Aims After heart transplantation (HTx), increments in physical activity are strongly recommended. However, participation rates in exercise-based cardiac rehabilitation and engagement in physical activity (PA) are insufficient in many patients. Hence, this study aimed to explore the central factors and the interconnections among distinct types of motivation to exercise, PA, sedentary time, psychosomatic, diet and activity limitation characteristics in patients post-HTx. Methods and Results Cross-sectional study involving 133 patients post-HTx [79 men, mean age 57±13 years, mean time from transplantation 55±42 months] recruited from an outpatient clinic in Spain. The patients were asked to fill in questionnaires measuring self-reported PA, motivation to exercise, kinesiophobia, musculoskeletal pain, quality of sleep, depression, functional capacity, frailty, sarcopenia risk and diet quality. Two network structures were estimated: one network including PA and one network including sedentary time as nodes. The relative importance of each node in the network structures was determined using centrality analyses. According to the strength centrality index, functional capacity and identified regulation (sub-types of motivation to exercise) are the two most central nodes of the network (strength: z-score = 1.35-1.51). Strong and direct connections emerged between frailty and PA and between sarcopenia risk and sedentary time. Conclusion Functional capacity and autonomous motivation to exercise are the most promising targets of interventions to improve PA levels and sedentary time in patients post-HTx. Furthermore, frailty and sarcopenia risk were found to mediate the effect of several other factors on PA and sedentary time.

[Abstract] It is not clear to date whether a first admission in heart failure (HF) marks a worse evolution in patients not previously diagnosed with HF ("de novo HF") than those already diagnosed as outpatients ("acutely decompensated HF"). The aim of the study was to analyze whether survival in patients admitted for de novo HF differs from the survival in those admitted for a first episode of decompensation but with a previous diagnosis of HF. This study includes an analysis of 1,728 patients admitted for decompensated HF during 9 years. Readmissions and patients with left ventricular ejection fraction ≥50% were excluded (finally, 524 patients analyzed). We compared de novo HF (n = 186) in patients not diagnosed with HF, although their structural heart disease was defined, versus acutely decompensated HF (n = 338). The clinical profiles in both groups were similar. The de novo HF group more frequently presented with normal right ventricular function, with less presence of severe tricuspid regurgitation. The probability of survival was low in both groups. Thus, the median life in the de novo HF group was 2.1 years and in the acutely decompensated HF group, 3.5 years. There was a lower probability of long-term survival in the de novo HF group (p = 0.035). The variables associated with mortality were age (p

The outcomes of heart-lung transplant (HLT) are worse than those of heart transplant (HT) and lung transplant alone; this and the availability of mechanical assistance have meant that the indications for HLT have been changing. This study aims to analyze the evolution of indications for HLT in a country of 47 million inhabitants.We performed a retrospective observational study of all HLTs performed in Spain (performed in 2 centers) from 1990 to 2020. The total number of patients included was 1751 (HT 1673 and HLT 78). After clinical adjustment, overall survival was compared between the 2 groups. Seven etiological subgroups were considered within the HLT group: (1) cardiomyopathy with pulmonary hypertension (CM + PH);, (2) Eisenmenger syndrome, (3) congenital heart disease without Eisenmenger syndrome, (4) idiopathic pulmonary arterial hypertension (IPAH), (5) cystic fibrosis, (6) chronic obstructive pulmonary disease (COPD) and/or emphysema), and (7) diffuse interstitial lung disease.There were a large number of differences between patients with HLT vs HT. HLT had a 2.69-fold increased probability of death in the first year compared with HT. The indications for HLT have changed over the years. In the recent period the indications are mainly congenital heart disease and Eisenmenger syndrome, with some cases of CM + PH. Other indications for HLT have virtually disappeared, mainly lung diseases (IPAH, COPD, cystic fibrosis). Median survival was low in CM + PH (18 days), diffuse interstitial lung disease (29 days), and ischemic heart disease (114 days); intermediate in Eisenmenger syndrome (600 days); and longer in IPAH, COPD and/or emphysema, and cystic fibrosis.HLT is a procedure with high mortality. This and mechanical assists mean that the indications have changed over the years. Etiological analysis is of utmost interest to take advantage of organs and improve survival.

