Cardiovascular (CV) death is the most frequent cause of dying in peritoneal dialysis (PD) patients. Risk factors include not only those that can be present in the general population, but also those related to the presence of end-stage renal disease (ESRD) and factors that are specific for PD modality. Hypertension is the most important general risk factor in PD patients, while obesity remains controversial. Inflammation, malnutrition, calcifications and probably endothelial dysfunction and oxidative stress are all CV risk factors present in ESRD that contribute to mortality in PD patients. Additional CV risk factors in PD are related to the glucose load, leading to increasing insulin resistance and a more atherogenic lipid profile. The presence of glucose degradation products in conventional dialysis solutions is mainly related to the development of peritoneal abnormalities, but not directly to cardiovascular disease. Loss of residual renal function and ultrafiltration failure promote overhydration, which is the most important PD-related risk factor for CV disease.
