    Abstract:
    The analysis of the first 125 patients, having coronary artery bypass surgery at the community hospital of Linz/Austria, revealed a perioperative mortality of 3% (n = 4) and a myocardial infarction incidence of 4% (n = 5). The angiographic restudy after surgery in 109 patients demonstrated 89% (n = 174) of the 196 vein grafts patent. The degree of revascularisation was 74% and the mean number of grafts per patient 1.8. The ejection fraction of the left ventricle was unchanged postoperatively (preop.: 61%, postop.: 64%). 3 to 6 months after surgery 55% of the patients were without angina pectoris-symptoms, 37% were clinically improved and 8% remained unchanged or deteriorated with respect to chest pain. There was a significant difference in patency rate and degree of revascularisation between pain free (90 resp. 88%) and improved patients (70 resp. 54%, p less than 0.001) and the unchanged (20 resp. 17%, p less than 0.001). Aortocoronary bypass surgery provides relief of pain or improvement in a high percentage (92%). The results are important influenced by graft function and degree of revascularisation.
