- BACKGROUND: Conventional composite outcomes in heart failure (HF) trials, for example, time to cardiovascular death or first HF hospitalization, have recognized limitations. We propose an alternative outcome, days alive and out of hospital (DAOH), which incorporates mortality and all hospitalizations into a single measure. A refinement, the patient journey, also uses functional status (New York Heart Association [NYHA] class) measured during follow-up. The CHARM program is used to illustrate the methodology. METHODS: CHARM randomized 7,599 patients with symptomatic HF to placebo or candesartan, with median follow-up of 38 months. We related DAOH and percent DAOH (ie, percentage of time spent alive and out of hospital) to treatment using linear regression adjusting for follow-up time. RESULTS: Mean increase in DAOH for patients on candesartan versus placebo was 24.1 days (95% CI 9.8-38.3 days, P < .001). The corresponding mean increase in percent DAOH was 2.0% (95% CI 0.8%-3.1%, P < .001). These findings were dominated by reduced mortality (23 days) but enhanced by reduced time in hospital (1 day). Percent time spent in hospital because of HF was reduced by 0.10% (95% CI 0.04%-0.14%, P < .001). The patient journey analysis showed that patients in the candesartan group spent more follow-up time in NYHA classes I and II and less in NYHA class IV. CONCLUSIONS: Days alive and out of hospital, especially percent DAOH, provide a valuable tool for summarizing the overall absolute treatment effect on mortality and morbidity. In future HF trials, percent DAOH can provide a useful alternative perspective on the effects of treatment.

- AimsWe examined the relationship between different degrees of QRS prolongation and different QRS morphologies and clinical outcomes in patients with heart failure, reduced ejection fraction (HF-REF), and mild symptoms in the Eplerenone in Mild Patients Hospitalization and SurvIval Study in Heart Failure trial (EMPHASIS-HF). We also evaluated the effect of eplerenone in these patients according to QRS duration/morphology. Methods and resultsPatients were categorized as: QRS duration (ms) (i) <120 (n = 1375); (ii) 120-149 (n = 517); and (iii) 150 (n = 383), and QRS morphology (i) normal (n = 1252); (ii) left bundle branch block (BBB) (n = 608); and (iii) right BBB/intraventricular conduction defect (IVCD) (n = 415). The outcomes examined were the composite of cardiovascular death or heart failure hospitalization and all-cause mortality. Both abnormal QRS duration and QRS morphology were associated with higher risk, e.g. the rates of the composite outcome were: 10.2, 17.6, and 15.5 per 100 patient-years in the <120, 120-149, and 150ms groups, respectively. Eplerenone reduced the risk of the primary outcome and mortality, compared with placebo, consistently across the QRS duration/morphology subgroups. ConclusionWe found that even moderate prolongation of QRS duration and right BBB/IVCD were associated with a high risk of adverse outcomes in HF-REF. Eplerenone was similarly effective, irrespective of QRS duration/morphology.

- AIMS: It is not known whether concomitant use of aspirin might attenuate the beneficial effects of mineralocorticoid receptor antagonists (MRAs). The purpose of this subgroup analysis was to explore the interaction between baseline aspirin treatment and the effect of eplerenone on the primary efficacy outcomes (composite of hospitalization for heart failure or cardiovascular mortality), its components, and safety markers [estimated glomerular filtration rate (eGFR), systolic blood pressure (SBP), and serum potassium >5.5 mmol/L] in the Eplerenone in Mild Patients Hospitalization and SurvIval Study in Heart Failure trial (EMPHASIS-HF). METHODS AND RESULTS: Patients with chronic heart failure, reduced ejection fraction (HFREF), and mild symptoms were enrolled in EMPHASIS-HF. We evaluated baseline characteristics according to aspirin use. We explored the interaction between aspirin and eplerenone, using Cox proportional hazards models providing adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) and P-values for interaction. Of the 2737 patients randomized, 1605 patients (58.6%) were taking aspirin. The beneficial effects of eplerenone on the primary endpoint were similar in patients not treated (adjusted HR 0.59, 95% CI 0.46-0.75) or treated (adjusted HR 0.71, 95% CI 0.59-0.87) with aspirin at baseline (interaction P-value = 0.19). We did not observe any significant modification of the safety markers by aspirin that was clinically meaningful. CONCLUSION: Aspirin use in patients with chronic systolic heart failure and mild symptoms did not substantially reduce the overall beneficial effects of the MRA eplerenone contrary to what has been described in some studies with ACE inhibitors.

