Background: Cardiovascular complications, particularly left ventricular hypertrophy (LVH), are
the leading cause of morbidity and mortality in chronic haemodialysis patients. Study objective:
describing the LVH prevalence in our population and determining its risk factors. Patients and
Methods: We adopted a multicentric analytical prospective study carried out in both the
nephrology, haemodialysis and kidney transplant department, and in the cardiology department of
the Marrakech University Hospital Centre. We selected chronic haemodialysis patients that
underwent thrice-weekly sessions of 4 hours and with a long-standing haemodialysis exceeding 9
months. Patients received a trans-thoracic echocardiogram 24 hours before and after the
haemodialysis session by the same operator. Results: Our study concerned 40 patients. The age
average is of 41.05 ± 18.8 years old. Seniority in haemodialysis is of 6.9 ± 6.17 years. Initial
nephropathy was diabetic in 12.5% of cases. 72.5% cases had anaemia. 70% of patients had
secondary hyperparathyroidism. 67.5% cases exhibited LVH. The interventricular septum thickness
in diastole was averaging 12.92 ± 2.66 mm and 10.8 ± 2.5 mm before and after the haemodialysis
session respectively. The posterior wall thickness in diastole was of 12.07 ± 2.2 mm before the
haemodialysis session, and 10.2 ± 2.4 mm after it. Conclusion: Our study shows a high LVH
prevalence. The LVH risk factors identified are anemia, high blood pressure, and
hyperparathyroidism.
