Background: Maintenance haemodialysis (MHD) is the major form of renal replacement therapy in Nigeria, and may have a significant impact on cardiovascular (CV) and metabolic burden in chronic kidney disease (CKD) patients.
Methods: This is a prospective cohort study involving 40 CKD dialysis-naïve end-stage renal disease patients who were assessed at first contact before commencing dialysis and assessments repeated 3 months later while on MHD. Clinical, echocardiographic and biochemical indices were assessed on both occasions. We studied the impact of MHD on CV risk factors such as left ventricular hypertrophy, left ventricular ejection fraction (LVEF), high calcium-phosphate product, hypoalbuminaemia, anaemia and dyslipidaemia.
Results: The mean serum calcium-phosphate product, plasma total cholesterol, triglycerides and low-density lipoprotein cholesterol were significantly higher at baseline than at three months; while the mean haemoglobin, serum albumin and plasma high-density lipoprotein were significantly lower at baseline than at 3 months (P < 0.01). There was a significant difference in echocardiographic indices at baseline and at 3 months in CKD patients on MHD. Left ventricular mass and left ventricular mass index were significantly higher at baseline than at 3 months (P < 0.01); while LVEF was significantly lower at baseline than at 3 months (P < 0.01).
Conclusion: Our study showed statistically significant improvements in CV risk factors among CKD patients after 3 months on maintenance haemodialysis. Early and effective maintenance haemodialysis reduce CV risk factors in Nigerian CKD patients.
