2015, Heart Lung and CirculationCitation Excerpt :In patients with LV hypertrophy and dilated cardiomyopathy, R-pE’ was delayed more than those age-matched subjects. [4,16,31] Furthermore, in patients with LV hypertrophy and dilated cardiomyopathy, R-pE’ adversely preceded peak E. [4,31] In our study, we found that during LV early diastole, the R-pE showed no significant changes, but R-pE’ was delayed, and thus the resultant EDTD (i.e., the time difference of R-pE and R-pE’) was significantly decreased in patients with HF compared with normal controls. When LV relaxation is impaired, LV filling is compensated by augmenting LA contraction. [32]
