- Abstract
- Although atrial fibrillation (AF) is a well-established risk factor for ischemic stroke (IS) in hypertrophic cardiomyopathy (HCM), the risk of IS in HCM patients without documented AF is less recognized. This nationwide population-based cohort study using Korean National Health Insurance database included 8,328 HCM patients without documented AF and 1:2 propensity score-matched 16,656 non-HCM controls between 2010 and 2016. The primary outcome was an incident IS. During a mean follow-up of 6.1 years, IS occurred in 328/8,328 (3.9%) patients with HCM and 443/16,656 (2.7%) controls. The overall incidence of IS was 0.72/100 person-years in the HCM group, which was significantly higher than that in the control group (0.44/100 person-years) (HR 1.64; 95% CI 1.424-1.895; P < 0.001). The overall incidence of IS was 1.36/100 person-years in HCM patients aged >= 65 and 2.32/100 person-years years in those with heart failure, respectively. In the HCM group, age >= 65 years (adjusted HR 2.74; 95% CI 2.156-3.486; P < 0.001) and chronic heart failure (adjusted HR 1.75; 95% CI 1.101-2.745; P = 0.018) were independent risk factors for IS. HCM patients without documented AF are at a greater risk of IS, especially in those 65 years of age or older or those with chronic heart failure.