The age of heart transplant (HTx) donors and recipients is progressively increasing. The combination of donor-recipient ages has been shown to have prognostic implications. The objective of this study is to analyze survival in the first year and in the long-term based on the difference in age between donor and recipient of HTx.We performed a retrospective analysis of all consecutive HTxs performed in 1 center from 1987 to December 2021. Patients younger than 16 years, retransplants, and combined transplants were excluded. Three groups were considered according to the age of the donor and recipient: group 1: recipient and donor of the same age ± 10 years; group 2: donor10 years older than recipient; and group 3: donor10 years younger than recipient.A total of 841 HTxs were included (81% men, 31% urgent HTxs, donor mean (standard deviation) age 38.5 [12.3] years and recipient age 51.2 [12]). The most frequent group was group 3 with 476 patients (56%) followed by group 1 with 305 patients (36%). Figure 1 shows that long-term survival is similar in groups 1 and 2, being worse in group 3, P = .026. Mortality at the end of follow-up is 38.7% in group 1, 34.9% in group 2, and 71.9% in group 3 (P.0001). These differences occurred in the long-term without finding significant differences the first year after HTx. No differences were found in early graft failure between the 3 groups.Using donors of a different age from the recipient does not seem to have an impact on long-term survival, except when donors are used who are more than 10 years younger than the recipient, where survival is lower. This consolidates the concept that the use of elderly donors does not affect survival, allowing the pool of donors to be expanded.

Resumen Antecedentes y objetivos Las alteraciones del potasio constituyen un problema clinico de gran magnitud en la insuficiencia cardiaca (IC) descompensada. Este estudio pretende valorar las implicaciones pronosticas de la hipo e hiperpotasemia al ingreso por IC aguda en la mortalidad cardiovascular y reingresos hospitalarios. Material y metodo De enero de 2016 a junio de 2020 fueron ingresados 1.397 casos con diagnostico de IC aguda. Se excluyeron ingresos programados para estudio, terapias electivas y pacientes con fraccion de eyeccion del ventriculo izquierdo > 40%.

Introducción. La prevalencia de pacientes con asistencia ventricular ha aumentado debido al envejecimiento de la población, y al número limitado de órganos disponibles para donación. Estos pacientes pueden requerir atención médica de emergencia debido a complicaciones asociadas o no, a este soporte. El objetivo de este estudio es presentar unos algoritmos basados en el sistema ABCDE para la evaluación inicial y la reanimación de pacientes con asistencia ventricular. Material y métodos. Para la revisión bibliográfica, se realizó una búsqueda en las bases de datos Medline, a través de PubMed, CINAHL y CUIDEN con los términos cardiopulmonary resuscitation, consensus, emergency medical services, heart-assist devices. Se limitó la búsqueda a los últimos 5 años, y a los trabajos publicados en inglés o español. Resultados. Se obtuvieron 33 resultados, de los cuales se incluyeron 13 para revisión más exhaustiva. Los 20 restantes fueron descartados porque se referían a asistencias de corta duración. En base a los resultados obtenidos y a nuestra experiencia en el cuidado de estos pacientes, se han desarrollado tres algoritmos de actuación en emergencias: 1. Valoración inicial del paciente con un dispositivo de asistencia ventricular incluyendo vía aérea y respiración; 2. Solución de problemas del dispositivo de asistencia ventricular; 3. Valoración de la circulación. Discusión. Hemos visto que a nivel internacional hay protocolos estandarizados ante una emergencia en un paciente con dispositivo de asistencia ventricular. Esperamos que los algoritmos desarrollados se vayan implementando en la práctica, y que ayuden a que el manejo de las complicaciones sea más eficaz y eficiente.

Out-of-hospital emergency care in patients with ventricular assist devices Abstract Introduction. The prevalence of patients with mechanical circulatory support has increased due to population aging and the limited number of organs available for donation. These patients may require emergency medical attention due to complications associated or not with this support. This study aimed to present algorithms based on the ABCDE system for initial evaluation and resuscitation of adult patients with ventricular assist devices. Material and methods. For the bibliographic review, a search was carried out in the Medline databases, via PubMed, CINAHL, and CUIDEN with the terms cardiopulmonary resuscitation, consensus, emergency medical services, heart-assist devices. The search was limited to the last five years and papers published in English or Spanish. Results. Thirty-three results were obtained, of which 13 were included for a more comprehensive review. The remaining 20 were discarded as they referred to short-term assist devices. Based on the results obtained and our experience in caring for these patients, we developed three algorithms for emergency care: 1. Initial assessment of the patient with a ventricular assist device including airway and breathing; 2. ventricular assist device troubleshooting; 3. Ensuring adequate circulation to sustain life. Discussion. We have seen that, at an international level, there are standardized protocols for emergency care in patients with ventricular assist devices. We hope that the algorithms developed herein will be implemented in practice, helping to make the management of complications more effective and efficient.

