Patients With Heart Failure

The combination of heart failure and renal failure is called cardiorenal syndrome. It is a stage of the cardiorenal continuum and, possibly, a small link of the cardiorenal-cerebral-metabolic axis. Despite the fact that the phrase “cardiorenal syndrome” and its five types have become a part of the medical lexicon, many aspects of this problem are still not clear. Cardiorenal syndrome can be diagnosed in 32-90.3% of patients with heart failure. Cardiorenal syndrome type 1 or 2 develops in most cases of heart failure: cardiorenal syndrome presents with the development ofchronic kidney disease in patients with chronic heart failure and acute kidney injury in patients with acute heart failure. Impaired renal function has an unfavorable prognostic value. It leads to an increase in the mortality of patients with heart failure. It is necessary to timely diagnose the presence of cardiorenal syndrome and take into account its presence when managing patients with heart failure. Further researches are needed on ways toprevent the development and prevent the progression of kidney damage in patients with heart failure, to which the efforts of the multidisciplinary team should be directed. The first part of this review examines the currently definition, classification, pathogenesis, epidemiology and prognosis of cardiorenal syndrome in patients with heart failure.

Refractory Heart Failure

Cardiorenal syndrome (CRS) type II is a serious condition in which chronic cardiac abnormalities cause worsening kidney function, leading to permanent chronic kidney damage. Management of CRS type II coupled with diuretic-resistant congestive heart failure (CHF) has been an issue of dispute. However, since the early 1990s, reports indicating the clinical usefulness of peritoneal dialysis (PD) as maintenance therapy for intractable CHF in this population have been accumulating. The present manuscript reviews the mechanisms by which kidney dysfunction develops within CHF, and then examines recent experiences of PD as chronic supportive therapy for intractable CRS type II, reviews the contributing mechanisms, and discusses the rationale for using PD as a new therapeutic approach in the nonuremic setting of CHF.

Background: Cardiorenal syndrome type 1 (CRS type 1) is characterized by a rapid worsening of cardiac function leading to acute kidney injury (AKI). Inflammation and oxidative stress seem to play a pivotal role in its pathophysiology. In this in vivo study, we examined the putative role of inflammation and humoral markers in the pathogenesis of the CRS type 1. Methods: We enrolled 53 patients with acute heart failure (AHF); 17 of them developed AKI (CRS type 1). The cause of AKI was presumed to be related to cardiac dysfunction after having excluded other causes. We assessed the plasma levels of proinflammatory cytokines (TNF-α, IL-6, IL-18, sICAM, RANTES, GMCSF), oxidative stress marker (myeloperoxidase, MPO), brain natriuretic peptide (BNP), and neutrophil gelatinase-associated lipocalin (NGAL) in AHF and CRS type 1 patients. Results: We observed a significant increase in IL-6, IL-18, and MPO levels in CRS type 1 group compared to AHF (p < 0.001). We found higher NGAL at admission in the CRS type 1 group compared to the AHF group (p = 0.008) and a positive correlation between NGAL and IL-6 (Spearman’s rho = 0.45, p = 0.003) and between IL-6 and BNP (Spearman’s rho = 0.43, p = 0.004). We observed lower hemoglobin levels in CRS type 1 patients compared to AHF patients (p < 0.05) and inverse correlation between hemoglobin and cytokines (IL-6: Spearman’s rho = –0.38, p = 0.005; IL-18: Spearman’s rho = –0.32, p = 0.02). Conclusion: Patients affected by CRS type 1 present increased levels of proinflammatory cytokines and oxidative stress markers, increased levels of tissue damage markers, and lower hemoglobin levels. All these factors may be implicated in the pathophysiology of CRS type 1 syndrome.

Cardiorenal syndrome type 1 (CRS-1) is an acute kidney injury (AKI) due to acute worsening of cardiac function. More than 20% of patients with acute heart failure develop AKI, and AKI predicts poor outcome. Although a number of potential pathways have been suggested as heart-kidney connectors which might drive the syndrome, there are significant barriers to investigation, such as a paucity of animal models, a lack of specific biomarkers, and an inconsistent temporal and causal relationship between changes in cardiac flow and development of renal dysfunction. Thus, mechanisms of heart-kidney interaction are still unclear, and there is no specific or effective therapy for CRS-1. This review, therefore, focuses on mitigating these challenges in the investigation of CRS-1. We review the available models and focus on mechanistic insights gained from those models. In particular, we focus on non-flow and endocrine mediators of CRS-1 such as heart-derived messengers which alter renal function and which may represent targetable pathways in this syndrome. As precise connectors of heart-kidney interaction remain unclear, the establishment of animal and relevant cell-culture models and further investigation are required.

