Different procedures for evaluation of left ventricular hypertrophy in overweight hypertensive adolescents

Abstract

Studies of arterial hypertension in adults could identify factors aggravating its course and increasing the risk of poor outcomes as myocardial infarction, stroke, etc. Myocardial hypertrophy is a major marker for disease severity in children. It may be underestimated in certain situations, in obesity in particular. This investigation analyzed the impact of the most common myocardial mass (MM) indices on the detection rate of myocardial hypertrophy in hypertensive adolescents: 1) ММ/Height2,7 (>45 g/m2,7); 2) ММ/Height2,7(>48 g/ m2,7), 3) MM/Height2,7 (>51 g/m2,7); 4) zMM(F) (>1,65); 5) ММ/BSA(>115 g/m2); 6) MM/Body weight (>3,0 g/kg). The findings depended on the used index and varied from 11,3 to 35,9%. The myocardial mass correlated with systolic blood pressure and exercise time. Hypertrophy was frequently encountered in persistent hypertension (28,6%; p<0,05) and obesity (p<0,05). ММ/Height2,7(>48 g/m2,7) and zMM(F) (>1,65) are the most adequate indices for the detection of myocardial hypertrophy in these patients
