RESUMO

BACKGROUND AND AIMS: Baseline cardiovascular toxicity risk stratification is critical in cardio-oncology. The Heart Failure Association (HFA) and International Cardio-Oncology Society (ICOS) score aims to assess this risk but lacks real-life validation. This study validates the HFA-ICOS score for anthracycline-induced cardiovascular toxicity. METHODS: Anthracycline-treated patients in the CARDIOTOX registry (NCT02039622) were stratified by the HFA-ICOS score. The primary endpoint was symptomatic or moderate to severe asymptomatic cancer therapy-related cardiac dysfunction (CTRCD), with all-cause mortality and cardiovascular mortality as secondary endpoints. RESULTS: The analysis included 1066 patients (mean age 54 ± 14 years; 81.9% women; 24.5% ≥65 years). According to the HFA-ICOS criteria, 571 patients (53.6%) were classified as low risk, 333 (31.2%) as moderate risk, 152 (14.3%) as high risk, and 10 (0.9%) as very high risk. Median follow-up was 54.8 months (interquartile range 24.6-81.8). A total of 197 patients (18.4%) died, and 718 (67.3%) developed CTRCD (symptomatic: n = 45; moderate to severe asymptomatic: n = 24; and mild asymptomatic: n = 649). Incidence rates of symptomatic or moderate to severe symptomatic CTRCD and all-cause mortality significantly increased with HFA-ICOS score [hazard ratio 28.74, 95% confidence interval (CI) 9.33-88.5; P < .001, and hazard ratio 7.43, 95% CI 3.21-17.2; P < .001) for very high-risk patients. The predictive model demonstrated good calibration (Brier score 0.04, 95% CI 0.03-0.05) and discrimination (area under the curve 0.78, 95% CI 0.70-0.82; Uno's C-statistic 0.78, 95% CI 0.71-0.84) for predicting symptomatic or severe/moderate asymptomatic CTRCD at 12 months. CONCLUSIONS: The HFA-ICOS score effectively categorizes patients by cardiovascular toxicity risk and demonstrates strong predictive ability for high-risk anthracycline-related cardiovascular toxicity and all-cause mortality.

RESUMO

Hemodynamic derangements are defining features of cardiogenic shock. Randomized clinical trials have examined the efficacy of various therapeutic interventions, from percutaneous coronary intervention to inotropes and mechanical circulatory support (MCS). However, hemodynamic management in cardiogenic shock has not been well-studied. This State-of-the-Art review will provide a framework for hemodynamic management in cardiogenic shock, including a description of the 4 therapeutic phases from initial 'Rescue' to 'Optimization', 'Stabilization' and 'de-Escalation or Exit therapy' (R-O-S-E), phenotyping and phenotype-guided tailoring of pharmacological and MCS support, to achieve hemodynamic and therapeutic goals. Finally, the premises that form the basis for clinical management and the hypotheses for randomized controlled trials will be discussed, with a view to the future direction of cardiogenic shock.

RESUMO

INTRODUCTION: Acquired amyloid neuropathy is an iatrogenic disease that appears years after a domino liver transplant. The objectives of our study are to analyze the efficacy and tolerability of tafamidis for the treatment of acquired amyloid neuropathy in domino liver transplant recipients. This post-authorization, prospective, longitudinal study included seven domino liver transplant recipients with acquired amyloid neuropathy who received treatment with tafamidis for 18 months. METHODS: The primary endpoints were the response rate, defined as those patients with an increase of < 2 points on the Neurological Impairment Score (NIS) from baseline, and the change in the NIS score from baseline. Secondary endpoints included the Quantitative Sensory Test, 10-m walk test, quality of life (Norfolk), and disability (Rasch-built Overall Disability Scale). As safety parameters, the evidence of graft rejection, changes in immunosuppressive trough levels and changes in antiviral and allogeneic cellular immunity before and 12 months after tafamidis treatment were also assessed. RESULTS: Six patients (85.7%) had responded at 18-months. Compared to baseline, we observed non-statistically significant improvement in mean NIS score at 6 months (- 2.54 points, CI - 5.92 to 0.84), 12 months (- 3.25 points; CI - 6.63 to 0.13), and 18 months (- 2.35 points; CI - 5.74 to 1.02). Changes in the Quantitative Sensory Test, 10-m walk tests and the quality of life and disability questionnaires were not statistically significant. The use of tafamidis did not induce relevant side effects or drug interactions. Also, no acute rejections events nor changes in functional adaptive immunity were observed. CONCLUSION: Our study supports the safety and tolerability of tafamidis for the treatment of acquired amyloid neuropathy in domino liver transplant recipients. Tafamidis shows promise as a useful treatment in the clinical management of these patients. Future randomized placebo-controlled clinical trials with longer follow-up durations are needed.

