The left diastolic ventricular dysfunction was frequently found in patients with chronic renal fealure. Abnormalities of diastolic function were detected in 50% to 60% of hemodialysis patients.

Describe the prevalence of abnormalities in left diastolic ventricular function in our population and to identify predictors of this heart defect.

A retrospective study on 92 patients treated with chronic hemodialysis at dialysis center of UH of Ibn Rochd of Casablanca, between January 2012 and May 2014. All patients benefited from a transthoracic echocardiographic study.

The average of early transmitrale velocity (E) was 94.48± 25,24cm/s, the transmitrale velocity when atrial contraction (A) was 91.06 ±24,52cm/s and the average of E/A ratio was 1.13±0.43. In 43 cases (46.7%), the ratio was between 1 and 2; in 44 cases (47.8%) was less than 1 and in 3 cases it was more than 2. The average of DTE was 214.54 ±77,48ms. The average of IVRT was 93.57±20,86ms. The abnormalities of diastolic function were found in 60.8% of cases, with relaxation disorder in 46.7% of cases and a restrictive profile from 6.5% of cases. On DTI mode, the average of (Ea) was 14, 23±4,18cm/s and (Sa) was 16.86±4,95cm/s. The E/Ea ratio was 7.24±2.81 on average. The report dAp – dAm was calculated for patients with E / Ea ratio between 8 and 15. Filling pressures were considered high in 11 cases (12%). Patients with high LV filling pressure had reports E / Ea significantly higher than patients with normal LV filling pressures. They had a dilated left atrium with a significantly higher LAS.

Chronic hemodialysis patients represent a particular profile of patients with variable volume expansion. Thus, a slight hyper- blood volume may cause pulmonary congestion and acute pulmonary edema. On the other hand, the ultrafiltration per- dialysis may induce a significant decrease in filling pressures and cause hypotension.
