| Abstract |
|
Thyroid hormone has many effects on the heart and vascular system. Cardiovascular manifestations of excess thyroid hormone are variable, and include enhanced cardiac contractility, enhanced oxygen myocardial consumption, and reduced systemic vascular resistance. Sinus tachycardia, atrial fibrillation, heart failure, and angina pectoris are common clinical manifestations, while right heart failure without severe left heart failure is rare in patients with hyperthyroidism. In addition, ventricular fibrillation may occur in thyrotoxic patients due to myocardial ischemia, such as in variant angina. This case report describes a young woman who presented with right heart failure and variant angina, whose only concurrent illness was hyperthyroidism. The symptoms and sign of right heart failure improved on treating the hyperthyroidism. |
