Vascular disease burden and in-hospital outcomes among patients undergoing percutaneous coronary intervention in New York State

The presence of atherosclerosis in extracardiac vascular beds is associated with an increased risk of adverse cardiovascular outcomes among stable patients with coronary artery disease (CAD). However, there is little data regarding the impact of the presence and extent of vascular disease on outcomes in patients with CAD undergoing percutaneous coronary intervention. We analyzed 69,045 consecutive patients from the New York State Coronary Angioplasty Reporting System database who underwent percutaneous coronary intervention between 1998 and 1999. Vascular disease burden was assessed by history of aortoiliac, femoral-popliteal, and carotid disease. Patients were stratified into 3 groups: CAD alone, CAD and 1 additional site, and CAD and 2 or 3 additional sites. A logistic regression model was constructed to determine the relation between vascular disease burden and in-hospital mortality. Any history of vascular disease was present in 5915 (8.6%) of the population, of whom 4840 (82%) had CAD and 1 other disease location and 1075 (18%) had CAD and 2 or 3 other disease locations. There was a significant relationship between the number of disease locations and hospital mortality, ranging from 0.7% in patients with CAD alone to 2.0% and 2.6% for patients with 1 or >or =2 disease locations, respectively (P
