Resumen

AVILA-SANCHEZ, Diego Alberto. Resonancia magnética cardíaca en la miocardiopatía chagásica crónica. Una herramienta para optimizar el diagnóstico, la estratificación de riesgo y el pronóstico. Rev. costarric. cardiol [online]. 2020, vol.22, n.1, pp.60-67. ISSN 1409-4142.

Chagas disease is a public health problem in Latin America, where it affects approximately 6 million people. In Costa Rica the disease has been described since 1941, with several reports of acute and chronic confirmed cases. Chagas cardiomyopathy affects 30% of individuals with chronic infection and is the most serious manifestation of the disease, with a higher morbidity and mortality than other cardiomyopathies. Cardiac magnetic resonance, due to its capacity for tissue characterization, identifies the presence of fibrosis, aedema and inflammation in Chagas cardiomyopathy with high histopathological correlation. This has allowed a better understanding of the complex pathophysiology of the disease and also allows differential diagnosis with other pathologies that can simulate, such as ischemic heart disease. In Chagas cardiomyopathy, the presence of myocardial fibrosis independently predicts major adverse events such as sustained ventricular tachycardia and cardiovascular death. Due to the above, cardiac magnetic resonance is a robust tool capable of improving the diagnosis, risk stratification and prognosis of these patients, with a view to better and timely therapeutic interventions.
