    Abstract:
    The aim of the present study is to separate the most important in-hospital and long term outcome risk factors in patients with myocardial infarction. We analysed 251 women and 630 men hospitalised for acute myocardial infarction between 1992-96. We compared history data, in-hospital course and long term observation within 2-6 years in a group of patients who died versus group of patients who survived. The most important risk factors of in-hospital death were: cardiogenic shock--with mortality rate--6.2, pulmonary oedema--2.8, ventricular fibrillation--2.7, third degree A-V block--2.5, supraventricular arrhythmia (atrial flutter, atrial fibrillation--2.4, previous myocardial infarction--2.4, diabetes--2.0, disturbances of intraventricular conduction--1.8. The most important risk factors of long term outcome were: congestive heart failure--III, IV class of NYHA at discharge--mortality rate--3.0, ejection fraction < 40%--2.7, disturbances of intraventricular conduction--2.2, in-hospital cardiogenic shock and/or oedema pulmonum--2.0, prior myocardial infarction--1.9, diabetes--1.7, in-hospital ventricular fibrillation--1.6, supraventricular arrhythmia--1.6. Better predictors of survival we can obtain using multivariate analysis. This analysis allows to separate groups of patient with good, mean and poor prognosis which finally simplify choice of efficient kind of therapy.
