Long-term survival of patients with coronary artery disease during the 1970s : a cohort study.
This study was undertaken to determine the effects of altered risk factors and treatment modalities on the short-and long-term survival of patients with documented coronary artery disease whose conditions were diagnosed from 1972 through 1982, Study design : The study was a retrospective database analysis of clinical, angiographic, and follow-up information.
Data from all patients referred for cardiac catheterization at the Baptist Memorial Hospital, Memphis, Tenn, were studied.
Risk factors and survival of patients who underwent cardiac catheterization from 1972 through 1982 and who were followed up for at least 5 years were evaluated.
Cohort A included 1,821 patients studied from 1972 through 1977 ; cohort B included 5,369 patients studied between 1977 and the end of 1982.
Each cohort was subdivided based on type of therapy (medical or surgical) that the patients received.
Measurements and results
The 30-day (short-term) and 5-year (long-term) survival rates were compared by life table methods.
Short-term survival improved significantly in both medical (from 94.9% to 97.5%, p<0.001) and surgical (from 95.5% to 97.6%, p<0.001) groups from cohort A to cohort B. Long-term survival, however, did not differ significantly between the two cohorts.
In the medical group, 5-year survival in cohort A was 86.3% and in cohort B it was 86.9% (p=NS) ; in the surgical group, in cohort A it was 89.1% while in cohort B it was 89.4% (p=NS).
