RESUMO
BACKGROUND: The selective cardiac myosin activator omecamtiv mecarbil has been shown to improve cardiac function in patients with heart failure with a reduced ejection fraction. Its effect on cardiovascular outcomes is unknown. METHODS: We randomly assigned 8256 patients (inpatients and outpatients) with symptomatic chronic heart failure and an ejection fraction of 35% or less to receive omecamtiv mecarbil (using pharmacokinetic-guided doses of 25 mg, 37.5 mg, or 50 mg twice daily) or placebo, in addition to standard heart-failure therapy. The primary outcome was a composite of a first heart-failure event (hospitalization or urgent visit for heart failure) or death from cardiovascular causes. RESULTS: During a median of 21.8 months, a primary-outcome event occurred in 1523 of 4120 patients (37.0%) in the omecamtiv mecarbil group and in 1607 of 4112 patients (39.1%) in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.86 to 0.99; P = 0.03). A total of 808 patients (19.6%) and 798 patients (19.4%), respectively, died from cardiovascular causes (hazard ratio, 1.01; 95% CI, 0.92 to 1.11). There was no significant difference between groups in the change from baseline on the Kansas City Cardiomyopathy Questionnaire total symptom score. At week 24, the change from baseline for the median N-terminal pro-B-type natriuretic peptide level was 10% lower in the omecamtiv mecarbil group than in the placebo group; the median cardiac troponin I level was 4 ng per liter higher. The frequency of cardiac ischemic and ventricular arrhythmia events was similar in the two groups. CONCLUSIONS: Among patients with heart failure and a reduced ejection, those who received omecamtiv mecarbil had a lower incidence of a composite of a heart-failure event or death from cardiovascular causes than those who received placebo.

AIMS: Aims were to evaluate (1) reclassification of patients from heart failure with mildly reduced (HFmrEF) to reduced (HFrEF) ejection fraction when an EF = 40% was considered as HFrEF, (2) role of EF digit bias, ie, EF reporting favouring 5% increments; (3) outcomes in relation to missing and biased EF reports, in a large multinational HF registry. METHODS AND RESULTS: Of 25,154 patients in the European Society of Cardiology (ESC) HF Long-Term registry, 17% had missing EF and of those with available EF, 24% had HFpEF (EF≥50%), 21% HFmrEF (40%-49%) and 55% HFrEF (<40%) according to the 2016 ESC guidelines´ classification. EF was "exactly" 40% in 7%, leading to reclassifying 34% of the HFmrEF population defined as EF = 40% to 49% to HFrEF when applying the 2021 ESC Guidelines classification (14% had HFmrEF as EF = 41% to 49% and 62% had HFrEF as EF≤40%). EF was reported as a value ending with 0 or 5 in â¼37% of the population. Such potential digit bias was associated with more missing values for other characteristics and higher risk of all-cause death and HF hospitalization. Patients with missing EF had higher risk of all-cause and CV mortality, and HF hospitalization compared to those with recorded EF. CONCLUSIONS: Many patients had reported EF = 40%. This led to substantial reclassification of EF from old HFmrEF (40%-49%) to new HFrEF (≤40%). There was considerable digit bias in EF reporting and missing EF reporting, which appeared to occur not at random and may reflect less rigorous overall care and worse outcomes.

In this observational and multicenter study, that included all patients who underwent a heart transplantation (HT) in Spain from 1984 to 2018, we analyzed the incidence, management, and prognosis of colorectal cancer (CRC) after HT. Of 6,244 patients with a HT and a median follow-up of 8.8 years since the procedure, 116 CRC cases (11.5% of noncutaneous solid cancers other than lymphoma registered) were diagnosed, mainly adenocarcinomas, after a mean of 9.3 years post-HT. The incidence of CRC increased with age at HT from 56.6 per 100,000 person-years among under 45 year olds to 436.4 per 100,000 person-years among over 64 year olds. The incidence rates for age-at-diagnosis groups were significantly greater than those estimated for the general Spanish population. Curative surgery, performed for 62 of 74 operable tumors, increased the probability of patient survival since a diagnosis of CRC, from 31.6% to 75.7% at 2 years, and from 15.8% to 48.6% at 5 years, compared to patients with inoperable tumors. Our results suggest that the incidence of CRC among HT patients is greater than in the general population, increasing with age at HT.