- AIMS: Our objective was to create a simple prognostic risk score for patients with systolic heart failure and mild symptoms. We then assessed the efficacy of eplerenone across different categories of risk. METHODS AND RESULTS: The Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure trial (EMPHASIS-HF) was an international randomized trial, comparing eplerenone with placebo in 2737 patients with systolic heart failure and mild symptoms. The primary outcome was a composite of cardiovascular death or hospitalization for heart failure, over a median 2.1 years follow-up. Using multivariable Cox modelling age, sex, systolic blood pressure, estimated glomerular filtration rate, diabetes, BMI, haemoglobin, prior heart failure (HF) hospitalization, prior myocardial infarction/coronary artery bypass surgery (CABG), and heart rate were identified as strong independent risk factors. Estimates from the model were converted into a simple integer risk score which was categorized into three groups of low-, medium-, and high risk. In placebo patients, the rates (per 100 patient-years) for the primary outcome were 7.6, 19.0, and 39.4 in the low-, medium-, and high-risk groups, respectively. On eplerenone, these rates were reduced to 5.6, 12.2, and 24.2, respectively. Eplerenone was beneficial across all risk categories and the hazard ratios were similar. The absolute treatment benefit was greatest among those at highest risk. Similar patterns emerged for all-cause mortality and for all HF hospitalizations. CONCLUSION: This easy-to-use integer risk score should be of value in quantifying individual patient risk in patients with systolic HF and mild symptoms. The relative benefits of eplerenone appeared consistent across the whole spectrum of risk, including those at lower risk.

- Despite the availability of a number of different classes of therapeutic agents with proven efficacy in heart failure, the clinical course of heart failure patients is characterized by a reduction in life expectancy, a progressive decline in health-related quality of life and functional status, as well as a high risk of hospitalization. New approaches are needed to address the unmet medical needs of this patient population. The European Medicines Agency (EMA) is undertaking a revision of its Guideline on Clinical Investigation of Medicinal Products for the Treatment of Chronic Heart Failure. The draft version of the Guideline was released for public consultation in January 2016. The Cardiovascular Round Table of the European Society of Cardiology (ESC), in partnership with the Heart Failure Association of the ESC, convened a dedicated two-day workshop to discuss three main topic areas of major interest in the field and addressed in this draft EMA guideline: (i) assessment of efficacy (i.e. endpoint selection and statistical analysis); (ii) clinical trial design (i.e. issues pertaining to patient population, optimal medical therapy, run-in period); and (iii) research approaches for testing novel therapeutic principles (i.e. cell therapy). This paper summarizes the key outputs from the workshop, reviews areas of expert consensus, and identifies gaps that require further research or discussion. Collaboration between regulators, industry, clinical trialists, cardiologists, health technology assessment bodies, payers, and patient organizations is critical to address the ongoing challenge of heart failure and to ensure the development and market access of new therapeutics in a scientifically robust, practical and safe way.

- Objective: To perform a patient-pooled analysis of a routine invasive versus a selective invasive strategy in elderly patients with non-ST segment elevation acute coronary syndrome. Methods: A meta-analysis was performed of patientpooled data from the FRISC IIeICTUSeRITA-3 (FIR) studies. (Un)adjusted HRs were calculated by Cox regression, with adjustments for variables associated with age and outcomes. The main outcome was 5-year cardiovascular death or myocardial infarction (MI) following routine invasive versus selective invasive management. Results: Regarding the 5-year composite of cardiovascular death or MI, the routine invasive strategy was associated with a lower hazard in patients aged 65-74 years (HR 0.72, 95% CI 0.58 to 0.90) and those aged ≥75 years (HR 0.71, 95% CI 0.55 to 0.91), but not in those aged less than65 years (HR 1.11, 95% CI 0.90 to 1.38), p=0.001 for interaction between treatment strategy and age. The interaction was driven by an excess of early MIs in patients less than65 years of age; there was no heterogeneity between age groups concerning cardiovascular death. The benefits were smaller for women than for men (p=0.009 for interaction). After adjustment for other clinical risk factors the HRs remained similar. Conclusion: The current analysis of the FIR dataset shows that the long-term benefit of the routine invasive strategy over the selective invasive strategy is attenuated in younger patients aged less than65 years and in women by the increased risk of early events which seem to have no consequences for long-term cardiovascular mortality. No other clinical risk factors were able to identify patients with differential responses to a routine invasive strategy.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: We investigated the safety and efficacy of eplerenone in patients at high-risk for hyperkalemia or worsening renal function (WRF) in EMPHASIS-HF, a trial which enrolled patients aged at least 55 years with heart failure and reduced ejection fraction (HF-REF), in NYHA functional class II and with an eGFR>30ml/min/1.73m2 and serum potassium <5.0 mmol/l. Patients were receiving optimal therapy and most had been hospitalized for a cardiovascular reason within 180 days of inclusion. BACKGROUND: Underuse of eplerenone in patients with HF-REF may be due to fear of inducing hyperkalemia or WRF in high-risk patients. METHODS: This was a pre-specified analysis of subgroups of patients at high-risk of hyperkalemia or WRF (patients >/=75years, with diabetes, with eGFR<60ml/min/1.73m2, and with systolic blood pressure 5.5, >6.0 and <3.5mmol/l; hyperkalemia leading to study-drug discontinuation or hospitalization; and hospitalization for WRF) as well as the primary outcome (hospitalization for HF or cardiovascular mortality). RESULTS: In all high-risk subgroups, patients treated with eplerenone had an increased risk of potassium >5.5mmol/l but not of potassium >6.0mmol/l, and of hospitalization for hyperkalemia or discontinuation of study medication due to adverse events. Eplerenone was effective in reducing the primary composite endpoint in all sub-groups. CONCLUSIONS: In patients with chronic HF-REF, in NYHA class II and meeting specific inclusion and exclusion criteria, including an eGFR >30ml/min/1.73m2 and potassium <5.0 mmol/l, eplerenone was both efficacious and safe when carefully monitored, even in subgroups at high-risk of developing hyperkalemia or WRF.