Background Coronavirus disease 2019 (COVID-19) is a viral infectious disease caused by the severe acute respiratory syndrome coronavirus 2 virus that is affecting the entire world population. The objective of this study was to analyze the repercussion of the disease in a group of patients at risk such as heart transplant recipients. Methods From February 2020 to February 2021, heart transplant recipients diagnosed with COVID-19 were consecutively included. The total number of transplant recipients in outpatient follow-up at that time was 381. Three levels of infection were determined: group A: asymptomatic patients or with trivial symptoms without the need for hospital admission (6 patients); group B: patients admitted to the hospital for respiratory symptoms (12 patients); and group C: patients with severe symptoms and need for admission to the critical care unit (2 patients). At each risk level, medical performance was different: group A: close control, no therapeutic modification; group B: reduction of calcineurin inhibitor and substitution of mycophenolate mofetil for everolimus; group C: reduction of calcineurin inhibitor and withdrawal of mycophenolate mofetil. Results The prevalence of infection in the series was 5.2%. Most patients admitted had a pathologic chest x-ray with fever, cough, dyspnea, or vomiting. The change in immunosuppression performed in patients in group 2 was well tolerated and there was no graft rejection. Antiviral treatment was little used. However, boluses of steroids and some antibiotics were used frequently. The need for supplemental oxygen was 50% in group 2 and 100% in group 3. Conclusions A significant number of transplant recipients will be affected by COVID-19 (5.3%). Management of the infection will depend on the severity of the infection and must be based on a balance between reduction and adjustment of immunosuppression, strict control of the cardiologic situation, and treatment of the infection.

The most common symptom in heart failure (HF) is congestion, which can be refractory to diuretic treatment. To verify whether, in patients with advanced HF and diuretic resistance, subcutaneous furosemide or furosemide in an oral solution can improve the clinical-analytical status. From 2018 to 2020, 27 consecutive outpatients with diuretic resistance, not candidates for other alternatives, were recruited. Patients were treated either with subcutaneous furosemide in elastomeric pump (n: 10) or with oral solution (n: 17) for 5 days. The functional status (NYHA) improved with subcutaneous administration (predose: 3.8 ± 0.5 vs. postdose: 3.1 ± 0.7; p: 0.02) and oral solution (predose: 3.7 ± 0.3 vs. postdose: 2.5 ± 0.7; p: 0.0001). Weight loss was greater with the oral solution (predose: 85.5 ± 19.5 vs. postdose: 81.3 ± 18.8Kg; p: 0.0001) than subcutaneous (predose: 81.6 ± 15.9 vs. postdose: 80.4 ± 15.1kg; p: 0.16). Creatinine showed a non-significant increase in both groups. The number of hospital visits showed no difference between both options. The administration of furosemide, both subcutaneously by elastomeric pump or drinking the oral solution, is effective for the treatment of congestion in advanced HF refractory to diuretic treatment.

The aim of this study was to explore the readiness for physical activity (PA) and its related factors in patients with heart failure. This cross-sectional study included 163 patients with heart failure (mean age 66 +/- 16, 50% female). The ability to safely engage in PA was assessed with the PA Readiness Questionnaire (PAR-Q). Psychological readiness was measured using two questionnaires, namely: Exercise Self-efficacy Scale and the Motivation for PA and Exercise/Working Out. A multivariate analysis of covariance was conducted to test the effect of background variables on readiness for PA. 64% (n = 105) of patients reported not being able to safely engage in PA, 80% (n = 129) reported low self-efficacy, and 45% (n = 74) were extrinsically motivated indicating external factors drove their motivation. Factors that positively influenced the PA readiness included lower age (p < 0.01), being male (p < 0.01), being married (p < 0.01), having higher education (p < 0.01), being in NYHA-class I compared with II (p < 0.01), less time since diagnosis (p < 0.01), lower BMI (p = 0.02), and not suffering from COPD (p = 0.02). Prior to recommending exercise, assessment of safety to engage in PA along with self-efficacy and motivation in patients with heart failure is essential.

