AIMS: Information on the prevalence, outcome and factors associated with heart failure in patients with adult congenital heart disease (CHD) (ACHD-HF) is lacking. We aimed at assessing the prevalence and outcome of ACHD-HF, the variables associated with ACHD-HF, and the differences between major anatomical/pathophysiological ACHD subgroups. METHODS AND RESULTS: We included 3905 patients (age 35.4 ± 13.2 years) under active follow-up in our institution (last visit >2010). Outcome of ACHD-HF cases was compared with sex- and age-matched cases. Univariable and multivariable binary logistic regression with ACHD-HF diagnosis as a dependent variable was performed. Overall prevalence of ACHD-HF was 6.4% (mean age 49.5 ± 16.7 years), but was higher in patients with cyanotic CHD (41%), Fontan circulation (30%), and a systemic right ventricle (25%). All-cause mortality was higher in ACHD-HF cases when compared with controls (mortality rate ratio 4.67 (2.36-9.27); P = 0.0001). In multivariable logistic regression analysis, age at latest follow-up [per 10 years; odds ratio (OR) 1.52; 95% confidence interval (CI) 1.31-1.77], infective endocarditis (OR 4.11; 95%CI 1.80-9.38), history of atrial arrhythmia (OR 3.52; 95%CI 2.17-5.74), pacemaker implantation (OR 2.66; 95% CI 1.50-4.72), end-organ dysfunction (OR 2.41; 95% CI 1.03-5.63), New York Heart Association class (OR 9.28; 95% CI 6.04-14.25), heart rate (per 10 bpm; OR 1.27; 95% CI 1.08-1.50), ventricular dysfunction (OR 3.62; 95% CI 2.54-5.17), and pulmonary hypertension severity (OR 1.66; 95% CI 1.21-2.30) were independently related to the presence of ACHD-HF. Some variables (age, atrial arrhythmia, pacemaker, New York Heart Association, and ventricular dysfunction) were related to ACHD-HF in all anatomical/physiological subgroups, whereas others were not. CONCLUSIONS: ACHD-HF is prevalent especially in complex CHD and is associated with poor prognosis. Our data provide insight in the factors related to ACHD-HF including differences between specific anatomical and physiological subgroups. ispartof: ESC HEART FAILURE vol:8 issue:4 pages:2940-2950 ispartof: location:England status: published

Methods and results: From the metabolic road to diastolic heart failure: diastolic heart failure (MEDIA‐DHF) study, 111 patients were included in this substudy: 77 AHF (43 HFPEF and 34 HFREF) and 34 non‐cardiac dyspnea patients. Echocardiographic measurements and blood samples were obtained within 4 h of presentation at the emergency department and before hospital discharge. In AHF patients, echocardiographic indices of cardiac and venous pressures, including inferior vena cava diameter [from 22 (16–24) mm to 13 (11–18) mm, P = 0.009], its respiratory variability [from 32 (8–44) % to 43 (29–70) %, P = 0.04], medial E/e' [from 21.1 (15.8–29.6) to 16.6 (11.7–24.3), P = 0.004], and E wave deceleration time [from 129 (105–156) ms to 166 (128–203) ms, P = 0.003], improved during hospitalization, similarly in HFPEF and HFREF patients. By contrast, no changes were seen in non‐cardiac dyspnea patients. In AHF patients, all plasma biomarkers of cardiac and venous pressures, namely B‐type natriuretic peptide [from 935 (514–2037) pg/mL to 308 (183–609) pg/mL, P < 0.001], mid‐regional pro‐atrial natriuretic peptide [from 449 (274–653) pmol/L to 366 (242–549) pmol/L, P < 0.001], and soluble CD‐146 levels [from 528 (406–654) ng/mL to 450 (374–529) ng/mL, P = 0.003], significantly decreased during hospitalization, similarly in HFPEF and HFREF patients. Echocardiographic parameters of cardiac chamber dimensions [left ventricular end‐diastolic volume: from 120 (76–140) mL to 118 (95–176) mL, P = 0.23] and cardiac index [from 2.1 (1.6–2.6) mL/min/m2 to 1.9 (1.4–2.4) mL/min/m2, P = 0.55] were unchanged in AHF patients, except tricuspid annular plane systolic excursion (TAPSE) that improved during hospitalization [from 16 (15–19) mm to 19 (17–21) mm, P = 0.04]. Estimated plasma volume increased in both AHF [from 4.8 (4.2–5.6) to 5.1 (4.4–5.8), P = 0.03] and non‐cardiac dyspnea patients (P = 0.01). Serum creatinine [from 1.18 (0.90–1.53) to 1.19 (0.86–1.70) mg/dL, P = 0.89] and creatinine‐based estimated glomerular filtration rate [from 59 (40–75) mL/min/1.73m2 to 56 (38–73) mL/min/1.73m2, P = 0.09] were similar, while plasma cystatin C [from 1.50 (1.20–2.27) mg/L to 1.78 (1.33–2.59) mg/L, P < 0.001] and neutrophil gelatinase associated lipocalin (NGAL) [from 127 (95–260) ng/mL to 167 (104–263) ng/mL, P = 0.004] increased during hospitalization in AHF. Conclusions: Echocardiographic parameters and plasma biomarkers of cardiac and venous pressures improved during AHF hospitalization in both acute HFPEF and HFREF patients, while cardiac chamber dimensions, cardiac output, and estimated plasma volume showed minimal changes., This study was supported by a grant from the European Union funded by the Seventh Framework Programme for Health in 2010 (FP7-HEALTH-2010-MEDIA; Luxembourg) (F.Z., P.R., A.

