Hypothyroidism is a clinical syndrome resulting from deficiency of thyroid hormones in the target tissues. . Primary hypothyroidism is common worldwide especially in iodine deficient areas like India. In non-endemic areas chronic autoimmune thyroidectomy and destructive treatment of thyrotoxicosis are common. . The yearly incidence of spontaneous hypothyroidism per 1000 was estimated to be 3.5 and 0.6 in females and in males respectively¹. The cardiovascular abnormalities associated with thyroid dysfunction, remain barely unattended which ultimately lead to heart failure and death. Here we have made a modest attempt to define the clinical spectrum of hypothyroidism with special reference to cardiovascular manifestation

Aims and Objectives: 1. To study correlation of symptomatology with serum thyroid hormone levels.

2. To study the cardiovascular changes associated in hypothyroidism.

3. To study co-morbid condition associated with hypothyroidism

Methods and Material: This study was conducted on 100 patients admitted in S.G.M.H. REWA, >12 years of age showing  signs and symptoms of hypothyroidism or known case of hypothyroidism and detailed history, physical examination, thyroid profile, ECG, 2D-echocardiography were done.

Result: The most common ECG feature was nonspecific ST-T wave changes in 77.61% Low voltage complexes were seen in 37.31%, prevalence of low voltage complexes was higher in the group with TSH levels >10 mili IU/l, pericardial effusion was present in 37.5% and left ventricular hypertrophy in 23.43%. the prevalence of pericardial effusion was higher in the group with TSH levels >10 mili IU/l,the clinical parameters were more abnormal in the group with TSH levels >10 mili IU/l

Conclusion: Hypothyroidism is a multitude of clinical presentations involving various systems in the body. cardiovascular disease are very common among these patients physicians should suspect hypothyroidism from the subtle signs and symptoms of the disease so that an early diagnosis and timely treatment is initiated.
