[Prognostic factors in the acute stage of myocardial infarction: analysis of 893 cases].
The prognostic factors in the acute stage of 893 myocardial infarction patients, admitted during a period from 1970 to 1986, were analysed. The overall mortality was 15.6%, including 14.4% cardiac death and 1.1% non-cardiac death. Single factor analysis indicated that age, sex, occupation, history of hypertension, chest pain during the episode, systolic blood pressure, heart rate and site of infarction at the time of admission, presence of complications such as cardiogenic shock, arrhythmias, stroke and monitoring in CCU or not were related to the overall mortality and cardiac death. Multiple factor logistic regression analysis indicated that for the overall mortality, the independent prognostic factors included presence of cardiogenic shock, heart rate and chest pain at the time of admission; for the cardiac death, the independent factors included age, occupation, history of hypertension, heart rate and chest pain at the time of admission, involvement of anterior wall and presence of cardiogenic shock and arrhythmias. Basing on the above findings we establish a risk factors predicting prognostic model of acute myocardial infarction in its acute stage.
