Vascular complications following coronary intervention correlate with long-term cardiac events.

We aimed to study the consequences and late outcomes of patients who experienced peripheral vascular complications (PVCs) following percutaneous coronary interventions (PCI). A retrospective analysis of the medical records of 10,669 patients who underwent PCI and experienced PVC between 1995 and 2002 was conducted. One thousand ninety-six patients (10.27% of the study cohort) had PVC post-PCI. After PCI, patients with PVC had higher rates of in-hospital complications (P < 0.001) when compared to patients without PVC, including Q-wave myocardial infarction (MI; 1.2% vs. 0.3%), coronary artery bypass grafting (CABG; 3.8% vs. 0.6%), and death (4.0% vs. 1.0%). At 1-year follow-up, late complications of MI (37.4% vs. 25.4%), non-Q-wave MI (34.9% vs. 22.7%), death (12.9% vs. 5.9%), and CABG (5.7% vs. 4.5%) were higher (< 0.001) in patients with PVC compared to those without. Multivariate analysis identified PVC as a significant predictor of 1-year mortality (P = 0.045). This study underscores the need to make diligent efforts to minimize PVC and follow up these patients for future coronary events. Copyright 2004 Wiley-Liss, Inc.
