Impact of renal dysfunction on the management and outcome of acute heart failure: results from the French prospective, multicentre, DeFSSICA survey.

OBJECTIVES: Cardiorenal syndrome (CRS) is the combination of acute heart failure syndrome (AHF) and renal dysfunction (creatinine clearance (CrCl) ≤60 mL/min). Real-life data were used to compare the management and outcome of AHF with and without renal dysfunction. DESIGN: Prospective, multicentre. SETTING: Twenty-six academic, community and regional hospitals in France. PARTICIPANTS: 507 patients with AHF were assessed in two groups according to renal function: group 1 (patients with CRS (CrCl ≤60 mL/min): n=335) and group 2 (patients with AHF with normal renal function (CrCl >60 mL/min): n=172). RESULTS: Differences were observed (group 1 vs group 2) at admission for the incidence of chronic heart failure (56.42% vs 47.67%), use of furosemide (60.9% vs 52.91%), insulin (15.52% vs 9.3%) and amiodarone (14.33% vs 4.65%); additionally, more patients in group 1 carried a defibrillator (4.78% vs 0%), had ≥2 hospitalisations in the last year (15.52% vs 5.81%) and were under the care of a cardiologist (72.24% vs 61.63%). Clinical signs were broadly similar in each group. Brain-type natriuretic peptide (BNP) and BNP prohormone were higher in group 1 than group 2 (1157.5 vs 534 ng/L and 5120 vs 2513 ng/mL), and more patients in group 1 were positive for troponin (58.2% vs 44.19%), had cardiomegaly (51.04% vs 37.21%) and interstitial opacities (60.3% vs 47.67%). The only difference in emergency treatment was the use of nitrates, (higher in group 1 (21.9% vs 12.21%)). In-hospital mortality and the percentage of patients still hospitalised after 30 days were similar between groups, but the median stay was longer in group 1 (8 days vs 6 days). CONCLUSIONS: Renal impairment in AHF should not limit the use of loop diuretics and/or vasodilators, but early assessment of pulmonary congestion and close monitoring of the efficacy of conventional therapies is encouraged to allow rapid and appropriate implementation of alternative therapies if necessary.

A Call to Action to Develop Integrated Curricula in Cardiorenal Medicine.

With the adoption of the new definition and classification of cardiorenal syndrome (CRS) and its relevant subtypes, much attention has been placed on elucidating the mechanisms of heart and kidney interactions. The pathophysiologic pathways are of great interest by which acute heart failure may result in acute kidney injury (AKI; type 1), chronic heart failure accelerates the progression of chronic kidney disease (CKD; type 2), AKI provokes cardiac events (type 3), and CKD increases the risk and severity of cardiovascular disease (type 4). A remarkable interest has also been placed on the acute and chronic systemic conditions, such as sepsis and diabetes, that simultaneously affect heart and kidney function (type 5). Furthermore, the physiology of acute and chronic heart-kidney crosstalk is drawing attention to hemodynamics (fluids, pressures, flows, resistances, perfusion), physiochemical (electrolytes, pH, toxins) and biologic (inflammation, immune system activation, neurohormonal signals) processes. Common clinical scenarios call for recognition, knowledge, and skill in managing CRS. There is a clear need for medical and surgical specialists who are well versed in the pathophysiology and clinical manifestations that arise in the setting of CRS. With this editorial, we make a call to action to encourage universities, medical schools, and teaching hospitals to create a core curriculum for cardiorenal medicine to better equip the physicians of the future for these common, serious, and frequently fatal syndromes.

A close relationship between renal dysfunction and heart failure has been demonstrated with a huge impact on the patients outcomes. To describe the relationship, the term cardio-renal syndrome (CRS) has been increasingly used in recent years. Medical management of patients with CRS remains tremendously challenging. The integration of cardiology and nephrology communities providing with a more holistic and complete clinical presentation of patients seems to be a necessary strategy to treat this vulnerable population.

[Complementary treatment of acute heart failure in patients with diabetes, chronic obstructive pulmonary disease or anemia]. / Tratamiento complementario de la insuficiencia cardíaca aguda en el paciente con diabetes, enfermedad pulmonar obstructiva crónica o anemia.

Diabetes, chronic obstructive pulmonary disease (COPD) and anemia are comorbidities with a high prevalence and impact in heart failure (HF). The presence of these comorbidities considerably worsens the prognosis of HF. Diabetic patients have a higher likelihood of developing symptoms of HF and both the treatment of diabetes and that of acute HF are altered by the coexistence of both entities. The glycemic targets in patients with acute HF are not well-defined, but could show a U-shaped relationship. Stress hyperglycemia in non-diabetic patients with HF could also have a deleterious effect on the medium-term prognosis. The inter-relationship between COPD and HF hampers diagnosis due to the overlap between the symptoms and signs of both entities and complementary investigations. The treatment of acute HF is also altered by the presence of COPD. Anemia is highly prevalent and is often the direct cause of decompensated HF, the most common cause being iron deficiency anemia. Iron replacement therapy, specifically intravenous forms, has helped to improve the prognosis of acute HF.

Management of cardiorenal metabolic syndrome in diabetes mellitus: a phytotherapeutic perspective.

Cardiorenal syndrome (CRS) is a complex disease in which the heart and kidney are simultaneously affected and their deleterious declining functions are reinforced in a feedback cycle, with an accelerated progression. Although the coexistence of kidney and heart failure in the same individual carries an extremely bad prognosis, the exact cause of deterioration and the pathophysiological mechanisms underlying the initiation and maintenance of the interaction are complex, multifactorial in nature, and poorly understood. Current therapy includes diuretics, natriuretic hormones, aquaretics (arginine vasopressin antagonists), vasodilators, and inotropes. However, large numbers of patients still develop intractable disease. Moreover, the development of resistance to many standard therapies, such as diuretics and inotropes, has led to an increasing movement toward utilization and development of novel therapies. Herbal and traditional natural medicines may complement or provide an alternative to prevent or delay the progression of CRS. This review provides an analysis of the possible mechanisms and the therapeutic potential of phytotherapeutic medicines for the amelioration of the progression of CRS.

Tratamiento complementario de la insuficiencia cardíaca aguda en el paciente con diabetes, enfermedad pulmonar obstructiva crónica o anemia / Complementary treatment of acute heart failure in patients with diabetes, chronic obstructive pulmonary disease or anemia

La diabetes, la enfermedad pulmonar obstructiva crónica (EPOC) y la anemia son comorbilidades con elevada prevalencia e impacto en la insuficiencia cardíaca (IC). El pronóstico de la IC aguda empeora considerablemente ante la presencia de estas comorbilidades. Los pacientes diabéticos tienen mayor probabilidad de desarrollar clínica de IC, y tanto el tratamiento de la diabetes como el de la IC aguda se ven alterados ante la coexistencia de ambas entidades. Los objetivos glucémicos en pacientes con IC aguda no están bien definidos, pero podrían comportarse con una curva en U. La hiperglucemia de estrés en pacientes con IC aguda no diabéticos también tiene un efecto muy deletéreo en el pronóstico a medio plazo. La interrelación entre EPOC e IC aguda dificulta la fase diagnóstica al compartir síntomas, signos y estudios complementarios. El tratamiento de la IC aguda también se ve modulado por la presencia de la EPOC. La anemia es muy prevalente y, a menudo, es la causa directa de la descompensación de la IC, siendo la ferropenia la etiología más frecuente. Las terapias de reposición de hierro, concretamente la disposición de preparados de administración intravenosa, han contribuido a mejorar el pronóstico de la IC aguda (AU)
