- AIMS: In heart failure with reduced ejection fraction (HFrEF), there is an ’obesity paradox’, where survival is better in patients with a higher body mass index (BMI) and weight loss is associated with worse outcomes. We examined the effect of a sodium-glucose co-transporter 2 inhibitor according to baseline BMI in the Dapagliflozin And Prevention of Adverse- outcomes in Heart Failure trial (DAPA-HF). METHODS AND RESULTS: Body mass index was examined using standard categories, i.e. underweight ($<$18.5 kg/m(2) ); normal weight (18.5-24.9 kg/m(2) ); overweight (25.0-29.9 kg/m(2) ); obesity class I (30.0-34.9 kg/m(2) ); obesity class II (35.0-39.9 kg/m(2) ); and obesity class III ($>$/=40 kg/m(2) ). The primary outcome in DAPA-HF was the composite of worsening heart failure or cardiovascular death. Overall, 1348 patients (28.4%) were under/normal- weight, 1722 (36.3%) overweight, 1013 (21.4%) obesity class I and 659 (13.9%) obesity class II/III. The unadjusted hazard ratio (95% confidence interval) for the primary outcome with obesity class 1, the lowest risk group, as reference was: under/normal-weight 1.41 (1.16-1.71), overweight 1.18 (0.97-1.42), obesity class II/III 1.37 (1.10-1.72). Patients with class I obesity were also at lowest risk of death. The effect of dapagliflozin on the primary outcome and other outcomes did not vary by baseline BMI, e.g. hazard ratio for primary outcome: under/normal-weight 0.74 (0.58-0.94), overweight 0.81 (0.65-1.02), obesity class I 0.68 (0.50-0.92), obesity class II/III 0.71 (0.51-1.00) (P-value for interaction = 0.79). The mean decrease in weight at 8 months with dapagliflozin was 0.9 (0.7-1.1) kg (P $<$ 0.001). CONCLUSION: We confirmed an ’obesity survival paradox’ in HFrEF. We showed that dapagliflozin was beneficial across the wide range of BMI studied. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT03036124.

- BACKGROUND: Effective therapies for HFrEF usually reduce NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels, and it is important to establish whether new treatments are effective across the range of NT- proBNP. METHODS: We evaluated both these questions in the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) trial. Patients in New York Heart Association functional class II to IV with a left ventricular ejection fraction $<$/=40% and a NT-proBNP level $>$/=600 pg/mL ($>$/=600 ng/L; $>$/=400 pg/mL if hospitalized for HF within the previous 12 months or $>$/=900 pg/mL if atrial fibrillation/flutter) were eligible. The primary outcome was the composite of an episode of worsening HF or cardiovascular death. RESULTS: Of the 4744 randomized patients, 4742 had an available baseline NT-proBNP measurement (median, 1437 pg/mL [interquartile range, 857-2650 pg/mL]). Compared with placebo, treatment with dapagliflozin significantly reduced NT-proBNP from baseline to 8 months (absolute least-squares mean reduction, -303 pg/mL [95% CI, -457 to -150 pg/mL]; geometric mean ratio, 0.92 [95% CI, 0.88-0.96]). Dapagliflozin reduced the risk of worsening HF or cardiovascular death, irrespective of baseline NT-proBNP quartile; the hazard ratio for dapagliflozin versus placebo, from lowest to highest quartile was 0.43 (95% CI, 0.27-0.67), 0.77 (0.56-1.04), 0.78 (0.60-1.01), and 0.78 (0.64-0.95); P for interaction=0.09. Consistent benefits were observed for all-cause mortality. Compared with placebo, dapagliflozin increased the proportion of patients with a meaningful improvement ($>$/=5 points) in Kansas City Cardiomyopathy Questionnaire total symptom score (P for interaction=0.99) and decreased the proportion with a deterioration $>$/=5 points (P for interaction=0.87) across baseline NT-proBNP quartiles. CONCLUSIONS: In patients with HFrEF, dapagliflozin reduced NT-proBNP by 300 pg/mL after 8 months of treatment compared with placebo. In addition, dapagliflozin reduced the risk of worsening HF and death, and improved symptoms, across the spectrum of baseline NT-proBNP levels included in DAPA-HF.

