Congenital Hypothyroidism, Withdrawal of Thyroxin Supplementation, and Heart Failure in Dilated Cardiomyopathy: Case Report and Review of Literature

Heart failure (HF) is a major world health problem and has been described as a global scourge, with varied epidemiology, affecting about 64.3 million persons worldwide. In Africa, the impact of HF is huge and responsible for as much as 30%-50% of cardiovascular cases seen in hospitals. The report of HF in hypothyroidism is more in Western and Asian countries but rarely seen in Africa and other developing nations. This is a case report of HF in an adult with congenital hypothyroidism, precipitated by discontinuation of thyroxine supplementation.
