The risk of coronary bypass surgery for patients with postinfarction angina.

abstract：:Of 1,801 patients in the 1985-1986 Percutaneous Transluminal Coronary Angioplasty (PTCA) Registry, 122 (6.8%) had periprocedural occlusion (4.9% in the catheterization laboratory, 1.9% outside the laboratory). Baseline patient factors independently associated with increased occlusion rates included triple-vessel disea...
