- 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: Circulating high-sensitivity cardiac troponin T (hsTnT) predominantly reflects myocardial injury, and higher levels are associated with a higher risk of worsening heart failure and death in patients with heart failure with reduced ejection fraction. Less is known about the prognostic significance of changes in hsTnT over time, the effects of dapagliflozin on clinical outcomes in relation to baseline hsTnT levels, and the effect of dapagliflozin on hsTnT levels. METHODS: DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) was a randomized, double-blind, placebo-controlled trial of dapagliflozin (10 mg daily) in patients with New York Heart Association class II to IV symptoms and left ventricular ejection fraction $<$/=40% (median follow-up, 18.2 months). hsTnT (Roche Diagnostics) was measured at baseline in 3112 patients and at 1 year in 2506 patients. The primary end point was adjudicated worsening heart failure or cardiovascular death. Clinical end points were analyzed according to baseline hsTnT and change in hsTnT from baseline to 1 year. Comparative treatment effects on clinical end points with dapagliflozin versus placebo were assessed by baseline hsTnT. The effect of dapagliflozin on hsTnT was explored. RESULTS: Median baseline hsTnT concentration was 20.0 (25th-75th percentile, 13.7-30.2) ng/L. Over 1 year, 67.9% of patients had a $>$/=10% relative increase or decrease in hsTnT concentrations, and 43.5% had a $>$/=20% relative change. A stepwise gradient of higher risk for the primary end point was observed across increasing quartiles of baseline hsTnT concentration (adjusted hazard ratio Q4 versus Q1, 3.44 [95% CI, 2.46-4.82]). Relative and absolute increases in hsTnT over 1 year were associated with higher subsequent risk of the primary end point. The relative reduction in the primary end point with dapagliflozin was consistent across quartiles of baseline hsTnT (P-interaction=0.55), but patients in the top quartile tended to have the greatest absolute risk reduction (absolute risk difference, 7.5% [95% CI, 1.0%-14.0%]). Dapagliflozin tended to attenuate the increase in hsTnT over time compared with placebo (relative least squares mean reduction, -3% [-6% to 0%]; P=0.076). CONCLUSIONS: Higher baseline hsTnT and greater increase in hsTnT over 1 year are associated with worse clinical outcomes. Dapagliflozin consistently reduced the risk of the primary end point, irrespective of baseline hsTnT levels. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03036124.

- BACKGROUND: Frailty may modify the risk-benefit profile of certain treatments, and frail patients may have reduced tolerance to treatments. OBJECTIVE: To investigate the efficacy of dapagliflozin according to frailty status, using the Rockwood cumulative deficit approach, in DAPA- HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure). DESIGN: Post hoc analysis of a phase 3 randomized clinical trial. (ClinicalTrials.gov: NCT03036124). SETTING: 410 sites in 20 countries. PATIENTS: Patients with symptomatic heart failure (HF) with a left ventricular ejection fraction of 40% or less and elevated natriuretic peptide. INTERVENTION: Addition of once-daily 10 mg of dapagliflozin or placebo to guideline-recommended therapy. MEASUREMENTS: The primary outcome was worsening HF or cardiovascular death. RESULTS: Of the 4744 patients randomly assigned in DAPA-HF, a frailty index (FI) was calculable in 4742. In total, 2392 patients (50.4%) were in FI class 1 (FI $<$/=0.210; not frail), 1606 (33.9%) in FI class 2 (FI 0.211 to 0.310; more frail), and 744 (15.7%) in FI class 3 (FI $>$/=0.311; most frail). The median follow-up time was 18.2 months. Dapagliflozin reduced the risk for worsening HF or cardiovascular death, regardless of FI class. The differences in event rate per 100 person-years for dapagliflozin versus placebo from lowest to highest FI class were -3.5 (95% CI, -5.7 to -1.2), -3.6 (CI, -6.6 to -0.5), and -7.9 (CI, -13.9 to -1.9). Consistent benefits were observed for other clinical events and health status, but the absolute reductions were generally larger in the most frail patients. Study drug discontinuation and serious adverse events were not more frequent with dapagliflozin than placebo, regardless of FI class. LIMITATION: Enrollment criteria precluded the inclusion of very high-risk patients. CONCLUSION: Dapagliflozin improved all outcomes examined, regardless of frailty status. However, the absolute reductions were larger in more frail patients. PRIMARY FUNDING SOURCE: AstraZeneca.

- 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.

