Abstract

The authors evaluated the prevalence of hypothyroidism in patients with heart failure (HF) to determine whether there are racial and sex differences and to determine the number of new cases of hypothyroidism. The study included 194 patients in an HF disease management program (HFDMP) in South Florida. Patients were interviewed for a history of hypothyroidism and referred for measurement of thyrotropin. The prevalence of hypothyroidism was calculated by race and sex. The prevalence of hypothyroidism was 18% for all patients with HF and 23% among Hispanics; however, this trend was not statistically significant (P=06). More men than women had hypothyroidism (P=04). Patients with hypothyroidism had higher mean lipid profiles (P<01) and lower mean heart rates (P=03) than healthy patients. Hypothyroidism is prevalent among HF patients, especially men. Hispanics with HF may have a higher prevalence of hypothyroidism. The standardized protocol of the HFDMP helped identify new cases of hypothyroidism.
