[Risk factors of death occurrence in patients with acute kidney injury in the course of severe cardio-vascular complications]. / Czynniki ryzyka zgonu u chorych z ostrym uszkodzeniem nerek w przebiegu ciezkich powiklan sercowo-naczyniowych.

INTRODUCTION: Acute kidney injury (AKI) is a frequent and serious complication in patients with cardiovascular disease. The aim of the study was to evaluate the risk of death in patients with AKI complicating severe cardiovascular diseases. MATERIAL AND METHODS: A retrospective analysis of 246 patients surveys (157 men and 89 women aged 67.9 ± 14.8 years) with AKI in the course of severe cardiovascular diseases, hospitalized in intensive care units and words of nephrological profile in years 2000-2011 were performed. RESULTS: The majority of patients (95.9%) with AKI required hemodialysis treatment. The mortality rate in the study group was high and amounted to 69.5% and the recovery of renal function was observed in 39 patients (27.3%). Kidney disease before the onset of AKI was observed in 116 patients (47.2%). Patients with arterial hypertension have more frequently oligoanuria (p = 0.001), needs more hemodialysis sessions (p = 0.029) and stay longer in hospital (p = 0.012). In multivariate analysis, the occurrence of death depend on such factors as: the lack of recovery of renal function, bleeding from gastrointestinal tract, urinary tract infections, and other infectious and noninfectious complications. CONCLUSIONS: No recovery of renal function and comorbidity while AKI in the course of severe cardiovascular diseases increase the risk of death.

[Clinical characteristic of patients with acute kidney injury complicated severe cardio-vascular diseases]. / Charakterystyka kliniczna pacjentów z ostrym uszkodzeniem nerek wiklajacym ciezkie schorzenia sercowo-naczyniowe.

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.
