Comparison of Two-Year Outcomes in Patients Undergoing Isolated Coronary Artery Bypass Grafting With and Without Peripheral Artery Disease

We aimed to evaluate the long-term clinical outcomes among patients with peripheral arterial disease (PAD) after coronary artery bypass grafting. We studied 589 consecutive patients who had undergone isolated coronary artery bypass grafting from January 2003 to June 2005 at our university hospital. The effect of PAD was assessed by comparing the 2-year follow-up data from 2 groups of patients: 243 patients with and 346 without PAD. A large systematic atherosclerosis screening was performed, including cerebrovascular disease, lower extremity artery disease, and abdominal aorta disease and its branches. PAD was defined as a history of treated atherosclerotic disease and significant atherosclerotic stenosis on screening. Patients with PAD were significantly older (70 ± 9 vs 64 ± 11 years, p