Knowledge on the influence of specific genotypes on the phenotypic expression of hypertrophic cardiomyopathy (HCM) is emerging. The objective of this study was to evaluate the genotype-phenotype relation in HCM patients and to construct a score to predict the genetic yield based to improve counseling. Unrelated HCM patients who underwent genetic testing were included in the analysis. Multivariate logistic regression was performed to identify variables that predict a positive genetic test. A weighted score was constructed based on the odds ratios. In total, 378 HCM patients were included of whom 141 carried a mutation (global yield 37%), 181 were mutation negative and 56 only carried a variant of unknown significance. We identified age at diagnosis

Aims Congestion is a central feature of acute heart failure (HF) and its assessment is important for clinical decisions (e.g. tailoring decongestive treatments). It remains uncertain whether patients with acute HF with preserved ejection fraction (HFpEF) are comparably congested as in acute HF with reduced EF (HFrEF). This study assessed congestion, right ventricular (RV) and renal dysfunction in acute HFpEF, HFrEF and non-cardiac dyspnoea. Methods and results We compared echocardiographic and circulating biomarkers of congestion in 146 patients from the MEDIA-DHF study: 101 with acute HF (38 HFpEF, 41 HFrEF, 22 HF with mid-range ejection fraction) and 45 with non-cardiac dyspnoea. Compared with non-cardiac dyspnoea, patients with acute HF had larger left and right atria, higher E/e', pulmonary artery systolic pressure and inferior vena cava (IVC) diameter at rest, and lower IVC variability (all P 0.05) compared with HFrEF. Conclusion In acute conditions, HFpEF and HFrEF presented in a comparable state of venous congestion, with similarly altered RV and kidney function, despite higher BNP in HFrEF.

Aims Structural and functional left ventricular alterations can occur in heart failure (HF), referred to as left ventricular reverse remodelling (LVRR). This study aimed to define novel predictors of LVRR besides well-known effects of medical and device therapy. Methods and results From echographic database, we included 295 patients with both left ventricular ejection fraction (LVEF) ≤45% and indexed left ventricular end-diastolic diameter ≥33 mm/m2 and who had at least two echocardiographic exams with a delay between 3 and 12 months. LVRR was defined as the combination of (i) normalization of LVEF (LVEF ≥50%) or increase in LVEF ≥10% and (ii) a decrease in indexed left ventricular end-diastolic diameter ≥10%. Clinical follow-up was also obtained. LVRR occurred in 53 (18%) patients. Patients in the LVRR group were more likely to present with de novo HF (75% vs. 42%), had lower LVEF and left ventricular end-diastolic volumes at index examination, yet a higher body mass index (BMI) than non-LVRR patients. Obesity was observed in 25% of LVRR patients vs. 14% in others. In multivariate analyses, BMI (per each 1 kg/m2 increase) emerged as a predictor of LVRR: odds ratio 1.10 (95% confidence interval 1.02–1.19) after adjustment to other predictors of LVRR. During a mean follow-up of 37 months, 32% of patients had a major adverse cardiac event; de novo HF, age, and LVEF were associated with major adverse cardiac event. Conclusions We identified significant relationship between high BMI and LVRR. This intriguing novel finding deserves further study.