- Importance: Women may respond differently to certain treatments for heart failure (HF) with reduced ejection fraction (HFrEF) than men. Objective: To investigate the efficacy and safety of dapagliflozin compared with placebo in men and women with HFrEF enrolled in the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure trial (DAPA-HF). Design, Setting, and Participants: Prespecified subgroup analysis of a phase 3 randomized clinical trial conducted at 410 sites in 20 countries. Patients with New York Heart Association functional class II through IV with an ejection fraction of 40% or less and elevated N-terminal pro-B- type natriuretic peptide were eligible. Data were analyzed between June 2020 and January 2021. Interventions: Addition of once-daily 10 mg of dapagliflozin or placebo to guideline-recommended therapy. Main Outcomes and Measures: The primary outcome was the composite of an episode of worsening HF (HF hospitalization or urgent HF visit requiring intravenous therapy) or cardiovascular death. Results: A total of 4744 patients were randomized in DAPA-HF, of whom 1109 were women (23.4%). Compared with placebo, dapagliflozin reduced the risk of worsening HF events or cardiovascular death to a similar extent in both men and women (hazard ratios, 0.73 [95% CI, 0.63-0.85] and 0.79 [95% CI, 0.59-1.06], respectively; P for interaction = .67). Consistent benefits were observed for the components of the primary outcome and all-cause mortality. Compared with placebo, dapagliflozin increased the proportion of patients with a meaningful improvement in symptoms (Kansas City Cardiomyopathy Questionnaire total symptom score of $>$/=5 points; men, 59% vs 50%; women, 57% vs 54%; P for interaction = .14) and decreased the proportion with worsening symptoms (Kansas City Cardiomyopathy Questionnaire total symptom score decrease of $>$/=5 points; men, 25% vs 34%; women, 27% vs 31%; P for interaction = .15), irrespective of sex. Results were consistent for the Kansas City Cardiomyopathy Questionnaire clinical summary score and overall summary score. Study drug discontinuation and serious adverse events were not more frequent in the dapagliflozin group than in the placebo group in either men or women. Conclusions and Relevance: Dapagliflozin reduced the risk of worsening HF, cardiovascular death, and all-cause death and improved symptoms, physical function, and health-related quality of life similarly in men and women with heart failure and reduced ejection fraction. In addition, dapagliflozin was safe and well-tolerated irrespective of sex. Trial Registration: ClinicalTrials.gov Identifier: NCT03036124.

- AIMS: Chronic obstructive pulmonary disease (COPD) is an important comorbidity in heart failure (HF) with reduced ejection fraction (HFrEF), associated with worse outcomes and often suboptimal treatment because of under-prescription of beta-blockers. Consequently, additional effective therapies are especially relevant in patients with COPD. The aim of this study was to examine outcomes related to COPD in a post hoc analysis of the Dapagliflozin And Prevention of Adverse-outcomes in Heart Failure (DAPA-HF) trial. METHODS AND RESULTS: We examined whether the effects of dapagliflozin in DAPA-HF were modified by COPD status. The primary outcome was the composite of an episode of worsening HF or cardiovascular death. Overall, 585 (12.3%) of the 4744 patients randomized had a history of COPD. Patients with COPD were more likely to be older men with a history of smoking, worse renal function, and higher baseline N-terminal pro B-type natriuretic peptide, and less likely to be treated with a beta-blocker or mineralocorticoid receptor antagonist. The incidence of the primary outcome was higher in patients with COPD than in those without [18.9 (95% confidence interval 16.0-22.2) vs. 13.0 (12.1-14.0) per 100 person-years; hazard ratio (HR) for COPD vs. no COPD 1.44 (1.21-1.72); P $<$ 0.001]. The effect of dapagliflozin, compared with placebo, on the primary outcome, was consistent in patients with [HR 0.67 (95% confidence interval 0.48-0.93)] and without COPD [0.76 (0.65-0.87); interaction P-value 0.47]. CONCLUSIONS: In DAPA-HF, one in eight patients with HFrEF had concomitant COPD. Participants with COPD had a higher risk of the primary outcome. The benefit of dapagliflozin on all pre-specified outcomes was consistent in patients with and without COPD. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov ID NCT03036124.

- OBJECTIVES: The purpose of this study was to assess the efficacy and safety of dapagliflozin in patients taking or not taking an mineralocorticoid receptor antagonist (MRA) at baseline in the DAPA-HF (Dapagliflozin And Prevention of Adverse outcomes in Heart Failure) trial. BACKGROUND: MRAs and sodium glucose co-transporter 2 inhibitors each have diuretic activity, lower blood pressure, and reduce glomerular filtration rate (GFR). Therefore, it is important to investigate the safety, as well as efficacy, of their combination. METHODS: A total of 4,744 patients with heart failure with reduced ejection fraction (HFrEF) were randomized to placebo or dapagliflozin 10 mg daily. The efficacy of dapagliflozin on the primary composite outcome (cardiovascular death or episode of worsening heart failure) and its components was examined according to MRA use, as were predefined safety outcomes. RESULTS: A total of 3,370 patients (71%) were treated with an MRA and they were younger (65 vs. 69 years of age), less often from North America (9% vs. 26%), had worse New York Heart Association functional class (35% vs. 25% in class III/IV), lower left ventricular ejection fraction (30.7% vs. 31.9%) and systolic blood pressure (120.3 vs. 125.5 mm Hg), but higher estimated GFR (67.1 vs. 62.6 ml/min/1.73 m(2)), than patients not taking an MRA. The benefit of dapagliflozin compared with placebo was similar in patients taking or not taking an MRA: hazard ratio: 0.74 (95% confidence interval [CI]: 0.63 to 0.87) versus 0.74 (95% CI: 0.57 to 0.95), respectively, for the primary endpoint (p value for interaction = 0.97); similar findings were observed for secondary endpoints. In both MRA subgroups, safety outcomes were similar in patients randomized to dapagliflozin or placebo. CONCLUSIONS: Dapagliflozin was similarly efficacious and safe in patients with HFrEF taking or not taking an MRA, supporting the use of both drugs together.
