0248: Echocardiographic profile of the Congolese hypertensive patients
2016
Objectives to assess echocardiographic aspect of Congolese hypertensive patients, and to identify predictive factors of left ventricular hypertrophy (LVH). Material and Methods A transversal study was lead in Brazzaville from January 2011 to December 2013 (36 months). 1125 hypertensive patients under treatment underwent transthoracic echocardiography. The test was carried out either as part of an initial assessment of the hypertension disease or during the development of evocative symptom or complication. Patients’ sociodemographic data and echocardiographic parameters were collected and analyzed. Results There were 621 males (55.2%) and 504 females (44.8%), mean age 54.7±12 years. The main indication of the test were the hypertension initial evaluation in 792 cases (70.4%), dyspnea in 122 cases (10.8%), investigation of ischemic stroke in 101 cases (9%), cardiac failure and chest pain in respectively 58 and 52 cases. The mean duration of hypertension status was 5.3±4.7 years. Echocardiographic test was abnormal in 590 cases (52.4%) and showed hypertrophic cardiomyopathy in 510 cases (45.2%), dilated and hypertrophic cardiomyopathy in 46 cases (4.1%), dilated cardiomyopathy with systolic dys-function in 31 cases (2.8%), coronary artery disease in 4 cases (0.4%). LVH was concentric in 470 cases (84.6%), eccentric in 70 cases (12.6%), and in 16 cases (3%), it was a concentric left ventricular remodeling. The left ventricular’s systolic ejection fraction average was 70.5±9.3%, relaxation disorders in 480 cases (42.6%). Age, male gender, income, known duration of hypertension and treatment were predictive factors of LVH. Conclusions echocardiographic profile of the Congolese hypertensive is quite various, left ventricular hypertrophy is the most predominant abnormality. Efficient management on the hypertension will lead to reduce its morbidity and mortality.