Heart transplantation is advocated in selected patients with advanced heart failure in the absence of contraindications. Principal challenges in heart transplantation centre around an insufficient and underutilized donor organ pool, the need to individualize titration of immunosuppressive therapy, and to minimize late complications such as cardiac allograft vasculopathy, malignancy, and renal dysfunction. Advances have served to increase the organ donor pool by advocating the use of donors with underlying hepatitis C virus infection and by expanding the donor source to use hearts donated after circulatory death. New techniques to preserve the donor heart over prolonged ischaemic times, and enabling longer transport times in a safe manner, have been introduced. Mechanical circulatory support as a bridge to transplantation has allowed patients with advanced heart failure to avoid progressive deterioration in hepato-renal function while awaiting an optimal donor organ match. The management of the heart transplantation recipient remains a challenge despite advances in immunosuppression, which provide early gains in rejection avoidance but are associated with infections and late-outcome challenges. In this article, we review contemporary advances and challenges in this field to focus on donor recovery strategies, left ventricular assist devices, and immunosuppressive monitoring therapies with the potential to enhance outcomes. We also describe opportunities for future discovery to include a renewed focus on long-term survival, which continues to be an area that is under-studied and poorly characterized, non-human sources of organs for transplantation including xenotransplantation as well as chimeric transplantation, and technology competitive to human heart transplantation, such as tissue engineering.

BACKGROUND: Remodeling of the extracellular matrix (ECM) is a hallmark of heart failure (HF). Our previous analysis of the secretome of murine cardiac fibroblasts returned ADAMTS5 (a disintegrin and metalloproteinase with thrombospondin motifs 5) as one of the most abundant proteases. ADAMTS5 cleaves chondroitin sulfate proteoglycans such as versican. The contribution of ADAMTS5 and its substrate versican to HF is unknown. METHODS: Versican remodeling was assessed in mice lacking the catalytic domain of ADAMTS5 (Adamts5ΔCat). Proteomics was applied to study ECM remodeling in left ventricular samples from patients with HF, with a particular focus on the effects of common medications used for the treatment of HF. RESULTS: Versican and versikine, an ADAMTS-specific versican cleavage product, accumulated in patients with ischemic HF. Versikine was also elevated in a porcine model of cardiac ischemia/reperfusion injury and in murine hearts after angiotensin II infusion. In Adamts5ΔCat mice, angiotensin II infusion resulted in an aggravated versican build-up and hyaluronic acid disarrangement, accompanied by reduced levels of integrin ß1, filamin A, and connexin 43. Echocardiographic assessment of Adamts5ΔCat mice revealed a reduced ejection fraction and an impaired global longitudinal strain on angiotensin II infusion. Cardiac hypertrophy and collagen deposition were similar to littermate controls. In a proteomics analysis of a larger cohort of cardiac explants from patients with ischemic HF (n=65), the use of ß-blockers was associated with a reduction in ECM deposition, with versican being among the most pronounced changes. Subsequent experiments in cardiac fibroblasts confirmed that ß1-adrenergic receptor stimulation increased versican expression. Despite similar clinical characteristics, patients with HF treated with ß-blockers had a distinct cardiac ECM profile. CONCLUSIONS: Our results in animal models and patients suggest that ADAMTS proteases are critical for versican degradation in the heart and that versican accumulation is associated with impaired cardiac function. A comprehensive characterization of the cardiac ECM in patients with ischemic HF revealed that ß-blockers may have a previously unrecognized beneficial effect on cardiac chondroitin sulfate proteoglycan content.

