BACKGROUND: Heart type fatty acid binding protein (H-FABP) is a small protein and released into the circulation when myocardial damage has occurred. Previous studies have demonstrated that H-FABP is closely associated with cardiac and some endocrinologic disorders including prediabetes, metabolic syndrome, and acromegaly. Hyperthyroism is a well-known disorder associated with cardiovascular diseases. We aimed to investigate the effect of hyperthyrodism on H-FABP levels.
METHODS: Forty six patients with hyperthyroidism with no known history of coronary artery disease and 40 healthy controls are involved in the study. Serum H-FABP levels are measured using sandwich enzyme-linked immunosorbent assay.
RESULTS: There was no significant difference between serum H-FABP levels of patients with hyperthyroidism and controls (871±66 pg/mL, and 816±66 pg/mL, respectively P=0.56). There was no significant correlation between H-FABP, free triiodothyronine (fT3), free thyroxine (fT4), and thyroid stimulating hormone (TSH) levels in patients and controls.
CONCLUSIONS: Serum H-FABP levels are not altered in patients with hyperthyroidism.
