- Aims Recurrent hospitalizations are a major part of the disease burden in heart failure (HF), but conventional analyses consider only the first event. We compared the effect of sacubitril/valsartan vs. enalapril on recurrent events, incorporating all HF hospitalizations and cardiovascular (CV) deaths in PARADIGM-HF, using a variety of statistical approaches advocated for this type of analysis.& para;& para;Methods and results In PARADIGM-HF, a total of 8399 patients were randomized and followed for a median of 27 months. We applied various recurrent event analyses, including a negative binomial model, the Wei, Lin and Weissfeld (WLW), and Lin, Wei, Ying and Yang (LWYY) methods, and a joint frailty model, all adjusted for treatment and region. Among a total of 3181 primary endpoint events (including 1251 CV deaths) during the trial, only 2031 (63.8%) were first events (836 CV deaths). Among a total of 1195 patients with at least one HF hospitalization, 410 (34%) had at least one further HF hospitalization. Sacubitril/valsartan compared with enalapril reduced the risk of recurrent HF hospitalization using the negative binomial model [rate ratio (RR) 0.77, 95% confidence interval (CI) 0.67-0.89], the WLW method [hazard ratio (HR) 0.79, 95% CI 0.71-0.89], the LWYY method (RR 0.78, 95% CI 0.68-0.90), and the joint frailty model (HR 0.75, 95% CI 0.66-0.86) (all P <0.001). The effect of sacubitril/valsartan vs. enalapril on recurrent HF hospitalizations/CV death was similar.& para;& para;Conclusions In PARADIGM-HF, approximately one third of patients with a primary endpoint (time-to-first) experienced a further event. Compared with enalapril, sacubitril/valsartan reduced both first and recurrent events. The treatment effect size was similar, regardless of the statistical approach applied.

- Background Angiotensin converting enzyme inhibitors (ACE-I), are beneficial both in heart failure with reduced ejection fraction (HF-REF) and after myocardial infarction (MI). We examined the effects of the angiotensin-receptor neprilysin inhibitor sacubitril/valsartan, compared with the ACE-I enalapril, on coronary outcomes in PARADIGM-HF. Methods and results We examined the effect of sacubitril/valsartan compared with enalapril on the following outcomes: i) the primary composite endpoint of cardiovascular (CV) death or HF hospitalization, ii) a pre-defined broader composite including, in addition, MI, stroke, and resuscitated sudden death, and iii) a post hoc coronary composite of CV-death, non-fatal MI, angina hospitalization or coronary revascularization. At baseline, of 8399 patients, 3634 (43.3%) had a prior MI and 4796 (57.1%) had a history of any coronary artery disease. Among all patients, compared with enalapril, sacubitril/valsartan reduced the risk of the primary outcome (HR 0.80 [0.73-0.87], P <.001), the broader composite (HR 0.83 [0.76-0.90], P <.001) and the coronary composite (HR 0.83 [0.75-0.92], P <.001). Although each of the components of the coronary composite occurred less frequently in the sacubitril/valsartan group, compared with the enalapril group, only CV death was reduced significantly. Conclusions Compared with enalapril, sacubitril/valsartan reduced the risk of both the primary endpoint and a coronary composite outcome in PARADIGM-HF. Additional studies on the effect of sacubitril/valsartan on atherothrombotic outcomes in high-risk patients are merited.

