title: Prognosis of acute myocardial infarction using systolic time intervals recorded on the carotidogram.
abstract: The prognostic value of systolic time intervals and of other clinical and laboratory parameters was investigated in 68 patients with acute myocardial infarction (AMI) (55 males and 13 females; mean age 61 years) over a period of one month after onset of the disease. The statistical analysis of data was made by the STR stepwise regression method, using an IBM--360 computer. Finally the study resulted in a stepwise multiple regression equation with 4 factors of maximum statistical significance in the prognosis of AMI: peak SGOT level, age of patients, uncorrected left ventricular ejection time and index of preejection period. This new prognostic index allows a classification of patients with acute myocardial infarction (starting with the second day after onset) into groups of various severity, thus helping the practitioners in the choice of therapy.
