La utilidad de la resonancia magnética nuclear para la evaluación del pronóstico de pacientes con insuficiencia cardíaca según su etiología

Abstract

Importance: The role of magnetic resonance imaging (MRI) in the etiological and prognostic evaluation of patients with heart failure (HF) was discussed. Therefore, we began by describing the usefulness of MRI for the evaluation of prognosis in patients with HF of different etiologies. Observations: Cardiac magnetic resonance (CMR) is superior to echocardiography in assessing left ventricular volumes and function with better reproducibility, also in analyzing systolic abnormalities and characterizing viable myocardial tissue, as well as that with presence of myocardial fibrosis. Precisely, the detection of myocardial fibrosis has a predictive value for adverse events in patients with HF. Conclusions and relevance: CMR is useful to identify previously undetected pathology and pathologies that are difficult to diagnose. Thus, its use is associated with better diagnostic performance and, therefore, a better predictor of adverse events in patients with HF.
