Özet
Several epidemiologic studies have demonstrated that left ventricular hypertrophy (LVH) is an independent and important cardiovascular risk factor. In this study, we assessed the patterns of left ventricular geometry in patients with hypertensive hemorrhagic stroke. Methods: The spectrum of left ventricular geometric patterns was investigated in 62 patients with hypertensive hemorrhagic stroke and 49 patients with essential hypertension not complicated with cerebrovascular accident using two-dimensionally guided M-mode echocardiograms. Four different patterns of left ventricular geometry were identified by categorizing patients according to values of relative wall thickness (RWT) and left ventricular mass index (LVMI). Results: Of the 62 patients with hypertensive hemorrhagic stroke, 58% had increased RWT and LVMI (concentric hypertrophy), 22.6% had increased RWT with normal LVMI (concentric remodeling), 9.7% had increased LVMI with normal RWT (eccentric hypertrophy) and only in 9.7% both variables were normal. Patients with hypertensive hemorrhagic stroke showed higher values of LVMI, and increased prevalence of LVH and concentric LVH in comparison to patients with essential hypertension not complicated with cerebrovascular accident (143±55 g/m2 vs.116 ±38 g/m2, 67.7% vs. 38.8%, 58% vs 20.4%; p
Abstract
Several epidemiologic studies have demonstrated that left ventricular hypertrophy (LVH) is an independent and important cardiovascular risk factor.
