Hyperthyroidism and heart failure
Abstract
Heart failure is a public health problem. Atrial fibrillation is the most frequently associated clinical arrhythmia. The concomitant presentation of both entities portends a worse prognosis. The etiology of cardiac dysfunction is imperative to determine treatment. Amongst these are thyroid diseases. About 6% of patients with hyperthyroidism present with heart failure as the only clinical problem. We present a patient with heart failure and atrial fibrillation, where the etiology was determined to be hyperthyroidism. The patient presented no additional symptoms or signs of hyperthyroidism (subclinical hyperthyroidism; <3% of cases). Optimal medical therapy was administered including ablation of the thyroid gland with radioactive iodine, and successful synchronized electrical cardioversion. The clinical progress was excellent once the euthyroid state was achieved and she remained in sinus rhythm.Downloads
