Evaluation of the Echocardiographic Findings in cases of Thyroid Disorders Authors

Background: Thyroid disorders are known to cause cardiac complications and increases risk of cardiac morbidity and mortality. This study aimed to identify echocardiographic changes in thyroid disorders. Methods: Data was examined from 90 patients by dividing into three groups having 30 patients in each group as hyperthyroid, hypothyroid and control group respectively. Echocardiography was done before initiation of therapy and after 12 weeks of therapy. Result: Diastolic dysfunction was seen in both Hyperthyroid (13.33%) and Hypothyroid (46.67%) with more prevalence in Hypothyroid group, MR was common in Hyperthyroid group (20%), Hypothyroid group (13%). The flow velocities with hypercontractile heart (20%), pulmonary hypertension (20%), concentric LVH (10%), irregular rhythm and mild pericardial effusion (3.3%) in Hyperthyroid group. In Hypothyroid group pericardial effusion (23.3%), concentric LVH (23.3%), asymmetric hypertrophyof septum (3.3%), dilated LV (3.3%) was seen. All changes reverted significantly after 12 weeks of therapy and it was statistically significant (p<0.05). Conclusion: Early echocardiography in patients of thyroid disorders is helpful for early diagnosis of cardiac complications associated with it and timely prevention. Introduction Thyroid disease is quite common it affects as many as 9% to 15% of the adult female population and a smaller population of adult males. 1 Hyperthyroidism and hypothyroidism are known to effect cardiovascular system in a number of ways. 2 In hyperthyroidism, excessive thyroid hormone production and thyrotoxicosis, subclinical hyperthyroidism are associated with palpitations, tachycardia, exercise intolerance, dyspnea on exertion, widened pulse pressure and sometimes atrial fibrillation. Cardiac contractility is enhanced and resting heart rate and cardiac output are increased. Cardiac output may be increased by 50%300% over that of the normal subjects as a result of combined effects of increased in resting heart rate, contractility, ejection fraction and blood volume with decrease www.jmscr.igmpublication.org Impact Factor 5.84 Index Copernicus Value: 83.27 ISSN (e)-2347-176x ISSN (p) 2455-0450 DOI: https://dx.doi.org/10.18535/jmscr/v5i5.98
