[Short and long term prognosis of patients with myocardial infarction. Hungarian Myocardial Infarction Registry].

INTRODUCTION

Mortality data of patients with acute myocardial infarction are incomplete in Hungary.

AIM

The aim of the authors was to analyse the data of 8582 myocardial infarction patients (4981 with ST-elevation myocardial infarction) registered in the Hungarian Myocardial Infarction Register in order to define the hospital, 30-day, and 1-year mortality. To evaluate the prehospital mortality of myocardial infarction, all myocardial infarction and sudden death were registered in five districts of Budapest.

METHOD

Multivariate logistic regression was performed to define risk factors of mortality and the model were assessed using c statistics.

RESULTS

The hospital, 30-day and 1-year mortality of patients with ST elevation myocardial infarction were 3.7%, 9.5% and 16.5%, respectively. In patients without ST elevation myocardial infarction these figures were 4%, 9.8% and 21.7%, respectively. The 1-year mortality of patients without ST elevation was higher than those of with ST elevation and the difference was statistically significant. Age, Killip class, diabetes mellitus, history of stroke and myocardial infarction were independent predictors of death. Coronary intervention improved the prognosis of patients with myocardial infarction significantly.

CONCLUSIONS

The rate of pre-hospital mortality was considerably high; 72.5% of 30 day mortality occurred before admission to hospital.
