D Salleck, S John
Patients in the intensive care unit often suffer from cardiorenal syndrome, which can have an important influence on the patient's outcome. The heart and kidney influence each other via organ crosstalk. We screened and evaluated current publications on cardiorenal syndromes and their therapy. A key role in the management of cardiorenal syndromes is renal decongestion via loop diuretics.

This study tested the hypothesis that extracorporeal shock wave (ECSW) treatment can improve ischemia-induced left ventricular (LV) dysfunction in mini-pig with co-existing chronic kidney disease (CKD). LV ischemia in mini-pigs was induced by applying an ameroid constrictor over mid-left anterior descending artery (LAD), while model of CKD was established by right nephrectomy with partial ligation of left renal arterioles 2 weeks before LAD constriction. Thirty mini-pigs were randomly divided into group 1 (sham-control), group 2 (LV-ischemia), group 3 (LV-ischemia + CKD), Group 4 [LV-ischemia + ECSW (applied 1200 shots at 0...

The interactions between heart and kidney are various and of clinical relevance. Worsening of one organ often influences the function of the other. With NYHA and KDIGO we have classification systems for heart and kidney failure and those should be used for cardiorenal systems as well. Furthermore there is a useful classification system for cardiorenal syndromes itself. Cardiorenal syndrome is a complex illness which should be treated by interdisciplinary medical teams. A key roll in pathophysiology is the renin-angiotensin-aldosteron-system (RAAS)...

Multi-organ dysfunction is seen in nearly 40-60% of all patients presenting with sepsis, including renal and cardiac dysfunction. Cardiorenal syndrome type-5 reflects concomitant cardiac and renal dysfunction secondary to a systemic condition that primarily affects both organs, such as sepsis. There are limited data on the etiology, pathogenesis and clinical implications of cardiorenal syndrome in sepsis. Cardiac dysfunction and injury can be measured with cardiac biomarkers, echocardiographic dysfunction, and hemodynamic parameters...

The cardiovascular (CV) and renal protection reported with empagliflozin in EMPA-REG OUTCOME is now confirmed with canagliflozin in CANVAS in patients with type 2 diabetes and high cardiovascular risk: similar and significant reductions in major CV events (-14 vs. -14%), in hospitalisations for heart failure (-35 vs. -33%) and in renal events (-39 vs. -40%). The greater reduction in CV mortality (-38 vs. - 13%) and all-cause mortality (-32 vs. -13%) in EMPA-REG OUTCOME than in CANVAS may be explained by the greater proportion of patients with CV disease (secondary prevention : 99 vs...

AIM: Decreased nephron count may result in lower glomerular filtration rate (GFR) and cardiorenal injury in the absence of compensatory hyperfunction. In this study, we aimed to evaluate long-term effects of 50% nephron loss on endothelial functions and cardiac morphology in nondonor nephrectomy patients. METHODS: This study comprised 26 patients (median age: 44 [37.5-50] years, male: 14) with unilateral nephrectomy and 25 healthy controls (median age: 47 [42-50] years, male: 9)...

INTRODUCTION: Cardiorenal syndrome (CRS) is common in acute heart failure (AHF), and is associated with dire prognosis. Levosimendan, a positive inotrope that also has diuretic effects, may improve patients' renal profile. Published results are conflicting. OBJECTIVES: We aimed to assess the incidence of CRS in AHF patients according to the inotrope used and to determine its predictors in order to identify patients who could benefit from the most renoprotective inotrope...

Epigenetics is defined as the heritable changes in gene expression patterns which are not directly encoded by modifications in the nucleotide DNA sequence of the genome, including higher order chromatin organization, DNA methylation, cytosine modifications, covalent histone tail modifications, and short non-coding RNA molecules. Recently, much attention has been paid to the role and the function of epigenetics and epimutations in the cellular and subcellular pathways and in the regulation of genes in the setting of both kidney and cardiovascular disease...