RESUMO

Introducción y objetivos: Los bloqueadores beta, inhibidores de la enzima de conversión de la angiotensina (IECA), antagonistas de los receptores de la angiotensina II (ARA-II) y antagonistas de receptores mineralocorticoides, disminuyen mortalidad y hospitalizaciones por insuficiencia cardiaca (IC) en pacientes con IC y fracción de eyección del ventrículo izquierdo reducida. Efecto dosis-dependiente. Se recomienda titulación cuidadosa. Sin embargo, las dosis subóptimas son habituales. Se comparó eficacia y seguridad de la titulación de fármacos enfermeras de IC frente a cardiólogos de IC. Métodos: ETIFIC fue un ensayo de no inferioridad, multicéntrico (20), abierto, controlado y aleatorizado. 320 pacientes hospitalizados con IC de debut, fracción de eyección reducida y New York Heart Association II-III. Sin contraindicación para bloqueadores beta, fueron aleatorizados 1:1, estratificados en bloques de 4 pacientes/hospital, 164 a titulación de enfermeras de IC frente a 156 cardiólogos de IC (analizados 144 frente a 145). El objetivo principal fue la dosis relativa media (% de dosis objetivo) de bloqueadores beta alcanzada a 4 meses. Los objetivos secundarios fueron: la dosis relativa media de IECA, ARA-II y antagonistas de receptores mineralocorticoides, variables asociadas, eventos adversos y resultados clínicos a 6 meses. Resultados: La dosis relativa media ± desviación estándar alcanzada por enfermeras de IC frente a cardiólogos de IC: bloqueadores beta 71,09 ± 31,49% frente a 56,29 ± 31,32%, diferencia 14,8% (IC95%, 7,5-22,1); p <0,001; IECA, 72,61 ± 29,80% frente a 56,13 ± 30,37%; p <0,001; ARA-II, 44,48 ± 33,47% frente a 43,51 ± 33,69%; p=0,93 y antagonistas de receptores mineralocorticoides 71 ± 32,12% frente a 70,47 ± 29,78%; p=0,86; media ± desviación estándar de visitas 6,41 ± 2,82 frente a 2,81 ± 1,58; p <0,001; n (%) efectos adversos 34 (23,6) frente a 30 (20,7), p=0,55; y hospitalizaciones por IC a 6 meses 1 (0,69) frente a 9 (5,51), p=0,01... (AU)


