TUESDAY, June 5, 2018 (HealthDay News) -- If you're feeling overwhelmed at work, you'll want to read on.
Swedish researchers found the most stressful jobs were associated with nearly 50 percent higher odds of atrial fibrillation.
Folks at greatest risk? Those in psychologically demanding jobs that give employees little control over their work. For example, assembly line workers, bus drivers, secretaries and nurses, the researchers said.
The condition causes palpitations, weakness, fatigue, light headedness, dizziness and shortness of breath. It can also lead to stroke and premature death, the study authors explained in background notes.
Fransson cautioned that this kind of study cannot prove that job strain causes atrial fibrillation, only that the two seem to be associated.
For this study, Fransson and colleagues collected data on more than 13,000 people who took part in the Swedish Longitudinal Occupational Survey of Health in 2006, 2008 or 2010.
Survey questions asked about job strain: For example, Must you work very hard or very fast? Do you have enough time to complete your work tasks? Does your work include a lot of repetition? Can you decide how and what to do at work?
Over an average follow-up of six years, researchers identified 145 cases of atrial fibrillation.
People who reported the most stress were 48 percent more likely to develop atrial fibrillation than those with the least stressful jobs, Fransson said.
Fransson's team also pooled these data with results from two similar studies. In that analysis, the investigators found that job stress was associated with a 37 percent increased risk for atrial fibrillation.
Dr. Byron Lee, a professor of medicine at the University of California, San Francisco, said, "This study confirms the connection between stress and atrial fibrillation. Therefore, atrial fibrillation patients should try to reduce stress as much as possible."
Of course, any job can be stressful, said Fransson. Still, "work stress may be a modifiable risk factor for atrial fibrillation," she added.
But if changing to a less stressful job isn't possible, Lee suggests taking up an activity like yoga, which has been proven to reduce both stress and atrial fibrillation.
The report was published June 4 in the European Journal of Preventive Cardiology.
