Código shock cardiogénico 2023. Documento de expertos para una organización multidisciplinaria que permita una atención de calidad / Cardiogenic shock code 2023. Expert document for a multidisciplinary organization that allows quality care

Pese a los esfuerzos realizados para mejorar la atención al shock cardiogénico (SC), incluyendo el desarrollo de dispositivos de asistencia circulatoria mecánica (ACM), su pronóstico continúa siendo desfavorable. En este contexto surgen iniciativas de código SC, basadas en proporcionar una asistencia rápida y de calidad a estos pacientes. Este documento multidisciplinario trata de justificar la necesidad de implantar el código SC, definiendo su estructura/organización, criterios de activación, flujo de pacientes según nivel asistencial e indicadores de calidad. Sus propósitos concretos son: a) presentar las peculiaridades de esta enfermedad y el aprendizaje del código infarto y de experiencias previas en SC; b) detallar las bases para el abordaje de estos pacientes, la estructura de los equipos, su logística, la elección del tipo de ACM y el momento de su implante, y c) abordar los desafíos para la implantación del código SC, como la singularidad del código SC pediátrico. Urge desarrollar una asistencia protocolizada, multidisciplinaria y centralizada en hospitales con gran volumen y experiencia que permita minimizar la inequidad en el acceso a la ACM y mejorar la supervivencia de estos enfermos. Solo el apoyo institucional y estructural de las distintas administraciones permitirá optimizar la atención al SC (AU)

Despite the efforts made to improve the care of cardiogenic shock (CS) patients, including the development of mechanical circulatory support (MCS), the prognosis of these patients continues to be poor. In this context, CS code initiatives arise, based on providing adequate, rapid, and quality care to these patients. In this multidisciplinary document we try to justify the need to implement the SC code, defining its structure/organization, activation criteria, patient flow according to care level, and quality indicators. Our specific purposes are: a) to present the peculiarities of this condition and the lessons of infarction code and previous experiences in CS; b) to detail the structure of the teams, their logistics and the bases for the management of these patients, the choice of the type of MCS, and the moment of its implantation, and c) to address challenges to SC code implementation, including the uniqueness of the pediatric SC code. There is an urgent need to develop protocolized, multidisciplinary, and centralized care in hospitals with a large volume and experience that will minimize inequity in access to the MCS and improve the survival of these patients. Only institutional and structural support from the different administrations will allow optimizing care for CS (AU)

Tendencias en el tratamiento del shock cardiogénico e impacto pronóstico del tipo de centros tratantes / Trends in cardiogenic shock management and prognostic impact of type of treating center

INTRODUCCIÓN Y OBJETIVOS: Las guías recomiendan centralizar la atención del shock cardiogénico (SC) en centros altamente especializados. El objetivo de este estudio fue evaluar la asociación entre las características de los centros tratantes y la mortalidad en el SC secundario a infarto de miocardio con elevación del segmento ST (IAMCEST). MÉTODOS: Se seleccionaron los episodios de alta con diagnóstico de SC-IAMCEST entre 2003-2015 del Conjunto Mínimo Básico de Datos del Sistema Nacional de Salud español. Los centros se clasificaron según disponibilidad de servicio de cardiología, laboratorio de hemodinámica, cirugía cardiaca y disponibilidad de Unidad de Cuidados Intensivos Cardiológicos (UCIC). La variable objetivo principal fue la mortalidad hospitalaria. RESULTADOS: Se identificaron 19.963 episodios. La edad media fue de 73,4±11,8 años. La proporción de pacientes tratados en hospitales con laboratorio de hemodinámica y cirugía cardiaca aumentó del 38,4% en 2005 al 52,9% en 2015; p <0,005). Las tasas de mortalidad bruta y ajustada por riesgo se redujeron progresivamente (del 82 al 67,1%, y del 82,7 al 66,8%, respectivamente, ambas p <0,001). La revascularización coronaria, tanto quirúgica como percutánea, se asoció de forma independiente con una menor mortalidad (OR = 0,29 y 0,25, p <0,001); La disponibilidad UCIC se asoció con menores tasas de mortalidad ajustadas (el 65,3±7,9% frente al 72±11,7%; p <0,001). CONCLUSIONES: La proporción de pacientes con SC-IAMCEST tratados en centros altamente especializados aumentó, mientras que la mortalidad disminuyó a lo largo del periodo de estudio. La revascularización y el ingreso en UCIC se asociaron con mejores resultados

INTRODUCTION AND OBJECTIVES: Current guidelines recommend centralizing the care of patients with cardiogenic shock in high-volume centers. The aim of this study was to assess the association between hospital characteristics, including the availability of an intensive cardiac care unit, and outcomes in patients with ST-segment elevation myocardial infarction (STEMI)-related cardiogenic shock (CS). METHODS: Discharge episodes with a diagnosis of STEMI-related CS between 2003 and 2015 were selected from the Minimum Data Set of the Spanish National Health System. Centers were classified according to the availability of a cardiology department, catheterization laboratory, cardiac surgery department, and intensive cardiac care unit. The main outcome measured was in-hospital mortality. RESULTS: A total of 19 963 episodes were identified. The mean age was 73.4±11.8 years. The proportion of patients with CS treated at hospitals with a catheterization laboratory and cardiac surgery department increased from 38.4% in 2005 to 52.9% in 2015 (P <.005). Crude- and risk-adjusted mortality rates decreased over time, from 82% to 67.1%, and from 82.7% to 66.8%, respectively (both P <.001). Coronary revascularization, either percutaneous or coronary artery bypass grafting, was independently associated with a lower mortality risk (OR, 0.29 and 0.25; both P <.001, respectively). Intensive cardiac care unit availability was associated with lower adjusted mortality rates (65.3%±7.9 vs 72±11.7; P <.001). CONCLUSIONS: The proportion of patients with STEMI-related CS treated at highly specialized centers increased while mortality decreased during the study period. Better outcomes were associated with the increased performance of revascularization procedures and access to intensive cardiac care units over time

Predictors of long-term renal function after conversion to proliferation signal inhibitors in long-term heart transplant recipients.

BACKGROUND: The purpose of this study was to evaluate the change in renal function and its determinants after replacement of calcineurin inhibitors with a proliferation signal inhibitor (sirolimus or everolimus) in long-term heart transplant recipients. METHODS: We studied 49 consecutive patients in whom a switch to a proliferation signal inhibitor was carried out 9 ± 4 years after transplantation. Evolutive glomerular filtration rate was assessed at a mean of 28 months after conversion by the simplified MDRD equation. RESULTS: Pre-conversion glomerular filtration rate (40 ± 22 ml/min/1.73 m(2)) remained stable at 1 year after conversion (41 ± 22 ml/min/1.73 m(2)), but decreased significantly by the end of follow-up (35 ± 22 ml/min/1.73 m(2); p = 0.008 and p = 0.002 vs pre-conversion and 1-year values, respectively). In a multivariate model, including age, time from transplantation to conversion, pre-conversion glomerular filtration rate, presence of diabetes and use of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) therapy, the rate of decline in renal function was related only to the presence of diabetes (p = 0.017) and inversely related to the use of ACEI/ARB therapy (p = 0.003). There were no significant differences with respect to age, time between transplantation and replacement and baseline glomerular filtration rate. CONCLUSION: In long-term heart transplant recipients, late substitution of a calcineurin inhibitor for a proliferation signal inhibitor does not preclude a decrease in renal function in the long-term setting. We identified the presence of diabetes as the main clinical predictor of renal function deterioration. In contrast, we found that the use of ACEI/ARB therapy could exert a protective effect.
