Background: Dengue fever is a major mosquito-borne viral illness with increasing incidence in tropical countries. Apart from classical manifestations, dengue may involve multiple organs including the cardiovascular system. Cardiac manifestations range from asymptomatic electrocardiographic abnormalities to myocarditis, arrhythmias, left ventricular dysfunction, and cardiogenic shock. Early identification of cardiac involvement is important for appropriate management and prevention of complications.
Aim:: To evaluate the pattern and prevalence of cardiac manifestations in adult patients with dengue fever admitted to a tertiary care hospital.
Objective: To assess electrocardiographic abnormalities in dengue patients.
• To evaluate echocardiographic changes in dengue fever. • To determine the association of cardiac enzyme abnormalities with severity of dengue.
• To assess electrocardiographic abnormalities in dengue patients.
• To evaluate echocardiographic changes in dengue fever.
• To determine the association of cardiac enzyme abnormalities with severity of dengue.
Materials and Methods: This hospital-based cross-sectional study was conducted in the Department of General Medicine, Rohilkhand Medical College & Hospital, Bareilly, Uttar Pradesh. Adult patients diagnosed with dengue fever based on serological confirmation were included in the study. Detailed clinical evaluation, laboratory investigations, serial electrocardiography, cardiac enzyme assessment, and echocardiography were performed. Statistical analysis was carried out using SPSS software. A p-value <0.05 was considered statistically significant.
Results: Cardiac manifestations were observed in a significant proportion of dengue patients. The most common ECG abnormality was sinus bradycardia followed by ST-T changes and atrioventricular conduction disturbances. Echocardiography revealed transient left ventricular dysfunction and mild pericardial effusion in selected patients. Elevated cardiac biomarkers were associated with severe dengue and warning signs. Most abnormalities were transient and resolved with supportive treatment.
Conclusion: Cardiac involvement in dengue fever is common and often subclinical. Serial ECG monitoring and selective echocardiographic evaluation aid in early recognition of myocardial involvement. Early diagnosis and appropriate monitoring can improve clinical outcomes in dengue patients.
