  Abstract

Introduction: Acute myocardial infarction (AMI) is one of the most common causes of hospitalization and mortality in industrialized countries. Work disability is common in these patients. This study was aimed to learn the main demographic, professional and clinical variables which may Methods: In this study we surveyed 384 patients referred to Hazrat Rasoul Hospital from 2005 to 2008. The patients were interviewed through phone calls to collect data of return to work. Demographic, clinical and occupational variables were collected from the medical records.

Results: 79% of patients (303 patients) returned to work. The mean time the patients returned to work was 2.23 months (SD=2.2). Based on logistic regression analysis, predictor factors of returning to work were: age, duration of hospitalization, ejection fraction, history of diabetes mellitus, and occurrence of angina after AMI in hospital and CABG surgery (P-value<0. 05).

Conclusion: Successful return to work after first myocardial infarction is related to clinical, demographic, psychological and occupational factors. Also, based on the study results, precise evaluation of occupational factors such as job title, metabolic rate required for work and fitness for work may affect successful return to work.

  Key words: Myocardial Infarction, Return to Work, Work Capacity Evaluation
