Abstract

OBJECTIVE:

The study aimed to assess whether the mitral peak Doppler E-wave to peak mitral annulus velocity ratio (E/Ea) estimates left ventricular (LV) filling pressure (LVFP) and predicts mortality in end-stage renal disease.

METHODS:

In all, 125 candidates for renal transplant were prospectively studied. LV end-diastolic pressure of 15 mm Hg or greater at cardiac catheterization was defined as elevated LVFP.

RESULTS:

Severe coronary artery disease, N- terminal pro-B-type natriuretic peptide level, left atrial size, flow propagation velocity, mitral E/Ea ratio, pulmonary atrial reversal velocity, and pulmonary-mitral atrial wave duration predicted an increased LVFP. However, the mitral E/Ea ratio (odds ratio 8.1, 95% confidence interval 5.1-9.6, P = .003) was the only independent predictor. An E/Ea of 15 or more, seen in 31 (25%) patients, predicted increased LVFP with sensitivity of 82% and specificity of 88%, and was associated with increased mortality (P = .005).

CONCLUSIONS:

In end-stage renal disease, mitral E/Ea ratio 15 or higher accurately predicts increased LVFP and mortality.
