ABSTRACT

Thyroid dysfunction, whether it be from an increase or decrease in the levels of thyroid hormones, has multiple repercussions in the cardiovascular system which have been associated with an increase in mortality and heightened risk of cardiovascular events. This risk must be taken into consideration when evaluating patients with thyroid dysfunction in order to include strategies that assure a timely diagnosis and treatment of the above-mentioned complications. Similarly, it is necessary to evaluate the thyroid function in patients who present cardiovascular events such as heart failure, arrhythmias, coronary acute syndrome or acute stroke. Some of these alterations will cease with the recovery of euthyroidism. Randomized controlled trials are needed to define the best way to treat these patients, especially in cases of subclinical hypothyroidism, where it is still unknown if treatment with L-thyroxin helps reducing cardiovascular risk...
