title: [Ergometric investigations with pressure measurements in the pulmonary arteria for judgment of the severity of the disease in patients suffering from left heart diseases (author's transl)].
abstract: Pressure measurements in the pulmonary artery were performed on 34 patients by intracardiac floating catheter during rest and under ergometer load of 51 Watt (corresponding to an oxygen consumption of 750 ml/min). 15 of the patients were suffering from myocardial infarction 4--6 weeks after admission, 12 from chronic coronary heart disease respectively angina pectoris and 7 from affection of the aortic valve. The pressure during rest ranged within the norm. Under load the patients suffering from myocardial infarction and coronary heart disease showed two forms of reaction: 1. moderate ascent of pressure up to 40 torr systolic and 15--18 torr diastolic (mean pressure 25--28 torr). 2. distinct ascent of pressure up to 50--60 torr systolic and 25--30 torr diastolic (mean pressure 36--42 torr). Evidence of latent pulmonary hypertension was irrespective of classification as myocardial infarction with or without complications. That demands regarding of central hemodynamics for the further course of rehabilitation more than hitherto.
