Abstract

We describe the 2- and 5-year prognoses following coronary artery bypass grafting (CABG) in relation to smoking habits among consecutive patients being operated on in western Sweden during a 3-year period. Among the 2,121 patients, 10.2% admitted smoking at coronary angiography as compared with 7.5% 2 years after CABG (NS). Among smokers, the mortality during the subsequent 2 years was 8.9% as compared with 6.5% for exsmokers and 7.3% for never smokers (NS). During the 5-year follow-up, smokers had a mortality of 18.8% as compared with 13.6% for exsmokers and 12.5% for never smokers (p = 0.03). When correcting for dissimilarities in previous history, smoking was a strongly significant independent (p < 0.0001) predictor of 5-year mortality.

摘要

我们描述了瑞典西部连续3年接受冠状动脉旁路移植术（CABG）的患者的2年和5年预后情况，并将其与吸烟习惯相关联。在这2121例患者中，10.2%的患者在冠状动脉造影时承认吸烟，而冠状动脉旁路移植术后2年这一比例为7.5%（无统计学差异）。在吸烟者中，随后2年的死亡率为8.9%，既往吸烟者为6.5%，从不吸烟者为7.3%（无统计学差异）。在5年随访期间，吸烟者的死亡率为18.8%，既往吸烟者为13.6%，从不吸烟者为12.5%（p = 0.03）。在校正既往病史的差异后，吸烟是5年死亡率的一个极具统计学意义的独立预测因素（p < 0.0001）。
