Background: Sodium-glucose cotransporter-2 inhibitors have emerged as a key pharmacotherapy in heart failure (HF) with both reduced and preserved ejection fraction. The benefit of other HF therapies may be modified by sex, but whether sex modifies the treatment effect and safety profile of sodium-glucose cotransporter-2 inhibitors remains unclear. Our analyses aim to assess the effect of sex on the efficacy and safety of dapagliflozin. Methods: In a prespecified patient-level pooled analysis of DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure), clinical outcomes were compared by sex (including the composite of cardiovascular death or worsening HF events, cardiovascular death, all-cause death, total events [first and recurrent HF hospitalization and cardiovascular death], and Kansas City Cardiomyopathy Questionnaire scores) across the spectrum of left ventricular ejection fraction. Results: Of a total of 11 007 randomized patients, 3856 (35%) were women. Women with HF were older and had higher body mass index but were less likely to have a history of diabetes and myocardial infarction or stroke and more likely to have hypertension and atrial fibrillation compared with men. At baseline, women had higher ejection fraction but worse Kansas City Cardiomyopathy Questionnaire scores than men did. After adjustment for baseline differences, women were less likely than men to experience cardiovascular death (adjusted hazard ratio, 0.69 [95% CI, 0.60-0.79]), all-cause death (adjusted hazard ratio, 0.69 [95% CI, 0.62-0.78]), HF hospitalizations (adjusted hazard ratio, 0.82 [95% CI, 0.72-0.94]), and total events (adjusted rate ratio, 0.77 [95% CI, 0.71-0.84]). Dapagliflozin reduced the primary end point in both men and women similarly (Pinteraction=0.77) with no sex-related differences in secondary outcomes (all Pinte

Importance: Gout is common in patients with heart failure (HF), and sodium-glucose cotransporter 2 inhibitors, a foundational treatment for HF, reduce uric acid levels. Objective: To examine the reported prevalence of gout at baseline, the association between gout and clinical outcomes, and the effect of dapagliflozin in patients with and without gout and the introduction of new uric acid-lowering therapy and colchicine. Design, Setting, and Participants: This post hoc analysis used data from 2 phase 3 randomized clinical trials conducted in 26 countries, DAPA-HF (left ventricular ejection fraction [LVEF] ≤40%) and DELIVER (LVEF >40%). Patients with New York Heart Association functional class II through IV and elevated levels of N-terminal pro-B-type natriuretic peptide were eligible. Data were analyzed between September 2022 and December 2022. Intervention: 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 worsening HF or cardiovascular death. Results: Among 11005 patients for whom gout history was available, 1117 patients (10.1%) had a history of gout. The prevalence of gout was 10.3% (488 of 4747 patients) and 10.1% (629 of 6258 patients) in those with an LVEF up to 40% and greater than 40%, respectively. Patients with gout were more often men (897 of 1117 [80.3%]) than those without (6252 of 9888 [63.2%]). The mean (SD) age was similar between groups, 69.6 (9.8) years for patients with gout and 69.3 (10.6) years for those without. Patients with a history of gout had a higher body mass index, more comorbidity, and lower estimated glomerular filtration rate and were more often treated with a loop diuretic. The primary outcome occurred at a rate of 14.7 per 100 person-years (95% CI, 13.0-16.5) in participants with gout compared with 10.5 per 100 person-years (95% CI, 10.1-11.0) in those without (adjusted hazard ratio [HR], 1.15; 95% CI, 1.01-1.31). A

