INTRODUCTION: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a common complication associated with increased morbidity and mortality. Tissue inhibitor metalloproteinases-2 • insulin-like growth factor-binding protein 7 (TIMP-2•IGFBP7) determines tubular stress markers, which may occur prior to tubular damage. Previous studies on the use of TIMP-2•IGFBP7 for the prediction of CSA-AKI showed divergent results. Therefore, this study aimed to explore the predictive value of TIMP-2•IGFBP7 measurements for the early detection of acute kidney injury (AKI) and short-term adverse outcomes after cardiac surgery...

BACKGROUND: Increased renal sodium avidity is a hallmark feature of the heart failure syndrome. SUMMARY: Increased renal sodium avidity refers to the inability of the kidneys to elicit potent natriuresis in response to sodium loading. This eventually causes congestion, which is a major contributor to hospital admissions and mortality in heart failure. KEY MESSAGES: Important novel concepts such as the renal tamponade hypothesis, accelerated nephron loss, and the role of hypochloremia, the sympathetic nervous system, inflammation, the lymphatic system, and interstitial sodium buffers are involved in the pathophysiology of renal sodium avidity...

BACKGROUND: Mineralocorticoid receptor plays an important pathophysiological role in cardiorenal diseases by causing inflammation and fibrosis. Mineralocorticoid receptor antagonists (MRAs) are well known in treating cardiovascular disease and diverse nephropathies. However, the first-generation MRA (spironolactone) and the second-generation MRA (eplerenone) remain underutilized because of the risk of inducing severe adverse events. As a selective non-steroidal MRA, finerenone is safer and more effective and improves cardiorenal outcomes in patients with chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM)...

The coexistence of heart and kidney diseases, also called cardiorenal syndrome, is increasingly common, leads to a significant impact on morbidity and mortality, and poses diagnostic and therapeutic difficulties. There is a risk-treatment paradox, such that patients with the highest risk are treated with lesser disease-modifying medical therapies. In this document, different scientific societies propose a practical approach to systematically address and optimize cardiorenal therapies and related comorbidities in chronic cardiorenal disease beyond congestion...

TThe vascular endothelium serves as a semi-selective permeable barrier as a conduit for transport of fluid, solutes and various cell populations between the vessel lumen and tissues. The endothelium thus has a dynamic role in the regulation of coagulation, immune system, lipid and electrolyte transport as well as neurohumoral influences on vascular tone and end-organ injury to tissues such as the heart and kidney. Within this framework, pharmacologic strategies for heart and kidney diseases including blood pressure, glycemic control and lipid reduction provide significant risk reduction yet certain populations are at risk for substantial residual risk for disease progression and treatment resistance and often have unwanted off-target effects leaving the need for adjunct, alternative targeted therapies...

BACKGROUND: Heart failure is frequently associated with kidney disease, and patients with kidney disease are at increased risk of heart failure. The co-occurrence of both entities not only significantly increases morbidity and mortality, but also complicates therapy. SUMMARY: Cardiorenal syndrome often requires a broad, comprehensive, and multidisciplinary approach. As a result, a need has arisen to create specialized cardiorenal units that allow for rigorous and personalized management of this condition...

INTRODUCTION: Heart failure (HF) progression according to changes in the serum chloride concentration ([sCl-]) was recently proposed as the 'chloride theory' for HF pathophysiology. The present study examined the association of neurohormones and renal Cl avidity to determine their contribution to acute HF and their involvement to the 'chloride theory'. METHODS: Data from 29 patients with acute HF (48% men; 80.3±12 years) were analyzed. Blood and urine samples were obtained before decongestive therapy...

INTRODUCTION: Albuminuria is prevalent in patients with chronic heart failure and is a risk factor for disease progression. However, its clinical meaning in acute heart failure remains elusive. This study analyzed the trajectory of urine albumin to creatinine ratio (UACR) between admission and discharge and its association with decongestion. METHODS: In this prospective observational study, 63 patients were enrolled. UACR, B-type natriuretic peptide (BNP), and clinical congestion score (CCS) were obtained at admission and discharge...

BACKGROUND: The maladaptive neurohormonal activation, an integral mechanism in the pathophysiology of heart failure (HF) and cardiorenal syndrome, has a profound impact on renal sodium handling. Congestion is the primary reason for hospitalization of patients with HF and the main target of therapy. As sodium is the main determinant of extracellular volume, the goal is to enhance urinary sodium excretion in order to address excess fluid. The interventions to increase natriuresis have conventionally been focused on distal nephron as the primary segment that counterbalances the effects of loop diuretics...
