Heart failure (HF) is one of the main causes of morbidity, mortality, and high healthcare costs. Dapagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, reduced cardiovascular mortality and hospitalization for HF compared to placebo in patients with chronic HF, and reduced ejection fraction (EF) in the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) study. Our aim was to estimate the number of patients with DAPA-HF characteristics in Spain. Our literature review identified epidemiological studies whose objective was to quantify the prevalence of HF and its comorbidities in Spain. We estimated the prevalence of HF with reduced EF, of New York Heart Association (NYHA) functional class II–IV, and with a glomerular filtration rate (GFR) ≥ 30 mL/min/1.73 m². In this population, we analysed the prevalence of diabetes using data from the REDINSCOR (Spanish Network for Heart Failure) registry. Our estimations indicate there are 594,684 patients ≥45 years old with HF in Spain (2.6% of this population age group), of which 52.4%, 84.0%, and 93.9% have reduced EF, are NYHA II–IV, and have a GFR ≥ 30 mL/min/1.73 m², respectively. By our calculations, approximately 245,789 Spanish patients would meet the DAPA-HF patient profile, and therefore could benefit from the protective cardiovascular effects of dapagliflozin.

First Time

Patients with heart failure with reduced ejection fraction (HFrEF), despite optimal evidence-based treatment, have a high residual risk of adverse outcomes. The favorable results of studies on cardiovascular safety and the effectiveness of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with type 2 diabetes (T2D), including outcomes associated with heart failure, were the reason for studying the effectiveness in patients with HFrEF regardless of the T2D status. For the first time in the DAPA-HF study, the SGLT2 inhibitor dapagliflozin in patients with HFrEF showed a positive effect on hard endpoints. Data of the secondary analysis confirmed the effectiveness of dapagliflozin regardless of the T2D status, therapy, age, and quality of life. The results of DAPA-HF have become a serious statement for changing the standards of the guideline-recommended therapy of HFrEF.

ObjectiveNew York Heart Association (NYHA) functional class plays a central role in heart failure (HF) assessment but might be unreliable in mild presentations. We compared objective measures of HF functional evaluation between patients classified as NYHA I and II in the Rede Brasileira de Estudos em Insuficiência Cardíaca (ReBIC)-1 Trial.MethodsThe ReBIC-1 Trial included outpatients with stable HF with reduced ejection fraction. All patients had simultaneous protocol-defined assessment of NYHA class, 6 min walk test (6MWT), N-terminal pro-brain natriuretic peptide (NT-proBNP) levels and patient’s self-perception of dyspnoea using a Visual Analogue Scale (VAS, range 0–100).ResultsOf 188 included patients with HF, 122 (65%) were classified as NYHA I and 66 (35%) as NYHA II at baseline. Although NYHA class I patients had lower dyspnoea VAS Scores (median 16 (IQR, 4–30) for class I vs 27.5 (11–49) for class II, p=0.001), overlap between classes was substantial (density overlap=60%). A similar profile was observed for NT-proBNP levels (620 pg/mL (248–1333) vs 778 (421–1737), p=0.015; overlap=78%) and for 6MWT distance (400 m (330–466) vs 351 m (286–408), p=0.028; overlap=64%). Among NYHA class I patients, 19%–34% had one marker of HF severity (VAS Score >30 points, 6MWT <300 m or NT-proBNP levels >1000 pg/mL) and 6%–10% had two of them. Temporal change in functional class was not accompanied by variation on dyspnoea VAS (p=0.14).ConclusionsMost patients classified as NYHA classes I and II had similar self-perception of their limitation, objective physical capabilities and levels of natriuretic peptides. These results suggest the NYHA classification poorly discriminates patients with mild HF.