Cardiovascular events are the leading cause of death in patients with chronic kidney disease (CKD), although the pathological mechanisms are poorly understood. Here we longitudinally characterized left ventricle pathology in a 5/6 nephrectomy rat model of CKD and identify novel molecular mediators. Next-generation sequencing of left ventricle mRNA and microRNA (miRNA) was performed at physiologically distinct points in disease progression, identifying alterations in genes in numerous immune, lipid metabolism, and inflammatory pathways, as well as several miRNAs...

BACKGROUND: The cardiorenal syndrome (CRS) is a major health problem in our aging population. The term was introduced to cover disorders of the kidneys and heart, whereby dysfunction of one organ may induce dysfunction of the other. As the natural history of the CRS is mostly slow, hence difficult to explore in clinical trials, adequate animal models combining cardiovascular and renal disease are required. Therefore, we developed and characterized a usable model for CRS type 4, i.e. chronic kidney disease (CKD) causing cardiac dysfunction...

Despite the development of pharmacological inventions and new non-pharamacological techniques to prevent and treat HF, the mortality rate in patients with symptomatic HF remains high. To conquer these difficulties, the pathophysiology of HF should be considered within a wide range of views. Given the diverse mechanisms of HF pathophysiology, renal and cardiac functions have close and complementary interconnections. Recent studies suggest that communication between kidney and heart through bidirectional pathways causes significant pathological changes...

Congestion is an integral component of cardiorenal syndrome and portends an adverse impact on the outcomes. Recent studies suggest that congestion has the ability of modulating the interactions between the kidney and the heart in this setting. Peritoneal dialysis (PD) is a home-based therapeutic modality that is not only offered to patients with end-stage renal disease to provide solute clearance and ultrafiltration, but it has also been used in patients with refractory heart failure and fluid overload to help optimize volume status...

Heart and kidney failure continued to be of increasing prevalence in today's society, and their comorbidity has synergistic effect on the morbidity and mortality of patients. Cardiorenal syndrome (CRS) is a complex disease with multifactorial pathophysiology. Better understanding of this pathophysiological network is crucial for the successful intervention to prevent advancement of the disease process. One of the major factors in this process is neurohormonal activation, predominantly involving renin-angiotensin-aldosterone system (RAAS) and arginine vasopressin (AVP)...

Longstanding hypertension ultimately leads to heart failure (HF), and as a consequence most patients with HF have a history of hypertension. Conversely, absence of hypertension in middle age is associated with lower risks for incident HF across the remaining life course. Cardiac remodeling to a predominant pressure overload consists of diastolic dysfunction and concentric left ventricular (LV) hypertrophy. When pressure overload is sustained, diastolic dysfunction progresses, filling of the concentric remodeled LV decreases, and HF with preserved ejection fraction ensues...

Congestion represents the primary reason for hospitalization of patients with heart failure and is associated with adverse outcomes. Fluid overload has been shown to be inadequately addressed in a significant subset of these patients in part due to lack of robust, reliable, and readily available biomarkers for objective assessment and monitoring of therapy. Natriuretic peptides have long been used in this setting, often in conjunction with other assessment tools such as imaging studies. Patients presenting with concomitant cardiac and renal dysfunction represent a unique population with regard to congestion in that the interactions between the heart and the kidney can affect the utility and performance of biomarkers of fluid overload...

Takotsubo cardiomyopathy (TC) is a life-threatening syndrome with ambiguous pathophysiology. The interdependency between heart failure and kidney failure (KF) is well established, but the influence of KF on TC outcome is not known. This single-center cohort from January 2003 to September 2015 consisted of 114 consecutive patients with TC. They were divided into 2 groups according to the presence (n = 32, 29.6%) or absence (n = 76, 70.3%) of KF. The end point of this retrospective study was a composite of in-hospital events, all-cause mortality, rehospitalization due to heart failure, stroke, and recurrence of TC (mean follow-up: 5 years)...
