Article Description

Aims: The objective was to assess the association between angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) prescription at discharge in patients hospitalized for symptomatic lower extremity artery disease (LEAD) and 1-year mortality. Methods and results: The COPART registry is a multicentre, prospective, observational, cohort study which includes consecutive patients hospitalized for symptomatic LEAD in four French academic centres. All-cause mortality during a 1-year follow-up after hospital discharge was compared between patients with ARB, patients with ACEI and patients without ARB or ACEI. Analyses were performed using Cox models. As a sensitivity analysis, a propensity score (PS)-matching analysis was carried out. Among 1981 patients, 421 had ARB (21.3%), 766 ACEI (38.7%), and 794 no ACEI/ARB (40.1%) at discharge. During the 1-year follow-up, incidence rates for mortality were 12.6/100 person-years [95% confidence interval (CI) 9.7-16.1] for patients with ARB, 15.8/100 person-years (95% CI 13.4-18.6) for patients with ACEI and 19.8/100 person-years for patients without ACEI/ARB (95% CI 17.2-22.8). In a multivariate Cox model, ARB at discharge was associated with decreased mortality compared with no ACEI/ARB, hazard ratio (HR) 0.68 (95% CI 0.49-0.95), and with ACEI, HR 0.69 (95% CI 0.49-0.97). These results are consistent with those obtained by the Cox analyses in the PS-matched sample: HR 0.68 (95% CI 0.47-0.98) for patients with ARB compared with no ARB. Conclusion: Angiotensin receptor blockers at discharge after hospitalization for symptomatic LEAD is associated with a better survival compared with ACEI or no ACEI/ARB.