BACKGROUND The New York Heart Association (NYHA) functional classification system has poor inter-rater reproducibility. A previously published pilot study showed a statistically significant difference between the daily step counts of heart failure (with reduced ejection fraction) patients classified as NYHA functional class II and III as measured by wrist-worn activity monitors. However, the study’s small sample size severely limits scientific confidence in the generalizability of this finding to a larger heart failure (HF) population. OBJECTIVE This study aimed to validate the pilot study on a larger sample of patients with HF with reduced ejection fraction (HFrEF) and attempt to characterize the step count distribution to gain insight into a more objective method of assessing NYHA functional class. METHODS We repeated the analysis performed during the pilot study on an independently recorded dataset comprising a total of 50 patients with HFrEF (35 NYHA II and 15 NYHA III) patients. Participants were monitored for step count with a Fitbit Flex for a period of 2 weeks in a free-living environment. RESULTS Comparing group medians, patients exhibiting NYHA class III symptoms had significantly lower recorded 2-week mean daily total step count (3541 vs 5729 [steps], P=.04), lower 2-week maximum daily total step count (10,792 vs 5904 [steps], P=.03), lower 2-week recorded mean daily mean step count (4.0 vs 2.5 [steps/minute], P=.04,), and lower 2-week mean and 2-week maximum daily per minute step count maximums (88.1 vs 96.1 and 111.0 vs 123.0 [steps/minute]; P=.02 and .004, respectively). CONCLUSIONS Patients with NYHA II and III symptoms differed significantly by various aggregate measures of free-living step count including the (1) mean and (2) maximum daily total step count as well as by the (3) mean of daily mean step count and by the (4) mean and (5) maximum of the daily per minute step count maximum. These findings affirm that the degree of exercise intolerance of NYHA II and III patients as a group is quantifiable in a replicable manner. This is a novel and promising finding that suggests the existence of a possible, completely objective measure of assessing HF functional class, something which would be a great boon in the continuing quest to improve patient outcomes for this burdensome and costly disease.

Heart failure (HF) and atrial fibrillation (AF) are the most common cardiovascular conditions in clinical practice and frequently coexist. The number of patients with HF and AF is increasing every year.Aim. To analyze the effect of clinical course and management of HF and AF on the outcomes.Material and methods. The data of 1,003 patients from the first Russian register of patients with HF and AF (RIF-CHF) were analyzed. The endpoints included hospitalization due to decompensated HF, cardiovascular mortality, thromboembolic events, and major bleeding. Predictors of unfavorable outcomes were analyzed separately for patients with HF with preserved ejection fraction (AF+HFpEF), mid-range ejection fraction (AF+HFmrEF), and reduced ejection fraction (AF+HFrEF).Results. Among all patients with HF, 39% had HFpEF, 15% — HFmrEF, and 46% — HFrEF. A total of 57,2% of patients were rehospitalized due to decompensated HF within one year. Hospitalization risk was the highest for HFmrEF patients (66%, p=0,017). Reduced ejection fraction was associated with the increased risk of cardiovascular mortality (15,5% vs 5,4% in other groups, p<0,001) but not ischemic stroke (2,4% vs 3%, p=0,776). Patients with HFpEF had lower risk to achieve the composite endpoint (stroke+MI+cardiovascular death) as compared to patients with HFmrEF and HFrEF (12,7% vs 22% and 25,5%, p<0,001). Regression logistic analysis revealed that factors such as demographic characteristics, disease severity, and selected therapy had different effects on the risk of unfavorable outcomes depending on ejection fraction group.Conclusion. Each group of patients with different ejection fractions is characterized by its own pattern of factors associated with unfavorable outcomes. The demographic and clinical characteristics of patients with mid-range ejection fraction demonstrate that these patients need to be studied as a separate cohort.

