To determine the characteristics of postoperative homodynamics following aortocoronary bypass surgery (CABG) and mitral valve surgery, twenty three patients (13 patients undergoing CABG, 10 patients undergoing mitral valve surgery) were studied. Sequential hemodynamic measurements during early postoperative period revealed the following : (1) Sydtemic hypertension caused by elevated systemic vascular resistance was seen immedietely after aortocoronary bypass surgery, and it induced a deterioration of cardiac performance. (2) In the patients undergoing mitral valve surgery. Central venous pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure and pulmonary vascular resistance were significantly higher than those in the patients undergoing CABG during 24 hours postoperatively. (3) Cardiac index and left ventricular stroke work in the CABG group showed better improvements in late study period than those in the mitral valve group, according to reduction in systemic vascular resistance. (4) Preperative pulmonary hypertension associated with mitral valve disease decreased significantly after surgery, but there were some patients demonstrated no significant reduction in pulmonary vascular resistance. The results suggest that the homodynamic alterations during postperative period were influenced by peripheral vascular resistance and preexsting disease.