Introduction and objectives: Beta-blockers, angiotensin-converting enzyme inhibitors (ACE inhibitors), angiotensin-II-receptor-blockers (ARB), and mineralocorticoid-receptor antagonists decrease mortality and heart failure (HF) hospitalizations in HF patients with reduced left ventricular ejection fraction. The effect is dose-dependent. Careful titration is recommended. However, suboptimal doses are common in clinical practice. This study aimed to compare the safety and efficacy of dose titration of the aforementioned drugs by HF nurses vs HF cardiologists. Methods: ETIFIC was a multicenter (n=20) noninferiority randomized controlled open label trial. A total of 320 hospitalized patients with new-onset HF, reduced ejection fraction and New York Heart Association II-III, without beta-blocker contraindications were randomized 1:1 in blocks of 4 patients each stratified by hospital: 164 to HF nurse titration vs 156 to HF cardiologist titration (144 vs 145 analyzed). The primary endpoint was the beta-blocker mean relative dose (% of target dose) achieved at 4 months. Secondary endpoints included ACE inhibitors, ARB, and mineralocorticoid-receptor antagonists mean relative doses, associated variables, adverse events, and clinical outcomes at 6 months. Results: The mean±standard deviation relative doses achieved by HF nurses vs HF cardiologists were as follows: beta-blockers 71.09%±31.49% vs 56.29%±31.32%, with a difference of 14.8% (95%CI, 7.5-22.1), P <.001; ACE inhibitors 72.61%±29.80% vs 56.13%±30.37%, P <.001; ARB 44.48%±33.47% vs 43.51%±33.69%, P=.93; and mineralocorticoid-receptor antagonists 71%±32.12% vs 70.47%±29.78%, P=.86; mean±standard deviation visits were 6.41±2.82 vs 2.81±1.58, P <.001, while the number (%) of adverse events were 34 (23.6) vs 30 (20.7), P=.55; and at 6 months HF hospitalizations were 1 (0.69) vs 9 (5.51), P=.01...

RESUMO

La irrupción de la pandemia por COVID-19 está suponiendo un verdadero reto social y sanitario. Su rápida expansión hace que sean muchos los pacientes afectos que desarrollan clínica asociada, incluyendo síntomas cardiológicos. Los pacientes con afectación cardiaca son un grupo especialmente vulnerable, por su mayor riesgo de contagio y gravedad de la enfermedad. La insuficiencia cardiaca, incluyendo al trasplante cardiaco y las asistencias ventriculares, supone un grupo relevante dentro de los pacientes cardiológicos. Por ello, la Asociación de Insuficiencia Cardiaca de la Sociedad Española de Cardiología ha elaborado una serie de recomendaciones para el abordaje de estos pacientes, en los diferentes escenarios en los que se pueden encontrar: ambulatorio y hospitalizado, con y sin COVID-19


The outbreak of the COVID-19 pandemic is a real social and healthcare system challenge. Its rapid expansion implies that many affected patients develop associated symptoms, including cardiological symptoms. Patients with cardiological diseases are at increased risk of being infected and the severity of the disease. Heart failure, including heart transplantation and ventricular assist devices, is a relevant group within the cardiological patients. For this reason, the following text has been intended to give a series of recommendations for the management of these patients, in the different scenarios in which they can be found: outpatient and hospitalized, with and without COVID-19

RESUMO

INTRODUCCIÓN Y OBJETIVOS: Se presentan las características clínicas y los resultados de los trasplantes cardiacos realizados en España con la actualización correspondiente a 2019. MÉTODOS: Se describen las características clínicas y los resultados de los trasplantes cardiacos realizados en 2019, así como las tendencias de estos en el periodo 2010-2018. RESULTADOS: En 2019 se realizaron 300 trasplantes (8.794 desde 1984; 2.745 entre 2010 y 2019). Respecto a años previos, los cambios más llamativos son el descenso hasta el 38% de los trasplantes realizados en código urgente, y la consolidación en el cambio de asistencia circulatoria pretrasplante, con la práctica desaparición del balón de contrapulsación (0,7%), la estabilización del uso del oxigenador extracorpóreo de membrana (9,6%) y el aumento de los dispositivos de asistencia ventricular (29%). La supervivencia en el trienio 2016-2018 es similar a la del trienio 2013-2015 (p = 0,34), y ambas mejores que la del trienio 2010-2012 (p = 0,002 y p = 0,01 respectivamente). CONCLUSIONES: Se mantienen estables tanto la actividad del trasplante cardiaco en España como los resultados en supervivencia en los últimos 2 trienios. Hay una tendencia a realizar menos trasplantes urgentes, la mayoría con dispositivos de asistencia ventricular


