- AIMS: Reflecting both increased venous pressure and reduced cardiac output, abnormal liver tests are common in patients with severe heart failure and are associated with adverse clinical outcomes. We aimed to investigate the prognostic significance of abnormal liver tests in ambulatory patients with heart failure with reduced ejection fraction (HFrEF), explore any treatment interaction between bilirubin and sodium- glucose cotransporter 2 (SGLT2) inhibitors and examine change in liver tests with SGLT2 inhibitor treatment. METHODS AND RESULTS: We explored these objectives in the Dapagliflozin And Prevention of Adverse outcomes in Heart Failure (DAPA-HF) trial, with focus on bilirubin. We calculated the incidence of cardiovascular death or worsening heart failure by bilirubin tertile. Secondary cardiovascular outcomes were examined, along with the change in liver tests at the end-of-study visit. Baseline bilirubin was available in 4720 patients (99.5%). Participants in the highest bilirubin tertile (T3) have more severe HFrEF (lower left ventricular ejection fraction, higher N-terminal pro-B-type natriuretic peptide [NT-proBNP] and worse New York Heart Association class), had a greater burden of atrial fibrillation but less diabetes. Higher bilirubin (T3 vs. T1) was associated with worse outcomes even after adjustment for other predictive variables, including NT-proBNP and troponin T (adjusted hazard ratio for the primary outcome 1.73 [95% confidence interval 1.37-2.17], p $<$ 0.001; and 1.52 [1.12-2.07], p = 0.01 for cardiovascular death). Baseline bilirubin did not modify the benefits of dapagliflozin. During follow-up, dapagliflozin had no effect on liver tests. CONCLUSION: Bilirubin concentration was an independent predictor of worse outcomes but did not modify the benefits of dapagliflozin in HFrEF. Dapagliflozin was not associated with change in liver tests. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT03036124.

Journal article (peer-reviewed)abstract
- Background: Predicting mortality is important in patients with heart failure (HF). However, current strategies for predicting risk are only modestly successful, likely because they are derived from statistical analysis methods that fail to capture prognostic information in large data sets containing multi-dimensional interactions. Methods and results: We used a machine learning algorithm to capture correlations between patient characteristics and mortality. A model was built by training a boosted decision tree algorithm to relate a subset of the patient data with a very high or very low mortality risk in a cohort of 5822 hospitalized and ambulatory patients with HF. From this model we derived a risk score that accurately discriminated between low and high-risk of death by identifying eight variables (diastolic blood pressure, creatinine, blood urea nitrogen, haemoglobin, white blood cell count, platelets, albumin, and red blood cell distribution width). This risk score had an area under the curve (AUC) of 0.88 and was predictive across the full spectrum of risk. External validation in two separate HF populations gave AUCs of 0.84 and 0.81, which were superior to those obtained with two available risk scores in these same populations. Conclusions: Using machine learning and readily available variables, we generated and validated a mortality risk score in patients with HF that was more accurate than other risk scores to which it was compared. These results support the use of this machine learning approach for the evaluation of patients with HF and in other settings where predicting risk has been challenging.

Journal article (peer-reviewed)abstract
- Heart failure (HF) is a common condition with which high mortality, morbidity, and poor quality of life are associated. It has previously been shown that use of HF management programmes (HFMPs) in HF clinics can be beneficial. The purpose of this study was to evaluate if the use of HFMPs also has beneficial effects on HF patients in primary healthcare (PHC). less thanbrgreater than less thanbrgreater thanThis is a randomized, prospective, open-label study including 160 patients from five PHC centres with systolic HF and a mean age of 75 years (standard deviation 7.8). In the intervention group, an intensive follow-up was performed by HF nurses and physicians providing information and education about HF and the optimization of HF treatment according to recognized guidelines. There was a significant improvement of composite endpoints in the intervention group. Significantly more patients with reduced N-terminal pro brain natriuretic peptide (P 0.012), improved cardiac function (P 0.03), fewer healthcare contacts (P 0.04), and fewer emergency room visits and admittances (P 0.0002 and P 0.03, respectively) could be seen in the intervention group when compared with the control group. less thanbrgreater than less thanbrgreater thanThe use of a HFMP in a PHC setting was found to have beneficial effects in terms of reducing the number of healthcare contacts and hospital admissions, and improving cardiac function in patients with systolic HF, even if the result should be interpreted with caution. It can therefore be recommended that HFMPs should be used in PHC.

