ABSTRACT

El tratamiento de los pacientes con insuficiencia cardiaca con fracción de eyección reducida (IC-FEr) con una combinación de 4 clases de fármacos se recomienda en las principales guías de práctica clínica internacionales. Sin embargo, no especifican cómo deben introducirse y ajustarse estos tratamientos. En consecuencia, muchos pacientes con IC-FEr no pasan a un régimen de tratamiento optimizado. El objetivo de esta revisión es proponer un algoritmo pragmático para optimizar el tratamiento, diseñado para que sea lo más fácil posible de aplicar en la práctica diaria. El primer objetivo es garantizar que las 4 clases de medicación recomendadas se inicien cuanto antes para establecer una terapia eficaz, incluso a dosis bajas. Esto se considera preferible a iniciar menos medicamentos a una dosis máxima. El segundo objetivo es garantizar que los intervalos entre la introducción de los medicamentos y entre los distintos pasos de titulación sean lo más breves posible, por la seguridad del paciente. Se hacen propuestas específicas para los pacientes de edad avanzada (> 75 años) frágiles, y para aquellos con trastornos del ritmo cardiaco. La aplicación de este algoritmo debería permitir alcanzar un protocolo de tratamiento óptimo en un plazo de 2 meses para la mayoría de los pacientes. Este debe ser nuestro objetivo en el tratamiento de la IC-FEr. (AU)


Major international practice guidelines recommend the use of a combination of 4 medication classes in the treatment of patients with heart failure with reduced ejection fraction (HFrEF) but do not specify how these treatments should be introduced and up-titrated. Consequently, many patients with HFrEF do not receive an optimized treatment regimen. This review proposes a pragmatic algorithm for treatment optimization designed to be easily applied in routine practice. The first goal is to ensure that all 4 recommended medication classes are initiated as early as possible to establish effective therapy, even at a low dose. This is considered preferable to starting fewer medications at a maximum dose. The second goal is to ensure that the intervals between the introduction of different medications and between different titration steps are as short as possible to ensure patient safety. Specific proposals are made for older patients (> 75 years) who are frail, and for those with cardiac rhythm disorders. Application of this algorithm should allow an optimal treatment protocol to be achieved within 2-months in most patients, which should the treatment goal in HFrEF. (AU)

ABSTRACT

BACKGROUND: Skeletal muscle failure and wasting are manifestations of sepsis in humans that leads to serious and prolonged complications. The authors investigated the role of the major proinflammatory and antiinflammatory pathways, namely the inducible isoforms cyclooxygenase (COX-2) and heme oxygenase (HO-1), and the ubiquitin proteolytic pathway in skeletal muscle of septic patients. METHODS: Protein expression was detected by Western blot techniques. Muscle biopsies were taken from two muscle groups, rectus abdominis and vastus lateralis, of septic and control patients. RESULTS: The study showed an increase in COX-2 and HO-1 proteins expression and an activation of the proteolytic ubiquitin pathway with a parallel increase in free ubiquitin and ubiquitinated proteins in skeletal muscle of septic but not of control patients. In addition, those patients who would die from septic shock expressed more COX-2 and HO-1 proteins in muscle biopsies than did those patients who would survive. CONCLUSIONS: This study showed a marked involvement of local proinflammatory and antiinflammatory pathways and, more importantly, demonstrated the existence of an active ubiquitin proteolytic pathway in skeletal muscle of septic patients. Activation of ubiquitin pathway could be involved in sepsis-related muscle catabolism and wasting.