INTRODUCTION AND OBJECTIVES: The present report describes the clinical characteristics and outcomes of heart transplants in Spain and updates the data to 2019. METHODS: We describe the clinical characteristics and outcomes of heart transplants performed in Spain in 2019, as well as trends in this procedure from 2010 to 2018. RESULTS: In 2019, 300 transplants were performed (8794 since 1984; 2745 between 2010 and 2019). Compared with previous years, the most notable findings were the decreasing rate of urgent transplants (38%), and the consolidation of the type of circulatory support prior to transplant, with an almost complete disappearance of counterpulsation balloon (0.7%), stabilization in the use of extracorporeal membrane oxygenation (9.6%), and an increase in the use of ventricular assist devices (29.0%). Survival from 2016 to 2018 was similar to that from 2013 to 2015 (P=.34). Survival in both these periods was better than that from 2010 to 2012 (P=.002 and P=.01, respectively). CONCLUSIONS: Heart transplant activity has remained stable during the last few years, as have outcomes (in terms of survival). There has been a trend to a lower rate of urgent transplants and to a higher use of ventricular assist devices prior to transplant

RESUMO

INTRODUCCIÓN Y OBJETIVOS: La insuficiencia cardiaca (IC) avanzada conlleva altas tasas de hospitalización y mortalidad. El estudio LION-HEART fue un ensayo clínico aleatorizado y controlado con placebo que evaluó la eficacia y la seguridad de la administración intravenosa de dosis intermitentes de levosimendán en pacientes ambulatorios con IC avanzada. El objetivo del presente estudio es realizar un análisis de costes para determinar si la menor tasa de hospitalizaciones por IC observada en pacientes tratados con levosimendán en el estudio LION-HEART puede generar ahorros para el Sistema Nacional de Salud, en comparación con la opción de no tratar a los pacientes con IC avanzada. MÉTODOS: Se realizó un modelo económico que incluyó las tasas de hospitalización por IC del estudio LION-HEART y los costes de hospitalización por IC y de adquisición y administración intravenosa de levosimendán. El horizonte temporal del análisis fue de 12 meses. Se realizaron 2 análisis, uno determinístico y otro probabilístico (simulación de Monte Carlo de segundo orden). RESULTADOS: Según el análisis determinístico, el ahorro total por cada paciente tratado con levosimendán ascendería a -698,48 euros. En el análisis probabilístico, el ahorro por paciente tratado con levosimendán sería de -849,94 (IC95%, 133,12 a -2.255,31) euros. La probabilidad de que se produzcan ahorros con levosimendán en comparación con la opción de no tratar sería del 94,8%. CONCLUSIONES: El tratamiento ambulatorio intermitente con levosimendán puede generar ahorros para el Sistema Nacional de Salud, en comparación con la opción de no tratar a los pacientes con IC avanzada


INTRODUCTION AND OBJECTIVES: Advanced heart failure (HF) leads to high hospitalization and mortality rates. The LION-HEART study was a randomized, placebo-controlled clinical trial that evaluated the safety and efficacy of intravenous administration of intermittent doses of levosimendan in outpatients with advanced HF. The aim of the present study was to perform a cost analysis to determine whether the lower rate of hospitalizations for HF, observed in patients treated with levosimendan in the LION-HEART study, can generate savings for the Spanish national health system compared with the option of not treating patients with advanced HF. METHODS: An economic model was used that included IC hospitalization rates from the LION-HEART study, the costs of hospitalization due to HF and those of the acquisition and intravenous administration of levosimendan. The time horizon of the analysis was 12 months. Two analyses were carried out, one deterministic and the other probabilistic (second-order Monte Carlo simulation). RESULTS: In the deterministic analysis, the total saving for each patient treated with levosimendan would amount to−€698.48. In the probabilistic analysis, the saving per patient treated with levosimendan would be−€849.94 (95%CI, €133.12 to−€2,255.31). The probability of savings with levosimendan compared with the no treatment option would be 94.8%. CONCLUSIONS: Intermittent ambulatory treatment with levosimendan can generate savings for the Spanish national health system compared with the option of not treating patients with advanced HF

