Aspirin for primary prevention in patients with high cardiovascular risk: insights from CORE-Thailand registry.

ABSTRACT: Aspirin may be considered for primary prevention in non-elderly patients with high cardiovascular risk. However, contemporary management aimed at aggressive cardiovascular risk factor control may alter benefit-risk ratio of aspirin. Therefore, we aimed to examine the effect of aspirin for primary prevention on the long-term MACEs in a large cohort registry. Cohort Of patients with high Risk for cardiovascular Events (CORE-Thailand) registry is a prospective, multicenter, observational, longitudinal study of Thai patients with high atherosclerotic risk. Patients with established atherosclerotic cardiovascular diseases were excluded. Among 4259 patients with multiple cardiovascular risk factors, 1945 (45.7%) patients used aspirin. After propensity score matching, there were 3228 patients remained in post-matching analysis. During the median follow-up period of 58.2 months, we demonstrated that aspirin use increased risk of long-term MACEs in pre-matching cohort (unadjusted HR 1.76, 95% CI 1.43-2.17, P < 0.001) and post-matching cohort (HR 1.66 (1.31-2.10), P < 0.001). In addition, patients taking aspirin had a higher risk of bleeding than non-aspirin users in pre-matching cohort (unadjusted HR 2.28, 95% CI 1.09-4.75, P = 0.028). We demonstrated that aspirin was associated with increased risk of long-term MACEs in patients with multiple cardiovascular risk factors. Due to the non-randomized design, our results should be interpreted with caution.

Project description:BackgroundThe role of aspirin in reducing lipoprotein(a)-mediated atherothrombotic events in primary prevention is not established.ObjectivesThis study sought to assess whether low-dose aspirin benefits individuals with elevated plasma lipoprotein(a)-associated genotypes in the setting of primary prevention.MethodsThe study analyzed 12,815 genotyped individuals ≥70 years of age of European ancestry and without prior cardiovascular disease events enrolled in the ASPREE (ASPirin in Reducing Events in the Elderly) randomized controlled trial of 100 mg/d aspirin. We defined lipoprotein(a)-associated genotypes using rs3798220-C carrier status and quintiles of a lipoprotein(a) genomic risk score (LPA-GRS). We tested for interaction between genotypes and aspirin allocation in Cox proportional hazards models for incidence of major adverse cardiovascular events (MACE) and clinically significant bleeding. We also examined associations in the aspirin and placebo arms of the trial separately.ResultsDuring a median 4.7 years (IQR: 3.6-5.7 years) of follow-up, 435 MACE occurred, with an interaction observed between rs3798220-C and aspirin allocation (P = 0.049). rs3798220-C carrier status was associated with increased MACE risk in the placebo group (HR: 1.90; 95% CI: 1.11-3.24) but not in the aspirin group (HR: 0.54; 95% CI: 0.17-1.70). High LPA-GRS (vs low) was associated with increased MACE risk in the placebo group (HR: 1.70; 95% CI: 1.14-2.55), with risk attenuated in the aspirin group (HR: 1.41; 95% CI: 0.90-2.23), but the interaction was not statistically significant. In all participants, aspirin reduced MACE by 1.7 events per 1,000 person-years and increased clinically significant bleeding by 1.7 events per 1,000 person-years. However, in the rs3798220-C and high LPA-GRS subgroups, aspirin reduced MACE by 11.4 and 3.3 events per 1,000 person-years respectively, without significantly increased bleeding risk.ConclusionsAspirin may benefit older individuals with elevated lipoprotein(a) genotypes in primary prevention.

Project description:BackgroundThe Million Hearts Cardiovascular Disease Risk Reduction Model provides financial incentives for practices to lower 10-year atherosclerotic cardiovascular disease (ASCVD) risk for high-risk (ASCVD ≥30%) Medicare patients. To estimate average practice-level ASCVD risk reduction, we applied optimal trial outcomes to a real-world population with high ASCVD risk.MethodsThis study uses observational registry data from the National Cardiovascular Data Registry Practice Innovation and Clinical Excellence Registry from January 2013 to June 2016. We modeled ASCVD risk reductions using historical clinical trial data (reducing cholesterol by 26.5%, reducing systolic blood pressure by 10.9%, reducing smoking rates by 21.8%) the average reduction in ASCVD risk associated with individual and combined risk factor modifications, and then percentage of practices achieving the various incentive thresholds for the Million Hearts Model.ResultsThe final study population included 135 166 patients, with 16 248 (12.0%) with 10-year ASCVD risk of ≥30%, but without existing ASCVD. The mean 10-year ASCVD risk was 41.9% (±1 SD of 11.6). Using risk factor reductions from clinical trials, lowering cholesterol, blood pressure, and smoking rates reduced 10-year ASCVD risk by 3.3% (±3.1), 6.3% (±1.1) and 0.5% (±1.3), respectively. Combining all 3 reductions resulted in a 9.7% (±3.6) reduction, with 67 (27.0%) of practices achieving a patient-level average 10-year ASCVD risk reduction of ≥10%, 181 (73.0%) achieving a 2 to 10% reduction, and no practice achieving <2% reduction.ConclusionsIn cardiology practices, about 1 out of 8 patients have a 10-year ASCVD risk ≥30% and qualify as high risk in the Million Hearts Model. If practices target the three main modifiable risk factors and achieve reductions similar to clinical trial results, ASCVD risk could be substantially lowered and all practices could receive incentive payments. These findings support the potential benefit of the Million Hearts Model and provide guidance to participating practices.
