- BACKGROUND In patients with type 2 diabetes, inhibitors of sodium-glucose cotransporter 2 (SGLT2) reduce the risk of a first hospitalization for heart failure, possibly through glucose-independent mechanisms. More data are needed regarding the effects of SGLT2 inhibitors in patients with established heart failure and a reduced ejection fraction, regardless of the presence or absence of type 2 diabetes.METHODS In this phase 3, placebo-controlled trial, we randomly assigned 4744 patients with New York Heart Association class II, III, or IV heart failure and an ejection fraction of 40% or less to receive either dapagliflozin (at a dose of 10 mg once daily) or placebo, in addition to recommended therapy. The primary outcome was a composite of worsening heart failure (hospitalization or an urgent visit resulting in intravenous therapy for heart failure) or cardiovascular death.RESULTS Over a median of 18.2 months, the primary outcome occurred in 386 of 2373 patients (16.3%) in the dapagliflozin group and in 502 of 2371 patients (21.2%) in the placebo group (hazard ratio, 0.74; 95% confidence interval [CI], 0.65 to 0.85; P<0.001). A first worsening heart failure event occurred in 237 patients (10.0%) in the dapagliflozin group and in 326 patients (13.7%) in the placebo group (hazard ratio, 0.70; 95% CI, 0.59 to 0.83). Death from cardiovascular causes occurred in 227 patients (9.6%) in the dapagliflozin group and in 273 patients (11.5%) in the placebo group (hazard ratio, 0.82; 95% CI, 0.69 to 0.98); 276 patients (11.6%) and 329 patients (13.9%), respectively, died from any cause (hazard ratio, 0.83; 95% CI, 0.71 to 0.97). Findings in patients with diabetes were similar to those in patients without diabetes. The frequency of adverse events related to volume depletion, renal dysfunction, and hypoglycemia did not differ between treatment groups.CONCLUSIONS Among patients with heart failure and a reduced ejection fraction, the risk of worsening heart failure or death from cardiovascular causes was lower among those who received dapagliflozin than among those who received placebo, regardless of the presence or absence of diabetes.

- AIMS: It is unknown whether there is an interaction between aspirin and angiotensin receptor blockers on outcomes in patients with heart failure (HF). METHODS AND RESULTS: The efficacy and safety of candesartan vs. placebo was assessed in 7599 patients with symptomatic HF and reduced or preserved left ventricular ejection fraction enrolled in the CHARM programme according to baseline aspirin use. Patients were randomized to candesartan or matching placebo and were followed for a median of 38 months. Aspirin was used in 4246 (55.9%) of patients at baseline. When compared with placebo, candesartan use was associated with lower event rates for cardiovascular (CV) death or HF hospitalization (primary outcome) in both the aspirin group (28 vs. 31.9%, HR 0.81, 95% CI 0.72-0.90) and non-aspirin group (33 vs. 38%, HR 0.81, 95% CI 0.72-0.91). Baseline aspirin use did not modify the effectiveness of candesartan in reducing the risk of CV death or HF hospitalization in CHARM overall (P = 0.64) or in the CHARM individual trials. In addition, there was no significant interaction between aspirin therapy and candesartan in terms of discontinuation of study drug due to adverse reactions (P = 0.72). CONCLUSION: There appears to be no significant modification of the benefit of candesartan on CV mortality and morbidity outcomes or safety by concomitant use of aspirin in patients with chronic HF.

- OBJECTIVES The authors investigated the relationship between past or incident myocardial infarction (MI) and car-diovascular (CV) events in heart failure with preserved ejection fraction (HFpEF). BACKGROUND MI and HFpEF share some common risk factors. The prognostic significance of MI in patients with HFpEF is uncertain. METHODS The authors pooled data from 3 trials-CHARM Preserved (Candesartan Cilexietil in Heart Failure Assessment of Reduction in Mortality and Morbidity), I-Preserve (Irbesartan in Heart Failure With Preserved Systolic Function), and the Americas region of TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) (N 1/4 8,916)-and examined whether MI before or following enrollment independently predicted CV death and heart failure (HF) hospitalization. RESULTS At baseline, 2,668 patients (30%) had history of MI. Prior MI was independently associated with greater risk of CV death (4.7 vs. 3.5 events/100 patient-years [py], adjusted hazard ratio [HR]: 1.42 [95% confidence interval (CI): 1.23 to 1.64]; p < 0.001). Excess sudden death drove this difference (1.9 vs. 1.2 events/100 py, adjusted HR: 1.55 [95% CI: 1.23 to 1.97]; p < 0.001). There was no difference in HF hospitalization (5.9 vs. 5.5 events/100 py, adjusted HR: 1.05, 95% CI: 0.92 to 1.19) or HF death by prior MI. During follow-up, MI occurred in 336 patients (3.8%). Risk of CV death increased 31-fold in the first 30 days after first post-enrollment MI, and remained 58% higher beyond 1 year after MI. Risk of first or recurrent HF hospitalization increased 2.4-fold after MI. CONCLUSIONS Prior MI in HFpEF is associated with greater CV and sudden death but similar risk of HF outcomes. Patients with HFpEF who experience MI are at high risk of subsequent CV death and HF hospitalization. These data highlight the importance of primary and secondary prevention of MI in patients with HFpEF.

