[Use of nifedipine and nitroglycerin during exercise therapy in patients with myocardial infarct. Clinical and hemodynamic studies].
The hemodynamic effects of nitroglycerin and nifedipin and the application of both substances during a long term training program in patients with angina pectoris, myocardial infarction, and myocardial dysfunction (=48) were studied. Cardiac output, heart rate, and arterial blood pressure showed no significant changes after application of nitroglycerin and nifedipin. After nitroglycerin, however, there were significant drops of pulmonary arterial pressure and right atrial pressure during rest and exercise, whereas no changes were seen after nifedipin. With the application of nitroglycerin (but not with nifedipin) prior to the daily physical training program on a bicycle ergometer, all patients with angina pectoris and myocardial dysfunction showed an increasing training effect during the long term program and their angina pectoris improved.
