Studies on the impact of hypertension (HTN) on the outcome of patients with atrial fibrillation (AF) in the Middle East are scarce. The aim of this contemporary multicenter study is to evaluate the effect of the coexisting HTN on the baseline clinical profiles and 1-year prognosis in a cohort of Middle Eastern patients with AF. Consecutive AF patients in 29 hospitals and cardiology clinics were enrolled in the Jordan AF study (May 2019-December 2020). Patients were prospectively followed up for 1 year, and the study had no influence on their treatment, which was at the discretion of the treating physician. We compared clinical features, use of medications, and 1-year prognosis in patients with AF/HTN compared with AF/no HTN. Among 1849 non-valvular AF patients, 76.4% had HTN, with higher prevalence of diabetes, dyslipidemia, coronary heart disease, stroke, and left ventricular hypertrophy in HTN patients. There was a higher thromboembolic and bleeding risk among HTN patients. At 1 year, HTN patients had significantly higher rates of stroke and systemic embolism (SSE) (4.5%), acute coronary syndrome (ACS) (2.4%), rehospitalization (27.9%), and major bleeding events (3.0%) compared with non-HTN patients. In this cohort, the coexistence of HTN was associated with worse baseline clinical profile and 1-year outcomes.
