Cardiorenal Syndrome in Patients on Renal Replacement Therapy
In this chapter authors discusses cardiorenal relationships in patients with renal replacement therapy (RRT) which are considered as a separate type of cardiorenal syndrome (CRS). Frequency and severity of CRS in patients on dialysis are correlated with quantity of years of the dialysis treatment; depend on quality of dialysis regimen and level of residual renal function. RRT-associated cardiac pathology are including left ventricular hypertrophy, ischemic cardiomyopathy, congestive heart failure, coronary atherosclerosis and calcinosis, severe arrhythmias. The article analyzes role of malnutrition and dialysis-induced cachexia, bio-incompatibility of dialysis membranes, oxidative stress and inflammation, arterio-venous fistula, decrease of residual renal function in the development of dialysis-induced CRS. The review examines the mechanisms of progressive myocardial ischemia induced by dialysis: myocardial stunning, hemodialysis-induced hypotension, uremic small vessel disease. Prevention of dialysis-induced CRS includes a choice of the optimal RRT method (peritoneal dialysis or hemodialysis), соntrol of dialysis regimen, residual renal function, biocompatibility of membrane, inflammatory markers, body mass index, serum level albumin, phosphate, calcium, parathyroid hormone, fibroblast growth factor-23. Electrocardiogram, ultrasonic monitoring and coronarography reveals indications for соnservative cardioprotective therapy and angioplasty interventions, including coronary artery bypass surgery and cardiac pacemaker implantation, in patients with dialysis-induced CRS.