Research review (peer-reviewed)abstract
- In patients with heart failure, the beneficial effects of drug and device therapies counteract to some extent ongoing cardiac damage. According to the net balance between these two factors, cardiac geometry and function may improve (reverse remodelling, RR) and even completely normalize (remission), or vice versa progressively deteriorate (adverse remodelling, AR). RR or remission predict a better prognosis, while AR has been associated with worsening clinical status and outcomes. The remodelling process ultimately involves all cardiac chambers, but has been traditionally evaluated in terms of left ventricular volumes and ejection fraction. This is the second part of a review paper by the Study Group on Biomarkers of the Heart Failure Association of the European Society of Cardiology dedicated to ventricular remodelling. This document examines the proposed criteria to diagnose RR and AR, their prevalence and prognostic value, and the variables predicting remodelling in patients managed according to current guidelines. Much attention will be devoted to RR in patients with heart failure with reduced ejection fraction because most studies on cardiac remodelling focused on this setting.

Journal article (peer-reviewed)abstract
- Aims N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity troponin T (hs-TnT) and soluble suppression of tumorigenesis-2 (sST2) predict outcome in chronic heart failure (HF). We assessed the influence of age on circulating levels and prognostic significance of these biomarkers. Methods and results Individual data from 5301 patients with chronic HF and NT-proBNP, hs-TnT, and sST2 data were evaluated. Patients were stratified according to age: <60 years (n = 1332, 25%), 60-69 years (n = 1628, 31%), 70-79 years (n = 1662, 31%), and >= 80 years (n = 679, 13%). Patients (median age 66 years, 75% men, median left ventricular ejection fraction 28%, 64% with ischaemic HF) had median NT-proBNP 1564 ng/L, hs-TnT 21 ng/L, and sST2 29 ng/mL. Age independently predicted NT-proBNP and hs-TnT, but not sST2. The best NT-proBNP and hs-TnT cut-offs for 1-year and 5-year all-cause and cardiovascular mortality and 1- to 12-month HF hospitalization increased with age, while the best sST2 cut-offs did not. When stratifying patients according to age- and outcome-specific cut-offs, this stratification yielded independent prognostic significance over NT-proBNP levels only, or the composite of NT-proBNP and hs-TnT, and improved risk prediction for most endpoints. Finally, absolute NT-proBNP, hs-TnT, and sST2 levels predicted outcomes independent of age, sex, left ventricular ejection fraction category, ethnic group, and other variables. Conclusions Soluble ST2 is less influenced by age than NT-proBNP or hs-TnT; all these biomarkers predict outcome regardless of age. The use of age- and outcome-specific cut-offs of NT-proBNP, hs-TnT and sST2 allows more accurate risk stratification than NT-proBNP alone or the combination of NT-proBNP and hs-TnT.

Journal article (peer-reviewed)abstract
- Aims: To develop a suite of quality indicators (QIs) for the evaluation of the care and outcomes for adults with pulmonary arterial hypertension (PAH). Methods and results: We followed the European Society of Cardiology (ESC) methodology for the development of QIs. This included (i) the identification of key domains of care for the management of PAH, (ii) the proposal of candidate QIs following systematic review of the literature, and (iii) the selection of a set of QIs using a modified Delphi method. The process was undertaken in parallel with the writing of the 2022 ESC/European Respiratory Society (ERS) guidelines for the diagnosis and treatment of pulmonary hypertension and involved the Task Force chairs, experts in PAH, Heart Failure Association (HFA) members and patient representatives. We identified five domains of care for patients with PAH: structural framework, diagnosis and risk stratification, initial treatment, follow-up, and outcomes. In total, 23 main and one secondary QIs for PAH were selected. Conclusion: This document presents the ESC QIs for PAH, describes their development process and offers scientific rationale for their selection. The indicators may be used to quantify and improve adherence to guideline-recommended clinical practice and improve patient outcomes.

