Cardiac Manifestations In Dengue: A Cross-Sectional Study From A Tertiary Care Center In South India. Indian Journal Of Applied Research. 2025 Jul; 15(7): 21-222249-555Xhttps://imsear.searo.who.int/handle/123456789/253447Background: Dengue, a mosquito-borne viral illness endemic to tropical regions, can lead to a wide spectrum of systemic complications. Among these, cardiac involvement is increasingly recognized but often underdiagnosed. Objective: To assess the incidence and pattern of cardiac manifestations in dengue fever patients admitted to a tertiary care hospital in South India. A cross-sectional study was conducted on 100 serologically confirmed dengue patients. All patients underwent clinicalMethods: examination, electrocardiography (ECG), 2D echocardiography (ECHO) and Troponin I in selected patients. Exclusion criteria included pre- existing cardiac disease or medications affecting cardiac rhythm. Cardiac abnormalities were identified in 45% of patients. ECGResults: findings included sinus tachycardia (24%), bradycardia (15%), ST-T changes (11%), T-wave inversions (10%), and ventricular arrhythmias (3%). Echocardiographic findings included reduced ejection fraction (11%), diastolic dysfunction (7%), pericardial effusion (6%), and right-sided chamber dilatation (4%). Cardiac manifestations correlated positively with dengue severity. Cardiac manifestations in dengue areConclusion: common but often subclinical. Routine ECG and echocardiographic evaluation should be considered to enable timely diagnosis and prevent complications.Journal ArticleIndiaJR, M.D. General MedicineJR, M.D. General Medicine
