While the link between job strain, effort-reward imbalance, and coronary heart disease is well documented, a recent study published in the Journal of the American Heart Association reveals a new and concerning dimension to work-related stress.
The research indicates that these stressors may also increase the risk of developing atrial fibrillation (AFib), a serious heart rhythm disorder.
This finding highlights the broader cardiovascular impacts of job-related stress, extending beyond traditional heart disease to disrupt heart rhythms.
Led by Xavier Trudel, an occupational and cardiovascular epidemiologist at Laval University, Canada, the study examined medical database records of nearly 6,000 white-collar workers in Canada over 18 years.
“This research is the first to assess the impact of workplace psychosocial stressors on AFib,” said Trudel as he emphasised the need to incorporate work-related stress factors into preventive strategies, advocating for healthier work environments to benefit both individuals and organizations.
AFib, characterized by an irregular and often rapid heart rhythm, can lead to blood clots in the heart, significantly increasing the risk of stroke, heart failure, and other cardiovascular complications.
Dr Vanita Arora, Clinical Lead—Cardiac Arrhymias and Pacing Indraprastha Apollo Hospital, Delhi who is not associated with the study called it a serious observation which needs more awareness particularly in the context of India where lifestyle changes are resulting into stress and non-communicable diseases. She added that triggers can also be due to thyroid but stress remain a bigger cause.
Dr Arora explained, “Atrial fibrillation (AFib) is a type of arrhythmia characterized by an irregular and often rapid heart rhythm.
This condition can lead to the formation of blood clots in the heart, which significantly increases the risk of stroke, heart failure, and other serious heart-related complications.
As AFib disrupts the heart’s normal rhythm, it poses a substantial threat to cardiovascular health, making its early detection and management crucial.”
Dr Arora further said that if noticed regularly, we recommend Radio Frequency Ablation. But most important is that one should avoid triggers like keeping the thyroid and stress level under control.
The study in question had analyzed 5,926 workers (49% men, 51% women) with an average age of 45 at the start and 65 by the end of the follow-up period. Out of these, 186 cases of AFib were identified.
Among those with AFib, 19% reported high job strain, 25% experienced effort-reward imbalance, and 10% reported both stressors. Notably, over one-third of these participants had been diagnosed with coronary heart disease or heart failure prior to developing AFib.
This research underscores the critical need for employers and employees to recognie and address the psychological and physiological impacts of job stress, aiming to foster environments that promote overall cardiovascular health.
More than one-third of participants were diagnosed with coronary heart disease or heart failure before their AFib incidence.
