BACKGROUND: Physical activity is associated with a lower risk of major adverse cardiovascular events, but few individuals achieve guideline-recommended levels of physical activity. Strategies informed by behavioral economics increase physical activity, but their longer-term effectiveness is uncertain. We sought to determine the effect of behaviorally designed gamification, loss-framed financial incentives, or their combination on physical activity compared with attention control over 12-month intervention and 6-month postintervention follow-up periods. METHODS: Between May 2019 and January 2024, participants with clinical atherosclerotic cardiovascular disease or a 10-year risk of myocardial infarction, stroke, or cardiovascular death of ≥7.5% by the Pooled Cohort equation were enrolled in a pragmatic randomized clinical trial. Participants received a wearable device to track daily steps, established a baseline, selected a step goal increase, and were randomly assigned to control (n=151), behaviorally designed gamification (n=304), loss-framed financial incentives (n=302), or gamification+financial incentives (n=305). The primary outcome of the trial was the change in mean daily steps from baseline through the 12-month intervention period. RESULTS: A total of 1062 patients (mean±SD age, 67±8; 61% female; 31% non-White) were enrolled. Compared with control subjects, participants had significantly greater increases in mean daily steps from baseline during the 12-month intervention in the gamification arm (adjusted difference, 538.0 [95% CI, 186.2–889.9]; P =0.0027), financial incentives arm (adjusted difference, 491.8 [95% CI, 139.6–844.1]; P =0.0062), and gamification+financial incentives arm (adjusted difference, 868.0 [95% CI, 516.3–1219.7]; P <0.0001). During the 6-month follow-up, physical activity remained significantly greater in the gamification+financial incentives arm than in the control arm (adjusted difference, 576.2 [95% CI, 198.5–954]; P =0.0028), but it was not significantly greater in the gamification (adjusted difference, 459.8 [95% CI, 82.0–837.6]; P =0.0171) or financial incentives (adjusted difference, 327.9 [95% CI, −50.2 to 706]; P =0.09) arms after adjustment for multiple comparisons. CONCLUSIONS: Behaviorally designed gamification, loss-framed financial incentives, and the combination of both increased physical activity compared with control over a 12-month intervention period, with the largest effect in gamification+financial incentives. These interventions could be a useful component of strategies to reduce cardiovascular risk in high-risk patients. REGISTRATION: URL: https://clinicaltrials.gov; Unique Identifier: NCT03911141.

The RCTs of AF-PCI/ACS patients lack such information (Table 1).[[5], [7]] A subgroup analysis of the REDUAL PCI trial showed that only 9.9% of included patients had high-risk procedural factors and only 10% had both high-risk procedural and clinical complexity factors.[13] Although high-risk procedural features were not explicit exclusion criteria, the dearth of procedural details and the absence of statistically powered outcome stratification by PCI complexity prevent generalization of the four RCT results to PCI patients with high ischaemic risk PCI, which may represent up to 60% of cases according to a recent study.[12] Sub-analyses and specific high-risk subgroups. These patients made up only a fraction of the patients enrolled in WOEST (27%), PIONEER AF-PCI (29%), RE-DUAL (50%), AUGUSTUS (51%), and ENTRUST-AF PCI (52%), and individual trials were not powered to detect a treatment by subgroup interaction. The low thrombogenicity of new stent platforms, together with the increasing awareness of the prognostic impact of bleeding events have prompted the design of many RCTs testing a de-escalation or shortening of antithrombotic therapy, aiming at reducing bleeding without any trade-off in ischaemic events (Table 1).[38] Among them, the RCTs including patients with AF-PCI/ACS were the only ones in which: (i) the primary endpoints did not include ischaemic outcomes; (ii) procedural details were not reported; (iii) ACS patients were not well represented, as none focused entirely on the acute setting; (iv) "de-escalation" was started very early after PCI (Table 1).

The optimal antithrombotic regimen for patients with atrial fibrillation (AF) who had an acute coronary syndrome (ACS) or have undergone percutaneous coronary intervention (PCI) is not known. The authors sought to determine which antithrombotic regimen best balances safety and efficacy. AUGUSTUS, a multicenter 2 × 2 factorial design randomized trial compared apixaban with vitamin K antagonist (VKA) and aspirin with placebo in patients with AF with recent ACS and/or PCI treated with a P2Y 12 inhibitor. We conducted a 4-way analysis comparing safety and efficacy outcomes in the 4 randomized groups. The primary outcome was a composite of all-cause death, major or clinically relevant nonmajor bleeding, or hospitalization for cardiovascular causes over 6-month follow-up. Secondary outcomes included individual components of the primary endpoint. A total of 4,614 patients were enrolled. All patients were treated with a P2Y 12 inhibitor. The primary endpoint occurred in 21.9% of patients randomized to apixaban plus placebo, 27.3% randomized to apixaban plus aspirin, 28.0% randomized to VKA plus placebo, and 33.3% randomized to VKA plus aspirin. Rates of major or clinically relevant nonmajor bleeding and hospitalization for cardiovascular causes were lower with apixaban and placebo compared with the other 3 antithrombotic strategies. There was no difference between the 4 randomized groups with respect to all-cause death. In patients with AF and a recent ACS and/or PCI, an antithrombotic regimen that included a P2Y 12 inhibitor and apixaban without aspirin resulted in a lower incidence of the composite of death, bleeding, or cardiovascular hospitalization than regimens including VKA, aspirin, or both.

Background: Novel P2Y12 inhibitors prasugrel and ticagrelor were approved for patients with acute coronary syndrome (ACS) in 2009 and 2011, respectively. We assessed the association of racial, ethnic, and socioeconomic factors with initiation of and adherence to novel P2Y12 inhibitors in a commercially insured population., Methods: We performed a retrospective cohort analysis of adults undergoing percutaneous coronary intervention with placement of a drug-eluting stent, stratified by ACS status, between January 2008 and December 2016 using Clinformatics Data Mart (OptumInsight). We estimated multivariable logistic regression models to identify factors associated with the initiation of clopidogrel vs novel P2Y12 inhibitors as well as subsequent 6-month medication adherence, assessed via pharmacy records., Results: A total of 55,664 patients were included in the analysis. Hispanic ethnicity was independently associated with the initiation of clopidogrel compared with novel P2Y12 inhibitors among ACS patients (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.04-1.36; P<.01). ACS patients with an annual median household income of over $100,000 were less likely to be started on clopidogrel when compared with those who earned less than $40,000 (OR, 0.67; 95% CI, 0.61-0.75; P<.01). Black race, Hispanic ethnicity, and lower household income were each associated with significantly reduced odds of P2Y12 inhibitor adherence., Conclusion: Hispanic ethnicity and lower household income were associated with novel P2Y12 inhibitor initiation, and non-White race and ethnicity were associated with lower P2Y12 inhibitor adherence over 6-month follow-up. These findings highlight continued inequity of care, even in an insured population, and point to a need for new strategies to close these gaps.
