abstract = {Objective: The purpose of the study was to investigate the influence of late gadolinium enhancement (LGE) on the diastolic volume recovery of left ventricle in patients with hypertrophic cardiomyopathy (HCM).
Methods: Twenty-four HCM patients were studied through report-card 4.0. The presence or absence of late gadolinium enhancement was recorded according to a standardized methodology with a threshold value of six standard deviations above background. The LGE positive and negative groups were correlated to left ventricular end diastolic volume index (EDVI), left ventricular mass, left ventricular ejection fraction (EF), peak filling rate (PFR), peak ejecting rate (PER), normalized peak filling or ejecting rate (NPFR or NPER), time to peak filling or ejecting rate (TPFR or TPER), and diastolic volume recovery (DVR).
Results: PFR, NPFR, SV, SVI, EF, CO, CI, FS in LGE positive group were lower than LGE negative group, DVR10-40, DVR100, end systolic volume (ESV), end systolic volume index (ESVI), ESD were higher in LGE positive group, and the differences were statistically significant. The average LGE mass (ROI, region of interest) was 20.78 g, about 13.67% of left ventricle mass in LGE positive HCM group. Pearson correlation was noted between the LGE percent (ROI%) and ESV (0.692, P},
