Renal Functions and Prognosis Stratification in Chronic Heart Failure Patients and the Importance of Neutrophil Gelatinase-Associated Lipocalin
Background/Aims: The rate of incidence and prevalence of acute kidney injury is increasing due to an increased number of patients with heart failure. Therefore it is very pertinent to early detect the level of renal injuries and to make necessary heart failure predictions. Thus the aim of this study...

| description | Background/Aims: The rate of incidence and prevalence of acute kidney injury is increasing due to an increased number of patients with heart failure. Therefore it is very pertinent to early detect the level of renal injuries and to make necessary heart failure predictions. Thus the aim of this study is to determine renal functions and prognosis stratification in chronic heart failure patients and importance of Neutrophil Gelatinase-Associated Lipocalin (NGAL), an early diagnostic marker of acute kidney injury, as well as stratification of cardiovascular risk in heart failure patients. Methods: Data including age, gender, comorbidities and medical history of outpatients and hospitalized patients from Farmacology and NeuroHumoraL activation (FAR NHL) multicenter prospective registry comprising three Cardiological Centers in the Czech Republic were collected between 1st October 2014 and 30th November 2015. One-year follow-up data were collected in November 2016 in such a way that all patients had at least one-year data from the time of recruitment, but up to two years to the time of follow-up. One-year data were used for the whole set of patients while data up to 24 months were used with Kaplan-Meier‘s survival curves to analyse the patients‘ survival data. Blood samples were collected from the patients and basic parameters were evaluated in order to analyse Neutrophil gelatinase-associated lipocalin (NGAL) and plasma levels of N-terminal pro-brain natriuretic peptide (NT-ProBNP) using Lipocalin-2/NGAL Human ELISA kit (Bio Vendor, Czechia) and the Cobas E411 NT-proBNP Immunoassay kit (Roche Diagnostics, Indianapolis, IN, USA) respectively. Statistical analysis was further carried out to explain the level of significance of the evaluated parameters using Spearman Correlation, Mann Whitney or Kruskal-Wallis test and log-rank test. Results: Out of 547 patients from Farmacology and NeuroHumoraL activation (FAR NHL) multicenter prospective registry with available data on hospitalizations, mortality, biomarkers and one-year follow-up that were recorded, there were 439 males (80.3%) with a median age of 66 years. At least one-month stable patients with left ventricle ejection fraction (LV EF) under 50% were recorded. The etiology of heart failure was ischemic heart disease in 54%, dilated cardiomyopathy in 40% and others in 6%. 69% patients were in New York Heart Association functional class II. There were 76 events (13.9%; all-cause mortality, acute heart failure hospitalization, left ventricle assist device implantation and orthotopic heart transplant) in the first 365 days of follow-up. The area under the receiver operating characteristic curve was higher for NT-proBNP (0.77) than the creatinine (0.57), NGAL (0.55) or creatinine clearance (0.54). In multivariable analyses, NT-proBNP (P= 0.001) and NGAL (P = 0.004) were significant predictors of events. Subjects with NT-proBNP and NGAL above the cut off value (NT-proBNP 1,121 pg/ml, NGAL 80 ng/ml) survived without any event in 55.7%, subjects with NT-proBNP and NGAL under the cut off value survived without any event in 90.5%, after two years (P = 0.001). Conclusion: The findings of the study showed that NGAL associated with NT-proBNP was a stronger predictor of the primary endpoint than NGAL or NT-proBNP alone. The level of NGAL was rising in hypertension, ischemia, anemia, hypoalbuminemia, diabetes or arrhythmias. |
