Medical and surgical survival in Coronary artery disease in the 1980s

The survival of 1,657 patients with angiographically proved Coronary artery disease (CAD) was studied for 4 years (mean 2.0 ± 1.2) during the 1980s to examine the prognostic importance of multiple clinical variables. One hundred of the 1,049 medically treated patients (9.5%) and 31 of the 608 surgically treated patients (5.1%) died.