Background: Sodium-glucose cotransporter-2 (SGLT2) inhibitors are guideline recommended in the management of heart failure (HF). Although these therapies can be initiated even in patients with comorbid chronic kidney disease, some patients may face deterioration of kidney function over time. Objectives: In this study, the authors sought to examine the safety and efficacy of continuing SGLT2 inhibitors in HF when the estimated glomerular filtration rate (eGFR) falls below thresholds for initiation. Methods: Associations between a deterioration of eGFR to <25 mL/min/1.73 m2, efficacy, and safety outcomes and treatment with dapagliflozin were evaluated in time-updated Cox proportional hazard models in a participant-level pooled analysis of the DAPA-HF (Study to Evaluate the Effect of Dapagliflozin on the Incidence of Worsening Heart Failure or Cardiovascular Death in Patients With Chronic Heart Failure) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trials. Results: Among 11,007 patients, 347 (3.2%) experienced a deterioration of eGFR to <25 mL/min/1.73 m2 at least once in follow-up. These patients had a higher risk of the primary composite outcome (HR: 1.87; 95% CI: 1.48-2.35; P < 0.001). The risk of the primary outcome was lower with dapagliflozin compared with placebo among patients who did (HR: 0.53; 95% CI: 0.33-0.83) as well as did not (HR: 0.78; 95% CI: 0.72-0.86) experience deterioration of eGFR to <25 mL/min/1.73 m2 (Pinteraction = 0.17). The risk of safety outcomes, including drug discontinuation, was higher among patients with deterioration of eGFR to <25 mL/min/1.73 m2; however, rates remained similar between treatment groups including among those who remained on study drug. Conclusions: Patients with deterioration of eGFR to <25 mL/min/1.73 m2 had elevated risks of cardiovascular outcomes yet appeare

Background: Because clinical characteristics and prognosis vary by geographic region in patients with heart failure (HF), the response to treatment may also vary. A previous report suggested that the efficacy of sodium-glucose cotransporter-2 inhibitor efficacy in heart failure with reduced ejection fraction (HFrEF) may be modified by region. Objectives: The goal of this study was to examine the efficacy and safety of dapagliflozin in patients with HF according to geographic region. Methods: We conducted a patient-level pooled analysis of the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure) trials, which evaluated the effects of dapagliflozin in HFrEF and heart failure with mildly reduced ejection fraction (HFmrEF)/heart failure with preserved ejection fraction (HFpEF), respectively. The primary outcome was the composite of worsening HF or cardiovascular death. Results: Among 11,007 patients, 5,159 (46.9%) were enrolled in Europe, 1,528 (13.9%) in North America, 1,998 (18.2%) in South America, and 2,322 (21.1%) in Asia. The rate of the primary outcome (per 100 person-years) was higher in North America (13.9 [95% CI: 12.5-15.4]) than in other regions: Europe 10.8 (95% CI: 10.1-11.5), South America 10.0 (95% CI: 9.0-11.1), and Asia 10.5 (95% CI: 9.5-11.5). The benefit of dapagliflozin on the primary outcome was not modified by region: dapagliflozin vs placebo HR: Europe, 0.85 (95% CI: 0.75-0.96); North America, 0.75 (95% CI: 0.61-0.93); South America, 0.72 (95% CI: 0.58-0.89); and Asia, 0.74 (95% CI: 0.61-0.91) (P interaction = 0.40). This was the same when evaluated separately for HFrEF (P interaction = 0.39) and HFmrEF/HFpEF (P interaction = 0.84). Patients in North America discontinued randomized treatment more frequently than did those elsewhere (placebo discontinuation: 21.8% in North America vs 6.4% in South America

