The aim of the study was to evaluate left ventricular systolic function and hemodynamic indices in different patterns of left ventricular hypertrophy and geometry in children with hypertensive disease.The study group consisted of 68 children (54 boys and 14 girls) with mild or moderate form of essential hypertension. The methods: Based on echocardiographic left ventricular mass index and relative wall thickness patients were classified into: normal geometry (15children), concentric remodeling (14children), concentric hypertrophy (16 children), and eccentric hypertrophy (23 children). Results: End-systolic,end-diastolic and stroke volumes were highest in eccentric hypertrophy and lowest in concentric remodeling. End-diastolic volume/body surface area (preload) was highest in eccentric hypertrophy and lowest in concentric remodeling. The highest values of end-systolic stress (afterload) were noted in normal geometry and the lowest ones in concentric remodeling. Total peripheral resistance was highest in concentric remodeling and lowest in eccentric hypertrophy. Conclusions: This study suggest that cardiac hypertrophy might develop in children with mild or moderate form of systemic hypertension. Children with four different patterns of left ventricular geometry differ notably in respect to hemodynamic.