BACKGROUND: Serelaxin is a recombinant form of human relaxin-2, a vasodilator hormone that contributes to cardiovascular and renal adaptations during pregnancy. Previous studies have suggested that treatment with serelaxin may result in relief of symptoms and in better outcomes in patients with acute heart failure. METHODS: In this multicenter, double-blind, placebo-controlled, event-driven trial, we enrolled patients who were hospitalized for acute heart failure and had dyspnea, vascular congestion on chest radiography, increased plasma concentrations of natriuretic peptides, mild-to-moderate renal insufficiency, and a systolic blood pressure of at least 125 mm Hg, and we randomly assigned them within 16 hours after presentation to receive either a 48-hour intravenous infusion of serelaxin (30 µg per kilogram of body weight per day) or placebo, in addition to standard care. The two primary end points were death from cardiovascular causes at 180 days and worsening heart failure at 5 days. RESULTS: A total of 6545 patients were included in the intention-to-treat analysis. At day 180, death from cardiovascular causes had occurred in 285 of the 3274 patients (8.7%) in the serelaxin group and in 290 of the 3271 patients (8.9%) in the placebo group (hazard ratio, 0.98; 95% confidence interval [CI], 0.83 to 1.15; P = 0.77). At day 5, worsening heart failure had occurred in 227 patients (6.9%) in the serelaxin group and in 252 (7.7%) in the placebo group (hazard ratio, 0.89; 95% CI, 0.75 to 1.07; P = 0.19). There were no significant differences between the groups in the incidence of death from any cause at 180 days, the incidence of death from cardiovascular causes or rehospitalization for heart failure or renal failure at 180 days, or the length of the index hospital stay. The incidence of adverse events was similar in the two groups. CONCLUSIONS: In this trial involving patients who were hospitalized for acute heart failure, an infusion of serelaxin did not result in a lower incidence of death from cardiovascular causes at 180 days or worsening heart failure at 5 days than placebo.

INTRODUCTION AND OBJECTIVES: The Index for Mortality Prediction After Cardiac Transplantation (IMPACT) score was derived and validated as a predictor of mortality after heart transplantation (HT). The primary objective of this work is to externally validate the IMPACT score in a contemporary Spanish cohort. METHODS: Spanish Heart Transplant Registry data were used to identify adult (>16 years) HT patients between January 2000 and December 2015. Retransplantation, multiorgan transplantation and patients in whom at least one of the variables required to calculate the IMPACT score was missing were excluded from the analysis (N = 2810). RESULTS: Median value of the IMPACT score was five points (IQR: 3, 8). Overall, 1-year survival rate was 79.1%. Kaplan-Meier 1-year survival rates by IMPACT score categories (0-2, 3-5, 6-9, 10-14, ≥15) were 84.4%, 81.5%, 79.3%, 77.3%, and 58.5%, respectively (Log-Rank test: p < .001). Performance analysis showed a good calibration (Hosmer-Lemeshow chi-square for 1 year was 7.56; p = .47) and poor discrimination ability (AUC-ROC .59) of the IMPACT score as a predictive model. CONCLUSIONS: In a contemporary Spanish cohort, the IMPACT score failed to accurately predict the risk of death after HT.

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.

Male patients are at increased risk for developing malignancy postheart transplantation (HT); however, real incidence and prognosis in both genders remain unknown. The aim of this study was to assess differences in incidence and mortality related to malignancy between genders in a large cohort of HT patients. Incidence and mortality rates were calculated for all tumors, skin cancers (SCs), lymphoma, and nonskin solid cancers (NSSCs) as well as survival since first diagnosis of neoplasia. 5865 patients (81.6% male) were included. Total incidence rates for all tumors, SCs, and NSSCs were lower in females [all tumors: 25.7 vs. 44.8 per 1000 person-years; rate ratio (RR) 0.68, (0.60-0.78), P < 0.001]. Mortality rates were also lower in females for all tumors [94.0 (77.3-114.3) vs. 129.6 (120.9-138.9) per 1000 person-years; RR 0.76, (0.62-0.94), P = 0.01] and for NSSCs [125.0 (95.2-164.0) vs 234.7 (214.0-257.5) per 1000 person-years; RR 0.60 (0.44-0.80), P = 0.001], albeit not for SCs or lymphoma. Female sex was associated with a better survival after diagnosis of malignancy [log-rank p test = 0.0037; HR 0.74 (0.60-0.91), P = 0.004]. In conclusion, incidence of malignancies post-HT is higher in males than in females, especially for SCs and NSSCs. Prognosis after cancer diagnosis is also worse in males.

