ABSTRACT

A consensus conference on cardio-renal syndromes (CRS) was held in Venice Italy, in September 2008 under the auspices of the Acute Dialysis Quality Initiative (ADQI). The following topics were matter of discussion after a systematic literature review and the appraisal of the best available evidence: definition/classification system; epidemiology; diagnostic criteria and biomarkers; prevention/protection strategies; management and therapy. The umbrella term CRS was used to identify a disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction in the other organ. Different syndromes were identified and classified into five subtypes. Acute CRS (type 1): acute worsening of heart function (AHF-ACS) leading to kidney injury and/or dysfunction. Chronic cardio-renal syndrome (type 2): chronic abnormalities in heart function (CHF-CHD) leading to kidney injury and/or dysfunction. Acute reno-cardiac syndrome (type 3): acute worsening of kidney function (AKI) leading to heart injury and/or dysfunction. Chronic reno-cardiac syndrome (type 4): chronic kidney disease leading to heart injury, disease, and/or dysfunction. Secondary CRS (type 5): systemic conditions leading to simultaneous injury and/or dysfunction of heart and kidney. Consensus statements concerning epidemiology, diagnosis, prevention, and management strategies are discussed in the paper for each of the syndromes.

    • "Patients with acute heart failure (HF) often develop acute worsening renal function (WRF) in the course of the disease. Their condition is then called acute cardiorenal syndrome (CRS) [1]. In this review, we have limited the discussion to the cardiorenal syndrome of type 1. Managing patients with HF is already challenging, but the presence of associated WRF can greatly increase mortality and morbidity [2]. "

    ABSTRACT: Acute cardiorenal syndrome (CRS) corresponds to an association of acute heart failure and a worsening of renal function. The detection of acute kidney injury (AKI) unfortunately occurs at a late stage of CRS, leading to an increased mortality of the patients. In this review, we described the pathophysiology of CRS and discussed the potential interest of biochemical biomarkers (namely creatinine, cystatin C, NGAL, KIM-1, fatty acid binding protein, Nacetyl-β-D-glucosaminidase and IL-18) that could potentially help to detect AKI earlier and thus reduce the morbi-mortality of the patients suffering from CRS.

    • "Impaired renal function is associated with worse clinical outcomes in patients with myocardial infarction, heart failure, and left ventricular systolic dysfunction [5] [6]. Syndromes describing the interaction between heart and kidney have been defined as cardiorenal syndromes to indicate the bidirectional nature of the various syndromes [1]. The incidence of the cardiorenal syndrome has increased due to the enhanced longevity of the population. "

    ABSTRACT: Sudden cardiac death continues to be a major public health problem. Ventricular arrhythmia is a main cause of sudden cardiac death. The present review addresses the links between renal function tests, several laboratory markers, and ventricular arrhythmia risk in patients with renal disease, undergoing or not hemodialysis or renal transplant, focusing on recent clinical studies. Therapy of hypokalemia, hypocalcemia, and hypomagnesemia should be an emergency and performed simultaneously under electrocardiographic monitoring in patients with renal failure. Serum phosphates and iron, PTH level, renal function, hemoglobin and hematocrit, pH, inflammatory markers, proteinuria and microalbuminuria, and osmolarity should be monitored, besides standard 12-lead ECG, in order to prevent ventricular arrhythmia and sudden cardiac death.

    • "Conversely, kidney disease is independently associated with increased cardiovascular morbidity and mortality. The clinical manifestation of the bidirectional interaction between the heart and kidneys is called CRS.[12] In the CRS, heart failure leads to kidney dysfunction and/or vice versa through numerous pathways of interaction between the heart and kidney.

    ABSTRACT: Background: Cystatin C (Cys C) has been implicated as a prognostic marker in cardiovascular disease. The aim of this study was to evaluate the value of Cys C as a marker of acute kidney injury (AKI) in acute heart failure (AHF), the impact of Cys C and N-terminal probrain natriuretic peptides (NT-proBNP) on in-hospital and 12 months mortality were also investigated. Materials and Methods: A total of 162 patients with AHF were enrolled. NT-proBNP, Cys C, serum creatinine (Scr), blood urea nitrogen (BUN) and parameters of echocardiography were measured for analyze. The in-hospital and 12 months mortality was analyzed. Results: There was 28 (17%) of all AHF patients with AKI. Compared with no-AKI patients, the levels of Cys C (1.51 ± 0.34 vs. 1.32 ± 0.29, P = 0.003) and NT-proBNP (8163.87 ± 898.06 vs. 5922.45 ± 576.73, P = 0.001) were higher in AKI patients. Higher levels of NT-proBNP (odds ratio (OR) = 1.92, 95% confidence interval (CI): 2.19-10.98, P = 0.018, OR = 4.31, 95% CI: 2.35-9.82, P = 0.002, respectively) and Cys C (OR = 1.48, 95% CI: 1.75-4.16, P = 0.027, OR = 2.72, 95% CI: 1.92-4.28, P = 0.017, respectively) were independent association with the in-hospital and 12 months mortality. Cys C was positively correlated with NT-proBNP (r = 0.87, P < 0.001). Combining tertiles of Cys C and NT-proBNP improved risk stratification further. Compared with patients without AKIcysC, patients with AKIcysC was associated with higher in-hospital (7/28 vs. 10/134, P = 0.002) and 12-month mortality (13/28 vs. 32/134, P = 0.001). Conclusion: Cys C was not only a promising risk marker in patients hospitalized for AHF, but also an independent predictor of 12-month mortality. Combining tertiles of Cys C and NT-proBNP could be used to distinguish the mortality risk identification of patients with AHF. AKI was an independent predictor of in-hospital and 12-month mortality.