- OBJECTIVES: We explored the incidence and predictors of hyperkalemia in a broad population of heart failure patients. BACKGROUND: When used in optimal doses to treat patients with heart failure, renin-angiotensin-aldosterone system (RAAS) inhibitors improve clinical outcomes but can cause hyperkalemia. METHODS: Participants in the CHARM (Candesartan in Heart Failure-Assessment of Reduction in Mortality and Morbidity) (n = 7,599) Program were randomized to standard heart failure therapy plus candesartan or placebo, titrated as tolerated to a target of 32 mg once daily with recommended monitoring of serum potassium and creatinine. We assessed the incidence and predictors of hyperkalemia associated with dose reduction, study drug discontinuation, hospitalization, or death over the median 3.2 years of follow-up. RESULTS: Independent of treatment assignment, the risk of hyperkalemia increased with age > or =75 years, male gender, diabetes, creatinine > or =2.0 mg/dl, K+ > or =5.0 mmol/l, and background use of angiotensin-converting enzyme inhibitors or spironolactone. Candesartan increased the rate of aggregate hyperkalemia from 1.8% to 5.2% (difference 3.4%, p < 0.0001) and serious hyperkalemia (associated with death or hospitalization) from 1.1% to 1.8% (difference 0.7%, p < 0.001), with hyperkalemia associated with death reported in 2 (0.05%) candesartan patients and 1 (0.03%) placebo patient. The benefit of candesartan in reducing cardiovascular death or heart failure hospitalization (relative risk reduction 16%, p < 0.0001) was uniform in these subgroups, as was the incremental risk of hyperkalemia. CONCLUSIONS: The risk of hyperkalemia is increased in symptomatic heart failure patients with advanced age, male gender, baseline hyperkalemia, renal failure, diabetes, or combined RAAS blockade. Although these groups derive incremental clinical benefit from candesartan, careful surveillance of serum potassium and creatinine is particularly important.

- OBJECTIVE The sodium–glucose cotransporter 2 inhibitor dapagliflozin reduced the risk of cardiovascular mortality and worsening heart failure in the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) trial. This report explores the effect of dapagliflozin on incident type 2 diabetes (T2D) in the cohort without diabetes enrolled in the trial. RESEARCH DESIGN AND METHODS The subgroup of 2,605 patients with heart failure and reduced ejection fraction (HFrEF), no prior history of diabetes, and an HbA1c of <6.5% at baseline was randomized to dapagliflozin 10 mg daily or placebo. In this exploratory analysis, surveillance for new-onset diabetes was accomplished through periodic HbA1c testing as part of the study protocol and comparison between the treatment groups assessed through a Cox proportional hazards model. RESULTS At baseline, the mean HbA1c was 5.8%. At 8 months, there were minimal changes, withaplacebo-adjusted change inthedapagliflozin groupof20.04%. Over a median follow-up of 18 months, diabetes developed in 93 of 1,307 patients (7.1%) in the placebogroup and 64 of 1,298 (4.9%) in the dapagliflozingroup. Dapagliflozin led to a 32% reduction in diabetes incidence (hazard ratio 0.68, 95% CI 0.50–0.94; P 5 0.019). More than 95% of the participants who developed T2D had prediabetes at baseline (HbA1c 5.7–6.4%). Participants who developed diabetes in DAPA-HF had a higher subsequent mortality than those who did not. CONCLUSIONS In this exploratory analysis among patients with HFrEF, treatment with dapagliflozin reduced the incidence of new diabetes. This potential benefit needs confirmation in trials of longer duration and in people without heart failure. © 2020 by the American Diabetes Association.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Increased excretion of albumin in urine might be a marker of the various pathophysiological changes that arise in patients with heart failure. Therefore our aim was to assess the prevalence and prognostic value of a spot urinary albumin to creatinine ratio (UACR) in patients with heart failure. METHODS: UACR was measured at baseline and during follow-up of 2310 patients in the Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) Programme. The prevalence of microalbuminuria and macroalbuminuria, and the predictive value of UACR for the primary composite outcome of each CHARM study--ie, death from cardiovascular causes or admission to hospital with worsening heart failure--and death from any cause were assessed. FINDINGS: 1349 (58%) patients had a normal UACR, 704 (30%) had microalbuminuria, and 257 (11%) had macroalbuminuria. The prevalence of increased UACR was similar in