Clinical characteristics, hospital care, and prognosis of patients with ST elevation myocardial infarction: Hungarian Myocardial Infarction Registry

The authors analyse clinical data, hospital care, and short-and long-term prognosis of 4981 ST segment elevation myocardial infarction (STEMI) patients enrolled in the web-based Hungarian Myocardial Infarction Registry. It has been found that the mean age of STEMI patients was lower by 5.3 years than that of patients treated for non-STEMI (NSTEMI). In the group of NSTEMI patients (n = 3601), the occurrence of diabetes, hypertension, peripheral vascular disease, and previous history of myocardial infarction and stroke were significantly more frequent. The proportion of smokers among STEMI patients was remarkably higher. Primary percutaneous coronary intervention (PPCI) was performed in 91.1% of STEMI patients. In the case of PPCI-treated patients, the median of 'door-to-needle time' was 45 min; the median of time from the onset of complaints to reperfusion was 210 min. The in-hospital mortality rate of STEMI patients was 3.7%, and 30-day and 1-year mortality rates were 9.5 and 16.5%, respectively. In the logistic regression analysis age, diabetes mellitus, a history of prior myocardial infarction and stroke, Killip class at admission, and PPCI proved to have prognostic significance. PPCI decreased the odds ratio for 30-day mortality by 71%, for 1-year mortality by 51%. The authors find the prospective clinical data collection (Infarction Registry) a valuable tool of quality control.
