OBJECTIVES:Examine short- and intermediate-term survival after coronary artery bypass grafting (CABG) and compare this to survival of the general population and to that predicted by EuroSCORE. DESIGN:One thousand three hundred and fifty one consecutive patients undergoing CABG were prospectively included. Survival status was ascertained through the Norwegian National Registry. RESULTS:Compared to the general population, no statistical significant difference in survival was seen in operated patients. Overall mortality rate was 0.8% after 30 days, 2.8%, 4.0% and 7.1% at one, two and three years, respectively. When patients were divided into four groups according to EuroSCORE, mortality increased significantly with increasing score, as expected. However, EuroSCORE overestimated mortality. CONCLUSION:Patients operated with CABG at our institution have similar survival as in the general Norwegian population. Although overestimating mortality by almost five-fold, we found a strong association between EuroSCORE and short-time survival, and an association between EuroSCORE and intermediate-term survival.

目的:检查冠状动脉搭桥术(CABG)后的短期和中期生存率,并将其与一般人群的生存率以及EuroSCORE预测的生存率进行比较。
设计:前瞻性地纳入了1351例连续接受CABG的患者。生存状况通过挪威国家登记处确定。
结果:与普通人群相比,手术患者的生存率无统计学差异。 30天后的总死亡率为0.8%,一年,两年和三年分别为2.8%,4.0%和7.1%。按照EuroSCORE将患者分为四组时,死亡率随着得分的增加而显着增加,这与预期的一样。但是,EuroSCORE高估了死亡率。
结论:在我们机构接受CABG手术的患者生存率与挪威普通人群相似。尽管高估了将近五倍的死亡率,但我们发现EuroSCORE与短期生存率之间存在密切关联,而EuroSCORE与中期生存率之间存在密切联系。