Advanced heart failure (HF) is characterized by a progressive worsening of symptoms disabling for daily life, refractory to all therapies, and with high mortality. These patients may be candidates for life-prolonging therapies, such as heart transplantation (HT) or long-term (LT) mechanical circulatory support (MCS) or must just require palliative therapies. The 1-year survival after HT and/or LT-MCS is approaching 80% to 90%, being patient selection and timely referral to advanced HF centers critical for optimal outcomes. There is no single symptom, sign, or test that can identify these patients and different classifications are complementary and helpful for clinical decision-making.

BACKGROUND: Anticoagulation in heart transplant (HT) recipients increases the risk of hemorrhagic complications, so correct reversal of anticoagulation is needed. Dabigatran, a direct thrombin inhibitor, is increasingly used for anticoagulation in patients with non-valvular atrial fibrillation (NVAF) whose effect can be reversed by idarucizumab. AIM: To present a nationwide experience using idarucizumab for the urgent reversal of dabigatran before HT. METHODS: Multicenter observational study in 12 Spanish centers to analyze the clinical outcomes after using idarucizumab before HT surgery. RESULTS: Fifty-three patients were included (81.1% male). 7.5% required re-operation in the immediate postoperative period to control bleeding and 66% transfusion of blood products. Median length of stay in the intensive care unit was 6 days and total hospital stay 24 days. 30-day survival was 92.4%. There were four deaths in the first month, all in the first 5 days post-HT. Only in one patient (transplanted due to a congenital heart disease, after sternotomy) who had surgical problems and right ventricular failure post-HT death was associated with bleeding. CONCLUSIONS: These results may support the use of dabigatran as an alternative to vitamin K antagonists in patients listed for HT requiring anticoagulation due to NVAF. More studies are needed to reaffirm these observations.

INTRODUCTION: Infection is one of the most significant complications following heart transplantation (HT). The aim of this study was to identify specific risk factors for early postoperative infections in HT recipients, and to develop a multivariable predictive model to identify HT recipients at high risk. METHODS: A single-center, observational, and retrospective study was conducted. The dependent variable was in-hospital postoperative infection. We examined demographic and epidemiological data from donors and recipients, surgical features, and adverse postoperative events as independent variables. Backwards, stepwise multivariable logistic regression with a P-value < 0.05 was used to identify clinical factors independently associated with the risk of in-hospital postoperative infections following HT. RESULTS: Six hundred seventy-seven patients were included in this study. During the in-hospital postoperative period, 348 episodes of infection were diagnosed in 239 (35.9%) patients. Seven variables were identified as independent clinical predictors of early postoperative infection after HT: history of diabetes mellitus, previous sternotomy, preoperative mechanical ventilation, primary graft failure, major surgical bleeding, use of mycophenolate mofetil, and use of itraconazole. Based on the results of multivariable models, we constructed a 7-variable (8-point) score to predict the risk of in-hospital postoperative infection in HT recipients, which showed a reasonable ability to predict the risk of in-hospital postoperative infection in this population. Prospective external validation of this new score is warranted to confirm its clinical applicability. CONCLUSIONS: In-hospital postoperative infection is a common complication after HT, affecting 35% of patients who underwent this procedure at our institution. Diabetes mellitus, previous sternotomy, preoperative mechanical ventilation, primary graft failure, major surgical bleeding, use of mycophenolate mofetil, and itraconazole were all independent clinical predictors of early postoperative infection after HT.

