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.
对在奥地利林茨社区医院接受冠状动脉搭桥手术的首批125例患者进行的分析显示，围手术期死亡率为3%（n = 4），心肌梗死发生率为4%（n = 5）。对109例患者术后进行的血管造影复查显示，196条静脉移植物中有89%（n = 174）通畅。血运重建程度为74%，每位患者的平均移植物数量为1.8。左心室射血分数术后无变化（术前：61%，术后：64%）。术后3至6个月，55%的患者无心绞痛症状，37%的患者临床症状改善，8%的患者胸痛症状无变化或恶化。无痛患者（分别为90%和88%）与症状改善患者（分别为70%和54%，p < 0.001）以及症状无变化患者（分别为20%和17%，p < 0.001）之间的通畅率和血运重建程度存在显著差异。主动脉冠状动脉搭桥手术能使高比例（92%）的患者缓解疼痛或症状改善。结果受移植物功能和血运重建程度的重要影响。
