Aims In patients with heart failure (HF), hospitalization rates are increasing, particularly for non-HF causes and over half may be avoidable. Self-monitoring of symptoms plays a key part in the early identification of deterioration. Our objective was to develop expert consensus for a core outcome set (COS) of symptoms to be monitored by patients, using validated single-item patient-reported outcome measures (PROMs), focused on the key priority of reducing admissions in HF. Methods and results A rigorous COS development process incorporating systematic review, modified e-Delphi and nominal group technique (NGT) methods. Participants included 24 HF patients, 4 carers, 29 HF nurses, and 9 doctors. In three Delphi and NGT rounds, participants rated potential outcomes on their importance before a HF or a non-HF admission using a 5-point Likert scale. Opinion change between rounds was assessed and a two-thirds threshold was used for outcome selection. Item generation using systematic review identified 100 validated single-item PROMs covering 34 symptoms or signs, relevant to admission for people with HF. De-duplication and formal consensus processes, resulted in a COS comprising eight symptoms and signs; shortness of breath, arm or leg swelling, abdomen bloating, palpitations, weight gain, chest pain, anxiety, and overall health. In the NGT, a numerical rating scale was selected as the optimal approach to symptom monitoring. Conclusion Recognition of a range of HF-specific and general symptoms, alongside comorbidities, is an important consideration for admission prevention. Further work is needed to validate and integrate the COS in routine care with the aim of facilitating faster identification of clinical deterioration.

Objectives This study examined the effects of sacubitril/valsartan on N-terminal pro–B-type natriuretic peptide (NT-proBNP) levels and determined patient characteristics associated with favorable NT-proBNP reduction response. Background NT-proBNP levels reflect cardiac wall stress and predict event risk in patients with acute decompensated heart failure (ADHF). Methods Post-hoc analysis of the TRANSITION (Comparison of Pre- and Post-discharge Initiation of Sacubitril/Valsartan Therapy in HFrEF Patients After an Acute Decompensation Event) study, including stabilized ADHF patients with reduced ejection fraction, randomized to open-label sacubitril/valsartan initiation in-hospital (pre-discharge) versus post-discharge. NT-proBNP was measured at randomization (baseline), discharge, and 4 and 10 weeks post-randomization. A favorable NT-proBNP response was defined as reduction to ≤1,000 pg/ml or >30% from baseline. Results In patients receiving sacubitril/valsartan in-hospital, NT-proBNP was reduced by 28% at discharge, with 46% of patients obtaining favorable NT-proBNP reduction response compared with a 4% reduction and 18% favorable response rate in patients initiated post-discharge (p Conclusions In-hospital initiation of sacubitril/valsartan produced rapid reductions in NT-proBNP, statistically significant at discharge. A favorable NT-proBNP response over time was associated with a better prognosis and predicted by higher starting dose and predisposing clinical profile.

Strain assessment allows accurate evaluation of myocardial function and mechanics in ST-segment elevation myocardial infarction (STEMI). Strain using cardiovascular magnetic resonance (CMR) has traditionally been assessed with tagging but limitations of this technique have led to more widespread use of alternative methods, which may be more robust. We compared the inter-study repeatability of circumferential global peak-systolic strain (Ecc) and peak-early diastolic strain rate (PEDSR) derived by tagging with values obtained using novel cine-based software: Feature Tracking (FT) (TomTec, Germany) and Tissue Tracking (TT) (Circle cvi42, Canada) in patients following STEMI. Twenty male patients (mean age 56 ± 10 years, mean infarct size 13.7 ± 7.1% of left ventricular mass) were randomised to undergo CMR 1–5 days post-STEMI at 1.5 T or 3.0 T, repeated after ten minutes at the same field strength. Ecc and PEDSR were assessed using tagging, FT and TT. Inter-study repeatability was evaluated using Bland–Altman analyses, coefficients of variation (CoV) and intra-class correlation coefficient (ICC). Ecc (%) was significantly lower with tagging than with FT or TT at 1.5 T (− 9.5 ± 3.3 vs. − 17.5 ± 3.8 vs. −15.5 ± 5.2, respectively, p −1): 1.5 T (0.6 ± 0.2 vs. 1.5 ± 0.4 vs. 1.0 ± 0.4, for tagging, FT and TT respectively, p Ecc at 1.5 T was good for tagging and excellent for FT and TT: CoV 16.7%, 6.38%, and 8.65%, respectively. Repeatability for Ecc at 3.0 T was good for all three techniques: CoV 14.4%, 11.2%, and 13.0%, respectively. However, repeatability of PEDSR was generally lower than that for Ecc at 1.5 T (CoV 15.1%, 13.1%, and 34.0% for tagging, FT and TT, respectively) and 3.0 T (CoV 23.0%, 18.6%, and 26.2%, respectively). Following STEMI, Ecc and PEDSR are higher when measured with FT and TT than with tagging. Inter-study repeatability of Ecc is good for tagging, excellent for FT and TT at 1.5 T, and good for all three methods at 3.0 T. The repeatability of PEDSR is good to moderate at 1.5 T and moderate at 3.0 T. Cine-based methods to assess Ecc following STEMI may be preferable to tagging.

