Thyroid hormones have a direct effect on the heart
Patients with hypothyroidism or hyperthyroidism have increased risk of cardiovascular disease
Treatment with thyroid hormones in patients with hypothyroidism improves cardiovascular risk factors, but the effect on cardiovascular events has not been assessed in randomized, controlled trials
In experimental settings, thyroid hormones influence myocardial remodelling and function after myocardial infarction, but the utility of thyroid hormone replacement therapy in patients with acute cardiac events is yet to be elucidated
Intracellular and circulating thyroid hormone concentrations (mainly T3) decrease after acute myocardial infarction and in chronic heart failure, and this reduction is associated with poor outcomes
Small studies showed that treatment with thyroid hormones is safe and beneficial in patients with chronic heart failure; however, larger, adequately powered trials are required to confirm safety and assess efficacy
Myocardial and vascular endothelial tissues have receptors for thyroid hormones and are sensitive to changes in the concentrations of circulating thyroid hormones. The importance of thyroid hormones in maintaining cardiovascular homeostasis can be deduced from clinical and experimental data showing that even subtle changes in thyroid hormone concentrations — such as those observed in subclinical hypothyroidism or hyperthyroidism, and low triiodothyronine syndrome — adversely influence the cardiovascular system. Some potential mechanisms linking the two conditions are dyslipidaemia, endothelial dysfunction, blood pressure changes, and direct effects of thyroid hormones on the myocardium. Several interventional trials showed that treatment of subclinical thyroid diseases improves cardiovascular risk factors, which implies potential benefits for reducing cardiovascular events. Over the past 2 decades, accumulating evidence supports the association between abnormal thyroid function at the time of an acute myocardial infarction (MI) and subsequent adverse cardiovascular outcomes. Furthermore, experimental studies showed that thyroid hormones can have an important therapeutic role in reducing infarct size and improving myocardial function after acute MI. In this Review, we summarize the literature on thyroid function in cardiovascular diseases, both as a risk factor as well as in the setting of cardiovascular diseases such as heart failure or acute MI, and outline the effect of thyroid hormone replacement therapy for reducing the risk of cardiovascular disease.