BACKGROUND: The primary end point in most heart failure (HF) trials is a composite of time to a first worsening HF event or cardiovascular death. Prevention of recurrent events and improvements in symptoms/quality of life are also important for patients but are usually analyzed separately. Win statistics can integrate all these outcomes into a single composite end point, which is analyzed in hierarchical order, reflecting the clinical importance of each component. METHODS: The Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF, n=4744) and Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure (DELIVER, n=6263) trials enrolled patients with New York Heart Association class II, III, or IV HF, elevated natriuretic peptides, and either an ejection fraction of 40% or less (DAPA-HF) or greater than 40% and left atrial enlargement/left ventricular hypertrophy (DELIVER). We examined the effects of dapagliflozin compared with placebo on a hierarchical composite outcome, including cardiovascular death, total (first and recurrent) HF hospitalizations, total urgent HF visits, and improvement/deterioration in Kansas City Cardiomyopathy Questionnaire total symptom score (KCCQ-TSS; range from 0 to 100, with a higher score indicating fewer symptoms and physical limitations) at 8 months. RESULTS: For this composite outcome, the win ratio was 1.30 (95% confidence interval [CI], 1.23 to 1.36) in the pooled cohort, 1.33 (95% CI, 1.23 to 1.43) in the DAPA-HF trial, and 1.27 (95% CI, 1.18 to 1.36) in the DELIVER trial. Win odds and net benefit in overall patients were 1.19 (95% CI, 1.14 to 1.24) and 8.7% (95% CI, 6.6 to 10.9%), respectively. In the overall pooled cohort, the majority of wins and losses were accounted for by KCCQ-TSS; 52.4% were settled by the KCCQ-TSS tier in the pooled cohort. CONCLUSIONS: In both the DAPA-HF and DELIVER trials, dapagliflozin led to a significant improvement in composite outco

Background: Black people have a higher incidence and prevalence of heart failure (HF) than White people, and once HF has developed, they may have worse outcomes. There is also evidence that the response to several pharmacologic therapies may differ between Black and White patients. Objectives: The authors sought to examine the outcomes and response to treatment with dapagliflozin according to Black or White race in a pooled analysis of 2 trials comparing dapagliflozin to placebo in patients with heart failure with reduced ejection fraction (DAPA-HF [Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure]) and heart failure with mildly reduced ejection fraction/heart failure with preserved ejection fraction (DELIVER [Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure]). Methods: Because most self-identified Black patients were enrolled in the Americas, the comparator group was White patients randomized in the same regions. The primary outcome was the composite of worsening HF or cardiovascular death. Results: Of the 3,526 patients randomized in the Americas, 2,626 (74.5%) identified as White and 381 (10.8%) as Black. The primary outcome occurred at a rate of 16.8 (95% CI: 13.8-20.4) in Black patients compared with 11.6 (95% CI: 10.6-12.7) per 100 person-years in White patients (adjusted HR: 1.27; 95% CI: 1.01-1.59). Compared with placebo, dapagliflozin decreased the risk of the primary endpoint to the same extent in Black (HR: 0.69; 95% CI: 0.47-1.02) and White patients (HR: 0.73 [95% CI: 0.61-0.88]; Pinteraction = 0.73). The number of patients needed to treat with dapagliflozin to prevent one event over the median follow-up was 17 in White and 12 in Black patients. The beneficial effects and favorable safety profile of dapagliflozin were consistent across the range of left ventricular ejection fractions in both Black and White patients. Conclusions: The relative benefits of dapagliflozin

BACKGROUND: Although elevated resting heart rate (HR) is associated with a higher risk of cardiovascular events in patients with heart failure with reduced ejection fraction in sinus rhythm (SR), the relationship between HR and outcomes among patients with heart failure with mildly reduced ejection fraction/heart failure with preserved ejection fraction and in those with atrial fibrillation (AF) is uncertain. The aims of this study were to examine the association between baseline HR and outcomes across the range of left ventricular ejection fraction, in patients with and without AF, and evaluate the effect of dapagliflozin according to HR. METHODS: A patient-level pooled analysis of the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure; heart failure with reduced ejection fraction) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure trial; heart failure with mildly reduced ejection fraction/heart failure with preserved ejection fraction) trials. The primary outcome of each was the composite of worsening heart failure or cardiovascular death. RESULTS: Among patients with SR (n=6401, 64%), the rate of the primary outcome was higher in those with higher HR: 16.8 versus 7.7 per 100 person-years for ≥80 bpm versus <60 bpm. The relationship between HR and risk was steeper in heart failure with reduced ejection fraction versus heart failure with mildly reduced ejection fraction/heart failure with preserved ejection fraction. HR was not associated with outcomes in patients in AF for either heart failure phenotype. The benefit of dapagliflozin on the primary outcome was consistent across the HR range in both SR (Pinteraction=0.28) and AF (Pinteraction=0.56), for example, for SR <60 bpm, hazard ratio for dapagliflozin versus placebo 0.72 (95% CI, 0.55-0.95); 60 to 69 bpm, 0.78 (0.63-0.97); 70 to 79 bpm, 0.73 (0.59-0.91); ≥80 bpm, 0.77 (0.61-0.97). The bene