RESUMO

Introducción y objetivos: Se presentan las características clínicas y los resultados de los trasplantes cardiacos realizados en España con la actualización correspondiente a 2018. Métodos: Registro prospectivo de todos los pacientes trasplantados en España entre 1984 y 2018, con un análisis específico de las tendencias temporales de las características clínicas y los resultados del periodo 2009-2017. Resultados: En 2018 se realizaron 321 trasplantes (8.494 desde 1984; 2.719 entre 2009 y 2018). Con respecto al año previo, en 2018 los trasplantes han aumentado un 52% en receptores menores de 16 años y un 42% en mayores de 60. En la última década, existen tendencias temporales significativas que apuntan a una mejor función renal previa al trasplante, más receptores diabéticos, más trasplantes urgentes, mayor uso de asistencia circulatoria antes del trasplante (particularmente con dispositivos de asistencia ventricular), mayor edad de los donantes, más donantes mujeres, más donantes fallecidos de accidente cerebrovascular y con parada cardiaca antes de la donación y menor tiempo de isquemia. Se observa una mejora significativa en la supervivencia en la última década, mediada fundamentalmente por una menor mortalidad por fallo primario del injerto. Conclusiones: La realización de trasplante cardiaco está aumentando en España, con una mejora progresiva de los resultados en términos de supervivencia


Introduction and objectives: The present report updates the clinical characteristics and outcomes of heart transplant in Spain to 2018. Methods: Prospective registry of all the heart transplants performed between 1984 and 2018 in Spain. Specifically, temporal trends in clinical characteristics and outcomes are described for the period from 2009 to 2017. Results: In 2018, 321 transplants were performed (8494 since 1984; 2719 between 2009 and 2018). Compared with the previous year, the number of transplants performed in 2018 rose by 52% in recipients younger than 16 years and by 42% in those older than 60 years. In the last decade, significant temporal trends were observed in recipient characteristics (better pretransplant renal function, higher rates of diabetes, more urgent transplants, and greater use of pretrasplant circulatory support, particularly ventricular assist devices), donor characteristics (higher donor age, more female donors, and higher frequencies of cerebrovascular cause of death and predonation cardiac arrest and lower ischemia time). Survival significantly improved in the last decade, mainly due to lower mortality due to primary graft failure. Conclusions: The number of heart transplants is increasing in Spain, with a progressive improvement in survival

RESUMO

Introducción y objetivos: Analizar el impacto del lactatos sérico en receptores de trasplante cardiaco urgente en asistencia circulatoria mecánica de corta duración preoperatoria. Métodos: Se realizó un subanálisis de un registro multicéntrico español basado en pacientes incluidos en «urgencia grado 0» para trasplante cardiaco con asistencia circulatoria mecánica preoperatoria de cortaduración entre 2010 y 2015. Se seleccionó a los receptores de trasplante con cifras preoperatorias de lactato conocidas. El desenlace principal fue la supervivencia 1año tras el trasplante. Resultados: Se estudió a 177 receptores de trasplante cardiaco urgente, de los que 90 necesitaron asistencia preoperatoria con oxigenador extracorpóreo de membrana venoarterial, 51 con asistencia ventricular izquierda y 36 con asistencia biventricular. De ellos, 44 (25%) presentaban hiperlactatemia antes del trasplante( 2mmol/l). En el análisis multivariable, la cifra de lactato sérico resultó predictora independiente de mortalidad tras el trasplante (cada 0,1 mmol/l, HR ajustada = 1,02; IC95%, 1,01-1,03; p = 0,007).La supervivencia estimada al año del trasplante cardiaco fue del 53,1% (IC95%, 45,3-60,9) en los pacientes con hiperlactactemia preoperatoria y el 75,6% (IC95%, 71,8-79,4)en los pacientes sin hiperlactatemia (HR ajustada = 1,94; IC95%, 1,04-3,63; p= 0,039). El impacto pronóstico de la hiperlactatemia fue significativo en los pacientes asistidos con oxigenador extracorpóreo de membrana venoarterial, pero no en aquellos con dispositivos de asistencia ventricular. Conclusiones: Los valores preoperatorios de ácido láctico son un potente factor pronóstico independiente en receptores de trasplante cardiaco urgente


