Cardiovascular Manifestations of Hyperthyroidism

Abstract

Wilbert S Aronow

Gupta et al. reported an excellent case report of an acute myocardial infarction caused by thyrotoxicosis in a 23-year old man with a normal coronary angiogram [1]. Acute myocardial infarction may occur in patients with hyperthyroidism and normal coronary arteries due to major coronary artery occlusion by coronary vasospasm induced by a hyperadrenergic state with stimulation of adrenergic receptors on coronary arteries and increased myocardial oxygen demand.