- AimEplerenone reduces the risk of cardiovascular death or first hospitalization for heart failure (HF) in patients with HF and a reduced ejection fraction (HFrEF), but it is still frequently underused in routine practice. We evaluated the time course of benefits of eplerenone after its initiation in HFrEF patients from the EMPHASIS-HF trial. Methods and resultsThe EMPHASIS-HF trial was a double-blind randomized clinical trial assessing the effect of eplerenone in patients (n = 2737, mean age 68.6 & PLUSMN; 7.6 years, 22.3% women) with HFrEF and mild symptoms. The time trajectories for the effect of eplerenone versus placebo on the primary composite endpoint (cardiovascular death or first hospitalization for HF) were investigated using Cox proportional hazards models with truncated data at each day post-randomization. A significant reduction in the primary composite endpoint was observed 26 days after randomization (hazard ratio 0.58; 95% confidence interval, 0.34-1.00, p = 0.049). Eplerenone was first associated with a significant reduction in the primary endpoint in 35 days or less in most subgroups, including patients with HF history & GE;18 months (day 24), estimated glomerular filtration rate <60 ml/min (day 12), ischaemic HF aetiology (day 28), age & GE;65 years (day 28), narrow QRS (day 30), higher MAGGIC score (day 35), lower potassium (day 30), left ventricular ejection fraction & GE;30% (day 28) or already treated with beta-blockers (day 25). ConclusionsEplerenone provides statistically significant and clinically meaningful benefits shortly after treatment initiation in most patients, irrespective of clinical profile. This result reinforces the need for an early initiation of eplerenone in HFrEF, as part of rapidly instituting guideline-directed medical therapy.

- Background-Many episodes of worsening of heart failure (HF) are treated by increasing oral therapy or temporary intravenous treatment in the community or emergency department (ED), without hospital admission. We studied the frequency and prognostic importance of these episodes of worsening in the Prospective Comparison of ARNI (angiotensin-receptor-neprilysin inhibitor) with ACEI (angiotensin-converting enzyme inhibitor) to Determine Impact on Global Mortality and Morbidity in Heart Failure Trial (PARADIGM-HF). Methods and Results-Outpatient intensification of HF therapy was added to an expanded composite outcome with ED visits, HF hospitalizations, and cardiovascular deaths. In an examination of first nonfatal events, 361 of 8399 patients (4.3%) had outpatient intensification of HF therapy without a subsequent event (ie, ED visit/HF hospitalizations) within 30 days; 78 of 8399 (1.0%) had an ED visit without previous outpatient intensification of HF therapy or a subsequent event within 30 days; and 1107 of 8399 (13.2%) had HF hospitalizations without a preceding event. The risk of death (in comparison with no-event patients) was similar after each manifestation of worsening: outpatient intensification of HF therapy (hazard ratio, 4.8; 95% confidence interval, 3.9-5.9); ED visit (hazard ratio, 4.5; 95% confidence interval, 3.0-6.7); HF hospitalizations (hazard ratio, 5.9; 95% confidence interval, 5.2-6.6). The expanded composite added 14% more events and shortened time to accrual of a fixed number of events. The benefit of sacubitril/valsartan over enalapril was similar to the primary outcome for the expanded composite (hazard ratio, 0.79; 95% confidence interval, 0.73-0.86) and was consistent across the components of the latter. Conclusions-Focusing only on HF hospitalizations underestimates the frequency of worsening and the serious implications of all manifestations of worsening. For clinical trials conducted in an era of heightened efforts to avoid HF hospitalizations, inclusion of episodes of outpatient treatment intensification (and ED visits) in a composite outcome adds an important number of events and shortens the time taken to accrue a target number of end points in an event-driven trial.

- AIMS: To evaluate the effect of the angiotensin receptor blocker candesartan on patients' perception of symptoms, using the McMaster Overall treatment evaluation (OTE), in a broad spectrum of patients with chronic heart failure (CHF). METHODS AND RESULTS: Patients with symptomatic CHF, randomised in the CHARM Programme in North America (n=2498), were studied. OTE was assessed at baseline, at 6, 14 and 26 months and the patient's final or closing visit. Patient's status was classified as "improved (score +1 to +7)", "unchanged (score 0)" or "deteriorated (score -1 to -7)" at the end of the study compared to baseline. Both a simple "last visit carried forward" (LVCF) analysis and "worst rank carried forward" (WRCF) analysis (where patients who died were allocated the worst OTE score) were used. In the LVCF analysis, compared to placebo, more candesartan patients improved (37.7% versus 33.5%) and fewer worsened (10.8% versus 12.0%) in OTE (p=0.017). The WRCF analysis also showed better overall OTE scores with candesartan compared to placebo (p=0.029). There was no heterogeneity in the response to candesartan between the CHARM component trials or across four exploratory sub-groups (age, sex, NYHA class and beta-blocker). CONCLUSIONS: Candesartan was shown to be better than placebo, when using the McMaster OTE to measure patient perception of treatment. More patients treated with candesartan reported improvement and fewer reported deterioration. This benefit was obtained when candesartan was added to extensive background therapy and is consistent with the benefits of candesartan on NYHA class, hospital admission for worsening heart failure and mortality.