- In the DAPA-HF trial, the SGLT2 inhibitor dapagliflozin reduced the risk of worsening heart failure (HF) and death in patients with HF and reduced ejection fraction. We examined whether this benefit was consistent in relation to background HF therapy.In this post hoc analysis, we examined the effect of study treatment in the following yes/no subgroups: diuretic, digoxin, mineralocorticoid receptor antagonist (MRA), sacubitril/valsartan, ivabradine, implanted cardioverter-defibrillating (ICD) device, and cardiac resynchronization therapy. We also examined the effect of study drug according to angiotensin-converting enzyme inhibitor/angiotensin receptor blocker dose, beta-blocker (BB) dose, and MRA (≥50% and <50% of target dose). We analysed the primary composite endpoint of cardiovascular death or a worsening HF event. Most randomized patients (n=4744) were treated with a diuretic (84%), renin-angiotensin system (RAS) blocker (94%), and BB (96%); 52% of those taking a BB and 38% taking a RAS blocker were treated with ≥50% of the recommended dose. Overall, the dapagliflozin vs. placebo hazard ratio (HR) was 0.74 [95% confidence interval (CI) 0.65-0.85] for the primary composite endpoint (P<0.0001). The effect of dapagliflozin was consistent across all subgroups examined: the HR ranged from 0.57 to 0.86 for primary endpoint, with no significant randomized treatment-by-subgroup interaction. For example, the HR in patients taking a RAS blocker, BB, and MRA at baseline was 0.72 (95% CI 0.61-0.86) compared with 0.77 (95% CI 0.63-0.94) in those not on all three of these treatments (P-interaction 0.64).The benefit of dapagliflozin was consistent regardless of background therapy for HF.

Iron Deficiency in Heart Failure and Effect of Dapagliflozin : Findings From DAPA-HF.
- 2022

Ingår i: Circulation. ; 146:13, s. 980-994
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Iron deficiency is common in heart failure and associated with worse outcomes. We examined the prevalence and consequences of iron deficiency in the DAPA-HF trial (Dapagliflozin and Prevention of Adverse- Outcomes in Heart Failure) and the effect of dapagliflozin on markers of iron metabolism. We also analyzed the effect of dapagliflozin on outcomes, according to iron status at baseline. METHODS: Iron deficiency was defined as a ferritin level $<$100 ng/mL or a transferrin saturation $<$20% and a ferritin level 100 to 299 ng/mL. Additional biomarkers of iron metabolism, including soluble transferrin receptor, erythropoietin, and hepcidin were measured at baseline and 12 months after randomization. The primary outcome was a composite of worsening heart failure (hospitalization or urgent visit requiring intravenous therapy) or cardiovascular death. RESULTS: Of the 4744 patients randomized in DAPA- HF, 3009 had ferritin and transferrin saturation measurements available at baseline, and 1314 of these participants (43.7%) were iron deficient. The rate of the primary outcome was higher in patients with iron deficiency (16.6 per 100 person-years) compared with those without (10.4 per 100 person-years; P$<$0.0001). The effect of dapagliflozin on the primary outcome was consistent in iron-deficient compared with iron- replete patients (hazard ratio, 0.74 [95% CI, 0.58-0.92] versus 0.81 [95% CI, 0.63-1.03]; P-interaction=0.59). Similar findings were observed for cardiovascular death, heart failure hospitalization, and all-cause mortality. Transferrin saturation, ferritin, and hepcidin were reduced and total iron-binding capacity and soluble transferrin receptor increased with dapagliflozin compared with placebo. CONCLUSIONS: Iron deficiency was common in DAPA-HF and associated with worse outcomes. Dapagliflozin appeared to increase iron use but improved outcomes, irrespective of iron status at baseline.

- Objective To compare the Danish Emergency Process Triage (DEPT) with a quick clinical assessment (Eyeball triage) as predictors of short-term mortality in patients in the emergency department (ED).Methods The investigation was designed as a prospective cohort study conducted at North Zealand University Hospital. All patient visits to the ED from September 2013 to December 2013 except minor injuries were included. DEPT was performed by nurses. Eyeball triage was a quick non-systematic clinical assessment based on patient appearance performed by phlebotomists. Both triage methods categorised patients as green (not urgent), yellow, orange or red (most urgent). Primary analysis assessed the association between triage level and 30-day mortality for each triage method. Secondary analyses investigated the relation between triage level and 48-hour mortality as well as the agreement between DEPT and Eyeball triage.Results A total of 6383 patient visits were included. DEPT was performed for 6290 (98.5%) and Eyeball triage for 6382 (~100%) of the patient visits. Only patients with both triage assessments were included. The hazard ratio (HR) for 48-hour mortality for patients categorised as yellow was 0.9 (95% CI 0.4 to 1.9) for DEPT compared with 4.2 (95% CI 1.2 to 14.6) for Eyeball triage (green is reference). For orange the HR for DEPT was 2.2 (95% CI 1.1 to 4.4) and 17.1 (95% CI 5.1 to 57.1) for Eyeball triage. For red the HR was 30.9 (95% CI 12.3 to 77.4) for DEPT and 128.7 (95% CI 37.9 to 436.8) for Eyeball triage. For 30-day mortality the HR for patients categorised as yellow was 1.7 (95% CI 1.2 to 2.4) for DEPT and 2.4 (95% CI 1.6 to 3.5) for Eyeball triage. For orange the HR was 2.6 (95% CI 1.8 to 3.6) for DEPT and 7.6 (95% CI 5.1 to 11.2) for Eyeball triage, and for red the HR was 19.1 (95% CI 10.4 to 35.2) for DEPT and 27.1 (95% CI 16.9 to 43.5) for Eyeball triage. Agreement between the two systems was poor (kappa 0.05).Conclusion Agreement between formalised triage and clinical assessment is poor. A simple clinical assessment by phlebotomists is superior to a formalised triage system to predict short-term mortality in ED patients.
