Background: Single high-sensitivity troponin T (hs-TnT) measurement is predictive of cardiac events in adults with congenital heart disease (ACHD). We aimed to study the prognostic value of serial hs-TnT measurements in stable patients with ACHD. Methods: In total, 602 consecutive patients with ACHD were enrolled in this prospective study (2011-2013). Blood sampling was performed at enrollment and thereafter yearly during scheduled visits, up to 4 years. Hs-TnT, N-terminal pro B-type natriuretic peptide (NT-proBNP), and estimated glomerular filtration rate (eGFR) were measured. The composite primary endpoint was defined as all-cause mortality, heart failure, arrhythmia, hospitalization, cardiac (re)interventions, or thromboembolic events. The relationship between changes in serial hs-TnT and the primary endpoint was studied by joint models with adjustment for repeated NT-proBNP and eGFR. Results: In 601 patients (median age, 33 [interquartile range, 25-41] years, 42% women, 90% NYHA I), at least 1 hs-TnT measurement was performed; a mean of 4.3 hs-TnT measurements per patient were collected. After a median follow-up of 5.8 [interquartile range, 5.3-6.3] years, 229 (38.1%) patients reached the primary endpoint. On average, hs-TnT levels increased over time, and more in patients who reached the primary endpoint (P < 0.001). A 2-fold higher hs-TnT was associated with the primary endpoint (unadjusted hazard ratio, 1.62; 95% confidence interval, 1.44-1.82; P < 0.001). The association remained after adjustment for repeated eGFR but not when adjusted for repeated NT-proBNP; repeated NT-proBNP remained associated with the primary endpoint. Conclusion: In stable patients with ACHD, hs-TnT levels increased before the occurrence of an event and repeated hs-TnT was associated with the risk of adverse cardiac events. However, repeated hs-TnT was not superior to repeated NT-proBNP., Contexte : Le dosage unique de la troponine T hypersensible (hs-TnT) est predictif d ’ev enements cardiaques chez les adultes atteints de cardiopathie congenitale.

Background: We sought to assess the effects of percutaneous atrial septal defect (ASD) closure on blood biomarker levels that possibly reflect reverse cardiac remodeling. Therefore, this study investigated temporal changes in six blood biomarkers following percutaneous ASD closure in adults. Methods: In this prospective observational cohort study, adults with ASD type II scheduled for percutaneous closure were included (2012–2016). N

Objective Soluble suppression of tumourigenicity-2 (sST2) is upregulated as response to myocardial stress and may be a potential biomarker for risk stratification in patients with adult congenital heart disease (ACHD). This study aimed to investigate the release of sST2 and its association with cardiovascular events in ACHD. Methods In this prospective cohort study, 602 consecutive patients with ACHD visiting the outpatient clinic were included (2011–2013). The association between sST2 and a primary composite endpoint of all-cause mortality, heart failure, hospitalisation, arrhythmia, thromboembolic events or cardiac interventions was investigated using multivariable Cox regression. Results sST2 was measured in 590 (98%) patients (median age 33 [25–41] years, 42% women). After a median follow-up of 5.8 [IQR 5.1–6.2) years, 225 (38.5%) reached the primary endpoint. sST2 was significantly associated wit

16 april 2018, Contains fulltext : 190533.pdf (Publisher’s version ) (Open Access), BACKGROUND: Red cell distribution width (RDW) is a standard component of the automated blood count, and is of prognostic value in heart failure and coronary heart disease. We investigated the association between RDW and cardiovascular events in patients with adult congenital heart disease (ACHD). METHODS AND RESULTS: In this prospective cohort study, 602 consecutive patients with ACHD who routinely visited the outpatient clinic were enrolled between 2011 and 2013. RDW was measured in fresh venous blood samples at inclusion in 592 patients (median age 33 [IQR 25-41] years, 58% male, 90% NYHA I) and at four annual follow-up visits. During 4.3 [IQR 3.8-4.7] years of follow-up, the primary endpoint (death, heart failure, hospitalization, arrhythmia, thromboembolic events, cardiac intervention) occurred in 196 patients (33%). Median RDW was 13.4 (12.8-14.1)% versus 12.9 (12.5-13.4)% in patients with and without the primary endpoint (P<0.001). RDW was significantly associated with the endpoint when adjusted for age, sex, clinical risk factors, CRP, and NT-proBNP (HR 1.20; 95% CI 1.06-1.35; P=0.003). The C-index of the model including RDW was slightly, but significantly (P=0.005) higher than the model without (0.74, 95% CI 0.70-0.78 versus 0.73, 95% CI 0.69-0.78). Analysis of repeated RDW measurements (n=2449) did not show an increase in RDW prior to the occurrence of the endpoint. CONCLUSIONS: RDW is associated with cardiovascular events in patients with ACHD, independently of age, sex, clinical risk factors, CRP, and NT-proBNP. This readily available biomarker could therefore be considered as an additive biomarker for risk stratification in these patients.

