ABSTRACT
BACKGROUND: : Dengue is the most important viral diseases globally and a majority of symptomatic infections result in a benign course. However, a small number of patients develop severe manifestations, including myocardial impairment, arrhythmias, and fulminant myocarditis.
AREAS COVERED: This review outlines the incidence of cardiovascular (CV) manifestations of dengue. Electronic databases, including PubMed/MEDLINE, EMBASE, Scopus, and CINAHL were searched for articles incorporating cardiac manifestations of dengue fever (DF).
EXPERT OPINION: : Included studies involved 6,773 patients and 3,122 (46.1%) exhibited at least one cardiac manifestation with DF. Electrocardiogram (ECG) abnormalities (30.6%) included sinus bradycardia (8.8%), non-specific ST-T changes (8.6%), ST depression (7.9%), and T-wave inversion (2.3%). Mechanical sequelae were present in 10.4%, including left ventricular (LV) systolic dysfunction (5.7%), and myocarditis (2.9%). Pericardial involvement was noted as pericarditis (0.1%), pericardial effusion (1.3%), and pericardial tamponade (0.1%). Apart from that, the cardiac injury was depicted through a rise in cardiac enzymes (4.5%). The spectrum of CV manifestations in dengue is broad, ranging from subtle ST-T changes to fulminant myocarditis. This can be a cause of hemodynamic collapse during the critical phase of capillary leakage. Use of contemporary techniques in diagnosing cardiac involvement should be employed for rapid diagnosis and treatment in DF.