- OBJECTIVES: The goal of this study was to identify potentially novel laboratory markers of risk in chronic heart failure patients. BACKGROUND: Although a variety of prognostic markers have been described in heart failure, a systematic assessment of routine laboratory values has not been reported. METHODS: All 2,679 symptomatic chronic heart failure patients from the North American CHARM (Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity) program had a wide range of laboratory measures performed at a core facility, enabling us to assess the relationship between routine blood tests and outcomes using a Cox proportional hazards model. We then replicated our findings in a cohort of 2,140 heart failure patients from the Duke Databank. RESULTS: Among 36 laboratory values considered in the CHARM program, higher red cell distribution width (RDW) showed the greatest association with morbidity and mortality (adjusted hazard ratio 1.17 per 1-SD increase, p < 0.001). Higher RDW was among the most powerful overall predictors, with only age and cardiomegaly showing a better independent association with outcome. This finding was replicated in the Duke Databank, in which higher RDW was strongly associated with all-cause mortality (adjusted hazard ratio 1.29 per 1 SD, p < 0.001), second only to age as a predictor of outcome. CONCLUSIONS: In 2 large contemporary heart failure populations, RDW was found to be a very strong independent predictor of morbidity and mortality. Understanding how and why this marker is associated with outcome may provide novel insights into heart failure pathophysiology.

- BACKGROUND: Patients with heart failure with reduced ejection fraction (HFrEF) and insulin-treated diabetes have a high risk of cardiovascular complications. Mineralocorticoid receptor antagonists may mitigate this risk. We aim to explore the effect of eplerenone on cardiovascular outcomes and all-cause mortality in HFrEF patients with diabetes, including those treated with insulin in the EMPHASIS-HF trial (Eplerenone in Patients with Systolic Heart Failure and Mild Symptoms). METHODS: The primary outcome was the composite of heart failure hospitalization or cardiovascular death. Cox models with treatment-by-diabetes subgroup interaction terms were used. RESULTS: The median follow-up was 21 (10-33) months. Of the 2737 patients included, 623 (23%) had non-insulin-treated diabetes, 236 (9%) had insulin-treated diabetes and 1878 did not have diabetes. Patients with insulin-treated diabetes were younger, more often women, with higher body mass index, waist circumference, more frequent ischemic heart failure cause, impaired kidney function, and longer diabetes duration. Compared with patients without diabetes, those with insulintreated diabetes had a 2-fold higher risk of having a primary outcome event. The hazard ratio (95% CI) for the effect of eplerenone, compared with placebo, on the primary outcome was 0.31 (0.19-0.50) in insulin-treated diabetes, 0.69 (0.500.93) in non-insulin-treated diabetes, and 0.72 (0.58-0.88) in patients without diabetes; interaction P=0.007. The annualized number needed-to-treat-to-benefit with regards to the primary outcome was 3 (95% CI, 3-4) in patients with insulin-treated diabetes, 16 (13-19) in patients with diabetes not receiving insulin, and 26 (24-28) in patients without diabetes. CONCLUSIONS: Patients with insulin-treated diabetes experienced a greater benefit from eplerenone than those with diabetes not treated with insulin and people without diabetes.

- Background Current heart failure guidelines recommend target eplerenone dose of 50 mg/day. We have examined the effect of different eplerenone doses based on pre-specified renal function stratification in the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF). Methods and results In EMPHASIS-HF, the target dose of eplerenone/placebo was stratified at randomization according to estimated glomerular filtration rate (eGFR): 50 mg/day if eGFR >= 50 mL/min/1.73m(2) and <= 25 mg/day if eGFR 30-49mL/min/1.73m(2). Patients remained within these dose ranges during the trial (as per stratification). The primary outcome was a composite of heart failure hospitalization or cardiovascular mortality. Eplerenone was superior to placebo within each respective eGFR stratum [eplerenone vs. placebo in the eGFR >= 50 mL/min/1.73m2 stratum: hazard ratio (HR) 0.58, 95% confidence interval (CI) 0.45-0.74; and eplerenone vs. placebo in the eGFR 30-49mL/min/1.73m(2) stratum: HR 0.62, 95% CI 0.49-0.78; P-interaction = 0.89]. Despite receiving lower eplerenone doses, patients in the eGFR 30-49mL/min/1.73m(2) stratum more often had hyperkalaemia, renal failure events, and drug discontinuation. Conclusion In EMPHASIS-HF the eplerenone dose was stratified according to renal function and the treatment effect was not influenced by renal function: 25 mg/day in patients with eGFR 30-49mL/min/1.73m(2) was as effective as 50 mg/day in patients with eGFR> = 50 mL/min/1.73m(2). However, patients with impaired renal function experienced more adverse events, despite reveiving lower eplerenone doses. Current guidelines do not recommend tailoring the dose of eplereone according to renal function but the current data suggest they should.
