Predict late gadolinium enhancement using left ventricular long-axis strain in multiple myeloma with secondary cardiac amyloidosis patients

The purpose of this study was to evaluate the function of left ventricular (LV) in multiple myeloma (MM) with secondary cardiac amyloidosis (MM-CA) patients by cardiac magnetic resonance feature tracking (CMR-FT), and investigate the role of simple and fast CMR-FT long-axis strain (LAS) analysis in predicting late gadolinium enhancement (LGE). The results showed the LV function was more impaired in enhanced (LGE+) than in no-enhanced (LGE-) MM-CA patients. Among the investigated CMR-FT parameters, the LV LAS presented with best prediction efficacy of LGE. Our study indicated the simple and fast LAS may be beneficial for MM-CA patients with renal failure.
