Benign Prostatic Hyperplasia and Incident Cardiovascular Disease.

ABSTRACT

BACKGROUND: Data regarding the relationship between benign prostatic hyperplasia (BPH) and incident cardiovascular disease (CVD) are scarce. We aimed to clarify the association of BPH with the risk of developing CVD using a nationwide epidemiological database.Methods and Results: This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2022, including 2,370,986 men (median age 44 years). The primary endpoints were myocardial infarction (MI), angina pectoris (AP), stroke, heart failure (HF), and atrial fibrillation (AF), which were assessed separately. BPH was observed in 48,651 (2.1%) men. During a mean (±SD) follow-up of 1,359±1,020 days, 7,638 MI, 52,167 AP, 25,355 stroke, 58,183 HF, and 16,693 AF events were detected. Hazard ratios of BPH for MI, AP, stroke, HF, and AF were 1.04 (95% confidence interval [CI] 0.92-1.18), 1.31 (95% CI 1.25-1.37), 1.26 (95% CI 1.18-1.33), 1.21 (95% CI 1.16-1.27), and 1.15 (95% CI 1.07-1.24), respectively. We confirmed the robustness of our primary findings through a multitude of sensitivity analyses. In particular, a history of BPH was associated with a higher risk of developing CVD, even in participants without obesity, hypertension, diabetes, or dyslipidemia. CONCLUSIONS: Our analysis of a nationwide epidemiological dataset demonstrated that BPH was associated with a greater risk of developing CVD in middle-aged men.