Introduction and objectives: To study the prognostic value of serum lactate in patients under temporary preoperative mechanical circulatory support who underwent urgent heart transplant. Methods: We conducted asubanalysis of a Spanish multicenter registry recording data on patients under temporary mechanical circulatory support listed for highly urgent heart transplant from 2010 to 2015. Participants selected for the present study were those who received a transplant and who had known preoperative serum lactate levels. The main study outcome was 1-year survival after transplant. Results: A total of 177 heart transplant recipients were studied; preoperatively, 90 were supported on venoarterial extracorporeal membrane oxygenation, 51 on temporary left ventricular assist devices, and 36 on temporary biventricular assist devices. Preoperative hyperlactatemia( 2mmol/L) was present in 44 (25%) patients. On multivariable analysis, pretransplant serum lactate was identified as an independent predictor of 1-year posttransplant survival (adjusted HR per 0.1mmol/L, 1.02; 95%CI, 1.01-1.03; P=.007). One-year posttransplant survival was 53.1% (95%CI, 45.3-60.9) in patients with preoperative hyperlactatemia and 75.6% (95%CI, 71.8-79.4) in those without preoperative hyperlactatemia (adjusted HR, 1.94; 95%CI, 1.04-3.63; P=.039). Preoperative hyperlactatemia correlated with adverse outcomes in patient ssupported with extracorporeal membrane oxygenation, but not in patients supported on ventricular assist devices. Conclusions: Preoperative serum lactate is a strong independent predictor of worse outcomes in patients undergoing urgent heart transplant on short-term mechanical circulatory support

RESUMO

Introducción y objetivos: En España, el balón de contrapulsación intraaórtico (BCIA) se ha usado frecuentemente como puente al trasplante cardiaco (TxC) urgente. El propósito es analizar los resultados de esta estrategia. Métodos: Se realizó una revisión retrospectiva caso por caso de los registros clínicos de 281 pacientes adultos listados para TxC urgente asistidos con BCIA en 16 hospitales españoles entre 2010 y 2015. Se analizaron la supervivencia antes y después del trasplante y la incidencia de eventos adversos. Resultados: Se trasplantó a 194 pacientes (69%; IC95%, 63,3-74,4) y 20 (7,1%; IC95%, 4,4-10,8) fallecieron durante la asistencia, cuya duración media fue de 10,9+/-9,7 días. El BCIA se explantó antes de obtener un órgano a 32 pacientes (11,4%). En 35 pacientes (12,5%; IC95%, 8,8-16,9) se implantó un dispositivo de asistencia circulatoria mecánica completa. El tiempo en la lista de espera urgente se incrementó desde 5,9+/-6,3 días en 2010 hasta 15+/-11,7 días en 2015 (p=0,001). La supervivencia a 30 días y a 1 y 5 años tras el TxC fue del 88,1% (IC95%, 85,7-90,5), 76% (IC95%, 72,9-79,1) y 67,8% (IC95%, 63,7-71,9) respectivamente. La tasa de incidencia de eventos adversos mayores -disfunción del BCIA, ictus, hemorragia o infección- durante la asistencia fue de 26 (IC95%, 20,6-32,4) eventos/1.000 pacientes-día. La tasa de incidencia de explante del BCIA por complicaciones fue de 7,2 (IC95%, 4,5-10,8) casos/1.000 pacientes-día. Conclusiones: En el contexto de listas de espera cortas, el BCIA puede utilizarse como puente al TxC urgente con resultados aceptables. Esta estrategia conlleva una incidencia significativa de eventos adversos


