Abstract
Background:Cardiovascular disease is a growing public health problem in Africa. The extent of heart disease in Cameroon remains largely unknown. This study aimed at reporting the etiology of cardiac disease in a cardiologic clinic situated in a semi-urban area in the West region of Cameroon.
Methods:This is an analysis of echocardiographic diagnosis of cardiac disease done between July 2008 and October 2010 at the“Centre Medical de la Trinité” in the West region of Cameroon. Data included age, sex and echocardiographic findings.
Results:A total of 1252 patients presented with abnormal echocardiograms, 60.4% (n = 756) being female and 85.8% (n = 1074) aged over 50 years. Overall, the most important conditions were hypertensive heart disease (41.5%, n = 520) and cardiomyopathies (30.5%, n = 382). Among patients aged less than 10 years, congenital heart diseases were the most frequent (52.4%, n = 22), and rheumatic heart disease was the most important cardiac condition in patients aged 10 to 19 years (62.1%, n = 18) and those aged 20 to 39 years (53.3%, n = 8). Congenital heart diseases included persistent ductus arteriosus (27.6%, n = 8), tetralogy of Fallot (20.7%, n = 6) and inter-atria /interventricular communication (20.7%, n = 6).
Conclusion:Hypertension is the leading cause of cardiac disease among the elderly in our setting, emphasizing the necessity to strengthen the preventive strategies against hypertension in Cameroon. Rheumatic heart disease and congenital heart disease frequent in children and youths highlight the need of early detection and treatment of throat infections, and of routine cardiac surgery services in Cameroon.