Heart transplant (HTx) recipients constitute a group vulnerable to COVID-19 infection. Vaccination has been a turning point in the evolution of the pandemic. The objective was to analyze a series of HTx recipients with COVID-19 prior to vaccination and post vaccination.Inclusion: All HTx recipients diagnosed with COVID-19 (February 2020 to April 2022).HTx younger than 16 years. They were subdivided into prevaccination period (February 2020 to February 2021) and postvaccination period (March 2021 to April 2022). They were classified into 3 groups according to severity. Group 1: mild symptoms without admission. Group 2: admission for nonsevere pneumonia. Group 3: severe pneumonia according to American Thoracic Society/Infectious Diseases Society of America criteria. The general therapeutic attitude before and after vaccination was similar in both groups.A total of 65 HTx recipients have had COVID-19 to date (10.7% of the 374 HTx recipients alive). In the prevaccination period, 22 HTx recipients presented the disease (Fig 1A): 27% in group 1; 59% were admitted for nonsevere pneumonia (group 2), with favorable evolution and a mean stay of 16 days; and 14% in group 3 (criteria for severe pneumonia), with 2 HTx recipients dying in this group. In the postvaccination period, 43 HTx recipients have presented COVID-19 (Fig 1B), 49% in group 1, 42% in group 2, and 9% in group 3. The hospital stay is slightly reduced to 15 days and 3 of the 4 patients in group 3 have died (mortality rate 7%).A significant number of HTx recipients have been affected by COVID-19, associating high mortality in severe forms both in the pre- and postvaccination period. In our series of patients, vaccination has reduced the percentage of hospitalization for nonsevere pneumonia slightly below the average hospitalization and mortality.

In advanced heart failure (HF), each hospitalization for decompensation is a vulnerable moment, and it requires optimizing pharmacologic treatment. This study aimed to analyze changes in the pharmacologic treatment of HF before admission (P), during hospitalization (H), and at discharge (D) of patients with decompensated advanced HF.We performed an ambispective, cross-sectional, noninterventional study conducted from January 2020 to June 2020. There were 252 consecutive patients admitted for decompensated advanced HF. The following were excluded: de novo HF cases, deceased patients, and scheduled admissions. Finally, 134 patients were analyzed, compared in 3 subgroups: pulmonary congestion (n = 90), systemic congestion (n = 31), and low output (n = 13).In the global analysis, an increase was detected in angiotensin receptor and neprilysin inhibitors (P: 9.7%, H: 16.4, D: 22.4%; P.02), beta blockers (P: 67.2%, H: 77.6%, D: 84.3%; P.004), mineralocorticoid receptor antagonists (P: 29.9%, H: 44.4%, D: 46.3%; P.01), loop diuretics (P: 70.1%, H: 99.3%, D: 95.5%; P.001), and nitrates (P: 6.0%, H: 22.4%, D: 9.7%; P.001). Pulmonary congestion was predominant with a significant increase in beta blockers (P: 61.1%, H: 77.8%, D: 88.9%; P.001) and loop diuretics (P: 64.4%, H: 100%, D: 100%; P.001); diuretics were increased in the systemic congestion group (P: 80.6%, H: 100%, D: 100%; P.002), and 22.6% required 3% hypertonic saline solution. In patients with low output, beta blockers and diuretics were withdrawn (P: 84.6%, H: 76.9%, D: 46.1%; P.08 and P: 84.6%, H: 92.3%, D: 61.5%; P.1 respectively), without variation in the other pharmacologic groups.In daily clinical practice, HF drugs are increased and optimized in decompensated HF with a pulmonary or systemic congestion profile. When the profile is low output, beta blockers and diuretics are reduced.

