ABSTRACT

INTRODUCTION: Patients with cardiovascular diseases are a group of increased risk of acute kidney injury (AKI). Mortality in this group of patients with AKI, especially treated in intensive care units, is very high. The aim of this study was to evaluate the clinical characteristic of patients with AKI complicated severe cardiovascular diseases. MATERIAL AND METHODS: Retrospective evaluation of 246 questionnaire of patients with AKI in the course of severe cardiovascular diseases treated in the wards of nephrological profile from the malopolska and podkarpackie voivodships in the years 2000-2011 was performed. RESULTS: The group of patients consisted of 157 men and 89 women, with mean age 67.9 ± 14.8 years. The most common cause of AKI were acute decompensated heart failure--24 (9.8%), chronic decompensated heart failure--94 (38.2%), cardiac arrest--29 (11.8%), myocardial infarction--48 (19.5%), CABG--12 (4.9%), cardiac valve implantation--14 (5.7), heart transplantation--4 (1.6%) and aortic aneurysm--21 (8.5%). Age distribution of patients with AKI revealed that most numerous group had 71-80 years. The most of patients (95.9%) with AKI were treated with hemodialysis. The mortality rate in the study group was very high (69.5%). Recovery of renal function was observed in 39 (27.3%) of patients. Signs of kidney disease before AKI was noted in 116 (47.2%) of patients. CONCLUSIONS: Patients with severe cardiovascular complications and AKI had high mortality rate instead of performed hemodialysis treatment.
