Prevalence of myocardial involvement due to dengue in adult patients at Hernando Moncaleano University Hospital Perdomo de Neiva

Abstract

Introduction: Dengue fever (DF) is an acute viral disease caused by an arbovirus of the Flaviviridae family, transmitted by Aedes vectors. It causes high morbidity and mortality and economic condition in the tropical and subtropical regions of the world, in the region of Latin America, the number of dengue cases has increased significantly in the last 25 years. Materials and Methods: A descriptive, retrospective study, cross where the patient population was analyzed diagnosed with dengue were admitted to the internal medicine at University Hospital Hernando Moncaleano Perdomo city of Neiva, Huila who presented a myocarditis. Results: 35 patients with myocardial involvement were found. 68.5% were women and 31.4% men; 90% of patients had dengue with warning signs; The most frequent electrocardiographic changes were: sinus bradycardia (88.57%); the anterior hemiblock, right bundle branch block, cardiac arrhythmia and supraventricular extrasystole 5.7% each. Echocardiography reported: that 71.4% had LVEF> 50%; 28.4% LVEF <40%; 57.1% had mitral and tricuspid regurgitation, 28.6% systolic and diastolic spread each; Ventricular hypertrophy 42.8% and 28.6% myocarditis. Conclusions: The female gender was predominant followed by risk factors such as being older than 50 and have obesity. The most common electrocardiographic finding was sinus bradycardia, and echocardiography of atrioventricular valve insufficiency. The therapeutic approach that more was done was the administration of intravenous fluids and acetaminophen. Taking electrocardiogram in the emergency department is not a routine paraclinical adult patients with dengue, because of this, not all cases are diagnosed with myocardial involvement.
