Risk factors for left ventricular disorders in chronic haemodialysis patients

الملخص EN

Background : cardiovascular diseases are highly prevalent in patients with chronic kidney disease and represent the major hazard for mortality in this population , anomalies of left ventricular structure and function are very frequent and shows negative impact on cardiovascular prognosis.

Objective : to study left ventricular disorders in patients with chronic renal failure on haemodialysis program including left ventricular dysfunction, hypertrophy and dilatation and their relation with risk factors.

Methods : 62 patients with end stage renal failure on dialysis were studied by echocardiography, patients were divided into 4 groups G1 with normal echo, G2 left ventricular dysfunction, G3 left ventricular hypertrophy, G4 left ventricular dilatation, risk factors including age, sex, duration of dialysis, hypertension, S.

calcium S.

albumin and hemoglobin were compared between G1 and G2, G3, G4.

Results : left Ventricular disorders occurred in 67.7 % (17 % left ventricular dysfunction , 63 % left ventricular hypertrophy and 27 % left ventricular dilatation), older age group, longer duration of dialysis, hypertension, hypocalcaemia, hypoalbuminemia and anemia were found to be significantly associated with left ventricular disorders.

Conclusion : left ventricular disorders are common in patients with end stage renal failure on haemodialysis and it is important to correct risk factors like hypertension, anemia and hypocalcaemia.
