[Return to work and cardiovascular status after myocardial infarction]

Area of Science:

• Cardiology
• Occupational Health

Background:

• Myocardial infarction (MI) survivors face challenges returning to work.
• Understanding factors influencing return-to-work and long-term health is crucial.

Purpose of the Study:

• To assess return-to-work rates and outcomes in male MI patients.
• To evaluate subjective health status and work capacity post-MI.
• To investigate cardiac function during normal workday activities.

Main Methods:

• Retrospective study of 110 male MI patients under 60.
• Post-discharge questionnaire assessing work status and health.
• Holter monitoring during a typical workday.
• Comparison of rehabilitated vs. non-rehabilitated patients.

Main Results:

• 72.1% of patients returned to work within an average of 4.8 months.
• Self-employed patients had higher return-to-work rates.
• 90.5% reported satisfactory health, though symptoms like heartburn and dyspnea were common.
• Workload was perceived as tiring by only 12.6%; 65.6% maintained work capacity.
• Holter monitoring showed no significant cardiac differences between working/retired or work/rest periods.
• Ventricular arrhythmias were present in 47.5%, often asymptomatic and high-risk.

Conclusions:

• Most male MI survivors under 60 can successfully return to work.
• Subjective health and work capacity are generally good post-MI.
• Normal workday activities do not appear to significantly worsen cardiac function.
• Asymptomatic ventricular arrhythmias are common and require further investigation.