Background--A single NT-proBNP (N-terminal pro-B-type natriuretic peptide) measurement is a strong prognostic factor in adult congenital heart disease. This study investigates NT-proBNP profiles within patients with adult congenital heart disease and relates these to cardiovascular events. Methods and Results--In this prospective cohort, 602 patients with adult congenital heart disease were enrolled at the outpatient clinic (years 2011-2013). NT-proBNP was measured at study inclusion in 595 patients (median age 33 [IQR 25-41] years, 58% male, 90% NYHA I) and at subsequent annual visits. The primary end point was defined as death, heart failure, hospitalization, arrhythmia, thromboembolic event, or cardiac intervention; the secondary end point as death or heart failure. Repeated measurements were analyzed using linear mixed models and joint models. During a median follow-up of 4.4 [IQR 3.8-4.8] years, a total of 2424 repeated measurements were collected. Average NT-proBNP increase was 2.9 pmol/L the year before the primary end point (n=199, 34%) and 18.2 pmol/L before the secondary end point (n=58, 10%), compared with 0.3 pmol/L in patients who remained end point-free (P-value for difference in slope 0.006 and < 0.0

Context Matrix metalloproteinases (MMPs) are associated with diastolic dysfunction and heart failure in acquired heart disease. Objective To investigate the role of MMPs as novel biomarkers in clinically stable adults with congenital heart disease. Methods We measured serum MMP-2, -3, -9 and tissue inhibitor of matrix metalloproteinase-1 in 425 patients and analysed the association with cardiac function and exercise capacity. Results MMP-2 was significantly associated with exercise capacity, ventilatory efficiency and left ventricular deceleration time, independently of age, sex, body surface area and NT-proBNP. Conclusion MMP-2 may provide new information in the clinical evaluation of adults with congenital heart disease.

Despite successful aortic coarctation (CoA) repair, systemic hypertension often recurs which may influence left ventricular (LV) function. We aimed to detect early LV dysfunction using LV global longitudinal strain (GLS) in adults with repaired CoA, and to identify associations with patient and echocardiographic characteristics. In this cross-sectional study, patients with repaired CoA and healthy controls were recruited prospectively. All subjects underwent echocardiography, ECG and blood sampling within 1 day. With speckle-tracking echocardiography, we assessed LV GLS on the apical four-, three- and two-chamber views. We included 150 subjects: 75 patients (57 % male, age 33.4 ± 12.8 years, age at repair 2.5 [IQR: 0.1–11.1] years) and 75 healthy controls of similar sex and age. LV GLS was lower

__Abstract__ Congenital heart disease (ConHD) is the most common congenital abnormality in newborns, with a birth prevalence of 9 per 1000 live births.2 ConHD comprises a number of cardiac abnormalities with varying aetiology which can be divided into simple, moderate and complex disease (Table 1). The eight most common ConHD are ventricular septal defect (34%), atrial septal defect (13%), persistent ductus arteriosus (10%), pulmonary stenosis (8%), tetralogy of Fallot (ToF, 5%), aortic coarctation (5%), transposition of the great arteries (TGA, 5%) and aortic stenosis (4%). With the introduction of open-heart surgery, and the use of cardiopulmonary bypass (heart-lung machine) life expectancy of ConHD patients has remarkably improved. Before these techniques became available half of the new-borns with ConHD died during the first decade of life. Improvements over the last decades in cardiac surgery, anaesthesia, intensive care and specialized congenital cardiologist care have led to a steadily growing number of adult patients with ConHD, in particular those patients with more complex ConHD. The estimated number of adults with ConHD in the Netherlands is 35.000 currently.