PURPOSE: Current clinical recommendations do not emphasise superiority of any of diuretics, but available reports are very encouraging and suggest beneficial effects of torasemide. This study aimed to compare the effect of torasemide and furosemide on long-term outcomes and New York Heart Association (NYHA) class change in patients with chronic heart failure (HF). METHODS: Of 2019 patients enrolled in Polish parts of the heart failure registries of the European Society of Cardiology (Pilot and Long-Term), 1440 patients treated with a loop diuretic were included in the analysis. The main analysis was performed on matched cohorts of HF patients treated with furosemide and torasemide using propensity score matching. RESULTS: Torasemide was associated with a similar primary endpoint (all-cause death; 9.8% vs. 14.1%; p = 0.13) occurrence and 23.8% risk reduction of the secondary endpoint (a composite of all-cause death or hospitalisation for worsening HF; 26.4% vs. 34.7%; p = 0.04). Treatment with both torasemide and furosemide was associated with the significantly most frequent occurrence of the primary (23.8%) and secondary (59.2%) endpoints. In the matched cohort after 12 months, NYHA class was higher in the furosemide group (p = 0.04), while furosemide use was associated with a higher risk (20.0% vs. 12.9%; p = 0.03) of worsening ≥ 1 NYHA class. Torasemide use impacted positively upon the primary endpoint occurrence, especially in younger patients (aged < 65 years) and with dilated cardiomyopathy. CONCLUSIONS: Our findings contribute to the body of research on the optimal diuretic choice. Torasemide may have advantageous influence on NYHA class and long-term outcomes of HF patients, especially younger patients or those with dilated cardiomyopathy, but it needs further investigations in prospective randomised trials.

OBJECTIVES: To evaluate whether carotid disease is associated with coronary artery disease (CAD) extension in patients undergoing treadmill exercise stress echocardiography (EE). METHODS: We retrospectively studied 156 patients without previous vascular disease who underwent EE, carotid ultrasonography, and coronary angiography between 2002 and 2013. Low-, intermediate-, and high-risk EE were defined as negative, localized ischemia, and multivessel/extensive ischemia EE respectively; carotid disease according to Mannheim and American Society of Echocardiography Consensus and CAD extension from zero to three vessel disease as stenosis ≥50% by visual assessment. RESULTS: Of the 156 patients, 67 (42.9%), 43 (27.6%), 22 (14.1%), and 24 (15.4%) had zero, one, two, and three vessel disease respectively. Age (P = 0.047), male sex (P = 0.010), diabetes mellitus (P = 0.039), smoking habit (P = 0.015), fasting plasma glucose (P = 0.021), European Systematic COronary Risk Evaluation (P = 0.003), pretest CAD probability (P = 0.003), high-risk EE (P < 0.001), and carotid plaque presence (CP) (P < 0.001) were associated in univariate analysis with more extensive CAD. Predictors of CAD extension in multivariate analysis were high-risk EE (odds ratio [OR] 2.42, P < 0.001), CP presence (OR 1.75, P = 0.004), and pretest CAD probability >65% (OR 1.49, P = 0.023). CP was also associated with multivessel CAD in the 53 patients with low- or intermediate-risk EE (P = 0.001). CONCLUSIONS: CP is associated with CAD extension in patients with ischemic heart disease suspicion undergoing EE. Patients with CP could benefit from a more aggressive therapeutic strategy regarding patients without carotid disease and similar risk EE, especially in intermediate- and/or low-risk test where guidelines recommend initially optimal medical treatment.

BACKGROUND: Identifying readmission predictors in heart failure (HF) patients may help guide preventative efforts and save costs. We aimed to identify 15- and 30-day readmission predictors due to cardiovascular reasons. METHODS AND RESULTS: A total of 1831 patients with acute HF admission were prospectively followed during a year. Patient-associated variables were gathered at admission/discharge and events during follow-up. A multivariate Fine and Gray competing risk regression model and a cumulative incidence function were used to identify predictors and build a risk score model for 15- and 30-day readmission. The 15- and 30-day readmission rates due to cardiovascular reasons were 7.1% and 13.9%. Previous acute myocardial infarction, congestive signs at discharge, and length of stay > 9 days were predictors of 15- and 30-day readmission, while much weight loss and large NT-ProBNP reduction were protective factors. The NT-ProBNP reduction was larger at 30 days (> 55%) vs 15 days (> 40%) to protect from readmission. Glomerular filtration rate at discharge < 60 mL/min/1.73m2 and > 1 previous admissions due to HF were predictors of 30-day readmission, while first post-discharge control at an HF unit was a protective factor. CONCLUSIONS: Previous identified factors for early readmission were confirmed. The NT-ProBNP reduction should be increased (> 55%) to protect from 30-day readmission.