patients with reduced and preserved left ventricular ejection fractions. Patients with an increased UACR were older, had more cardiovascular comorbidity, worse renal function, and a higher prevalence of diabetes mellitus than did those with normoalbuminuria. However, a high prevalence of increased UACR was still noted among patients without diabetes, hypertension, or renal dysfunction. Elevated UACR was associated with increased risk of the composite outcome and death even after adjustment for other prognostic variables including renal function, diabetes, and haemoglobin A1c. The adjusted hazard ratio (HR) for the composite outcome in patients with microalbuminuria versus normoalbuminuria was 1.43 (95% CI 1.21-1.69; p<0.0001) and for macroalbuminuria versus normoalbuminuria was 1.75 (1.39-2.20; p<0.0001). The adjusted values for death were 1.62 (1.32-1.99; p<0.0001) for microalbuminuria versus normoalbuminuria, and 1.76 (1.32-2.35; p=0.0001) for macroalbuminuria versus normoalbuminuria. Treatment with candesartan did not reduce or prevent the development of excessive excretion of urinary albumin. INTERPRETATION: Increased UACR is a powerful and independent predictor of prognosis in heart failure. FUNDING: AstraZeneca.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: We wished to determine the prevalence of, potential mechanistic associations of, and clinical outcomes related to anemia in patients with heart failure and a broad spectrum of left ventricular ejection fraction (LVEF). METHODS AND RESULTS: In multivariable analyses, we examined the associations between hemoglobin and baseline characteristics, laboratory variables, and outcomes in 2653 patients randomized in the CHARM Program in the United States and Canada. Anemia was equally common in patients with preserved (27%) and reduced (25%) LVEF but was more common in black and older patients. Anemia was associated with ethnicity, diabetes, low body mass index, higher systolic and lower diastolic blood pressure, and recent heart failure hospitalization. More than 50% of anemic patients had a glomerular filtration rate <60 mL.min(-1).1.73 m(-2) compared with <30% of nonanemic patients. Despite an inverse relationship between hemoglobin and LVEF, anemia was associated with an increased risk of death and hospitalization, a relationship observed in patients with both reduced and preserved LVEF. There were 133 versus 69 deaths and 527 versus 352 hospitalizations per 1000 patient-years of follow-up in anemic versus nonanemic patients (both P<0.001). The effect of candesartan in reducing outcomes was independent of hemoglobin. CONCLUSIONS: Anemia was common in heart failure, regardless of LVEF. Lower hemoglobin was associated with higher LVEF yet was an independent predictor of adverse mortality and morbidity outcomes. In heart failure, the causes of anemia and the associations between anemia and outcomes are probably multiple and complex.

- BACKGROUND: We wished to test previous hypotheses that sex-related differences in mortality and morbidity may be due to differences in the cause of heart failure or in left ventricular ejection fraction (LVEF) by comparing fatal and nonfatal outcomes in women and men with heart failure and a broad spectrum of left ventricular ejection fraction. METHODS AND RESULTS: We compared outcomes in 2400 women and 5199 men randomized in the Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) program using multivariable regression analyses. A total of 1188 women (50%) had a low LVEF (< or = 0.40), and 1212 had a preserved LVEF (> 0.40). Among the men, 3388 (65%) had a low LVEF, and 1811 had a preserved LVEF. A total of 1216 women (51%) and 3465 men (67%) had an ischemic cause of their heart failure. All-cause mortality was 21.5% in women and 25.3% in men (adjusted hazard ratio [HR], 0.77; 95% CI, 0.69 to 0.86; P<0.001). Fewer women (30.4%) than men (33.3%) experienced cardiovascular death or heart failure hospitalization (adjusted HR, 0.83; 95% CI, 0.76 to 0.91; P<0.001). The risks of sudden death (HR, 0.70; 95% CI, 0.58 to 0.85) and death due to worsening heart failure (HR, 0.72; 95% CI, 0.58 to 0.89) were reduced to a comparable extent. The adjusted risk of cardiovascular hospitalization was also lower in women (HR, 0.88; 95% CI, 0.82 to 0.95), mainly because of a reduced risk of heart failure hospitalization (HR, 0.87; 95% CI, 0.78 to 0.97). Women had a lower risk of death irrespective of cause of heart failure or LVEF. CONCLUSIONS: Among patients with heart failure, women have lower risks of most fatal and nonfatal outcomes that are not explained, as previously suggested, by LVEF or origin of the heart failure.