Background Noninvasive detection of primary graft dysfunction (PGD) remains a major challenge. SERCA2a plays an important role in cardiac homeostasis and its dysregulation has been associated with ventricular dysfunction and rejection. This study aimed to determine the potential utility of plasma levels of SERCA2a as a biomarker of PGD. Methods 135 plasma samples were collected from adult recipients 2-6 hours prior to heart transplantation (HT). Plasma concentrations of SERCA2a were determined using a specific sandwich enzyme-linked immunosorbent assay. Variables related to the recipient, the donor, and the periprocedural were collected in order to determine a multivariate predictive model of PGD. Results Levels of SERCA2a were decreased in patients who developed PGD (median 0.430 ng/mL [IQR 0.260 - 0.945] versus 0.830 ng/mL [IQR 0.582 - 1.052]; p = 0.001). Receiver operating characteristic (ROC) curve analysis revealed that SERCA2a discriminated between patients with and without PGD (AUC = 0.682, p = 0.001), and a cutoff point ≥ 0.60 ng/ml was a protective independent predictor of PGD (odds ratio 0.215 [p = 0.004]). Three independent predictors of PGD in this study were reduced levels of pre-HT SERCA2a, increased bilirubin levels, and short-term mechanical circulatory support bridge to transplantation. The analysis of the ROC curve of the model obtained a significant AUC 0.788, p = 0.0001. Conclusions Our findings suggest that assessment of SERCA2a plasma levels may improve risk prediction for the occurrence of PGD, and could be considered as a novel noninvasive biomarker in patients undergoing HT.

Resumen Introduccion y objetivos Algunos estudios indican que los parametros de strain por speckle-tracking pueden ser una alternativa no invasiva a la biopsia endomiocardica para excluir el rechazo celular agudo (RCA) moderado o grave (≥ 2 R) tras el trasplante cardiaco (TxC). En una cohorte inicial, unos puntos de corte del 15,5% para el strain longitudinal global del ventriculo izquierdo (SLGVI) y el 17% para el strain de pared libre del ventriculo derecho mostraron un valor predictivo negativo del 100% para excluir RCA ≥ 2 R. Nuestro objetivo es analizar la utilidad del strain y validar estos puntos de corte en una cohorte multicentrica prospectiva externa. Metodos Estudio multicentrico y prospectivo que incluyo a pacientes con seguimiento el primer ano tras el TC. Se compararon los resultados de biopsias electivas con ecocardiogramas realizados el mismo dia. Resultados Se incluyo a 99 pacientes y 501 pares de biopsias-ecocardiogramas. El RCA ≥ 2 R en las biopsias fue del 7,4%. El SLGVI y el strain longitudinal de pared libre del ventriculo derecho fueron menores durante los RCA ≥ 2 R en el analisis univariante. En el analisis multivariante, el SLGVI se asocio de manera independiente con el RCA ≥ 2 R. Los puntos de corte originales mostraron un valor predictivo negativo del 94,3% el RCA ≥ 2 R. Conclusiones Este estudio mantiene un alto valor predictivo negativo para excluir RCA ≥ 2 R tras el TxC y el SLGVI se asocio de manera independiente con el RCA ≥ 2 R. El strain y, principalmente, el SLGVI pueden ser de utilidad en el diagnostico y el tratamiento no invasivo del RCA.

Background Nucleocytoplasmic transport is a crucial process for cell function. Previous studies have observed alterations in different molecules involved in it, relating them to ventricular function. However, there are no published data evaluating possible differences in the expression of these molecules in heart transplantation (HT) recipients. Our objective is to evaluate whether its levels are related to the appearance of cellular rejection (CR) during the first year after HT. Methods A prospective clinical cohort that included patients undergoing HT between January 2017 and January 2019 (n = 46). Blood samples for the analysis of importin 5 (IMP5), nucleoporin 153 (Nup153); RAN-GTPaseAP1 (RanGAP1), and sarcoplasmic reticulum calcium ATPase (ATP-aseCaTransp) were collected approximately 2 months post-HT. The levels obtained were correlated with the incidence of at least moderate CR during the first year of follow-up. Results Results showed that 17.39% of the patients had at least moderate CR during the first year of follow-up. Higher levels of IMP5, Nup153, and RanGAP1 were observed in this group. This difference was statistically significant in the case of Nup153 and RanGAP1 (15.94 ± 14.00 vs 28.62 ± 23.61, P = .048; 21.95 ± 15.97 vs 40.90 ± 27.16, P = .026, respectively); there was an opposite trend in the ATP-aseCaTransp case. Conclusion Patients with at least a moderate degree of CR during follow-up showed higher serum levels of IMP5, Nup153, and RanGAP1. The prognostic usefulness of the determination of these biomarkers and whether their elevation during follow-up would facilitate early, noninvasive identification of patients with CR remains to be clarified.

