摘要: To evaluate the relative long-term improvement in coronary artery hemodynamics after revascularization by bypass graft surgery (CABG) or percutaneous transluminal angioplasty (PTCA), regional flow reserve (CFR) was measured, digital computer analysis of 35 mm cine film, 50 men undergoing cardiac catheterization. CFR (mean +/- SEM) 12 atherosclerotic arteries before 1.02 0.05. Mean 29 normal with arteriograms significantly higher (2.59 0.11) than that 16 patients revascularized CABG (2.02 0.17, p less .01) 14 those PTCA (1.97 0.12, .01). No difference between and groups found variables known to influence were similar groups. Equivalent significant is provided PTCA. We postula...
