Abstract
Aim. To analyze the influence of occupational role on long-term survival after myocardial infarction (MI).
Material and methods. The volume of selection was 471 patient; of those 342 men, 129 women. Among them at the moment of MI 118 had a job, and 353 had not. Comparison of survival was done by Kaplan-Meier method, criteria by Gekhan-Wilkokson. To eliminate the influence of gender and age on the statistics, before the risk assessment we directly standardized mortality by both these factors. For the risk of premature death in non-workers in comparison to current workers we measured an additional risk (EF) and odds ratio (OR) with 95% confidence interval (CI).
Results. Survival rate after MI in current workers group was higher than in nonworkers (p=0,00006). By the 8th year the level of survived among workers is 70%, and in non-workers — just 42%. The risks of premature death before 5 years after infarction in non-workers comparing to workers reach statistical significance: EF is 13,4% with 95% CI from 3,2% to 23,6%, OR is 1,78 with 95% CI from 1,14 to 2,78.
Conclusion. The results of the study witness higher survival rate in long-term period in currently working inhabitants than non-working, that presents even in first months after MI development. With the increase of time period from the onset of MI the differences in survival depending on occupation role getting more significant.
