ECG & Echocardiographic Changes in Newly Diagnosed Primary Hypothyroidism
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 3
Abstract
Introduction: The cardiovascular system is one of the most important targets of thyroid hormones and is very sensitive to a minimal decrease of circulating thyroid hormones. This study was done to assess the cardiovascular parameters in new hypothyroid patients by using Electrocardiogram and Echocardiography Material and Methods: The present study included 90 patients, and it was conducted at People’s college of Medical Sciences, Bhopal. Thyroid function tests were carried out in patients under study. Electrocardiogram and Echocardiography was also being done in the patients under study. The cardiovascular changes were analyzed with the TSH levels. Results: More than 65% subjects were found to have clinically significant cardiovascular changes. ECG changes observed were Sinus bradycardia in 35.5%, Low voltage complexes in 16.6%, T Wave inversion in 7.8%, RBBB in 4.4%, and QTc prolongation in 2.2% cases. About 64% cases had changes as observed in echocardiographic examination. Most common finding was Diastolic dysfunction seen in 20% cases. This was followed by Pericardial Effusion and Increased IVSD thickness in 16.6% cases each. Increased LVPW thickness was seen in 11.1% cases. Conclusion: This study suggests that it is very important to evaluate patients of primary hypothyroidism for cardiovascular changes so that prior interventions could be performed to improve the clinical outcomes.
