Background: This post hoc subanalysis aimed to investigate the impact of polyvascular disease (PolyVD) in patients with acute myocardial infarction (AMI) in the contemporary era of percutaneous coronary intervention (PCI).

Methods and Results: The Japan Acute Myocardial Infarction Registry (JAMIR), a multicenter prospective registry, enrolled 3,411 patients with AMI between December 2015 and May 2017. Patients were classified according to complications of a prior stroke and/or peripheral artery disease into an AMI-only group (involvement of 1 vascular bed [1-bed group]; n=2,980), PolyVD with one of the complications (2-bed group; n=383), and PolyVD with both complications (3-bed group; n=48). The primary endpoint was all-cause death. Secondary endpoints were major adverse cardiovascular events (MACE), including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and major bleeding. In the 1-, 2-, and 3-bed groups, the cumulative incidence of all-cause death was 6.8%, 17.5%, and 23.7%, respectively (P<0.001); that of MACE was 7.4%, 16.4%, and 33.8% (P<0.001), respectively; and that of major bleeding was 4.8%, 10.0%, and 13.9% (P<0.001), respectively. PolyVD was independently associated with all-cause death (hazard ratio [HR] 2.21; 95% confidence interval [CI], 1.48–3.29), MACE (HR 2.07; 95% CI 1.40–3.07), and major bleeding (HR 1.68; 95% CI 1.04–2.71).

Conclusions: PolyVD was significantly associated with worse outcomes, including thrombotic and bleeding events, in the contemporary era of PCI in AMI patients.
