Abstract
Over a period of 6 years, only twelve cases of dilated cardiomyopathy were clinically diagnosed in Nigerians between the ages of 11-30 years at the University College Hospital, Ibadan, Nigeria. Eleven presented with heart failure, while the twelfth patient presented with a cerebrovascular accident. Two other patients also had a cerebrovascular accident. A history of febrile illness was obtained in seven, but in only three was fever unresponsive to antimalarials, documented on admission. Antistreptolysin-O titre was normal and erythrocyte sedimentation rates elevated in each of the patients. Leucocytosis was present in six, three had a four-fold rise or fall in antibody titres against Coxsackie-B viruses and one, a four-fold rise or fall against Toxoplasma gondii. Histological evidences of myopericarditis were found in three of the six patients who died. It is concluded that dilated cardiomyopathy is rare in young adult Nigerians, and that constitutional upset is common, as in children, but prognosis is poorer. Infections by Coxsackie-B viruses, T. gondii and possibly other viruses appear to be of major aetiological factors
