BACKGROUND Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of hospitalization for heart failure in patients regardless of the presence or absence of diabetes. More evidence is needed regarding the effects of these drugs in patients across the broad spectrum of heart failure, including those with a markedly reduced ejection fraction. METHODS In this double-blind trial, we randomly assigned 3730 patients with class II, III, or IV heart failure and an ejection fraction of 40% or less to receive empagliflozin (10 mg once daily) or placebo, in addition to recommended therapy. The primary outcome was a composite of cardiovascular death or hospitalization for worsening heart failure. RESULTS During a median of 16 months, a primary outcome event occurred in 361 of 1863 patients (19.4%) in the empagliflozin group and in 462 of 1867 patients (24.7%) in the placebo group (hazard ratio for cardiovascular death or hospitalization for heart failure, 0.75; 95% confidence interval [CI], 0.65 to 0.86; P<0.001). The effect of empagliflozin on the primary outcome was consistent in patients regardless of the presence or absence of diabetes. The total number of hospitalizations for heart failure was lower in the empagliflozin group than in the placebo group (hazard ratio, 0.70; 95% CI, 0.58 to 0.85; P<0.001). The annual rate of decline in the estimated glomerular filtration rate was slower in the empagliflozin group than in the placebo group (-0.55 vs.-2.28 ml per minute per 1.73 m 2 of body-surface area per year, P<0.001), and empagliflozin-treated patients had a lower risk of serious renal outcomes. Uncomplicated genital tract infection was reported more frequently with empagliflozin. CONCLUSIONS Among patients receiving recommended therapy for heart failure, those in the empagliflozin group had a lower risk of cardiovascular death or hospitalization for heart failure than those in the placebo group, regardless of the presence or absence of diabetes.

Frailty is a clinical state in which there is an increase in an individual’s vulnerability for developing increased dependency and/or mortality when exposed to a stressor. Frailty can occur as the result of a range of diseases and medical conditions. A consensus group consisting of delegates from 6 major international, European, and US societies created 4 major consensus points on a specific form of frailty: physical frailty. Physical frailty is an important medical syndrome. The group defined physical frailty as “a medical syndrome with multiple causes and contributors that is characterized by diminished strength, endurance, and reduced physiologic function that increases an individual’s vulnerability for developing increased dependency and/or death.”Physical frailty can potentially be prevented or treated with specific modalities, such as exercise, protein-calorie supplementation, vitamin D, and reduction of polypharmacy.Simple, rapid screening tests have been developed and validated, such as the simple FRAIL scale, to allow physicians to objectively recognize frail persons.For the purposes of optimally managing individuals with physical frailty, all persons older than 70 years and all individuals with significant weight loss (≥5%) due to chronic disease should be screened for frailty.
BACKGROUND Iron deficiency may impair aerobic performance. This study aimed to determine whether treatment with intravenous iron (ferric carboxymaltose) would improve symptoms in patients who had heart failure, reduced left ventricular ejection fraction, and iron deficiency, either with or without anemia. METHODS We enrolled 459 patients with chronic heart failure of New York Heart Association (NYHA) functional class II or III, a left ventricular ejection fraction of 40% or less (for patients with NYHA class II) or 45% or less (for NYHA class III), iron deficiency (ferritin level <100 μg per liter or between 100 and 299 μg per liter, if the transferrin saturation was <20%), and a hemoglobin level of 95 to 135 g per liter. Patients were randomly assigned, in a 2:1 ratio, to receive 200 mg of intravenous iron (ferric carboxymaltose) or saline (placebo). The primary end points were the self-reported Patient Global Assessment and NYHA functional class, both at week 24. Secondary end points included the distance walked in 6 minutes and the health-related quality of life. RESULTS Among the patients receiving ferric carboxymaltose, 50% reported being much or moderately improved, as compared with 28% of patients receiving placebo, according to the Patient Global Assessment (odds ratio for improvement, 2.51; 95% confidence interval [CI], 1.75 to 3.61). Among the patients assigned to ferric carboxymaltose, 47% had an NYHA functional class I or II at week 24, as compared with 30% of patients assigned to placebo (odds ratio for improvement by one class, 2.40; 95% CI, 1.55 to 3.71). Results were similar in patients with anemia and those without anemia. Significant improvements were seen with ferric carboxymaltose in the distance on the 6-minute walk test and quality-of-life assessments. The rates of death, adverse events, and serious adverse events were similar in the two study groups. CONCLUSIONS Treatment with intravenous ferric carboxymaltose in patients with chronic heart failure and iron deficiency, with or without anemia, improves symptoms, functional capacity, and quality of life; the side-effect profile is acceptable.

Aims The objectives of the present study were to describe epidemiology and outcomes in ambulatory heart failure (HF) patients stratified by left ventricular ejection fraction (LVEF) and to identify predictors for mortality at 1 year in each group. Methods and results The European Society of Cardiology Heart Failure Long‐Term Registry is a prospective, observational study collecting epidemiological information and 1‐year follow‐up data in 9134 HF patients. Patients were classified according to baseline LVEF into HF with reduced EF [EF <40% (HFrEF)], mid‐range EF [EF 40–50% (HFmrEF)] and preserved EF [EF >50% (HFpEF)]. In comparison with HFpEF subjects, patients with HFrEF were younger (64 years vs. 69 years), more commonly male (78% vs. 52%), more likely to have an ischaemic aetiology (49% vs. 24%) and left bundle branch block (24% vs. 9%), but less likely to have hypertension (56% vs. 67%) or atrial fibrillation (18% vs. 32%). The HFmrEF group resembled the HFrEF group in some features, including age, gender and ischaemic aetiology, but had less left ventricular and atrial dilation. Mortality at 1 year differed significantly between HFrEF and HFpEF (8.8% vs. 6.3%); HFmrEF patients experienced intermediate rates (7.6%). Age, New York Heart Association (NYHA) class III/IV status and chronic kidney disease predicted mortality in all LVEF groups. Low systolic blood pressure and high heart rate were predictors for mortality in HFrEF and HFmrEF. A lower body mass index was independently associated with mortality in HFrEF and HFpEF patients. Atrial fibrillation predicted mortality in HFpEF patients. Conclusions Heart failure patients stratified according to different categories of LVEF represent diverse phenotypes of demography, clinical presentation, aetiology and outcomes at 1 year. Differences in predictors for mortality might improve risk stratification and management goals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
