[Intraoperative hemodynamics in patients with pre-infarct stenocardia and acute myocardial infarct].
Intraoperative haemodynamics was studied in 31 patients with pre-infarction angina pectoris and in 3 patients with acute myocardial infarction. Twelve of them (3 with myocardial infarction) were subjected to a graphic examination of 12 haemodynamic parameters. Aorto-coronary bypass procedures using autovenous grafts were demonstrated to improve the contractile function of the left-ventricular myocardium in this group of patients, as manifested in a decrease of the binite diastolic pressure, increase of the cardiac index and stroke volume in the aorta. Tracing the intraoperative haemodynamics helps in determining the immediate postoperative prognosis and in choosing the optimum regimens of drug therapy. The determination of the volume blood flow in the bypass with the help of a flowmeter is a compulsory procedure, since it permits an objective assessment of the adequacy of the conducted revascularization of the myocardium.
