Risks of Recurrent Cardiovascular Events and Mortality in 1-Year Survivors of Acute Myocardial Infarction Implanted with Newer-Generation Drug-Eluting Stents.

ABSTRACT: Current treatments for acute myocardial infarction (AMI) have dramatically improved clinical outcomes during the first year after AMI. Less is known, however, about the subsequent risks of recurrent cardiovascular events and mortality in patients who survive 1 year after AMI. The purpose of the present study is to evaluate long-term clinical outcomes in 1-year AMI survivors who were implanted with newer-generation drug-eluting stents (DESs) since 2010. The COREA-AMI (CardiOvascular Risk and idEntificAtion of potential high-risk population in AMI) registry consecutively enrolled AMI patients who underwent percutaneous coronary intervention (PCI), and patients who received newer-generation DESs since 2010 were analyzed. The primary endpoint was major adverse cardiovascular events (MACEs), and secondary endpoint was all-cause mortality. Of 6242 AMI patients, 5397 were alive 1 year after the index procedure. The cumulative incidence of MACEs and all-cause death 1 to 7 years after AMI were 28.4% (annually 4-6%) and 20.2% (annually 3-4%), respectively. Multivariate analysis showed that uncontrolled systolic blood pressure (SBP) and serum low-density lipoprotein cholesterol (LDL-C) concentration, as well as traditional risk factors, were associated with MACEs and all-cause death. Recurrent non-fatal myocardial infarction, ischemic stroke, and bleeding events within 1 year were significantly associated with all-cause death. The risks of adverse cardiovascular events and death remain high in AMI patients more than 1 year after the index PCI with newer-generation DESs. Traditional risk factors, uncontrolled SBP and LDL-C, and non-fatal adverse events within 1 year after the index procedure strongly influence long-term clinical outcomes.

Project description:BackgroundComparative studies regarding the long-term clinical outcomes of statin intensity between acute myocardial infarction (AMI) patients with prediabetes and those with type 2 diabetes mellitus (T2DM), after successful implantation of newer-generation drug-eluting stents (DES) with statin treatment, are limited. We compared the 2-year clinical outcomes between these patients.MethodsA total of 11,612 AMI patients were classified as statin users (n = 9893) and non-users (n = 1719). Thereafter, statin users were further divided into high-intensity (n = 2984) or low-moderate-intensity statin (n = 6909) treatment groups. Those in these two groups were further classified into patients with normoglycemia, prediabetes, and T2DM. The major outcomes were the occurrence of major adverse cardiac events (MACE), defined as all-cause death, recurrent myocardial infarction (Re-MI), or any repeat coronary revascularization.ResultsAfter adjusting for both high-intensity and low-moderate-intensity statin users, the cumulative incidences of MACE (p = 0.737, p = 0.062, respectively), all-cause death, Re-MI, and any repeat revascularization were similar between the prediabetes and T2DM groups. In the total study population, both high-intensity and low-moderate-intensity statin treatments showed comparable results. However, in the patients who enrolled after October 2012, the cumulative incidences of MACE (aHR 1.533; 95% CI 1.144-2.053; p = 0.004) and any repeat revascularization (aHR, 1.587; 95% CI 1.026-2.456; p = 0.038) were significantly lower in high-intensity statin users than in low-moderate intensity statin users. The beneficial effects of high-intensity compared to low-moderate-intensity statin therapy were more apparent in the normoglycemia group than hyperglycemia group, as it reduced the cumulative incidences of MACE (aHR 1.903; 95% CI 1.203-3.010; p = 0.006) and any repeat revascularization (aHR 3.248; 95% CI 1.539-6.854; p = 0.002).ConclusionsIn this retrospective registry study, prediabetes and T2DM groups showed comparable clinical outcomes, after administering both high-intensity and low-moderate-intensity statin treatments. However, these results are likely to be clearly proved by further studies, especially in patients with AMI who are being treated in contemporary practice.Trial registrationRetrospectively registered.

