[Effect of aorto-coronary bypass on function of cardiac ventricles as evaluated by non-invasive techniques during a two year observation].
In 1989-1990, 892 patients with ischemic heart disease were treated at the III Department of Cardiology in Katowice-Ochojec. Aortocoronary bypass was performed in 51 (5.7%) of these patients. Thirty five out of these patients were followed-up for 24 months after surgery. They reported to the hospital for evaluation after 3, 6, 12 and 14 months following a discharge. Efficiency of revascularization was checked with physical examination, and non-invasive tests such as electrocardiography, echocardiography and exercise tolerance testing. Diastolic and symbolic functioning of left and right ventricle was assessed separately. All patients suffered from anginal pain before surgery whereas 85% of operated patients were free from pain. No correlation between incomplete revascularization and recurrence of the anginal pain was noted. Surgery produced an increase in exercise tolerance and maximal load. No significant improvement in the right ventricle was seen during a 2-year follow-up. In the group of patients without previous myocardial infarction measured parameters of cardiac ventricles functioning were better than those in patients who had myocardial infarction. Therefore, the former are better candidates to coronary vessels revascularization.