The EMPEROR-Preserved trial showed that the sodium–glucose co-transporter 2 inhibitor empagliflozin significantly reduces the risk of cardiovascular death or hospitalization for heart failure (HHF) in heart failure patients with left ventricular ejection fraction (LVEF) > 40%. Here, we report the results of a pre-specified analysis that separately evaluates these patients stratified by LVEF: preserved (≥ 50%) (n = 4,005; 66.9%) or mid-range (41–49%). In patients with LVEF ≥ 50%, empagliflozin reduced the risk of cardiovascular death or HHF (the primary endpoint) by 17% versus placebo (hazard ratio (HR) 0.83; 95% confidence interval (CI): 0.71–0.98, P = 0.024). For the key secondary endpoint, the HR for total HHF was 0.83 (95%CI: 0.66–1.04, P = 0.11). For patients with an LVEF of 41–49%, the HR for empagliflozin versus placebo was 0.71 (95%CI: 0.57–0.88, P = 0.002) for the primary outcome (Pinteraction = 0.27), and 0.57 (95%CI: 0.42–0.79, P Pinteraction = 0.06). These results, together with those from the EMPEROR-Reduced trial in patients with LVEF

Item does not contain fulltext BACKGROUND: Sodium-glucose cotransporter 2 inhibitors reduce the risk of hospitalization for heart failure in patients with heart failure and a reduced ejection fraction, but their effects in patients with heart failure and a preserved ejection fraction are uncertain. METHODS: In this double-blind trial, we randomly assigned 5988 patients with class II-IV heart failure and an ejection fraction of more than 40% to receive empagliflozin (10 mg once daily) or placebo, in addition to usual therapy. The primary outcome was a composite of cardiovascular death or hospitalization for heart failure. RESULTS: Over a median of 26.2 months, a primary outcome event occurred in 415 of 2997 patients (13.8%) in the empagliflozin group and in 511 of 2991 patients (17.1%) in the placebo group (hazard ratio, 0.79; 95% confidence interval [CI], 0.69 to 0.90; P

Nonadherence to antihypertensive treatment is a critical contributor to suboptimal blood pressure control. There are limited and heterogeneous data on the risk factors for nonadherence because few studies used objective-direct diagnostic methods. We used high-performance liquid chromatography-tandem mass spectrometry of urine and serum to detect nonadherence and explored its association with the main demographic- and therapy-related factors in 1348 patients with hypertension from 2 European countries. The rates of nonadherence to antihypertensive treatment were 41.6% and 31.5% in the UK and Czech populations, respectively. Nonadherence was inversely related to age and male sex. Each increase in the number of antihypertensive medications led to 85% and 77% increase in nonadherence ( P P ≤0.005 in both populations). The predictive model for nonadherence, including age, sex, diuretics, and the number of prescribed antihypertensives, showed area under the curves of 0.758 and 0.710 in the UK and Czech populations, respectively. The area under the curves for the UK model tested on the Czech data and for the Czech model tested on UK data were calculated at 0.708 and 0.756, respectively. We demonstrate that the number and class of prescribed antihypertensives are modifiable risk factors for biochemically confirmed nonadherence to blood pressure–lowering therapy. Further development of discriminatory models incorporating these parameters might prove clinically useful in assessment of nonadherence in countries where biochemical analysis is unavailable.

