Abstract
Background: Dengue fever is one of the common viral fever in tropical countries. It has many systemic complications, But the effects of Dengue fever on Heart is not clearly studied in literature. In this study we are evaluating whether there were any cardiac manifestations in patients affected with dengue fever.
Aims and Objectives: To study the cardiac manifestations in dengue fever.
Method: This one and half year descriptive study was undertaken at Kempegowda Institute of Medical Sciences and Research Center, Bengaluru in the Department of Medicine. A total of 60 patients with dengue NS1Ag and/ IgM were studied cardiac manifestations in dengue was assessed based on electrocardiogram, 2D echocardiography and cardiac enzymes
Results: A total of 60 patients were included in the study out of which 41(68%) male and 19(32%) female patients and the male to female ratio was 2.1:1. Minimum age was 18 years and maximum age was 78 years .The mean age of the patients was 36.8 years. The commonest clinical presentation was retro orbital pain (85%) followed by fever (76.6%). CK-MB was elevated in 2 cases (3.3%) and Troponin I was elevated in 2 cases (3.3%).Most common cardiac abnormalities noted was sinus bradycardia, found in 53.33 percent. Cardiac manifestation in the form of myocarditis was observed in 2 patients (3.3%)
Conclusion: The most common cardiac manifestations noted were sinus bradycardia and was transient. There were 2 cases with myocarditis, 1 case with first degree AV block, 1 case with LBBB, 1 case with Atrial fibrillation, 1 case with complete heart block. Patients with dengue fever are at high risk of cardiac manifestations including myocarditis and heart blocks. Therefore, require a close cardiac monitoring.
Keywords: Dengue, Heart, Myocarditis, Complications, AV Block, Cardiac manifestations.
