Life-table analysis consecutive cases of isolated coronary bypass surgery at the Buffalo Hospital between 1973 and 1977 showed an estimated survival of 94 per cent at five years, equal to that of an age- and sex-matched group of the US population. Subsets of these patients divided according to sex, age, number of vessels narrowed, number of segments grafted, history of myocardial infarction, ejection fraction, and presence of unstable angina have estimated survivals not statistically less in any of these subsets than that of matched cohorts of the general population.
对1973年至1977年间布法罗医院连续进行的单纯冠状动脉搭桥手术病例进行的生命表分析显示,五年生存率估计为94%,与年龄和性别匹配的美国人群相当。根据性别、年龄、血管狭窄数量、移植节段数量、心肌梗死病史、射血分数和不稳定型心绞痛的存在情况对这些患者进行分组,这些亚组中的任何一组的估计生存率在统计学上都不低于普通人群的匹配队列。
