PEREZ, Walter et al. Afectación cardíaca en el curso de infecciones respiratorias agudas virales.: Reporte preliminar. Arch. Pediatr. Urug. [online]. 2010, vol.81, n.3, pp.141-145. ISSN 1688-1249.

Acute viral respiratory infections are one of the most important causes of illness and death in children around the world. In Uruguay, acute respiratory infections are the cause of hospital admissions in the cold months and a prevalent admission cause to be admitted in intensive care. Myocardial involvement has been described as a major complication in the evolution of the disease. Objectives: to know the prevalence and severity of heart illness in the course of the low viral load acute respiratory infections and assess the usefulness of troponin T to find myocardial compromise. Material and methods: prospective descriptive study. We included IRABV carriers, admitted to the hospital, of up to two years. All RX chest, ECG, troponin T serum and Echocardiogram tests performed. Follow-up to those which presented affectation ECG, ECO or troponin test took place. Results: 80 patients were included. VRS was the etiology in 53%. The ECG evidenced unspecific alterations of the repolarization in 17%. The presence of pericardial effusion was described in 9% of cases. These alterations were not associated with the seriousness or etiology. Troponin was increased by 4% without significant association with the analyzed variables. CPK in these patients was normal. There were no deaths in this sample. Conclusions: frequent heart alterations by the ECG and ECO became apparent but were not associated with requirements of intensive care or mechanical ventilation. Troponin was increased in 4 per cent of cases but it was not linked to the evolution of patients.
