Keywords: Myocardium, Cardiomyopathy
Motivation: CMR first-pass-perfusion imaging (FPI) had revealed coronary microvascular dysfunction (CMD) in dilated cardiomyopathy (DCM). However, it’s unknown if FPI could predict left ventricular reverse remodeling (LVRR) in DCM.
Goal(s): Investigating the value of FPI parameters for predicting LVRR.
Approach: 94 DCM patients and 35 healthy controls were enrolled. FPI as well as the left ventricular structure, function and late gadolinium enhancement (LGE) parameters were analyzed.
Results: FPI showed more serious CMD in non-LVRR than LVRR. Timemax of FPI as well as left ventricular remodeling index and LGE extent were independent predictors.
Impact: This study firstly showed the role of FPI in predicting LVRR in DCM.
