Abstract

Background: Thyroid hormones directly affect the heart and cardiovascular system. Cardiovascular symptoms like hypertension, palpitations, dyspnoea, chest pain, pedal edema and exercise intolerance are common presenting symptoms of hyperthyroidism. These symptoms usually revert back to normal when a euthyroid state is restored and maintained with help of antithyroid drugs initially and a definitive treatment later. Hyperthyroid patients can be easily evaluated using two non invasive modalities namely electrocardiography and echocardiography. This study aims at understanding the various electrocardiographic and echocardiographic manifestations of newly diagnosed patients with overt hyperthyroidism.

Aim: To evaluate electrocardiographic and echocardiographic manifestations of newly diagnosed adult patients suffering with overt hyperthyroidism.

Methods: 77 patients with overt hyperthyroidism who visited the thyroid clinic of Institute of nuclear medicine and allied science (INMAS), Timarpur, Delhi were enrolled for the present study. All the patients were asked about the symptoms including cardiac symptoms with the help of a structured questionnaire. Detailed clinical, biochemical evaluation and nuclear imaging was done for all the patients and it included estimation of freeT3, free T4, TSH, Technetium 99 scan and Radio-active iodine uptake. Cardiovascular evaluation included a 12 lead resting electrocardiogram (ECG) and a two dimensional transthoracic echocardiogram.

Conclusion: Symptoms pertaining to cardiovascular system are the common presenting feature in patients with hyperthyroidism. Apart from clinical examination of the cardiovascular system electrocardiography and echocardiography are two non-invasive modalities that can evaluate the cardiac abnormalities in such patients.