Objective To determine whether physical activity enjoyment mediated the association between motivation and physical activity in patients with heart failure. Design and setting A cross-sectional study at the cardiology clinic in the university hospital in Valencia, Spain Subjects A total of 134 patients with heart failure. Main measurements Physical activity was assessed with the International Physical Activity Questionnaire, motivation was assessed with the Exercise Motivation Index and Physical Activity Enjoyment was assessed with the Physical Activity Enjoyment Scale. Analysis Mediation analysis using Hayes’ PROCESS macro (Model 4) for SPSS. Results The mean age of the sample was 70 ± 14 years, 47 patients were female (35%), and 87 patients were in New York Heart Association I/II (67%). A positive relationship was found between exercise motivation and physical activity ( t = 4.57, p Conclusions Physical activity enjoyment mediates the relationship between exercise motivation and physical activity in patients with heart failure. This means that even highly motivated heart failure patients may not be physically active if they do not enjoy the physical activity.

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.

Rationale and objectives Imaging is important in the diagnosis and follow-up of patients with heart failure (HF). Several thoracic radiological features have been described in these patients. The nodules with halo sign are very rarely reported in HF patients. This sign can appear in several diseases and a clinical context is essential for a final diagnosis. Materials and methods We present two immunocompetent patients with advanced HF waiting for cardiac transplantation showing multiple transient lung nodules with halo sign on preoperative chest CT. Results Our patients showed mild interstitial pulmonary edema and more interestingly multiple transient pulmonary nodules with halo sign. These nodules didn't coalesce, they even appear and disappear rapidly during worsening of pulmonary edema and showed thick halos. Nodules with halo sign are rarely reported in heart failure and considered focal pulmonary edema. Conclusion Nodules with halo sign in patients with advanced heart failure are a not usual finding that could not be the result of focal pulmonary edema, but of hemorrhage.

Currently, a high percentage of patients with congenital heart disease (CHD) reach adulthood. The consequence is that more and more patients will require a heart transplant (HTx) or heart-lung transplant (HLTx). The objective of the study was to analyze the evolution and temporary trend of the number of HTxs and HLTxs in patients with and without CHD.We performed a retrospective analysis of all HTxs and HTLxs from a Spanish transplant hospital. Retransplant and other combined transplants were excluded. HTx and HLTx were divided into 2 groups (CHD or non-CHD). The number of procedures of each modality was grouped in 5 years.A total of 930 HTxs were analyzed between 1987 and 2020; 36 were CHD (18 HTxs and 18 HLTxs). HTx and HLTx in CHD showed a growing progressive trend, probably because of the greater number of these patients who reach adulthood and finally develop advanced heart failure. HTx in patients without CHD showed a very high rise in the first decade, reaching the maximum peak around the year 2000, with a poststabilization trend or even progressive reduction in the number of procedures. HLTx in patients without CHD showed a marked ascent during the first decade with a peak around 2005 and subsequent significant decline in recent years practically in disuse, probably because of the possibility of circulatory assistance in the case of right ventricular failure.The number of HTxs and HLTxs in CHD has a progressive rise. The number of HTx in patients without CHD remains relatively stable. HLTx in patients without CHD shows a marked decrease.

Background: Tricuspid valve disease is the most frequent valvulopathy after heart transplantation (HTx). Evidence for the negative effect of post-transplant tricuspid regurgitation (TR) on survival is contradictory. The aim of this study was to analyze the causes of post-transplant TR and its effect on overall mortality.Methods: This is a retrospective observational study of all transplants performed in two Spanish centers (1009 patients) between 2000 and 2019. Of the total number of patients, 809 had no TR or mild TR and 200 had moderate or severe TR. The etiology of TR was analyzed in all cases.Results: The prevalence of moderate and severe TR was 19.8%. The risk of mortality was greater when TR was caused by early primary graft failure (PGF) or rejection (p < 0.05). TR incidence was related to etiology: incidence of PGF-induced TR was higher in the first period, while TR due to rejection and undefined causes occurred more frequently in three periods: in the first year, in the 10–14-year period following HTx, and in the long term (16–18 years). In the multivariable analysis, TR was significantly associated with mortality/retransplantation (HR:1.04, 95% CI:1.01–1.07, p:0.02).Conclusion: The development of TR after HTx is relatively frequent. The annual incidence depends on TR severity and etiology. The risk of mortality is greater in severe TR due to PGF or rejection.

