Background: The sign and symptoms produced by hypothyroidism is a major cause of morbidity but the effect of hypothyroidism on cardiovascular system and its complication can be the cause for one’s morbidity & mortality if they goes unnoticed and if not addressed in a proper way and at appropriate time. Aims and objectives: To determine the pattern of cardiao-vascular complications in hypothyroid patients. Materials and Methods: Two hundred newly diagnosed hypothyroid patients were studied from January 2017 to June 2018 at the Hamidia Hospital of Bhopal city. All the patients were subjected to medical examinations for thyroid profile, blood pressure, lipid profile, electrocardiography, color Doppler heart, chest x-ray PA were performed. Results: Dyslipidemia was more prevalent and more severe in overt hypothyroidism (OH) patients with respect to total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) except for triglycerides, the derangement of which is having similar prevalence in both overt hypothyroidism (OH) and subclinical hypothyroidism (SH). In subclinical hypothyroid patient 27.27% and 54.44% had patients had increased blood pressure. A total 22.22% of overt hypothyroid patients and 7.27% of subclinical hypothyroid patient have pericardial effusion. More than half of patients (55.56%) of overt hypothyroidism had bradycardia in their ECG while only 4.55% in subclinical group showed it. 48.89% in overt hypothyroid group and 11.82%in subclinical group showed low voltage complex in their ECG (p<0.001). Conclusion: Hypothyroidism is evidently linked with cardiao-vascular complications which are more prevalent and more severe in overt hypothyroidism cases, hence should be considered while management of it.
