Background: About half of patients with heart failure with mildly reduced or preserved ejection fraction (HFpEF) have type 2 diabetes. In the STEP-HFpEF DM trial of adults with obesity-related HFpEF and type 2 diabetes, subcutaneous once weekly semaglutide 2·4 mg conferred improvements in heart failure-related symptoms and physical limitations, bodyweight, and other heart failure outcomes. We aimed to determine whether these effects of semaglutide differ according to baseline HbA.

Aims: A cardiovascular magnetic resonance (CMR) approach to non-invasively estimate left ventricular (LV) filling pressure was recently developed and shown to correlate with invasively measured pulmonary capillary wedge pressure (PCWP). We examined the association between CMR-estimated PCWP (CMR-PCWP) and other imaging and biomarker measures of congestion, and the effect of empagliflozin on these, in the SUGAR-DM-HF trial (NCT03485092).

Methods And Results: SUGAR-DM-HF enrolled 105 patients with heart failure with reduced ejection fraction (HFrEF) and pre-diabetes or type 2 diabetes who were randomly assigned to empagliflozin 10 mg or placebo once daily for 36 weeks.

Aims: In the EMPACT-MI trial, empagliflozin reduced heart failure (HF) hospitalizations but not mortality in acute myocardial infarction (MI). Contemporary reports of clinical event rates with and without type 2 diabetes mellitus (T2DM) in acute MI trials are sparse. The treatment effect of empagliflozin in those with and without T2DM in acute MI is unknown.

Anthracyclines, such as doxorubicin, are important anti-cancer therapies but are associated with arterial injury. Histopathological insights have been limited to small animal models, and the role of inflammation in the arterial toxic effects of anthracycline is unclear in humans. Our aims were (1) to evaluate aortic media fibrosis and injury in non-human primates treated with anthracyclines; (2) to assess the effect of anthracycline on aortic inflammation in patients treated for lymphoma.

Aims: Patients with a reduced left ventricular ejection fraction (LVEF) following an acute myocardial infarction (MI) are considered to be at risk of progressive adverse cardiac remodelling which can lead to the development of heart failure and death. The early addition of a sodium-glucose cotransporter 2 (SGLT2) inhibitor to standard treatment may delay or prevent progressive adverse remodelling in these patients.

Methods And Results: We performed a randomized, double-blind, placebo-controlled, multicentre trial using cardiovascular magnetic resonance imaging (MRI), in patients with left ventricular systolic dysfunction following MI.

Background: Obesity is associated with excessive adipocyte-derived aldosterone secretion, independent of the classical renin-angiotensin-aldosterone cascade, and mineralocorticoid receptor antagonists may be more effective in patients with heart failure (HF) and obesity.

Objectives: This study sought to examine the effects of the nonsteroidal mineralocorticoid receptor antagonist finerenone compared with placebo, according to body mass index (BMI) in FINEARTS-HF (FINerenone trial to investigate Efficacy and sAfety superioR to placebo in paTientS with Heart Failure).

Methods: A total of 6,001 patients with HF with NYHA functional class II, III, and IV, a left ventricular ejection fraction of ≥40%, evidence of structural heart disease, and elevated natriuretic peptide levels were randomized to finerenone or placebo.

Background: Predicting the success of a Debridement, Antibiotics, and Implant Retention (DAIR) procedure for periprosthetic joint infection (PJI) for hip and knee joint arthroplasty remains a challenge. A failed DAIR might adversely affect the outcome of any future revision surgery for PJI. Hence, the ability to identify and optimize factors predictive of DAIR success would help target the procedure to the appropriate patient cohort and avoid unnecessary surgery for patients where a DAIR is unlikely to eradicate infection.

Article Synopsis
  • Mineralocorticoid receptor antagonists (MRA) like spironolactone are effective for heart failure with reduced ejection fraction but are often underused due to hyperkalemia concerns.
  • The REALIZE-K trial tested the effects of sodium zirconium cyclosilicate (SZC) in helping patients with heart failure and hyperkalemia effectively use spironolactone.
  • Results showed that participants who received SZC had significantly better outcomes in terms of maintaining normal potassium levels and continuing on spironolactone compared to those on a placebo.

Background And Aim: Intravenous loop diuretics are the primary treatment for congestion in patients with decompensated heart failure (HF). Furosemide is the most commonly used loop diuretic and is licensed for administration either orally, intramuscularly or intravenously but not subcutaneously. Recently developed, pH-neutral, concentrated, 'skin-friendly' preparations of furosemide have been developed which allow subcutaneous administration.