Background: This study aimed to compare well-being and physical activity (PA) before and during COVID-19 confinement in older adults with heart failure (HF), to compare well-being and PA during COVID-19 confinement in octogenarians and non-octogenarians, and to explore well-being, social support, attention to symptoms, and assistance needs during confinement in this population. Methods: A mixed-methods design was performed. Well-being (Cantril Ladder of Life) and PA (International Physical Activity Questionnaire) were assessed. Semi-structured interviews were performed to assess the rest of the variables. Results: 120 participants were evaluated (74.16 ± 12.90 years; octogenarians = 44.16%, non-octogenarians = 55.83%). Both groups showed lower well-being and performed less PA during confinement than before (p < 0.001). Octogenarians reported lower well-being (p = 0.02), higher sedentary time (p = 0.03), and lower levels of moderate PA (p = 0.04) during confinement. Most individuals in the sample considered their well-being to have decreased during confinement, 30% reported decreased social support, 50% increased their attention to symptoms, and 60% were not satisfied with the assistance received. Octogenarians were more severely impacted during confinement than non-octogenarians in terms of well-being, attention to symptoms, and assistance needs. Conclusions: Well-being and PA decreased during confinement, although octogenarians were more affected than non-octogenarians. Remote monitoring strategies are needed in elders with HF to control health outcomes in critical periods, especially in octogenarians.

Aims Although physical activity (PA) and exercise are essential for patients with heart failure (HF), adherence to the recommended guidelines is low. Not much is known about the mediating effect of HF patients mental state with their readiness for PA and reported activity levels. The purpose of this study is to investigate the mediatory effect of depression on PA readiness (physical limitation and psychological readiness) and self-reported PA in patients with HF. Methods and results In this cross-sectional study, 163 New York Heart Association Class I and II HF patients, during their clinic visit, reported on their physical limitation (PAR-Q) and psychological readiness [self-efficacy (ESES) and motivation (RM 4-FM)] for PA, depression (HADS-D), and PA (s-IPAQ). Mediation analysis was performed to test the mediating effect of depression on PA readiness (physical limitation and psychological readiness) and self-reported PA following the steps described by Baron and Kenny (1986). Hierarchical regression models were tested for their effects. The Self-Efficacy Theory and Self-Determination theory provided the theoretical platform for the study. Depression completely mediated the effect of physical limitation (beta(dep) = 268.57; P < 0.0001) and partially mediated the effect of self-efficacy on PA (beta(dep) = 344.16; P < 0.0001). Both intrinsic (P < .0001) and extrinsic motivation (P < .0001) for PA had an independent and significant effect on PA, not mediated by depression. Conclusions Patients with HF should be screened for depression throughout the trajectory of the disease as it can impact their physical and psychological readiness to perform PA.

OBJECTIVES: In recent years, the percentage of heart transplantation (HT) with short/medium-term assistance devices has increased. This study aims at analyzing primary graft failure and in-hospital mortality according to the type of care. MATERIAL AND METHODS: From January 2013 to December 2017 all patients undergoing urgent HT with circulatory/ventricular assistance were retrospectively and consecutively recruited. Combined transplants, retransplantations and pediatric transplants were excluded. The sample was divided in 10 groups according to the type of shot/medium term assistance devices. RESULTS: A total of 53 patients were recruited, 79% men, average age 49 ± 13 years. 26 patients (51%) had mechanical ventilation at the time of the HT. Primary graft failure occurred in 20 patients (38.5%), whilst it was more frequent in patients assisted with ECMO (8 patients in group 1 (45%) and 7 in group 2 (54%), p 0.5). 14 deaths (27%) were registered, whereas a higher mortality was observed in the group assisted with ECMO (6 patients in group 1 (34%) and 4 in group 2 (31%), p 0.6). Mortality was 17% in the group of non-urgent Levitronix. CONCLUSIONS: Despite not showing statistical significance due to the low number of patients in some subgroups, hospital mortality was high in HT patients with circulatory assistance. A trend towards a higher incidence of primary graft failure and mortality in patients assisted with ECMO was observed. The direct implantation of a centrifugal pump as a bridge to urgent transplantation could identify a subgroup with a better prognosis.

