Does isolated coronary bypass surgery result in long-term survival comparable to the general population?
Patients undergoing isolated coronary bypass surgery demonstrate a 5-year survival rate comparable to the general population, a finding that holds true across various clinical and demographic subsets.
Absolute Event Rate: 94% vs 94%
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.
Greene et al. (Wed,) conducted a cohort in Coronary artery disease requiring bypass surgery. Isolated coronary bypass surgery vs. Age- and sex-matched US general population was evaluated on 5-year survival. Isolated coronary bypass surgery yielded an estimated 5-year survival of 94%, equal to that of an age- and sex-matched cohort of the US general population.
