Cardiac involvement in patients of dengue fever in reference to ECG and Echocardiography – A tertiary care center study
Introduction: Dengue rarely affects the heart but clinical symptoms of cardiac involvement may range greatly from silent illness to severe myocarditis resulting in death. Clinical features are asymptomatic and most are transient among patients with DF/DHF.
Material and methods: It was an observational study conducted at the Department of General Medicine, Peoples College of Medical Sciences and Research Centre, Bhopal. The total duration of the study was One and a half years from Dec 2018 to May 2020. All dengue patients presenting to People’s Hospital during one and half years from which data was collected using as per given proforma.
Results: In the present study group of 58 patients, it was found that 49 patients (84.5%) have not shown any cardiac abnormalities and 9 patients have abnormal values (15.5%) but are not significant. It is also found that the incidence of cardiac manifestations was more common in DHF and dengue shock syndrome which was 15.5% and 3.4%, respectively.
Conclusion: Clinical manifestations of cardiac involvement can vary widely from silent disease to severe myocarditis resulting in death. Rhythm abnormalities, hypotension, arrhythmias, myocarditis, myocardial depression with symptoms of heart failure and shock, and pericarditis have been reported. Involvement of multiple organs, as well as the presence of metabolic derangement, can further confuse the picture.
