Background: Coronary artery disease (CAD) and atrial fibrillation (AF) often coexist, but the impact of clinical phenotypes of CAD on outcomes in AF patients in the non-vitamin K antagonist oral anticoagulant drugs (NOACs) era is less well understood. Methods: This was a post-hoc of the GLORIA-AF registry, a global, multicenter, prospective AF registry study. Patients were divided into three groups: prior history of myocardial infarction (MI)/unstable angina group (Group 1); stable angina group (Group 2); and a control group without stable angina or history of MI/unstable angina. The primary endpoint was the composite of all-cause death or stroke, and the safety endpoint was major bleeding. Results: A total of 24,827 patients were included in this analysis (median age was 71 (IQR, 64-78) years; 55% male) and 5394 (21.7%) had CAD. During a follow-up of 2 years, the incidence of the primary endpoint was 5.99 (95% CI, 5.33, 6.71) per 100 patient-years in Group 1, 4.04 (95% CI, 3.55, 4...Show moreBackground: Coronary artery disease (CAD) and atrial fibrillation (AF) often coexist, but the impact of clinical phenotypes of CAD on outcomes in AF patients in the non-vitamin K antagonist oral anticoagulant drugs (NOACs) era is less well understood.

During a follow-up of 2 years, the incidence of the primary endpoint was 5.99 (95% CI, 5.33, 6.71) per 100 patient-years in Group 1, 4.04 (95% CI, 3.55, 4.70) per 100 patient-years in Group 2, and 2.79 (95% CI, 2.62, 2.96) per 100 patient-years in the control group (p < .001). Compared the control group, the adjusted hazard ratio of the primary composite endpoint in Groups 1 and 2 were 1.58 (95% CI, 1.37, 1.83, p < .001) and 1.22 (95% CI, 1.04, 1.43, p = .012), respectively. Among anticoagulated patients with AF and CAD, NOACs were associated with a reduced risk of the primary composite endpoint and major bleeding, compared with vitamin K antagonists (VKA). Conclusions: CAD was prevalent in patients with AF, and clinical phenotypes of CAD influenced outcomes in patients with AF, with a history of MI/unstable angina being associated with a significantly increased risk of CV events, compared to stable angina. NOACs were superior to VKA in terms of the effectiveness and safety outcomes in patients with AF and concomitant CAD.Show less