BACKGROUND To analyze the relationship of the antigen carbohydrate 125 (CA125) biomarker with the cellular rejection of the heart graft during the first year after transplantation. METHODS Retrospective study of consecutive heart transplant (HTx) patients for 1.5 years. The total number of patients included in the study was 23 with a total of 103 follow-ups. In all patients, CA125 was determined before HTx and determined post-HTx in every follow-up. These were performed during months 1, 2, 4, 6, 9, and 12. Endomyocardial biopsy was performed in all revisions to assess the degree of graft rejection in the pathologic study. The biopsy results were grouped into 1. absence of rejection and 2. presence of some degree of rejection. RESULTS The mean pretransplant CA125 value presented a median of 120 U/mL with an interquartile range of 28.8 U/mL. One month after transplantation, the value was reduced by 20% and at 2 months by 81%. In subsequent reviews, plasma values were always between 10 and 20 U/mL. When comparing the values by periods and according to the presence or absence of rejection, no significant differences were found other than a slight elevation at the 6-month checkup (P = .03) but without clinical relevance, because the CA125 value was slightly higher in biopsy results without rejection. CONCLUSION The rapid reduction of CA125 corroborates its usefulness as a marker of congestion in heart failure. This biomarker is not useful for predicting rejection. However, in cases of very severe rejections that occurred with systemic congestion, it could be raised. It would be necessary to corroborate this hypothesis in a larger study with a higher number of severe rejections.

The purpose of this study was to analyze whether the level of IgA is related to right ventricular function and systemic congestion in patients with decompensated heart failure (HF) and reduced ejection fraction (EF).This was a consecutive prospective and observational study of hospitalized patients diagnosed with decompensated HF with reduced EF. The recruitment period lasted 2 months. In the first 24 hours after admission, clinical assessment, general laboratory tests, determination of HF biomarkers, IgA and echocardiographic study were performed. Patients were classified into 2 groups according to whether the plasma IgA level was lower (n = 11) or higher than 300 mg/dL (n = 12).Significant differences in IgA levels were found in the peripheral congestion variables (no congestion: 232, interquartile range [IQR], 125-310 mg/dL vs congestion: 429, IQR, 308-520 mg/dL; P = .03). There were also differences in echocardiographic parameters of right ventricular function, with a greater deterioration of right ventricular function in the group with higher IgA levels (P.05). There was a highly significant correlation between tricuspid annulus systolic excursion values and IgA levels (P = .004).In decompensated HF, patients with greater clinical congestion and echocardiographic parameters of right ventricular dysfunction have higher plasma IgA levels. This study is a preliminary experience that will help to establish the basis of the cardiointestinal syndrome as a clinical picture of systemic congestion in HF.

BACKGROUND The purpose of the study was to analyze postcardiac transplant complications in patients who received transplants with short-term mechanical ventricular assist devices and to compare complications according to the type of device. METHODS Ambispective and consecutive study of urgent heart transplants from 2015 to 2019. Pediatric transplants, retransplants, and combined transplants were excluded. A total of 45 patients were analyzed in 4 groups: (1) venoarterial extracorporeal membrane oxygenation (ECMO) implanted

Background Heart transplantation (HT) is the reference treatment for patients with terminal heart failure. In recent years there has been a progressive increase in HT procedures in patients who have a circulatory support (CS). Methods This is a retrospective single-center study of 293 consecutive patients who underwent HT from 2009 to 2018, analyzing the evolution of the 2 cohorts: patients with and without CS as a bridge to HT. Baseline and evolutionary clinical data collected following the usual follow-up protocol were recorded, including clinical events observed during the follow-up 1 year after the procedure. Results The subgroup of patients transplanted with CS showed a higher incidence of primary graft failure, frequent infection, and mortality. A tendency toward lower cardiac allograft vasculopathy was observed in this subgroup. Mechanical ventilation added to the CS resulted in a higher incidence of primary graft failure, infection, and renal dysfunction. The CS variable as a bridge to HT was shown to be predictive of 1-year mortality in both univariate (odds ratio, 1.84; 95% confidence interval, 1.03-3.3; P = .038) and multivariate (odds ratio, 2.1; 95% confidence interval, 1.01-4.3; P = .047) analyses. Conclusions In our experience, CS as a bridge to HT results in a higher incidence of primary graft failure, frequent infection, and mortality at 1-year follow-up. Mechanical ventilation added to CS has a clear unfavorable prognostic impact. CS as a bridge to HT was shown to be predictive of 1-year mortality in both univariate and multivariate analyses.
