title: Usefulness of noncoronary vascular disease in predicting adverse events in the year following percutaneous coronary intervention.
abstract: It is unknown whether noncoronary vascular disease is associated with persistent cardiac risk in patients who undergo percutaneous coronary intervention (PCI). Using the National Heart, Lung, and Blood Institute Dynamic Registry, the incidence of death, myocardial infarction (MI), and repeat revascularization outcomes were compared in patients who had noncoronary vascular disease (n = 554) with patients who did not (n = 4,075). Vascular disease was defined as a history of stroke, transient ischemic attack, claudication, vascular bypass, limb amputation, or aortic aneurysm. Patients who had concomitant noncoronary vascular disease had more significant co-morbidities. Angiographic success rate was lower in patients who had concomitant noncoronary vascular disease (89.5% vs 93.2%, p <0.01), whereas in-hospital adverse events, including death (2.7% vs 1.3%, p <0.05), MI (4.7% vs 2.6%, p <0.01), stroke (1.1% vs 0.2%, p <0.001), major entry site complication (6.7% vs 3.5%, p <0.001), and need for coronary artery bypass grafting (2.2% vs 1.1%, p <0.05) were significantly higher. One-year death rate (10.5% vs 4.5%, p <0.001) and MI rate (9.2% vs 5.2%, p <0.001) were also significantly higher in patients who had vascular disease. After adjustment, vascular disease was independently associated with a higher risk of death or MI (risk ratio 1.4, 95% confidence interval 1.1 to 1.8) and death, MI, or coronary artery bypass grafting (risk ratio 1.3, 95% confidence interval 1.1 to 1.6) at 1 year. Repeat PCI rates were similar (15.9% vs 13.8%, p = NS). In conclusion, the presence of noncoronary vascular disease is an independent predictor of MI and death or MI 1 year after PCI. Because PCI is often performed before vascular surgery, these data may lend insight to the risk/benefit ratio of such an approach.
