vulnerability.”