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: -Clinical trials in heart failure have focused on the improvement in symptoms or decreases in the risk of death and other cardiovascular events. Little is known about the effect of drugs on the risk of clinical deterioration in surviving patients. METHODS AND RESULTS: -We compared the angiotensin-neprilysin inhibitor LCZ696 (400 mg daily) with the angiotensinconverting enzyme inhibitor enalapril (20 mg daily) in 8399 patients with heart failure and reduced ejection fraction in a double-blind trial. The analyses focused on prespecified measures of nonfatal clinical deterioration. In comparison with the enalapril group, fewer LCZ696-treated patients required intensification of medical treatment for heart failure (520 versus 604; hazard ratio, 0.84; 95% confidence interval, 0.74-0.94; P=0.003) or an emergency department visit for worsening heart failure (hazard ratio, 0.66; 95% confidence interval, 0.52-0.85; P=0.001). The patients in the LCZ696 group had 23% fewer hospitalizations for worsening heart failure (851 versus 1079; P<0.001) and were less likely to require intensive care (768 versus 879; 18% rate reduction, P=0.005), to receive intravenous positive inotropic agents (31% risk reduction, P<0.001), and to have implantation of a heart failure device or cardiac transplantation (22% risk reduction, P=0.07). The reduction in heart failure hospitalization with LCZ696 was evident within the first 30 days after randomization. Worsening of symptom scores in surviving patients was consistently more common in the enalapril group. LCZ696 led to an early and sustained reduction in biomarkers of myocardial wall stress and injury (N-terminal pro-Btype natriuretic peptide and troponin) versus enalapril. CONCLUSIONS: -Angiotensin-neprilysin inhibition prevents the clinical progression of surviving patients with heart failure more effectively than angiotensin-converting enzyme inhibition.

- Background: The net clinical benefit of cardiac disease-modifying drugs might be influenced by the interaction of different domains of disease burden. We assessed the relative contribution of cardiac, comorbid, and demographic factors in heart failure (HF) and how their interplay might influence HF prognosis and efficacy of sacubitril/valsartan across the spectrum of left ventricular ejection fraction. Methods: We combined data from 2 global trials that evaluated the efficacy of sacubitril/valsartan compared with a renin-angiotensin antagonist in symptomatic HF patients (PARADIGM-HF [Prospective Comparison of Angiotensin Receptor Neprilysin Inhibitor With an Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure; n=8399] and PARAGON-HF [Prospective Comparison of Angiotensin-Converting Enzyme Inhibitor With Angiotensin Receptors Blockers Global Outcomes in Heart Failure With Preserved Ejection Fraction; n=4796]). We decomposed the previously validated Meta-Analysis Global Group in Chronic Heart Failure risk score into cardiac (left ventricular ejection fraction, New York Heart Association class, blood pressure, time since HF diagnosis, HF medications), noncardiac comorbid (body mass index, creatinine, diabetes, chronic obstructive pulmonary disease, smoking), and demographic (age, gender) categories. Based on these domains, an index representing the balance of cardiac to noncardiac comorbid burden was created (cardiac-comorbid index). Clinical outcomes were time to first HF hospitalization or cardiovascular deaths and all-cause mortality. Results: Higher scores of the cardiac domain were observed in PARADIGM-HF (10 [7-13] versus 5 [3-6], P<0.001) and higher scores of the demographic domain in PARAGON-HF (10 [8-13] versus 5 [2-9], P<0.001). In PARADIGM-HF, the contribution of the cardiac domain to clinical outcomes was greater than the noncardiac domain (P<0.001), while in PARAGON-HF the attributable risk of the comorbid and demographic categories predominated. Individual scores from each sub-domain were linearly associated with the risk of clinical outcomes (P<0.001). Beneficial effects of sacubitril/valsartan were observed in patients with preponderance of cardiac over noncardiac comorbid burden (cardiac-comorbid index >5 points), suggesting a significant treatment effect modification (interaction P<0.05 for both outcomes). Conclusions: Domains of disease burden are clinically relevant features that influence the prognosis and treatment of patients with HF. The therapeutic benefits of sacubitril/valsartan vary according to the balance of components of disease burden, across different ranges of left ventricular ejection fraction.