Background Amino-terminal B-type natriuretic peptide (NT-proBNP) may detect early cardiac dysfunction in adults with tetralogy of Fallot (ToF) late after corrective surgery. We aimed to determine the value of NT-proBNP in adults with ToF and establish its relationship with echocardiography and exercise capacity. Methods and results NT-proBNP measurement, electrocardiography and detailed 2D-echocardiography were performed on the same day in 177 consecutive adults with ToF (mean age 34.6 ± 11.8 years, 58% male, 89% NYHA I, 29.3

Aims To describe long-term survival, clinical outcome and ventricular systolic function in a longitudinally followed cohort of patients after Mustard repair for transposition of the great arteries (TGA). There is serious concern about the long-term outcome after Mustard repair. Methods and results This longitudinal single-centre study consisted of 91 consecutive patients, who underwent Mustard repair before 1980, at age <15 years, and were evaluated in-hospital every 10 years. Survival status was obtained of 86 patients. Median follow-up was 35 (IQR 34-38) years. Cumulative survival was 84% after 10 years, 80% after 20 years, 77% after 30 years, and 68% after 39 years. Cumulative survival free of events (i.e. heart transplantation, arrhythmias, reintervention, and heart failure) was 19% after 39 years. Reinterventions were mainly required for baffle-related problems. Supraventricular and ventricular arrhythmias occurred in 28 and 6% of the patients, respectively. Pacemaker and/or ICD implantation was performed in 39%. Fifty survivors participated in the current in-hospital investigation including electrocardiography, 2D-echocardiography, cardiopulmonary-exercise testing, NT-proBNP measurement, Holter monitoring, and cardiac magnetic resonance. Right ventricular systolic function was impaired in all but one patient at last follow-up, and 14% developed heart failure in the last decade. NT-proBNP levels [median 31.6 (IQR 22.3-53.2) pmol/L] were elevated in 92% of the patients. Early postoperative arrhythmias were a predictor for late arrhythmias [HR 3.8 (95% CI 1.5-9.5)], and development of heart failure [HR 8.1 (95% CI 2.2-30.7)]. Also older age at operation was a predictor for heart failure [HR 1.26 (95% CI 1.0-1.6)]. Conclusion Long-term survival after Mustard repair is clearly diminished and morbidity is substantial. Early postoperative arrhythmia

Brain natriuretic peptide and N-terminal pro-brain natriuretic peptide are two well-established

Brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) are well-established markers for heart failure in the general population. However, the value of BNP as a diagnostic and prognostic marker for patients with structural congenital heart disease (CHD) is still unclear. Therefore, the purpose of this study was to evaluate the clinical utility of BNP in patients with CHD. We executed a PubMed literature search and included 49 articles that focused on complex congenital heart defects such as tetralogy of Fallot, systemic right ventricle, and univentricular hearts. Data on BNP measurements and cardiac function parameters were extracted. In all patients after correction for tetralogy of Fallot, BNP levels were elevated and correlated significantly with right ventricular end-diastolic dimensions and severity of pulmonary valve regurgitation. Patients with a systemic right ventricle had elevated BNP levels, and positive correlations between BNP and right ventricular function were seen. In patients with a univentricular heart, elevated BNP levels were observed before completion of the Fontan circulation or when patients were symptomatic; a clear association between BNP and New York Heart Association functional class was demonstrated. In conclusion, this review shows an

Aims: We aim to investigate the association between different types of statins, in particular simvastatin and atorvastatin, and long-term mortality after percutaneous coronary intervention (PCI). Methods and results: Between 2000 and 2005, a prospective cohort was constituted of 5,647 patients who underwent PCI. Type and doses of statin use were collected after the PCI procedure. Survival status was obtained from municipal civil registries. The primary endpoint was all-cause mortality. Secondary endpoints were cardiac and cancer mortality. Median follow-up was 5.0 years (range three to nine years). During follow- up 738 patients (13.1%) died. In total, 4,970 patients (88%) were on statin therapy four weeks after PCI of whom the majority used either atorvastatin (34%) or simvastatin (29%). Cumulative survival rates at eight years in the atorvastatin group were 83%, and 79% in the simvastatin group (log-rank, p=0.004). After adjustment, statin use was associated with a 50% mortality reduction (HR 0.49, 95%CI 0.40-0.59) and atorvastatin use was associated with lower total mortality than simvastatin use (adjusted HR 0.77, 95% CI 0.61-0.97). This was largely driven by cancer mortality (adjusted HR 0.59, 95%CI 0.38-0.91). Conclusions: In patients undergoing PCI the use of statins is associated with reduced mortality during prolonged follow-up. Patients using atorvastatin had a 23% lower mortality than those using simvastatin.
