Étude de la géométrie ventriculaire gauche chez des hypertendus Noirs Africains

Abstract

AimTo determine the prevalence and determinants of different types of echocardiographic left ventricular remodeling in African black hypertensive patients. Patients and methodsA transversal descriptive study was conducted from January 1, 2015, to March 31, 2016, in the external explorations department of the Abidjan Heart Institute-Côte d'Ivoire. Transthoracic cardiac echo-graphs were performed in 524 (251 women) hypertensive subjects according to the American Society of Echocardiography convention. ResultsTwenty-nine percent of hypertensive patients had cardiac remodeling (in women and men, respectively, concentric remodeling 14.7 % and 15.7 %; concentric hypertrophy 6 % and 10.3 %; eccentric hypertrophy 7.6 % and 3.7 %). Only systolic and diastolic blood pressure levels were significantly correlated with left ventricular mass indexed to body surface area. ConclusionThis study showed a significant proportion of hypertensives with abnormal left ventricular geometry and confirmed the relationship between blood pressure level and left ventricular geometry change.