Heart failure (HF) is a common, costly, disabling, and deadly clinical syndrome and often associated with one or several co-morbidities complicating its treatment or worsening its symptoms. During the last decade, iron deficiency (ID) got recognized as a frequent, debilitating yet easily treatable co-morbidity in HF. In this review, we focus on new evidence that emerged during the last 5 years and discuss the epidemiology, the causes, and the clinical consequences of ID in HF. Apart from replenishing iron stores, intravenous iron improves patients’ symptoms, perceived quality of life (QoL), exercise capacity, and hospitalization rates. These beneficial effects cannot be attributed to oral iron, as increased hepcidin levels, typical in inflammatory states such as HF, preclude resorption of iron from the gut. Intravenous iron is the only valid treatment option for ID in HF. However, there are several burning research questions and gaps in evidence remaining in this research field.

BackgroundChronic kidney disease (CKD) is common in patients after heart transplantation (HTx). We assessed whether in HTx recipients the proteomic urinary classifier CKD273 or sequenced urinary peptides revealing the parental proteins correlated with the estimated glomerular filtration rate (eGFR).MethodsIn 368 HTx patients, we measured the urinary peptidome and analysed CKD273 and 48 urinary peptides with a detectable signal in >95% of participants. After 9.1 months (median), eGFR and the urinary biomarkers were reassessed.ResultsIn multivariable Bonferroni-corrected analyses of the baseline data, a 1-SD increase in CKD273 was associated with a 11.4 [95% confidence interval (CI) 7.25–15.5] mL/min/1.73 m2 lower eGFR and an odds ratio of 2.63 (1.56–4.46) for having eGFR ConclusionsWith the exception of baseline eGFR, CKD273 was more closer associated with imminent renal dysfunction than 24-h proteinuria. Fragments of collagen I and mucin-1—respectively, positively and inversely associated with eGFR and change in eGFR—are single-peptide markers associated with renal dysfunction.

BACKGROUND: Cardiac allograft vasculopathy (CAV) is a major complication limiting long-term survival after heart transplantation (HTx). However, long-term outcome data of HTx recipients with detailed information on angiographic severity are scarce. METHODS: The study included 501 HTx recipients with angiographic follow-up up to 20 years post-transplant. All coronary angiograms were classified according to the International Society for Heart and Lung Transplantation (ISHLT) grading scale. RESULTS: CAV prevalence increased over time after transplantation, reaching 10% at 1 year, 44% at 10 years, and 59% at 20 years. Older donor age (hazard ratio [HR] 1.38 per 10 years, 1.20-1.59, p < 0.001), male donor sex (HR 1.86, 1.31-2.64, p < 0.001), stroke as donor cause of death (HR 1.47, 1.04-2.09, p = 0.03), recipient pre-transplant hemodynamic instability (HR 1.79, 1.15-2.77, p = 0.01), post-transplant smoking (HR 1.59, 1.06-2.39, p = 0.03), and first-year treated rejection episodes (HR 1.49, 1.01-2.20, p = 0.046) were independent risk factors for CAV. Baseline anti-metabolite drug use (HR 0.57, 0.34-0.95, p = 0.03) and more recent transplant date (HR 0.78 per 10 years, 0.62-0.99, p = 0.04) were protective factors. Compared with patients without CAV, the HR for death or retransplantation was 1.22 (0.85-1.76, p = 0.28) for CAV 1, 1.86 (1.08-3.22, p = 0.03) for CAV 2, and 5.71 (3.64-8.94, p < 0.001) for CAV 3. CONCLUSIONS: CAV is highly prevalent in HTx recipients and is explained by immunologic and non-immunologic factors. Higher ISHLT CAV grades are independently associated with worse graft survival. ispartof: JOURNAL OF HEART AND LUNG TRANSPLANTATION vol:38 issue:11 pages:1189-1196 ispartof: location:United States status: published

Aims Cardiac transplantation is the only curative therapy for end-stage heart failure. Fibrosis is one of the major causes for impaired function of cardiac allografts. MicroRNAs, a class of small non-coding RNAs, play a critical role in the development of cardiovascular disease, but the role of microRNAs in cardiac allograft failure is not well understood. Methods and results To uncover a role of microRNAs during cardiac graft fibrosis, we generated global microRNA profiles in allogeneic (BALB/c in C57BL/6N) and isogeneic (C57BL/6N in C57BL/6N) murine hearts after transplantation. miR-21 together with cardiac fibrosis was increased in cardiac allografts compared with isografts. Likewise, patients with cardiac rejection after heart transplantation showed increased cardiac miR-21 levels. miR-21 was induced upon treatment with IL-6 in a monocyte cell line. Overexpression of miR-21 in this monocyte cell line activated a fibrotic gene programme and promoted monocyte-to-fibrocyte transition together with activation of chemokine (C-C) motif ligand 2 (monocyte chemoattractant protein 1) via the phosphatase and tensin homologue/activator protein 1 regulatory axis. In vivo , both genetic and pharmacological inhibition of miR-21 successfully reduced fibrosis and fibrocyte accumulation in cardiac allografts. Conclusion Thus, inhibition of miR-21 is a novel strategy to target fibrosis development in cardiac allografts.