- AIMS: The curiosity that leanness is associated with poor survival in patients with chronic heart failure (CHF) needs further insight by investigating the impact of weight loss on prognosis in a large sample of patients across a broad spectrum of both reduced and preserved left ventricular (LV) systolic function. METHODS AND RESULTS: We investigated the change in weight over 6 months in 6933 patients in the Candesartan in Heart failure: Reduction in Mortality and morbidity (CHARM) programme, and its association with subsequent mortality (1435 deaths) over a median 32.9 months follow-up using Cox proportional hazard models to account for the impact of body mass index and other risk predictors. We then used time-updated Cox models to relate each patient's ongoing data on annual weight change to their mortality hazard. The percentage weight loss over 6 months had a highly significant monotonically increasing association with excess mortality, both for cardiovascular and for other causes of death. Patients with 5% or greater weight loss in 6 months had over a 50% increase in hazard compared with those with stable weight. Weight loss carried a particularly high risk in patients who were already lean at study entry. Findings were similar in the presence of dependent oedema, preserved or reduced LV ejection fraction, and treatment with candesartan, although weight loss was significantly less common on candesartan. The time-updated analyses revealed an even stronger link between weight loss and short-term risk of dying, i.e. risk increased more than four-fold for patients whose last recorded annual weight loss exceeded 10%. Weight gain had a more modestly increased short-term mortality risk. Weight loss accelerates in the year prior to death. CONCLUSIONS: Weight loss and leanness are important predictors of poor prognosis in CHF. Being lean and losing weight is particularly bad. The detection of weight change, and particularly weight loss, should be considered as an adverse sign prompting further evaluation.

- No studies have examined the effect of mineralocorticoid receptor antagonist therapy on new-onset diabetes. In addition, though the combination of diabetes and chronic heart failure (CHF) carries a poor prognosis, few studies have examined predictors of new-onset diabetes in those with CHF. In patients with symptomatically mild CHF who participated in the placebo-controlled Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure, we examined the effect of the aldosterone antagonist, eplerenone, on physician-diagnosed diabetes using univariate Cox proportional hazard analysis. To identify predictors of new-onset diabetes (measures of glycaemia were not available), data from trial arms were combined and multivariate Cox proportional hazard analyses and receiver operating characteristic curve analyses were conducted. At baseline, the mean age of 1846 initially non-diabetic patients was 69 years and mean left ventricular ejection fraction was 26. Over 21 months, 69 (3.7) developed diabetes (33 on eplerenone, 36 on placebo). Eplerenone had no effect on new-onset diabetes [hazard ratio (HR) 0.94, 95 confidence interval (CI) 0.591.52] and no effect on the composite of new-onset diabetes or mortality (HR 0.80, 95 CI 0.641.01). Independent predictors of new-onset diabetes included digoxin therapy, higher serum alanine aminotransferase, longer duration of heart failure, current or previous smoker, higher waist circumference, lower age, and higher systolic blood pressure with a combined c-statistic of 0.74. Eplerenone had no effect on new-onset diabetes in patients with CHF, but further large-scale studies are required to address this question comprehensively. Commonly recorded parameters provided useful information for predicting new-onset diabetes.

