[Different methods of myocardial revascularization in non-stable stenocardia].
The purpose of the study was to evaluate different methods of myocardial revascularization. Three hundred and twenty-two patients with non-stable stenocardia were divided into two groups: group one consisted of 226 patients with mono-, bi-, or tri-vascular lesion of the coronary arteries (CA), who underwent percutaneous coronary intervention (PCCI) on the symptom-related CA (128 patients) or coronary bypass surgery (CBS) without cardiopulmonary bypass (59 patients); group two consisted of 96 patients with tri-vascular lesion of CA only, who underwent CBS with cardiopulmonary bypass (CPB) (32 patients) or without CPB (52 patients). The rest patients in both groups received drug therapy. The data from the research show that PCCI on the symptom-related CA is the method of choice in most patients, including those with tri-vascular lesion. In cases with extensive isolated stenosis of anterior descendent coronary artery and chronic occlusions preference may be given to CBS without CPB. CBS with CPB is the method of choice in patients with left CA trunk stenosis and left ventricular dysfunction. In this group of patients, CBS without CPB does not lead to complete myocardial revascularization and thus does not make surgery successful.
