INTRODUCTION: dengue is the most common worldwide viral disease transmitted by dissemination vectors. Its clinical spectrum comprehends atypical manifestations including cardiac involvement, from which only few series of cases have been reported in the literature. OBJECTIVE: to report the clinical characteristics of patients treated for serologically confirmed cases of dengue with cardiovascular events in a Colombian cardiovascular referral center during the epidemic of 2010. METHODS: an observational, descriptive, prospective study, which included patients presenting to the emergency service and had a confirmed diagnosis of dengue with cardiovascular manifestations of the disease. RESULTS: 7 patients met the inclusion criteria. 50% had no prior history of cardiovascular disease. Rhythm disorders were the most common cardiac manifestation (42.8%), including de novo atrial fibrillation (14.2%), complete atrioventricular block and transient (14.2%), sinus bradycardia concomitant with pericardial effusion (14.2%) and mild ventricular dysfunction (28.5%). One patient had an acute coronary syndrome with ST elevation during infection and two had acute decompensated heart failure. No deaths were reported. CONCLUSION: the incidence of cardiac complications associated with dengue infection varies from one series to another and its pathophysiology is not completely understood. During the epidemic that occurred in Colombia in 2010 there were few cases with cardiovascular symptoms but with significant morbidity that should alert regarding its early identification.
