Study of Cardiac Symptoms in Dengue Infection Patients Visiting a Tertiary Hospital

Background: One of the most significant viral diseases that is linked to mortality is dengue fever. Clinical signs of cardiac involvement might range greatly, from a quiet illness to a fatal myocarditis. Aims & objectives: The goal of the current investigation was to evaluate the cardiac effects of dengue fever and find any subclinical or latent cardiac involvement. Material and Methods: Patients who were above the age of 18, of either gender, were admitted with a diagnosis of dengue fever (confirmed by a serological test) and were willing to participate in the study. Results: 284 patients who met the inclusion and exclusion criteria for the study were evaluated. The age range of 31–40 years represented the largest percentage of patients (28%) followed by that of 41–50 years (12%). (23 percent ). In this study, men made up the majority (57%) of the patients. According to serology results, the majority of patients were IgG (+20%), IgM (+20%), and NS1 (+48%) positive (13 percent ). In the current study, 15% of participants tested positive for troponin T, and 18% had high CK-MB values (> 25). Sixty percent of patients had normal electrocardiograms; noteworthy findings included broad QRS complex (11%), diffuse T wave inversion (10%), non-specific ST segment changes (10%), sinus bradycardia (9%), and low voltage QRS complex (0.70 percent ). Significant 2D ECHO findings were anterior wall hypokinesia (3%) minor PAH + mild TR + hypokinesia anterior wall (1%) mild PAH + mild TR (0.70%), LVH (0.70%), DCM secondary to dengue myocarditis (0.70%), and mild AML prolapse. In 93 percent of patients, the 2D ECHO was normal (0.70 percent ). Conclusion: Patients with dengue fever who have transient cardiac abnormality—as indicated by changes in heart rate, rhythm, and elevated CK MB and troponin I levels—should continue extensive assessment and follow-up even after being discharged.