Project description:ImportanceWomen with acute myocardial infarction (MI) undergoing mechanical reperfusion remain at increased risk of adverse cardiac events and mortality compared with their male counterparts. Whether the benefits of new-generation drug-eluting stents (DES) are preserved in women with acute MI remains unclear.ObjectiveTo investigate the long-term safety and efficacy of new-generation DES vs early-generation DES in women with acute MI.Design, setting, and participantsCollaborative, international, individual patient-level data of women enrolled in 26 randomized clinical trials of DES were analyzed between July and December 2016. Only women presenting with an acute coronary syndrome were included. Study population was categorized according to presentation with unstable angina (UA) vs acute MI. Acute MI included non-ST-segment elevation MI (NSTEMI) or ST-segment elevation MI (STEMI).InterventionsRandomization to early- (sirolimus- or paclitaxel-eluting stents) vs new-generation (everolimus-, zotarolimus-, or biolimus-eluting stents) DES.Main outcomes and measuresComposite of death, MI or target lesion revascularization, and definite or probable stent thrombosis at 3-year follow-up.ResultsOverall, the mean age of participants was 66.8 years. Of 11?577 women included in the pooled data set, 4373 (37.8%) had an acute coronary syndrome as clinical presentation. Of these 4373 women, 2176 (49.8%) presented with an acute MI. In women with acute MI, new-generation DES were associated with lower risk of death, MI or target lesion revascularization (14.9% vs 18.4%; absolute risk difference, -3.5%; number needed to treat [NNT], 29; adjusted hazard ratio, 0.78; 95% CI, 0.61-0.99), and definite or probable stent thrombosis (1.4% vs 4.0%; absolute risk difference, -2.6%; NNT, 46; adjusted hazard ratio, 0.36; 95% CI, 0.19-0.69) without evidence of interaction for both end points compared with women without acute MI (P for interaction?=?.59 and P for interaction?=?.31, respectively). A graded absolute benefit with use of new-generation DES was observed in the transition from UA, to NSTEMI, and to STEMI (for death, MI, or target lesion revascularization: UA, -0.5% [NNT, 222]; NSTEMI, -3.1% [NNT, 33]; STEMI, -4.0% [NNT, 25] and for definite or probable ST: UA, -0.4% [NNT, 278]; NSTEMI, -2.2% [NNT, 46]; STEMI, -4.0% [NNT, 25]).Conclusions and relevanceNew-generation DES are associated with consistent and durable benefits over 3 years in women presenting with acute MI. The magnitude of these benefits appeared to be greater per increase in severity of acute coronary syndrome.

Project description:Background Percutaneous coronary intervention of calcified lesions was associated with worse outcomes in the era of bare-metal and first-generation drug-eluting stents. Data on percutaneous coronary intervention of calcified lesions with newer-generation drug-eluting stents are scarce. Therefore, we investigated the impact of lesion calcification on clinical outcomes in patients undergoing percutaneous coronary intervention with a bioresorbable-polymer sirolimus-eluting stent or a durable-polymer everolimus-eluting stent. Methods and Results Patients (n=2361) from BIOFLOW II, IV, and V trials were categorized into moderate/severe versus none/mild lesion calcification by a core laboratory. End points were target-lesion failure (TLF) (cardiac death, target-vessel myocardial infarction, or target-lesion revascularization) and probable/definite stent thrombosis at 2 years. The agreement in calcification assessment between the operator and the core laboratory was weak (weighted κ, 0.23). Patients with moderate/severe calcification (n=303; 16%) had higher TLF (13.5% versus 8.4%; P=0.003) and stent thrombosis rates (2.1% versus 0.2%; P<0.0001), whereas target-lesion revascularization was not different between the groups (5.0% versus 3.9%; P=0.302). After adjustment, calcification did not emerge as an independent predictor of TLF (adjusted hazard ratio [aHR], 1.37; 95% CI, 0.89-2.08; P=0.148) but did for target-vessel myocardial infarction (aHR, 1.66; 95% CI, 1.03-2.68; P=0.037). TLF rates were similar between bioresorbable-polymer sirolimus-eluting stent and durable-polymer everolimus-eluting stent (12.6% versus 15.4%, P=0.482) in moderate/severe calcification. In none/mild calcification, the bioresorbable-polymer sirolimus-eluting stent showed lower TLF (7.5% versus 10.3%, P=0.045). Conclusions With newer-generation drug-eluting stents, moderate/severe lesion calcification was not associated with more TLF after adjustment for the higher risk of patients with coronary calcification, whereas the rate of target-vessel myocardial infarction was higher. The bioresorbable-polymer sirolimus-eluting stent and durable-polymer everolimus-eluting stent were equally effective and safe in calcified lesions.