- Aims Heart failure is characterized by recurrent hospitalizations, but often only the first event is considered in clinical trial reports. In chronic diseases, such as heart failure, analysing all events gives a more complete picture of treatment benefit. We describe methods of analysing repeat hospitalizations, and illustrate their value in one major trial. Methods and results The Candesartan in Heart failure Assessment of Reduction in Mortality and morbidity (CHARM)-Preserved study compared candesartan with placebo in 3023 patients with heart failure and preserved systolic function. The heart failure hospitalization rates were 12.5 and 8.9 per 100 patient-years in the placebo and candesartan groups, respectively. The repeat hospitalizations were analysed using the Andersen-Gill, Poisson, and negative binomial methods. Death was incorporated into analyses by treating it as an additional event. The win ratio method and a method that jointly models hospitalizations and mortality were also considered. Using repeat events gave larger treatment benefits than time to first event analysis. The negative binomial method for the composite of recurrent heart failure hospitalizations and cardiovascular death gave a rate ratio of 0.75 [95% confidence interval (CI) 0.62-0.91, P = 0.003], whereas the hazard ratio for time to first heart failure hospitalization or cardiovascular death was 0.86 (95% CI 0.74-1.00, P = 0.050). Conclusions In patients with preserved EF, candesartan reduces the rate of admissions for worsening heart failure, to a greater extent than apparent from analysing only first hospitalizations. Recurrent events should be routinely incorporated into the analysis of future clinical trials in heart failure.

Ingår i: New England Journal of Medicine. - 0028-4793. ; 377:1, s. 41-51

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND The risk of sudden death has changed over time among patients with symptomatic heart failure and reduced ejection fraction with the sequential introduction of medications including angiotensin-converting-enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, and mineralocorticoid-receptor antagonists. We sought to examine this trend in detail. We analyzed data from 40,195 patients who had heart failure with reduced ejection fraction and were enrolled in any of 12 clinical trials spanning the period from 1995 through 2014. Patients who had an implantable cardioverter-defibrillator at the time of trial enrollment were excluded. Weighted multivariable regression was used to examine trends in rates of sudden death over time. Adjusted hazard ratios for sudden death in each trial group were calculated with the use of Cox regression models. The cumulative incidence rates of sudden death were assessed at different time points after randomization and according to the length of time between the diagnosis of heart failure and randomization. Sudden death was reported in 3583 patients. Such patients were older and were more often male, with an ischemic cause of heart failure and worse cardiac function, than those in whom sudden death did not occur. There was a 44% decline in the rate of sudden death across the trials (P = 0.03). The cumulative incidence of sudden death at 90 days after randomization was 2.4% in the earliest trial and 1.0% in the most recent trial. The rate of sudden death was not higher among patients with a recent diagnosis of heart failure than among those with a longer-standing diagnosis. Rates of sudden death declined substantially over time among ambulatory patients with heart failure with reduced ejection fraction who were enrolled in clinical trials, a finding that is consistent with a cumulative benefit of evidence-based medications on this cause of death.

- Background Sudden death (SD) and pump failure death (PFD) are the two leading causes of death in patients with heart failure and reduced ejection fraction (HFrEF). Objective Identifying patients at higher risk for mode-specific death would allow better targeting of individual patients for relevant device and other therapies. Methods We developed models in 7156 patients with HFrEF from the Prospective comparison of ARNI with ACEI to Determine Impact on Global Mortality and morbidity in Heart Failure (PARADIGM-HF) trial, using Fine-Gray regressions counting other deaths as competing risks. The derived models were externally validated in the Aliskiren Trial to Minimize Outcomes in Patients with Heart Failure (ATMOSPHERE) trial. Results NYHA class and NT-proBNP were independent predictors for both modes of death. The SD model additionally included male sex, Asian or Black race, prior CABG or PCI, cancer history, MI history, treatment with LCZ696 vs. enalapril, QRS duration and ECG left ventricular hypertrophy. While LVEF, ischemic etiology, systolic blood pressure, HF duration, ECG bundle branch block, and serum albumin, chloride and creatinine were included in the PFD model. Model discrimination was good for SD and excellent for PFD with Harrell's C of 0.67 and 0.78 after correction for optimism, respectively. The observed and predicted incidences were similar in each quartile of risk scores at 3 years in each model. The performance of both models remained robust in ATMOSPHERE. Conclusion We developed and validated models which separately predict SD and PFD in patients with HFrEF. These models may help clinicians and patients consider therapies targeted at these modes of death.