Background Multimorbidity (two or more comorbidities) is common among patients with acute heart failure, but comprehensive global information on its prevalence and clinical consequences across different world regions and income levels is scarce. This study aimed to investigate the prevalence of multimorbidity and its effect on pharmacotherapy and prognosis in participants of the REPORT-HF study.Methods REPORT-HF was a prospective, multicentre, global cohort study that enrolled adults (aged >= 18 years) admitted to hospital with a primary diagnosis of acute heart failure from 358 hospitals in 44 countries on six continents. Patients who currently or recently participated in a clinical treatment trial were excluded. Follow-up data were collected at 1-year post-discharge. The primary outcome was 1-year post-discharge mortality. All patients in the REPORT-HF cohort with full data on comorbidities were eligible for the present study. We stratified patients according to the number of comorbidities, and countries by world region and country income level. We used one-way ANOVA, chi(2) test, or Mann-Whitney U test for comparisons between groups, as applicable, and Cox regression to analyse the association between multimorbidity and 1-year mortality.Findings Between July 23, 2014, and March 24, 2017, 18 553 patients were included in the REPORT-HF study. Of these, 18 528 patients had full data on comorbidities, of whom 11 360 (61%) were men and 7168 (39%) were women. Prevalence rates of multimorbidity were lowest in southeast Asia (72%) and highest in North America (92%). Fewer patients from lower-middle-income countries had multimorbidity than patients from high-income countries (73% vs 85%, p<0 center dot 0001). With increasing comorbidity burden, patients received fewer guideline-directed heart failure medications, yet more drugs potentially causing or worsening heart failure. Having more comorbidities was associated with worse outcomes: 1-year mortality incre, Funding Agencies|Novartis Pharma; Forderkreis der Dresdner Herz-Kreislauf-Tage; German Center for Cardiovascular Research; German Research Foundation (DFG) [GE 3588/1-1, GE 3179/1-1]; German Society of Internal Medicine; National University of Singapore; Ministry of Education; National Medical Research Council

Aims STRONG‐HF examined a high‐intensity care (HIC) strategy of rapid up‐titration of guideline‐directed medical therapy (GDMT) and close follow‐up after acute heart failure (AHF) admission. We assess the role of age on efficacy and safety of HIC. Methods and results Hospitalized AHF patients, not treated with optimal GDMT were randomized to HIC or usual care. The primary endpoint of 180‐day death or HF readmission occurred equally in older (>65 years, n = 493, 74 ± 5 years) and younger patients (53 ± 11 years, adjusted hazard ratio [aHR] 1.02, 95% confidence interval [CI] 0.73–1.43, p = 0.89). Older patients received slightly lower GDMT to day 21, but same doses at day 90 and 180. The effect of HIC on the primary endpoint was numerically higher in younger (aHR 0.51, 95% CI 0.32–0.82) than older patients (aHR 0.73, 95% CI 0.46–1.15, adjusted interaction p = 0.30), partially related to COVID‐19 deaths. After exclusion of COVID‐19 deaths, the effect of HIC was similar in younger (aHR 0.51, 95% CI 0.32–0.82) and older patients (aHR 0.63, 95% CI 0.32–1.02, adjusted interaction p = 0.56), with no treatment‐by‐age interaction (interaction p = 0.57). HIC induced larger improvements in quality of life to day 90 in younger (EQ‐VAS adjusted‐mean difference 5.51, 95% CI 3.20–7.82) than in older patients (1.77, 95% CI −0.75 to 4.29, interaction p = 0.032). HIC was associated with similar rates of adverse events in older and younger patients. Conclusion High‐intensity care after AHF was safe and resulted in a significant reduction of all‐cause death or HF readmission at 180 days across the study age spectrum. Older patients have smaller benefits in terms of quality of life.

