BACKGROUND: Patients infected with human immunodeficiency virus (HIV) are at increased risk of cardiovascular diseases. However, little is known regarding the risk of ischemic stroke in HIV-infected individuals with atrial fibrillation (AF).Methods and Results: From the Korean National Health Insurance Service (NHIS) database from January 1, 2005 to December 31, 2016, we analyzed 962,116 patients with prevalent non-valvular AF aged ≥18 years. The overall HIV prevalence in AF patients was 0.17% (1,678 of 962,116). Oral anticoagulant (OAC)-naïve non-valvular AF (NVAF) patients with HIV had increased risks of ischemic stroke/systemic embolism (SE) [adjusted hazard ratio (HR) 1.37; 95% confidence interval (CI), 1.21-1.54], and major bleeding (adjusted HR 1.29; 95% CI, 1.15-1.46), compared with those without HIV. The incidence of ischemic stroke/SE in NVAF patients with HIV without any risk factors was similar to that of those without HIV at intermediate risk (i.e., male CHA2DS2-VASc score of 1) (2.04 vs. 2.18 events per 100 person-years). However, the use of OACs in AF patients with HIV was suboptimal, being only 8.9% at the time of AF diagnosis and 31.8% throughout the study period. CONCLUSIONS: The risks of ischemic stroke/SE and major bleeding were significantly higher in HIV-infected patients compared with non-HIV-infected patients with AF. Despite this, the actual use of OACs among AF patients with HIV was suboptimal.
