Spectrum of echocardiographic abnormalities in end-stage renal disease patients undergoing hemodialysis

الملخص EN

Background : cardiovascular disease is the most common cause of mortality in patients with end-stage renal disease.

Determining the spectrum of echocardiographic abnormalities in these patients can help the prevention of mortality in this group of chronically ill patients.

ةethods : 123 adult patients with chronic renal failure who underwent hemodialysis and echocardiography during February till November 2006 were enrolled.

Complete 2-D, M-mode, Doppler and color Doppler study were performed by a single operator for each patient and the abnormalities were recorded.

Results : the mean age was 38.3 + 13 and 61.5 % were female.

The mean cardiac dimensions were right ventricular diastolic dimension : 1.89 + 0.05 cm, inter-ventricular septal dimension: 1.3 + 1.23 cm, end diastolic dimension : 6,1 + 6,.

cm, end systolic dimension : 3.84 + 2.5 cm, ejection fraction: 59.2 + 11 %, left ventricular mass : 238 + 90 gr.

The prevalence of LV systolic dysfunction (EF < 50 %) was 20.3 %, volvuli regurgitation > mild, mitral regurgitation : 25.8 % aortic regurgitation : 24.4 %, and tricuspid regurgitation : 35.8 %.

Volvuli calcification was seen in14.5 % of the patients but no significant stenosis was noted.

The prevalence of pulmonary hypertension (SPAP > 30 mm Hg) was 14.7 % and that of pericardial effusion > mild was 14.7 %.

Cardiac ejection fraction was lower in patients requiring more hemodialysis sessions (p value < 0.036).

Conclusion : Echocardiographic abnormalities are very common in patients suffering from end-stage renal disease (ESRD), so periodic echocardiographic examination for diagnosis and treatment of cardiac abnormalities is highly recommended.