OBJECTIVES: Heart transplant (HTx) recipients have a high heart rate (HR), because of graft denervation and are frequently started on β-blockade (BB). We assessed whether BB and HR post HTx are associated with a specific urinary proteomic signature. METHODS: In 336 HTx patients (mean age, 56.8 years; 22.3% women), we analyzed cross-sectional data obtained 7.3 years (median) after HTx. We recorded medication use, measured HR during right heart catheterization, and applied capillary electrophoresis coupled with mass spectrometry to determine the multidimensional urinary classifiers HF1 and HF2 (known to be associated with left ventricular dysfunction), ACSP75 (acute coronary syndrome) and CKD273 (renal dysfunction) and 48 sequenced urinary peptides revealing the parental proteins. RESULTS: In adjusted analyses, HF1, HF2 and CKD273 (p ≤ 0.024) were higher in BB users than non-users with a similar trend for ACSP75 (p = 0.06). Patients started on BB within 1 year after HTx and non-users had similar HF1 and HF2 levels (p ≥ 0.098), whereas starting BB later was associated with higher HF1 and HF2 compared with non-users (p ≤ 0.014). There were no differences in the urinary biomarkers (p ≥ 0.27) according to HR. BB use was associated with higher urinary levels of collagen II and III fragments and non-use with higher levels of collagen I fragments. CONCLUSIONS: BB use, but not HR, is associated with a urinary proteomic signature that is usually associated with worse outcome, because unhealthier conditions probably lead to initiation of BB. Starting BB early after HTx surgery might be beneficial. ispartof: PLOS ONE vol:13 issue:9 ispartof: location:United States status: published

Acute heart failure (AHF) is a major health problem worldwide and trials to assess novel therapies are increasingly global, as a means to reduce costs, expedite timelines, provide broad applicability, and satisfy regulatory authorities.The significant geographic differences in patient characteristics, outcomes, and treatment effect may affect trial results and raise important questions about generalizability of the results to a broader population.

We compared survival in our heart recipients with survival rates reported by the International Society of Heart and Lung Transplantation (ISHLT) Registry. As recipient and donor characteristics are changing over time, we studied four different eras. In order to differentiate between short- and long-term survival, we analyzed both overall survival and survival at one year. Obviously, this exercise is only relevant when baseline donor and recipient characteristics are comparable, as these differences may affect the outcome in opposite directions. To overcome this potential bias as much as possible, we calculated the Index for Mortality Prediction After Cardiac Transplantation (IMPACT)-scores and the Donor Risk Index (DRI). Looking to our results, we found that our DRIs in the different eras are almost equal to those obtained from the United Network for Organ Sharing database in the very same eras. Our IMPACT-scores, on the other hand, seem higher than those reported by ISHLT. Survival after transplantation and conditional on 1-year survival was higher than the outcome reported by the ISHLT Registry. As our operation technique and post-transplant immunosuppressive schedule did not differ from most centers, we speculated on potential factors that might contribute to our positive results. Patient selection and a relatively short waiting time are important contributors to the overall survival benefit. Our centralized follow-up may also have played an important role. Finally, the indefinite compulsory health insurance coverage in our country and easy access to different screening programs might also have influenced our outcome in a positive way. We are well aware that with challenges like donor organ shortage, more and more patients on mechanical circulatory support (MCS) will affect outcomes in the future. ispartof: ANNALS OF CARDIOTHORACIC SURGERY vol:7 issue:1 pages:106-+ ispartof: location:China status: published

