Abstract

Introduction and Aim: Raised cardiovascular morbidity is common among patients with primary hypothyroidism. Study of electrocardiogram (ECG) and echocardiography (ECHO) and correlation with lipid profile may help in early detection of cardiovascular diseases in hypothyroidism. By this study, we aimed at studying the cardiovascular profile in patients with primary hypothyroidism and correlating ECHO and ECG changes in primary hypothyroidism with the LDL cholesterol. Materials and Methods: This was a single centre cross-sectional observational study. All patients diagnosed with primary hypothyroidism were included. The laboratory parameters pertaining to primary hypothyroidism were recorded. ECG and ECHO were noted and correlated with lipid profile. Results: Total 240 subjects were selected according to inclusion and exclusion criteria, of which males were 25% and females 75%. Mean ± SD of LDL-C among subjects having ST-T changes was 160.98 ±14.86. Mean ± SD of LDL-C among subjects having no ST-T changes was 128±10.15. Unpaired student t test was used to compare mean of lipid profile in patient having ST-T changes with patients having no ST-T changes. A strong correlation was observed between LDL cholesterol and ST-T changes in ECG (P value =0.001) Conclusion: Diastolic dysfunction is more common than systolic dysfunction in primary hypothyroidism. LDL levels were high in patients with primary hypothyroidism who had ST-T changes in electrocardiogram. Levothyroxine replacement causes decrease in Total as well as LDL cholesterol in primary hypothyroidism. ECG changes correlated with abnormal lipid profile in patients with primary hypothyroidism.
