Correlation Of Cardiac Manifestations With Severity Of Dengue Fever

Abstract

Background: Dengue is most rapidly spreading mosquito borne viral disease in the world. In the last 50 years, incidence has been increased 30-fold with increasing geographic expansion to new countries and, in the present decade, from urban to rural setting. An estimated 50-100 million dengue infections occur annually and approximately 2.5 billion people live in dengue endemic countries.
Objective: To find out the correlation of cardiac manifestations with severity of Dengue fever.
Materials and Methods: The cross sectional study was conducted in patients with Dengue Fever admitted in Hospitals attached to Mysore Medical College and Research Institute, Mysore.
Results: Maximum number of cases were between 18 to 30-year age group. Males were more than female population. Fever was present in all patients followed by myalgia (28%) and vomiting (21%). Bleeding manifestation was present in 20% of patients. Thrombocytopenia was present in 91% of patients. No single symptom or sign was statistically significant with severity of dengue. Cardiovascular manifestations were present in 25 patients. Sinus tachycardia was most common ECG finding seen in 17 patients,followed by sinus bradycardia which was seen in 6 patients. 9 patients with cardiac manifestation had dengue fever with warning signs.
Conclusion: There was statistically significant (p=0.007) correlation between cardio-vascular
manifestations with WHO criteria for severity of dengue fever.