Introduction: The high risk of cardiovascular events in people with type 2 diabetes increases with age. The cardiovascular effects of once-weekly subcutaneous and once-daily oral semaglutide versus placebo in people with type 2 diabetes at high cardiovascular risk were investigated in the SUSTAIN 6 and PIONEER 6 cardiovascular outcomes trials, respectively. It is unknown whether the effects of semaglutide are age dependent.

Article Synopsis
  • Heart failure events in cardiovascular trials are often evaluated through centralized review, but its impact on treatment effect accuracy (in terms of hazard ratios) is uncertain.
  • In a study of seven trials, positive adjudication rates for heart failure events were generally lower than for cardiovascular deaths, affecting subsequent mortality risk.
  • Overall, while central adjudication showed some correlation between event types, it didn’t significantly change the results, suggesting that the need for centralized review should be tailored to each trial's objectives.

Article Synopsis
  • Left ventricular assist devices (LVADs) are commonly used to treat advanced heart failure, improving survival but leading to high rates of arrhythmias (20-50%) within a year after implantation.
  • Arrhythmias in these patients increase the risk of complications, such as additional shocks from implantable defibrillators and potential worsening of right ventricular failure, highlighting the need for tailored management strategies.
  • Effective treatment for these arrhythmias may involve specialized approaches like catheter ablation, though unique challenges exist in accessing arrhythmogenic areas after LVAD surgery, making pre-implantation procedures potentially beneficial.

Aims: Concerns exist that intravenous (IV) iron might increase the risk of infections. The IRONMAN trial provided an opportunity to investigate whether giving IV ferric derisomaltose (FDI) to patients with heart failure and iron deficiency alters the rate of hospitalization or death due to infections.

Methods And Results: IRONMAN was a randomized trial of IV FDI versus usual care in patients with symptomatic heart failure, left ventricular ejection fraction (LVEF) ≤45%, and transferrin saturation (TSAT) <20% or ferritin <100 μg/L.

Background: As future cardiovascular disease mortality trends have public health implications, we aimed to project ischemic heart disease (IHD), cerebrovascular disease (CeVD), and heart failure (HF) mortality rates for adults (40-79 years).

Methods And Results: In this population-level study, we linked the yearly mortality rates (per 100 000 US residents) (2000-2019) with IHD, CeVD, or HF as the primary cause of death from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research with the midyear US population estimates (2000-2035) for adults (40-79 years). We calculated the observed age-standardized mortality rates (2000-2019) (per 100 000 residents) (aSMR) and fitted Bayesian age-period-cohort models to project aSMR for IHD, CeVD, and HF up to 2035 in the United States.

Article Synopsis
  • Finerenone demonstrates positive outcomes for patients with heart failure and varying degrees of ejection fraction, specifically HFmrHF and HFpEF, in a large clinical trial involving 6,001 participants aged 40-97.
  • The analysis revealed that while the incidence of adverse cardiovascular outcomes increased with age, finerenone consistently reduced the risk of these outcomes across all age groups.
  • Safety profiles, including the occurrence of hypotension and changes in potassium levels, showed no significant differences among age categories, suggesting that finerenone is safe and effective regardless of age.

People with a spinal cord injury are at an increased risk of metabolic dysfunction due to skeletal muscle atrophy and the transition of paralyzed muscle to a glycolytic, insulin-resistant phenotype. Providing doses of exercise through electrical muscle stimulation may provide a therapeutic intervention to help restore metabolic function for people with a spinal cord injury, but high-frequency and high-force electrically induced muscle contractions increase fracture risk for the underlying osteoporotic skeletal system. Therefore, we investigated the acute molecular responses after a session of either a 3 Hz or 1 Hz electrically induced exercise program.

Article Synopsis
  • Steroidal mineralocorticoid receptor antagonists help patients with heart failure and reduced ejection fraction, but their effectiveness in those with mildly reduced or preserved ejection fraction is unclear, indicating a need for further research on finerenone.
  • In a double-blind study, patients with heart failure (ejection fraction 40% or greater) were assigned to receive either finerenone or a placebo to assess its impact on heart failure events and cardiovascular death.
  • Results showed that finerenone led to fewer worsening heart failure events and a lower overall rate of primary outcome events compared to placebo, although it also carried a higher risk of hyperkalemia.

Background: Heart failure with mildly reduced or preserved ejection fraction (hereafter referred to as HFpEF) is the most common type of heart failure and is associated with a high risk of hospitalisation and death, especially in patients with overweight, obesity, or type 2 diabetes. In the STEP-HFpEF and STEP-HFpEF DM trials, semaglutide improved heart failure-related symptoms and physical limitations in participants with HFpEF. Whether semaglutide also reduces clinical heart failure events in this group remains to be established.
