Background. - Peripheral vascular disease (PVD) is associated with a high risk of cardiovascular events after an acute coronary syndrome (ACS). The impact of suboptimal risk-factor control and drug prescription on morbidity and mortality rates in patients with PVD following an ACS remains to be established. Aims. - To assess whether a global atherosclerosis management programme and optimal secondary prevention could benefit high-risk PVD patients after an ACS. Methods. - A total of 851 ACS patients underwent an intensified intervention focusing on evaluating risk factors and atherosclerosis lesions, and on optimizing treatment and education. We compared its impact on long-term risk factors, medication observance and cardiovascular outcomes in patients with coronary artery disease (CAD) alone (n = 715, 84.0%) and with both CAD and PVD (n = 136). Results. - At a median follow-up of 18.6 months, both groups reached recommended secondary prevention goals and showed no significant differences in rates of drug prescription. PVD was not associated with minor cardiovascular events (hazard ratio [HR] 1.32, 95% confidence interval [CI] 0.57-3.02) but remained independently associated with major (HR 2.15, 95% CI 1.12-4.13) and total (HR 1.76, 95% CI 1.05-2.93) cardiovascular events. Compared to patients with CAD alone, this risk was significantly higher in CAD patients with both PVD and diabetes (HR 2.87, 95% CI 1.52-5.43), but not in PVD patients without diabetes (HR 1.35, 95% CI 0.71-2.56) or diabetic patients without PVD (HR 1.11, 95% CI 0.68-1.81). Conclusion. - Despite optimization of risk-factor control and drug prescription after ACS, patients with both PVD and diabetes carry a 2.9-fold higher risk of cardiovascular events at 18-month follow-up versus patients with CAD alone. This excess risk was not significant in PVD patients without diabetes or in diabetic patients without PVD. © 2010 Elsevier Masson SAS. All rights reserved.
