ObjectivesClinical and electrocardiographic and echocardiographic data were collected in 50 black Africans with hypertension to study modifications in left ventricular geometry.MethodsThirty men and 20 women with hypertension (mean age 40.9 +/- 10.2 years) who had recently immigrated from Africa were included in the study. Parameters recorded were: systolic and diastolic pressures, body mass index (BMI = weight/height2); ECG; echocardiography (36 patients): end diastolic septal and posterior wall thickness, left ventricle diameter, left ventricle mass (LVM) and relative wall thickness.ResultsSystolic and diastolic pressures and BMI were 169 +/- 24 mmHg, 105 +/- 14 mmHg and 26.7 +/- 3.9 kg/m2). LVM was 129 +/- 41 g/m2 (Normal < 134 g/m2) in men and 113 +/- 35 g/m2 (Normal = 110 g/m2) in women. Concentric remodeling was found in 8 patients (LVM = normal, relative wall thickness > or = 0.45), concentric left ventricle hypertrophy in 10 (LVM > normal, relative wall thickness > or = 0.45), excentric left ventricular hypertrophy in 6 (LVM > normal, relative wall thickness < 0.45), asymmetric septal hypertrophy in 4 and normal echocardiogram in 8. There was a negative correlation between age and end diastolic left ventricle diameter (r = -0.34, p < 0.05) and age and end systolic ventricle diameter (r = -0.74, p < 0.05). There was a positive correlation between body surface and septal thickness (r = 0.34, p < 0.05), posterior wall thickness (r = 0.56, relative wall p < 0.001), and relative wall thickness (r = 0.45, p = 0.05).ConclusionThis population of young subjects with hypertension showed a high prevalence of modifications in left ventricular geometry with predominant concentric modeling with (8/36) and without (10/36) left ventricle hypertrophy.