Introduction and objectives: In Spain, intra-aortic balloon pump (IABP) has been used frequently as a bridge to urgent heart transplant (HT). We sought to analyze the clinical outcomes of this strategy. Methods: We conducted a case-by-case, retrospective review of clinical records of 281 adult patients listed for urgent HT under IABP support in 16 Spanish institutions from 2010 to 2015. Pre- and post-transplant survival and adverse clinical events were analyzed. Results: A total of 194 (69%, 95%CI, 63.3-74.4) patients were transplanted and 20 (7.1%, 95%CI, 4.4-10.8) died during a mean period of IABP support of 10.9+/-9.7 days. IABP support was withdrawn before an organ became available in 32 (11.4%) patients. Thirty-five (12.5%, 95%CI, 8.8-16.9) patients transitioned from IABP to full-support mechanical devices. Mean urgent waiting list time increased from 5.9+/-6.3 days in 2010 to 15+/-11.7 days in 2015 (P=.001). Post-transplant survival rates at 30-days, 1-year, and 5-years were 88.1% (95%CI, 85.7-90.5), 76% (95%CI, 72.9-79.1), and 67.8% (95%CI, 63.7-71.9), respectively. The incidence rate of major adverse clinical outcomes-device dysfunction, stroke, bleeding or infection-during IABP support was 26 (95%CI, 20.6-32.4) episodes per 1000 patient-days. The incidence rate of IABP explantation due to complications was 7.2 (95%CI, 4.5-10.8) cases per 1000 patient-days. Conclusions: In a setting of short waiting list times, IABP can be used to bridge candidates to urgent HT with acceptable postoperative results, but there were significant rates of adverse clinical events during support

RESUMO

Los pacientes con insuficiencia cardiaca avanzada tienen mal pronóstico y el trasplante cardiaco es actualmente la mejor opción de tratamiento disponible. Sin embargo, la escasez de donantes, los largos tiempos de espera y un número creciente de pacientes inestables han favorecido el desarrollo del soporte circulatorio mecánico. Esta revisión resume las indicaciones del trasplante cardiaco, cómo evaluar a los posibles candidatos, las estrategias actuales de inmunosupresión, cómo evaluar y tratar el rechazo, la profilaxis infecciosa y los resultados a corto y largo plazo. Respecto al soporte circulatorio mecánico, se diferencia entre las asistencias ventriculares de corto y largo plazo, así como las diferentes estrategias disponibles: puente hasta la decisión, recuperación, candidatura, trasplante y terapia de destino. Posteriormente se resumen las indicaciones, la valoración del riesgo previo al implante, el manejo de las complicaciones, especialmente de las asistencias de largo plazo y los resultados. Finalmente se plantean los retos futuros y cómo el uso generalizado de las asistencias ventriculares de largo plazo para pacientes con insuficiencia cardiaca avanzada solo será viable si se reducen sus complicaciones y costes (AU)


Patients with advanced heart failure have a poor prognosis and heart transplant is still the best treatment option. However, the scarcity of donors, long waiting times, and an increasing number of unstable patients have favored the development of mechanical circulatory support. This review summarizes the indications for heart transplant, candidate evaluation, current immunosuppression strategies, the evaluation and treatment of rejection, infectious prophylaxis, and short and long-term outcomes. Regarding mechanical circulatory support, we distinguish between short- and long-term support and the distinct strategies that can be used: bridge to decision, recovery, candidacy, transplant, and destination therapy. We then discuss indications, risk assessment, management of complications, especially with long-term support, and outcomes. Finally, we discuss future challenges and how the widespread use of long-term support for patients with advanced heart failure will only be viable if their complications and costs are reduced (AU)
