The mean age of the subjects with heart failure was 42.3 \u00b1 0.9 years. The male to female ratio was 1.2:1.0. Combined heart failure was seen in 50.5% of subjects. Peak incidence of heart failure occurred in the 5th decade. The main causes of heart failure were hypertension (21.3%; n = 122), rheumatic heart disease (20.1%; n = 115) and cardiomyopathy (16.8%; n = 96). Congenital heart disease and coronary artery disease accounted for 9.8 and 10% of cases, respectively. The commonest rheumatic valvular lesion was mitral regurgitation (78%). Dilated cardiomyopathy was the commonest form of idiopathic cardiomyopathy (67.7%; n = 65). Endomyocardial fibrosis and hypertrophic cardiomyopathy accounted for 22.9% (n = 22) and 9.4% (n = 9), respectively, of cardiomyopathies.<\/jats:p>","DOI":"10.1159\/000006996","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T15:42:49Z","timestamp":1050421369000},"page":"11-18","source":"Crossref","is-referenced-by-count":75,"title":["Aetiology of Heart Failure as Seen from a National Cardiac Referral Centre in Africa"],"prefix":"10.1159","volume":"93","author":[{"given":"A.G.B.","family":"Amoah","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Kallen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2000,7,4]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(96)07493-4"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.153.2.154"}],"container-title":["Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/6996","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/6996","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:36:57Z","timestamp":1745469417000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000006996"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000]]},"references-count":2,"journal-issue":{"issue":"1-2","published-online":{"date-parts":[[2000,6,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000006996","archive":["Portico"],"relation":{},"ISSN":["0008-6312","1421-9751"],"issn-type":[{"value":"0008-6312","type":"print"},{"value":"1421-9751","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000]]}}}