Journal article (peer-reviewed)abstract
- The evaluation of natriuretic peptides has become increasingly valuable in a clinical setting, where information is often needed promptly. Objectives: To compare the usefulness of the recently released Roche Cardiac Reader ® NT-proBNP assay against the Roche Elecsys® NT-proBNP laboratory system in a clinical setting. Design and Results: Blood samples from 440 patients admitted for acute coronary syndromes, worsening of heart failure, or as policlinic heart failure patients were evaluated. The relation between the assays was analysed and the diagnostic concordance calculated. A good correlation was found between the assays (r=0.96, 95% CI: 0.94-0.97) with a diagnostic concordance of 0.93. A separate analysis was performed in the range where most clinical decisions are made (60-3000 ng/L), with a diagnostic concordance of 88%. The usefulness in a clinical setting where time is important was high. Conclusion: The Roche Cardiac Reader® NT-proBNP assay has been evaluated in a clinical setting. The point-of-care method shows good results, although with a restricted analytical range compared with the reference.

Journal article (peer-reviewed)abstract
- AIMS: Abnormal liver function tests (LFTs) are common in ambulatory heart failure (HF). The aim of this study was to characterize abnormal LFTs during index hospitalization. METHODS AND RESULTS: A post-hoc analysis was carried out of the placebo group of the EVEREST (Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan) trial, which enrolled patients hospitalized for HF with an ejection fraction (EF) 34 IU/L), alanine transaminase (ALT, >34 IU/L), alkaline phosphatase (AP, >123 IU/L),gamma-glutamyl transferase (GGT, >50 IU/L), and total bilirubin (T Bili, >1.2 mg/dL) were measured at baseline, discharge/day 7, and post-discharge. Co-primary endpoints were all-cause mortality (ACM) and cardiovascular mortality or first HF hospitalization (CVM + HFH). Study participants had a mean age of 65.6 +/-12.0 years, were mostly male, reported high prevalences of medical co-morbidities, and were well treated with evidence-based therapies. Baseline LFT abnormalities were common (ALB 17%, AST 21%, ALT 21%, AP 23%, GGT 62%, and T Bili 26%). Abnormal T Bili was the only marker to decrease substantially from baseline (26%) to discharge/day 7 (19%). All LFTs, except AP, improved post-discharge. Lower baseline ALB and elevated T Bili were associated with higher rates of ACM, and in-hospital decreases in ALB and increases in T Bili were associated with higher rates of both ACM and CVM + HFH. CONCLUSION: LFT abnormalities are common during hospitalization for HF in patients with reduced EF and were persistent at discharge. Baseline and in-hospital changes in ALB and T Bili provide additional prognostic value.

A risk score for predicting 30-day mortality in heart failure patients undergoing non-cardiac surgery
- 2014

Journal article (peer-reviewed)abstract
- BackgroundHeart failure is an established risk factor for poor outcomes in patients undergoing non-cardiac surgery, yet risk stratification remains a clinical challenge. We developed an index for 30-day mortality risk prediction in this particular group. Methods and resultsAll individuals with heart failure undergoing non-cardiac surgery between October 23 2004 and October 31 2011 were included from Danish administrative registers (n=16827). In total, 1787 (10.6%) died within 30days. In a simple risk score based on the variables from the revised cardiac risk index, plus age, gender, acute surgery, and body mass index category the following variables predicted mortality (points): male gender (1), age 56-65years (2), age 66-75years (4), age 76-85years (5), or age >85years (7), being underweight (4), normal weight (3), or overweight (1), undergoing acute surgery (5), undergoing high-risk procedures (intra-thoracic, intra-abdominal, or suprainguinal aortic) (3), having renal disease (1), cerebrovascular disease (1), and use of insulin (1). The c-statistic was 0.79 and calibration was good. Mortality risk ranged from <2% for a score <5 to >50% for a score 20. Internal validation by bootstrapping (1000 re-samples) provided c-statistic of 0.79. A more complex risk score based on stepwise logistic regression including 24 variables at P<0.05 performed only slightly better, c-statistic=0.81, but was limited in use by its complexity. ConclusionsFor patients with heart failure, this simple index can accurately identify those at low risk for perioperative mortality.
