Long-term prognostic implication of extracardiac vascular disease in patients undergoing percutaneous coronary intervention.

Patients with extracardiac vascular disease were identified from 2,372 consecutive percutaneous coronary intervention (PCI) cases performed between 1997 and 2001. After multivariate adjustment, we found the presence of extracardiac vascular disease to be associated with a significantly higher risk for late mortality (hazard ratio [HR] 1.4, 95% confidence interval [CI] 1.0 to 2.0, p = 0.029). When extracardiac vascular disease was separated into cerebrovascular disease and peripheral vascular disease, cerebrovascular disease was less common but was associated with a trend towards worse survival.
