Abstract:
:The aim of the present study was to determine the prevalence of Left ventricular hypertrophy (LVH) and different left ventricular (LV) geometric patterns in the middle-aged women population of Tallinn, to assess the relationship between LV geometry, age, blood pressure and LV repolarization duration and inhomogeneity. A random sample of the population, 482 women aged 35-59, was examined in the framework of a cardiovascular risk factors survey for the WHO/CINDI programme years 1999-2000. Patients with valvular pathology, primary cardiomyopathy, atrial fibrillation, bundle branch blocks and flat T wave on electrocardiography (ECG) were excluded; 398 (82.2%) of the participants underwent echocardiography (Echo) and standard 12-lead ECG at rest and were included in the study. LVH was defined if left ventricular mass (LVM), LVM/height and LVM/BSA were >198 g, >121 g/m and > 120 g/m2, respectively. Arterial hypertension was determined in 23.1% of the women. The prevalence of arterial hypertension was three times higher in those aged 50-59 than in those aged 40-49 (37.4% vs 13.2%; p < 0.05). Different geometric patterns were found as follows: concentric hypertrophy in 9.1%; eccentric hypertrophy 33.9%; concentric remodelling 9.5% and normal geometry 47.5% of the participants. Concentric hypertrophy was found exclusively in hypertensive women and increased with age. No age-related eccentric hypertrophy and concentric remodelling differences were found, either in the normotensive or in the hypertensive group. Prolonged QT dispersion--a marker of increased myocardial electrical instability, was associated with LVH and arterial hypertension and was related mostly to concentric hypertrophy in hypertensives.
