Acceleration rate of mitral inflow E wave: a novel transmitral doppler index for assessing diastolic function

.

The mean value of AR was 1010 ± 420 cm/s² in patients whereas the mean value for the normal controls was 701 ± 210 cm/s². There was a strong and graded relation between AR of E wave of mitral inflow and LV diastolic function grade (Spearman P ≤0.0001, r_s =0.69). ROC curve analysis revealed that AR of E wave of mitral inflow =750 cm/s² predicted moderate or severe LV diastolic dysfunction with 89 % sensitivity and 89 % specificity (area under curve [AUC] = 0.903, P <0.0001). Application of this cutoff on test group showed 96 % sensitivity and 77 % specificity with AUC = 0.932 and P <0.0001.
