title: Left ventricular geometry and white matter lesions in ischemic stroke patients.
abstract: Abnormal left ventricular (LV) geometry is associated with extracardiac organ damage in patients with hypertension. The aim of this study was to determine the relationship between LV geometry and white matter lesions (WMLs) in ischemic stroke patients. We retrospectively analyzed data from 155 patients (median age 62; 49.8% male) with mild ischemic stroke (median National Institutes of Health Stroke Scale score 4) who underwent brain magnetic resonance imaging and echocardiography. Patients were categorized into four groups: normal LV geometry, concentric remodeling, eccentric left ventricular hypertrophy (LVH) and concentric LVH. WMLs were graded using the Fazekas scale on fluid-attenuated inversion recovery images. Extensive WMLs were defined as a Fazekas score > 2. Extensive WMLs were more prevalent in patients with concentric LVH, eccentric LVH and concentric remodeling than in those with normal LV geometry. After adjusting for hypertension, age, diabetes mellitus, hypercholesterolemia, glomerular filtration rate and ischemic heart disease, patients with concentric remodeling [odds ratio (OR) 3.94, 95% confidence interval (CI) 1.26-12.31, p = 0.02] and those with concentric LVH (OR 3.69, 95% CI 1.24-10.95, p = 0.02), but not patients with eccentric LVH (OR 2.44, 95% CI 0.72-8.29, p = 0.15), had higher risk of extensive WMLs than patients with normal LV geometry.
