Renal Replacement Therapy in Cardiology Wards: Changing Trends in a Transitional Country

Abstract

The leading causes of death in patients with chronic kidney disease (CKD) are cardiovascular diseases, regardless of the stage of disease or method of renal replacement therapy. On the other hand, CKD is a major risk factor for cardiovascular complications after acute myocardial infarction, as well as for adverse outcome in patients with chronic heart failure. In the present study we prospectively followed-up nephrological interventions in cardiology wards in order to determine changes in indications, treatment possibilities and outcome of patients. All patients treated at cardiology ward of the Clinical Hospital Centre Zagreb and requiring renal replacement therapy from January 2003 to December 2009 were included in the investigation. Cardiology hospital unit (intensive care or regular hospital cardiology ward), age, gender, Sepsis-related Organ Failure Assessment (SOFA) score, indication for dialysis, primary diagnosis, vascular access, methods of treatment, number of treatments, prescribed and delivered dose of dialysis and outcome were recorded. Patients were followed up until death during hospitalization or discharge from the hospital. From January 2003 to December 2009, 251 patients had been hospitalized at different cardiology wards and required renal replacement therapy. Mean age was 64.95 years (range 22 to 97 years), and there were 27.8% female patients. 52.9% of patients were hospitalized in the coronary intensive care unit. SOFA score had increased during the observed period from average 6.5 in 2003 to 13.45 in 2009. Specific knowledge with close collaboration between nephrologists and cardiologists is needed to achieve optimal outcome in this complex condition.

Continuous Veno‐Venous Hemofiltration Improves Survival of Patients With Congestive Heart Failure and Cardiorenal Syndrome Compared to Slow Continuous Ultrafiltration

“…Acute heart failure (HF) is associated with high mortality and rehospitalization rates . Renal failure is a strong and independent risk factor for mortality in these patients .…”