BACKGROUND: This proof-of-concept study investigated the feasibility of using biomarkers to monitor right heart pressures (RHP) in heart transplanted (HTx) patients. METHODS: In 298 patients, we measured 7.6 years post-HTx mean pressures in the right atrium (mRAP) and pulmonary artery (mPAP) and capillaries (mPCWP) along with plasma high-sensitivity troponin T (hsTnT), a marker of cardiomyocyte injury, and the multidimensional urinary classifiers HF1 and HF2, mainly consisting of dysregulated collagen fragments. RESULTS: In multivariable models, mRAP and mPAP increased with hsTnT (per 1-SD, +0.91 and +1.26 mm Hg; P < 0.0001) and with HF2 (+0.42 and +0.62 mm Hg; P ≤ 0.035), but not with HF1. mPCWP increased with hsTnT (+1.16 mm Hg; P < 0.0001), but not with HF1 or HF2. The adjusted odds ratios for having elevated RHP (mRAP, mPAP or mPCWP ≥10, ≥24, ≥17 mm Hg, respectively) were 1.99 for hsTnT and 1.56 for HF2 (P ≤ 0.005). In detecting elevated RHPs, areas under the curve were similar for hsTnT and HF2 (0.63 vs 0.65; P = 0.66). Adding hsTnT continuous or per threshold or HF2 continuous to a basic model including all covariables did not increase diagnostic accuracy (P ≥ 0.11), whereas adding HF2 per optimized threshold increased both the integrated discrimination (+1.92%; P = 0.023) and net reclassification (+30.3%; P = 0.010) improvement. CONCLUSIONS: Correlating RHPs with noninvasive biomarkers in HTx patients is feasible. However, further refinement and validation of such biomarkers is required before their clinical application can be considered. ispartof: TRANSPLANTATION DIRECT vol:4 issue:5 ispartof: location:United States status: published

Objectives Urinary Proteomics in Predicting Heart Transplantation Outcomes (uPROPHET; NCT03152422) aims: (i) to construct new multidimensional urinary proteomic (UP) classifiers that after heart transplantation (HTx) help in detecting graft vasculopathy, monitoring immune system activity and graft performance, and in adjusting immunosuppression; (ii) to sequence UP peptide fragments and to identify key proteins mediating HTx-related complications; (iii) to validate UP classifiers by demonstrating analogy between UP profiles and tissue proteomic signatures (TP) in diseased explanted hearts, to be compared with normal donor hearts; (iv) and to identify new drug targets. This article describes the uPROPHET database construction, follow-up strategies and baseline characteristics of the HTx patients. Methods HTx patients enrolled at the University Hospital Gasthuisberg (Leuven) collected mid-morning urine samples. Cardiac biopsies were obtained at HTx. UP and TP methods and the statistical work flow in pursuit of the research objectives are described in detail in the Data supplement. Results Of 352 participants in the UP study (24.4% women), 38.9%, 40.3%, 5.7% and 15.1% had ischemic, dilated, hypertrophic or other cardiomyopathy. The median interval between HTx and first UP assessment (baseline) was 7.8 years. At baseline, mean values were 56.5 years for age, 25.2 kg/m2 for body mass index, 142.3/84.8 mm Hg and 124.2/79.8 mm Hg for office and 24-h ambulatory systolic/diastolic pressure, and 58.6 mL/min/1.73 m2 for the estimated glomerular filtration rate. Of all patients, 37.2% and 6.5% had a history of mild (grade = 1B) or severe (grade ≥ 2) cellular rejection. Anti-body mediated rejection had occurred in 6.2% patients. The number of follow-up urine samples available for future analyses totals over 950. The TP study currently includes biopsies from 7 healthy donors and 15, 14, and 3 patients with ischemic, dilated, and hypertrophic cardiomyopathy. Conclusions uPROPHET constitutes a solid resources for UP and TP research in the field of HTx and has the ambition to lay the foundation for the clinical application of UP in risk stratification in HTx patients.

Background The Zwolle score is recommended to identify low-risk patients eligible for early hospital discharge after ST-elevation myocardial infarction (STEMI), but since only one third of STEMI has low Zwolle score, hospital discharge is frequently delayed. B-type natriuretic peptide (BNP) also provides prognostic information after STEMI. The aim of the study was to test the hypothesis that patients with high Zwolle score associated with low BNP share similar outcomes than those with low Zwolle score. Methods and results The study population consisted of 1032 consecutive STEMI patients in whom BNP was measured 24h after chest pain onset. The area under the curve of Zwolle score and plasma BNP for 30-day mortality were 0.82 and 0.87, p=0.39. A BNP threshold of 200pg/ml had sensitivity of 100% and specificity of 34% for predicting 30-day mortality. Patients with high Zwolle score and BNP≤200pg/ml (n=183) had similar mortality and hospital stay to those with low Zwolle score (0% vs. 0.5% and 5 vs. 5days, both p=1.0). By contrast, patients with high Zwolle score and BNP>200pg/ml had the highest mortality (6.7%) and the longest hospital stay (6days), both p Conclusion STEMI patients with high Zwolle score but low BNP share similar outcomes with those with low Zwolle score and should be eligible for early discharge. Hence, using the rule of "low-Zwolle or low-BNP" might increase the number of STEMI patients that might be eligible for early discharge.
