Left ventricular hypertrophy evaluation in obese hypertensive patients: effect of left ventricular mass index criteria.

Abstract:

PURPOSE:To evaluate left ventricular mass (LVM) index in hypertensive and normotensive obese individuals. METHODS:Using M mode echocardiography, 544 essential hypertensive and 106 normotensive patients were evaluated, and LVM was indexed for body surface area (LVM/BSA) and for height2 (LVM/h2). The 2 indexes were then compared in both populations, in subgroups stratified according to body mass index (BMI): <27; 27-30; >/= 30kg/m2. RESULTS:The BSA index does not allow identification of significant differences between BMI subgroups. Indexing by height2 provides significantly increased values for high BMI subgroups in normotensive and hypertensive populations. CONCLUSION:Left ventricular hypertrophy (LVH) has been underestimated in the obese with the use of LVM/BSA because this index considers obesity as a physiological variable. Indexing by height2 allows differences between BMI subgroups to become apparent and seems to be more appropriate for detecting LVH in obese populations.
