Pressure measurements in the pulmonary artery were performed on 34 patients by intracardiac floating catheter during rest and under ergometer load of 51 W (corresponding to an O2 consumption of 750 ml/min). Of the patients, 15 were suffering from myocardial infarction 4-6 wk after admission, 12 from chronic coronary heart disease, particularly angina pectoris, and 7 from aortic valve disease. The pressure during rest ranged within the norm. Under load the patients suffering from myocardial infarction and coronary heart disease showed 2 forms of reaction: moderate ascent of pressure up to 40 torr systolic and 15-18 torr diastolic (mean pressure 25-28 torr); and 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. Central hemodynamics should be monitored to determine further the course of rehabilitation.
