Effect of physical training after myocardial infarction on the functional state of myocardium

Effects of 4 months of physical training on cardiac pump function were asse ssed by exercise radionuclide ventriculography in 37 men who had undergone Q-wave myocardial infarction. Results were compared with data obtained from 28 similar patients not subjected to training. Exercise tolerance and thre shold values of heart rate, cardiac output, cardiac index and maximal filli ng velocity rose in the training group. An increase of left ventricular eje ction fraction occurred in patients with its initial values exceeding 35%.
