    Executive staff had higher diastolic blood pressure and engaged in less leisure exercise than production-line workers. However, occupational factors did not appear to induce heart rhythm disturbances like ventricular premature beats (VPB) in either group.

    Area of Science:

    • Occupational Health
    • Cardiology
    • Preventive Medicine

    Background:

    • Previous research indicated lower heart attack incidence in car plant production-line workers compared to executives.
    • Coronary heart disease risk factors and cardiac rhythm are crucial in occupational health studies.

    Purpose of the Study:

    • To investigate major coronary risk factors and cardiac arrhythmias in production-line workers versus executive staff.
    • To determine if occupational factors influence heart rhythm disturbances.

    Main Methods:

    • Two age-matched groups of 30 middle-aged men (production-line workers and executives) were studied.
    • 24-hour ambulatory electrocardiograms and assessment of coronary risk factors were performed.
    • Men with pre-existing heart disease were excluded from the study.

    Main Results:

    • Executive staff exhibited significantly higher average diastolic blood pressure compared to production-line workers (P < 0.05).
    • Executive staff reported significantly less heavy leisure-time exercise than production-line workers (P < 0.05).
    • Ventricular premature beats (VPB) and other arrhythmias were infrequent and similar across work, leisure, and sleep periods for both groups.

    Conclusions:

    • Higher diastolic blood pressure and lower leisure exercise levels are associated with executive roles.
    • Occupational factors do not appear to be a significant trigger for arrhythmias like VPB in this study population.
