Relationship between the change in left ventricular ejection fraction (ΔLVEF) and change in left ventricular diastolic dimension (ΔLVDd) at 4 years at the latest time point of observation. Relationship between the change in left ventricular ejection fraction (ΔLVEF) and change in left ventricular diastolic dimension (ΔLVDd) at 4 years at the latest time point of observation. At both time points of observation, ΔLVEF and ΔLVDd exhibited a strong significant correlation, indicating that these changes appeared in each patient proportionally. See text for details.
