Background: Hypothyroidism, a common endocrine disorder, significantly impacts cardiovascular health and thyroid gland structure. Electrocardiography (ECG), ultrasonography (USG) of the neck, and echocardiography (2D Echo) are essential tools for evaluating these complications. Despite the well-known risks, comprehensive assessments combining these modalities are often underutilized in clinical practice. The study evaluated electrocardiographic, ultrasonographic, and echocardiographic findings in hypothyroid patients to identify prevalent abnormalities and associated risk factors. Methods: A total of 260 hypothyroid patients were included. Data collection involved clinical history, blood tests, ECG, USG neck, and 2D Echo. Statistical analysis was done using SPSS version 20, with qualitative variables analyzed using Chi-square tests and quantitative variables using multivariate analysis and logistic regression. Results: The study revealed that 65% of patients had abnormal ECG findings, with sinus bradycardia (20%) and prolonged QT interval (17%) being most common. USG neck showed thyromegaly in 48.1% and nodules in 40% of patients. Echocardiographic assessment indicated systolic dysfunction in 30% and diastolic dysfunction in 40% of patients. Higher TSH levels were significantly associated with increased prevalence of cardiac dysfunction (p < 0.01). Conclusion: Hypothyroidism significantly affects both cardiac function and thyroid gland structure. The study underscores the necessity for comprehensive diagnostic assessments, including ECG, USG, and echocardiography, to detect and manage complications early. Effective control of thyroid function is crucial in mitigating cardiovascular risks. Recommendations: Regular monitoring of thyroid and cardiac health in hypothyroid patients is recommended. Future research should focus on long-term outcomes of integrated diagnostic assessments and the effectiveness of early interventions.