Aim: To investigate the characteristics long-term prognostic implications (up to â¼2.2 years) of atrial fibrillation (AF) compared to sinus rhythm (SR), between acute and chronic heart failure (HF) with reduced (HFrEF < 40%), mid-range (HFmrEF 40-49%), and preserved (HFpEF ≥ 50%) ejection fraction (EF). Methods and results: Data from the observational, prospective, HF long-term registry of the European Society of Cardiology were analysed. A total of 14 964 HF patients (age 66 ± 13 years, 67% male; 53% HFrEF, 21% HFmrEF, 26% HFpEF) were enrolled. The prevalence of AF was 27% in HFrEF, 29% in HFmrEF, and 39% in HFpEF. Atrial fibrillation was associated with older age, lower functional capacity, and heightened physical signs of HF. Crude rates of mortality and HF hospitalization were higher in patients with AF compared to SR, in each EF subtype. After multivariable adjustment, the hazard ratio of AF for HF hospitalizations was: 1.036 (95% CI 0.888-1.208, P = 0.652) in HFrEF, 1.430 (95% CI 1.087-1.882, P = 0.011) in HFmrEF, and 1.487 (95% CI 1.195-1.851, P < 0.001) in HFpEF; and for combined all-cause death or HF hospitalizations: 0.957 (95% CI 0.843-1.087, P = 0.502), 1.302 (95% CI 1.055-1.608, P = 0.014), and 1.365 (95% CI 1.152-1.619, P < 0.001), respectively. In patients with HFrEF, AF was not associated with worse outcomes in those presenting with either an acute or a chronic presentation of HF. Conclusions: The prevalence of AF increases with increasing EF but its association with worse cardiovascular outcomes, remained significant in patients with HFpEF and HFmrEF, but not in those with HFrEF.

Aims: We aimed to determine whether treatment with sildenafil improves outcomes of patients with persistent pulmonary hypertension (PH) after correction of valvular heart disease (VHD). Methods and results: The sildenafil for improving outcomes after valvular correction (SIOVAC) study was a multricentric, randomized, parallel, and placebo-controlled trial that enrolled stable adults with mean pulmonary artery pressure ≥ 30 mmHg who had undergone a successful valve replacement or repair procedure at least 1 year before inclusion. We assigned 200 patients to receive sildenafil (40 mg three times daily, n = 104) or placebo (n = 96) for 6 months. The primary endpoint was the composite clinical score combining death, hospital admission for heart failure (HF), change in functional class, and patient global self-assessment. Only 27 patients receiving sildenafil improved their composite clinical score, as compared with 44 patients receiving placebo; in contrast 33 patients in the sildenafil group worsened their composite score, as compared with 14 in the placebo group [odds ratio 0.39; 95% confidence interval (CI) 0.22-0.67; P < 0.001]. The Kaplan-Meier estimates for survival without admission due to HF were 0.76 and 0.86 in the sildenafil and placebo groups, respectively (hazard ratio 2.0, 95% CI = 1.0-4.0; log-rank P = 0.044). Changes in 6-min walk test distance, natriuretic peptides, and Doppler-derived systolic pulmonary pressure were similar in both groups. Conclusion: Treatment with sildenafil in patients with persistent PH after successfully corrected VHD is associated to worse clinical outcomes than placebo. Off-label usage of sildenafil for treating this source of left heart disease PH should be avoided. The trial is registered with ClinicalTrials.gov, number NCT00862043.