Aims Hospital admission during nighttime and off hours may affect the outcome of patients with various cardiovascular conditions due to suboptimal resources and personnel availability, but data for acute heart failure remain controversial. Therefore, we studied outcomes of acute heart failure patients according to their time of admission from the global International Registry to assess medical practice with lOngitudinal obseRvation for Treatment of Heart Failure.Methods and results Overall, 18 553 acute heart failure patients were divided according to time of admission into morning (7:00-14:59), evening (15:00-22:59), and night (23:00-06:59) shift groups. Patients were also dichotomized to admission during working hours (9:00-16:59 during standard working days) and non-working hours (any other time). Clinical characteristics, treatments, and outcomes were compared across groups. The hospital length of stay was longer for morning (odds ratio: 1.08; 95% confidence interval: 1.06-1.10, P < 0.001) and evening shift (odds ratio: 1.10; 95% confidence interval: 1.07-1.12, P < 0.001) as compared with night shift. The length of stay was also longer for working vs. non-working hours (odds ratio: 1.03; 95% confidence interval: 1.02-1.05, P < 0.001). There were no significant differences in in-hospital mortality among the groups. Admission during working hours, compared with non-working hours, was associated with significantly lower mortality at 1 year (hazard ratio: 0.88; 95% confidence interval: 0.80-0.96, P = 0.003).Conclusions Acute heart failure patients admitted during the night shift and non-working hours had shorter length of stay but similar in-hospital mortality. However, patients admitted during non-working hours were at a higher risk for 1 year mortality. These findings may have implications for the health policies and heart failure trials., Funding Agencies|Novartis

Background: In heart failure (HF), symptoms and health-related quality of life (HRQoL) are known to vary among different HF subgroups, but evidence on the association between changing HRQoL and outcomes has not been evaluated. Objectives: The authors sought to investigate the relationship between changing symptoms, signs, and HRQoL and outcomes by sex, ethnicity, and socioeconomic status (SES). Methods: Using the ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) Registry, we investigated associations between the 6-month change in a "global" symptoms and signs score (GSSS), Kansas City Cardiomyopathy Questionnaire overall score (KCCQ-OS), and visual analogue scale (VAS) and 1-year mortality or HF hospitalization. Results: In 6,549 patients (mean age: 62 ± 13 years], 29% female, 27% HF with preserved ejection fraction), women and those in low SES groups had higher symptom burden but lower signs and similar KCCQ-OS to their respective counterparts. Malay patients had the highest GSSS (3.9) and lowest KCCQ-OS (58.5), and Thai/Filipino/others (2.6) and Chinese patients (2.7) had the lowest GSSS scores and the highest KCCQ-OS (73.1 and 74.6, respectively). Compared to no change, worsening of GSSS (>1-point increase), KCCQ-OS (≥10-point decrease) and VAS (>1-point decrease) were associated with higher risk of HF admission/death (adjusted HR: 2.95 [95% CI: 2.14-4.06], 1.93 [95% CI: 1.26-2.94], and 2.30 [95% CI: 1.51-3.52], respectively). Conversely, the same degrees of improvement in GSSS, KCCQ-OS, and VAS were associated with reduced rates (HR: 0.35 [95% CI: 0.25-0.49], 0.25 [95% CI: 0.16-0.40], and 0.64 [95% CI: 0.40-1.00], respectively). Results were consistent across all sex, ethnicity, and SES groups (interaction P > 0.05). Conclusions: Serial measures of patient-reported symptoms and HRQoL are significant and consistent predictors of outcomes among different groups with HF and provide the potential for a patient-centered and pragmatic approach to risk st
