[Age dependency of pulmonary artery pressure after myocardial infarction at rest and during exercise (author's transl)].
Functional disorders of the left ventricle at rest and under 6 minutes lasting bicycle ergometer exercise of 50 W were studied in 249 patients after myocardial infarction. By means of well defined circumstances, measurement of pulmonary artery diastolic pressure with floating catheter allows evaluation of left ventricular enddiastolic pressure. The upper borderline of this pressure is 20 mmHg which was reached in 45% of patients in the age group under 40, in 75% in those who are 60 and older. Independent to other exercise limiting factors, like angina, ischemic ECG-changes, augmented heart volume, congestive heart failure or critical extrasystoles, it could be shown that measurement of pulmonary artery pressure in these cases is the base for rational therapy like administration of digitalis, vasodilator drugs or beta-adrenergic blocking agents. Furthermore it can be predicted wether physical training could be usefull or dangerous.