Although most patients in the PARADIGM-HF (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) trial had mild symptoms, there is a poor correlation between reported functional limitation and prognosis in heart failure.The aim of this study was to examine the spectrum of risk in PARADIGM-HF and the effect of LCZ696 across that spectrum.This study analyzed rates of the primary composite outcome of cardiovascular death or heart failure hospitalization, its components, and all-cause mortality using the MAGGIC (Meta-Analysis Global Group in Chronic Heart Failure) and EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure) risk scores to categorize patients. The authors determined whether risk, on the basis of these scores, modified the treatment effect of LCZ696.The complete MAGGIC risk score was available for 8,375 of the 8,399 patients in PARADIGM-HF. The median MAGGIC score was 20 (IQR: 16 to 24). An increase of 1 point was associated with a 6% increased risk for the primary endpoint (p 0.001) and a 7% increased risk for cardiovascular death (p 0.001). The benefit of LCZ696 over enalapril for the primary endpoint was similar across the spectrum of risk (p = 0.159). Treating 100 patients for 2 years with LCZ696 instead of enalapril led to 7 fewer patients in the highest quintile of risk experiencing primary outcomes, compared with 3 in the lowest quintile. Analyses using the EMPHASIS-HF risk score gave similar findings.Although most PARADIGM-HF patients had mild symptoms, many were at high risk for adverse outcomes and obtained a large absolute benefit from LCZ696, compared with enalapril, over a relatively short treatment period. LCZ696's benefit was consistent across the spectrum of risk.

Aim: To investigate the relationship between heart rate and survival in patients with heart failure (HF) and coexisting atrial fibrillation (AF). Methods and Results: Patients with AF included in the Meta-analysis Global Group in Chronic Heart Failure (MAGGIC) meta-analysis were the main focus of this analysis (3259 patients from 17 studies). The outcome was all-cause mortality at 3 years. Heart rate was analysed as a categorical (tertiles; T1 ≤77 b.p.m., T2 78–98 b.p.m., T3 ≥98 b.p.m.) and continuous variable. Cox proportional hazard models were used to compare the risk of all-cause death between tertiles of baseline heart rate. Patients in the highest tertile were more often female, less likely to have an ischaemic aetiology or diabetes, had a lower ejection fraction but higher blood pressure and New York Heart Association (NYHA) class. Higher heart rate was associated with higher mortality in patients with sinus rhythm (SR) but not in those in AF. In patients with heart failure and reduced ejection fraction (HF-REF) and AF, death rates per 100 patient years were lowest in the highest heart rate tertile (T1 18.9 vs. T3 15.9) but this difference was not statistically significant (P = 0.10). In patients with heart failure and preserved ejection fraction (HF-PEF), death rates per 100 patient years were highest in the highest heart rate tertile (T1 14.6 vs. T3 16.0, P = 0.014). However, after adjustment for other important prognostic variables, higher heart rate was no longer associated with higher mortality in HF-PEF (or HF-REF). Conclusions: In this meta-analysis of patients with HF, heart rate does not have the same prognostic significance in patients in AF as it does in those in SR, irrespective of ejection fraction or treatment with beta-blocker.

For most patients with heart failure, treatment will now include a diuretic, an ACE inhibitor or angiotensin-II inhibitor and a beta-blocker.

This study sought to assess the prognostic impact of midregional pro-adrenomedullin (MR-proADM) after an acute myocardial infarction (AMI).Adrenomedullin (ADM) is elevated in heart failure (HF) and after AMI. Another part of its precursor, MR-proADM, is more stable in circulation and ex vivo. We investigated the cardiovascular prognostic value after AMI of MR-proADM and compared it with N-terminal pro-B-type natriuretic peptide (NTproBNP), a marker of death and HF.We measured plasma MR-proADM and NTproBNP in 983 consecutive post-AMI patients (721 men, mean age 65.0 +/- 12.2 years), 3 to 5 days after chest pain onset.There were 101 deaths and 49 readmissions with HF during follow-up (median 342, range 0 to 764 days). The MR-proADM was increased in patients with death or HF compared with survivors (median 1.19 nmol/l, range 0.09 to 5.39 nmol/l, vs. 0.71 nmol/l, range 0.25 to 6.66 nmol/l, p0.0001). Using a multivariate binary logistic model, log MR-proADM (odds ratio 4.22) and log NTproBNP (odds ratio 3.20) were significant independent predictors of death or HF (with creatinine, age, gender, and history of AMI). The areas under the receiver-operating characteristic curve for MR-proADM, NTproBNP, and the logistic model with both markers were 0.77, 0.79, and 0.84 respectively. Cox models for the predictors of death or HF showed the same variables (including log MR-proADM, hazard ratio 3.63; log NTproBNP, hazard ratio 2.67). The MR-proADM provided further risk stratification in those patients who had NTproBNP levels above the median (p0.0001). Findings were similar for death and HF as individual end points.The ADM system is activated after AMI. The MR-proADM is a powerful predictor of adverse outcome, especially in those with an elevated NTproBNP. The MR-proADM may represent a clinically useful marker of prognosis after AMI.