Background: Many patients with heart failure and reduced ejection fraction (HFrEF) have chronic kidney disease (CKD) which complicates pharmacological management and is associated with worse outcomes. We assessed the safety and efficacy of dapagliflozin in patients with HFrEF, according to baseline kidney function, in the Dapagliflozin and Prevention of Adverse-outcomes in Heart Failure trial (DAPA-HF). We also examined the effect of dapagliflozin on kidney function after randomization. Many patients with heart failure and reduced ejection fraction (HFrEF) have chronic kidney disease (CKD) which complicates pharmacological management and is associated with worse outcomes. We assessed the safety and efficacy of dapagliflozin in patients with HFrEF, according to baseline kidney function, in the Dapagliflozin and Prevention of Adverse-outcomes in Heart Failure trial (DAPA-HF). We also examined the effect of dapagliflozin on kidney function after randomization. Methods: HFrEF patients with or without type 2 diabetes and an estimated glomerular filtration rate (eGFR) ≥30 ml/min/1.73m 2 were enrolled in DAPA-HF. We calculated the incidence of the primary outcome (CV death or worsening HF) according to eGFR category at baseline (<60 and ≥60 ml/min/1.73m 2 ) as well as using eGFR at baseline as a continuous measure. Secondary cardiovascular outcomes and a pre-specified composite renal outcome (≥ 50% sustained decline eGFR, end stage renal disease (ESRD) or renal death) were also examined, along with decline in eGFR over time. Results: Of 4742 with a baseline eGFR, 1926 (41%) had eGFR <60 ml/min/1.73m 2 . The effect of dapagliflozin on the primary and secondary outcomes did not differ by eGFR category or examining eGFR as a continuous measurement. The hazard ratio (95% confidence interval (CI)) for the primary endpoint in patients with CKD was 0.71 (0.59, 0.86) vs. 0.77 (0.64, 0.93) in those with an eGFR ≥60 ml/min/1.73m 2 (interaction p=0.54). The composite renal outcome was not reduced by dapagliflozin (HR=0.71, 95% CI 0.44, 1.16; p=0.17) but the rate of decline in eGFR between day 14 and 720 was less with dapagliflozin, -1.09 (-1.41, -0.78) vs. placebo -2.87 (-3.19, -2.55) ml/min/1.73m 2 per year (p<0.001). This was observed in those with and without type 2 diabetes (p for interaction=0.92) Conclusions: Baseline kidney function did not modify the benefits of dapagliflozin on morbidity and mortality in HFrEF and dapagliflozin slowed the rate of decline in eGFR, including in patients without diabetes.

Background: Empagliflozin reduces the risk of cardiovascular death or hospitalization for heart failure in patients with heart failure and a reduced ejection fraction, with or without diabetes, but additional data are needed about the effect of the drug on inpatient and outpatient events that reflect worsening heart failure. Methods: We randomly assigned 3730 patients with class II-IV heart failure with an ejection fraction of ≤40% to double-blind treatment with placebo or empagliflozin (10 mg once daily), in addition to recommended treatments for heart failure, for a median of 16 months. We prospectively collected information on inpatient and outpatient events reflecting worsening heart failure and prespecified their analysis in individual and composite endpoints. Results: Empagliflozin reduced the combined risk of death, hospitalization for heart failure or an emergent/urgent heart failure visit requiring intravenous treatment (415 vs 519 patients; empagliflozin vs placebo, respectively; hazard ratio 0.76, 95% CI: 0.67-0.87), P <0.0001. This benefit reached statistical significance at 12 days after randomization. Empagliflozin reduced the total number of heart failure hospitalizations that required intensive care (hazard ratio 0.67, 95% CI 0.50-0.90, P=0.008) and that required a vasopressor or positive inotropic drug or mechanical or surgical intervention (hazard ratio 0.64, 95% CI: 0.47-0.87, P=0.005). As compared with placebo, fewer patients in the empagliflozin group reported intensification of diuretics (297 vs 414), hazard ratio 0.67, 95% CI: 0.56-0.78, P<0.0001. Additionally, patients assigned to empagliflozin were 20-40% more likely to experience an improvement in NYHA functional class and were 20-40% less likely to experience worsening of NYHA functional class, with statistically significant effects that were apparent 28 days after randomization and maintained during long-term follow-up. The risk of any inpatient or outpatient worsening heart failure event in the placebo group was high (48.1 per 100 patient-years of follow-up), and it was reduced by empagliflozin (hazard ratio 0.70, 95% CI: 0.63-0.78), P<0.0001. Conclusions: In patients with heart failure and a reduced ejection fraction, empagliflozin reduced the risk and total number of inpatient and outpatient worsening heart failure events, with benefits seen early after initiation of treatment and sustained for the duration of double-blind therapy.
