Surgical Treatment of Angina Pectoris:VI. Pre- and Postoperative Haemodynamic Evaluations

Abstract

The pre-opsrative haemodynamic variables for 43 male patients with IHD divided at random into two groups were studied with the right heart catheterization technique before surgery intended to revascularize the myocardium. Thirty-one of these patients were also studied 1 year after surgery. The results of the initial studies show that the patients had a hypokinetic-hyperpyesic circulatory adjustment to exercise with findings indicating acute left ventricular failure due to ischae-mic myocardial dysfunction. The findings were identical for the two groups of patients. The postoperative control studies showed, in spite of several individual improvements, a general decline in myocardial function in the Beck group and no change in the graft group.