Abstract Background The presence of acute kidney injury in the setting of acute heart failure is very common occurrence and was termed cardiorenal syndrome 1 (CRS1). In CRS1 the diagnosis of acute kidney damage is often delayed by creatinine and urine output following KDIGO standards (Kidney Disease Improving Global Outcomes). Cystatin C is one of the earliest markers of worsening renal function. We studied the value of plasma Cystatin C in the diagnosis of cardiorenal syndrome type 1. Purpose This study was aimed: (1) to decribe clinical, subclinical characteristics, prevalence of CRS1; (2) to evaluate the diagnostic efficacy of Cystatin C in diagnosis of CRS1. Materials and method There were 139 patients with acute heart failure or acute decompensated heart failure (ADHF) in the Department of cardiovascular resuscitation and Interventional cardiology at 115 Ho Chi Minh City People's Hospital from September 2018 to June 2019. This is a prospective cohort study. Results There were 48 cases (rate 34.5%) with CRS1, medium age 66.12±15.77, men accounted for 50.4%. The optimal cut-off Cystatin C for diagnosing CRS1 is &gt;1.81 mg/dl, AUC is 0.787 (95% CI 0.71–0.85, p&lt;0.001), sensitivity 75%, specificity 83.52%, positive predictive value 70.6%, negative predictive value 86.4%. Building the optimal regression model by the BMA (Bayesian Model Average) method with only one variable Cystatin C: Odds Ratio = ey, while y = −2.75 + 1.11x Cystatin C. Moreover, a nomogram with variable Cystatin C was designed to predict the likelihood of CRS1 with AUC 0.842. Ultimately, a confusion matrix was constructed to determine model accuracy 81.82%, sensitivity 78.26%, specificity 100%, positive predictive value 100%, negative predictive value 47.37%. Conclusions Cystatin C is quite good value in the diagnosis of CRS1 in patients with acute heart failure or ADHF. A predictive model based on Cystatin C may help early diagnose CRS1 in patients with acute heart failure or ADHF. FUNDunding Acknowledgement Type of funding sources: None.

Introduction: The presence of acute kidney injury in the setting of acute heart failure is very common occurrence and was termed cardiorenal syndrome 1 (CRS1). In CRS1 the diagnosis of acute kidney damage is often delayed by creatinine and urine output following KDIGO standards (Kidney Disease Improving Global Outcomes). Neutrophil gelatinase-associated lipocalin (NGAL) in the blood and urine is one of the earliest markers of acute kidney damage due to anemia or nephrotoxicity. Hypothesis: Plasma NGAL has good value in the diagnosis of cardiorenal syndrome type 1. Methods: There were 139 patients with acute heart failure or acute decompensated heart failure (ADHF) in the Department of cardiovascular resuscitation and Interventional cardiology at our hospital from September 2018 to June 2019. This is a prospective cohort study Results: There were 48 cases (rate 34.5%) with CRS1, medium age 66.12 ± 15.77, men accounted for 50.4%. The optimal cut-off for diagnosing NGAL CRS1 is > 353.23 ng/ml, AUC is 0.732 (95% CI 0.65-0.80, p <0.001), sensitivity 74.47%, specificity 68.48%, positive predictive value 54.7%, negative predictive value 84%. Building the optimal regression model by the BMA (Bayesian Model Average) method with 2 variables NGAL and creatinin day 1: Odds Ratio= e^y while y = - 2.39 + 0.0037 x NGAL + 0.17 x CreatininD1. Moreover, a nomogram with 2 variables NGAL and creatinin day 1 was designed to predict the likelihood of CRS1 with AUC 0.79 and validated on a testing set (consiting of 40 % of the data) by 10-cross-validation method with accuracy 79.82%. Ultimately, a confusion matrix was constructed to determine model accuracy 75.93%, sensitivity 76.74%, specificity 72.73%, positive predictive value 91.67%, negative predictive value 44.44%. Conclusions: Plasma NGAL is quite good value in the diagnosis of CRS1 in patients with acute heart failure or ADHF. A predictive model based on NGAL may help early diagnose CRS1 in patients with acute heart failure or ADHF.
