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.

Background:Acute myocardial infarction (AMI) patients with low body mass index (BMI) exhibit worse clinical outcomes than obese patients; however, to our knowledge, no prospective, nationwide study has assessed the effect of BMI on the clinical outcomes of AMI patients.Methods and Results:In this multi-center, prospective, nationwide Japanese trial, 2,373 AMI patients who underwent emergent percutaneous coronary intervention within 12 h of onset from the Japanese AMI Registry (JAMIR) were identified. Patients were divided into the following 4 groups based on their BMI at admission: Q1 group (BMI <18.5 kg/m2, n=133), Q2 group (18.5≤BMI<25.0 kg/m2, n=1,424), Q3 group (25.0≤BMI<30.0 kg/m2, n=672), and Q4 group (30.0 kg/m2≤BMI, n=144). The primary endpoint was all-cause death, and the secondary endpoint was a composite of cardiovascular death, non-fatal myocardial infarction (MI), and non-fatal stroke. The median follow-up period was 358 days. Q1 patients were older and had lower prevalence of coronary risk factors. Q1 patients also had higher all-cause mortality and higher incidence of secondary endpoints than normal-weight or obese AMI patients. Multivariate analysis showed that low BMI (Q1 group) was an independent predictor for primary endpoint.Conclusions:AMI patients with low BMI had fewer coronary risk factors but worse clinical outcomes than normal-weight or obese patients.

Background:Antiplatelet therapy is the corner stone of treatment following acute myocardial infarction (AMI). Prasugrel, a new and potent antiplatelet agent, was recently introduced to clinical practice. We compared the clinical outcomes of patients with AMI treated with prasugrel with those treated with clopidogrel in real-world clinical practice in Japan.Methods and Results:The Japan AMI Registry (JAMIR) is a multicenter, nationwide, prospective registry enrolling patients with AMI from 50 institutes. Between December 2015 and May 2017, a total of 3,411 patients were enrolled. Among them, 3,069 patients were treated with either prasugrel (n=2,607) or clopidogrel (n=462) during hospitalization. Median follow-up period was 12 months. Prasugrel-treated patients were predominantly male, younger, more often showed ST-elevation AMI, and had fewer comorbidities. After adjustment using inverse probability of treatment weighting, the primary endpoint, defined as a composite of cardiovascular death, non-fatal MI and non-fatal stroke, was comparable between the prasugrel and clopidogrel groups (adjusted hazard ratio [HR] 1.07, 95% confidence interval [CI] 0.67–1.72), whereas the risk of major bleeding (BARC type 3 or 5 bleeding) was significantly lower in the prasugrel group (adjusted HR 0.62, 95% CI 0.39–0.99).Conclusions:The present real-world database of the JAMIR demonstrated that the potent P2Y12-inhibitor prasugrel showed comparable rates of 1-year ischemic events to clopidogrel, but the risk of bleeding was lower with prasugrel than with clopidogrel.
