Abstract

Background: We investigated the effects of coronary artery disease (CAD) or peripheral artery disease (PAD) on clinical outcomes of patients with abdominal aortic aneurysm (AAA) treated with endovascular aortic aneurysm repair (EVAR). Methods: We retrospectively evaluated a total of 475 patients with AAA treated with EVAR at a single center. Patients were divided into three groups: group A (n = 166), patients without CAD or PAD; group B (n = 196), patients with CAD but without PAD; and group C (n = 113), patients with PAD regardless of CAD. The primary endpoint was the accumulated rate of major adverse cardiovascular and cerebrovascular event (MACCE), a composite of all-cause death, myocardial infarction (MI), or stroke. Results: The prevalence of CAD and PAD in patients with AAA was 55.8 and 23.8%, respectively. Patients were followed for 40.2 ± 35.3 months. Baseline characteristics were similar among the groups except for current smoking (A, 27.4%; B, 20.8%; C, 50.5%; p = 0.001). Three years after EVAR, the incidences of MACCE (A, 5.6%; B, 9.5%; C, 16.7%; p = 0.021) and stroke (A, 0%; B, 2.2%; C, 5.2%; p = 0.025) were highest in group C. All-cause death and aneurysm death did not differ among the groups. PAD [hazard ratio (HR) 2.88, 95% confidence interval (CI) 1.32–6.29, p = 0.008] and previous stroke (HR 4.39, 95% CI 1.94–9.93, p < 0.001) were independent predictors of MACCE. Conclusions: PAD was an independent risk factor of increased MACCE and stroke for patients with AAA undergoing EVAR. More intensive secondary prevention may be needed to reduce adverse cardiovascular events in AAA patients with PAD.
