Abstract
Background: Dilated cardiomyopathy (DCM) is a primary myocardial disease of unknown cause characterized by left ventricular or biventricular dilatation and impaired myocardial contractility. Morbidity and mortality in patients with DCM remain high. Data on DCM outcomes in Africa are lacking. This study aimed to determine the clinical characteristics and outcome of DCM at University College Hospital, Ibadan, Nigeria.
 
Methods: Analysis of data collected over 6 years (September 1, 2016, through August 31, 2022). Information included sociodemographics, clinical features, echocardiographic diagnosis, morbidity, and mortality.
 
Results: During this period, 127 cases of DCM were seen: 91 males (71.7%) and 36 females (28.3%) aged 52.0 (SD, 16.0) years (range, 17–86 years). More than 90% had formal education, and 108 (85%) were married. A history of current or past alcohol consumption was documented in 62 (48.5%). At 1-year follow-up, 27 (21.3%) of the 127 patients died. Those who died were older and had higher body mass index and white blood cell count but lower estimated glomerular filtration rate, systolic blood pressure, and sodium level. Decedents were more likely to be male (P = 0.018) and to consume alcohol (P = 0.029).
 
Conclusions: Our data show that male sex and alcohol use are predictors of mortality in patients with DCM seen at UCH Ibadan. (Iranian Heart Journal 2026; 27(1): 26-36)
