[Cardiovascular risk factors in dialyzed patients]

Cardiovascular complications are the main cause of mortality and morbidity among patients on dialyses. The aim of the work was to assess the effect of the type of renal replacement therapy on the risk factors and cardiovascular complication in dialyzed patients. The studies were performed retrospectively on 90 hemodialyzed and 49 peritoneally dialyzed patients. Risk factors of cardiovascular diseases as well as serum lipids, complete blood count, serum albumin, fibrinogen, C-reactive protein, calcium, phosphates, PTH, systolic, diastolic, mean blood pressure, left ventricular hypertrophy. Hemodialyzed patients were more anemic, longer on renal replacement therapy, with higher albumin, phosphates, lower fibrinogen, cholesterol, LDL, triglycerides, calcium, systolic and diastolic blood pressure than peritoneally dialyzed patients. Left ventricular hypertrophy more frequently found in hemodialyzed patients than in peritoneally dialyzed patients. In peritoneally dialyzed patients glucose load into the peritoneum, dyslipidemia and hiperfibrinogenemia may further contribute at the cardiovascular complications. In hemodialyzed patients anemia, left ventricular hypertrophy and ischemic heart disease is more frequent than in peritoneally dialyzed patients.
