CRS1 is present in 25% of patients admitted for heart failure. The objective of our study is to analyze the epidemiological, clinical, therapeutic profile and the risk and prognostic factors of these patients. Materials and Methods: We identified 120 patients with cardiorenal syndrome (CRS) over a one-year period to determine the prevalence and risk factors for developing CRS 1. We analyzed the clinical, biological, and evolutionary profiles of patients with CRS 1 and determined the risk factors for the occurrence of acute kidney injury (AKI) as well as the mortality factors in these patients. Résultats: The average age of our patients with CRS1 is 58 ± 9 years, with a sex ratio of 1.4. The average eGFR of our patients is 35 ± 6.5 ml/min/1.73m2. Diabetes was found in 17% of our patients and hypertension in 14%. The etiology of cardiac impairment is predominantly acute coronary syndrome (ACS), followed by rhythm disorders. Renally, all our patients have acute kidney injury (AKI), with 86% having functional acute renal failure and 14% having acute tubular necrosis. Therapeutically, 50% of our patients are on diuretics, 42% receive beta-blocker treatment, and RAAS blockers are used in 29% of cases. Renal replacement therapy (RRT) sessions were required in 13.8% of cases. In univariate analysis, male gender, tachyarrhythmia, and hypertension are associated with the early onset of acute kidney injury (AKI). The use of diuretics, anemia, and low left ventricular ejection fraction (LVEF) are linked to a higher risk of developing CRS 1 (p = 0.021, p = 0.037, p = 0.010 respectively). In multivariate analysis, advanced age is significantly associated with increased mortality risk in CRS 1 patients (p = 0.030), while beta-blocker use is considered a protective factor (p = 0.014). Conclusion: Our study identifies several key factors associated with outcomes in type 1 CRS. Male gender, tachyarrhythmia, and hypertension are linked to early-onset AKI. The use of diuretics and the presence of anemia increase the risk of developing CRS1. Advanced age is significantly associated with higher mortality rates. Conversely, the use of beta-blockers appears to be protective in this patient population. .展开更多

Recent studies suggest that congestion has the ability ofmodulating 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 ultrafltration, but it has also been used in patients with refractory heart failure and fuid overload to help optimize volume status. Several uncontrolled studies and case series have so far evaluated the role of PD in management of hypervolemia for patients with heart failure. They have generally reported favorable results in this setting. However, the data on the outcomes of patients with end-stage renal disease and concomitant heart failure is mixed, and the proposed theoretical advantages of PD might not translate into improvedclinical endpoints. Congestion is prevalent in this patient population and has a signifcant effect on their survival. As studies suggest that a significant subset of patients with end-stage renal disease who receive PD therapy are hypervolemic, suboptimal management of congestion could at least in part explain these conficting results. PD is a highly fexible therapeutic modality and the choice oftechniques, regimens, and solutions can affect its ability for optimization of fluid status. This article provides an overview of the currently available data on the role and clinical relevance of congestion in patients with cardiorenal syndrome and reviews potential options to enhance decongestion in these patients.展开更多

AHF is frequently accompanied by renal dysfunction, which is a strong, independent predictor for poor prognosis. Several hemodynamic and neurohormonal effects of vasodilators—including preload and afterload reduction, activation or inhibition of neurohormonal and inflammatory cascades—have the potential to modulate cardiorenal interaction and impact renal function. However, the effect of vasodilators on renal function in acute heart failure is often poorly described. In this review, we provide an overview of the known cardiorenal effects of traditional and novel vasodilators in patients with acute heart failure.展开更多

If this assumption were true,then mechanical extraction of fluid(i.e.,ultrafiltration therapy) would be expected to portend positive impact on renal hemodynamics and function through improvement in cardio-circulatory physiology and reduction in neurohormonal activation. However,currently available ultrafiltration trials,whether in acute heart failure(AHF) or in CRS,have so far failed to show any improvement in renal function; they have reported no impact or even observed adverse renal outcomes in this setting. Moreover,the presence or absence of renal dysfunction seems to affect the overall safety and efficacy of ultrafiltration therapy in AHF. This manuscript briefly reviews cardiorenal physiology in AHF and concludes that therapeutic options for CRS should not only target cardio-circulatory status of the patients,but they need to also have the ability of addressing the adverse homeostatic consequences of the associated decline in renal function. Peritoneal dialysis(PD) can be such an option for the chronic cases of CRS as it has been shown to provide efficient intracorporeal ultrafiltration and sodium extraction in volume overloaded patients while concurrently correcting the metabolic consequences of diminished renal function. Currently available trials on PD in heart failure have shown the safety and efficacy of this therapeutic modality for patients with chronic CRS and suggest that it could represent a pathophysiologically and conceptually relevant option in this setting.展开更多

AHF is frequently accompanied by renal dysfunction, which is a strong, independent predictor for poor prognosis. Several hemodynamic and neurohormonal effects of vasodilators—including preload and afterload reduction, activation or inhibition of neurohormonal and inflammatory cascades—have the potential to modulate cardiorenal interaction and impact renal function.

文摘The current models of cardiorenal syndrome(CRS) are mainly based on a cardiocentric approach; they assume that worsening renal function is an adverse consequence of the decline in cardiac function rather than a separate and independent pathologic phenomenon. If this assumption were true,then mechanical extraction of fluid(i.e.,ultrafiltration therapy) would be expected to portend positive impact on renal hemodynamics and function through improvement in cardio-circulatory physiology and reduction in neurohormonal activation. However,currently available ultrafiltration trials,whether in acute heart failure(AHF) or in CRS,have so far failed to show any improvement in renal function; they have reported no impact or even observed adverse renal outcomes in this setting. Moreover,the presence or absence of renal dysfunction seems to affect the overall safety and efficacy of ultrafiltration therapy in AHF. This manuscript briefly reviews cardiorenal physiology in AHF and concludes that therapeutic options for CRS should not only target cardio-circulatory status of the patients,but they need to also have the ability of addressing the adverse homeostatic consequences of the associated decline in renal function. Peritoneal dialysis(PD) can be such an option for the chronic cases of CRS as it has been shown to provide efficient intracorporeal ultrafiltration and sodium extraction in volume overloaded patients while concurrently correcting the metabolic consequences of diminished renal function. Currently available trials on PD in heart failure have shown the safety and efficacy of this therapeutic modality for patients with chronic CRS and suggest that it could represent a pathophysiologically and conceptually relevant option in this setting.
