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.

Objective: Machine learning (ML) may allow for improved discernment of hemodynamics and oxygen delivery compared to standard invasive monitoring. We hypothesized that an ML algorithm could predict impaired delivery of oxygen (IDO) with comparable discrimination to invasive mixed venous oxygen saturation (SvO) measurement.

Methods: A total of 230 patients not on mechanical circulatory support (MCS) managed with a pulmonary artery catheter (PAC) were identified from 1012 patients admitted to a single cardiovascular intensive care unit (CVICU) between April 2021 and January 2022.

Background: Hypertension is common in patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), and current guidelines recommend treating systolic blood pressure (SBP) to a target <130 mm Hg. However, data supporting treatment to this target are limited. Additionally, pulse pressure (PP), a marker of aortic stiffness, has been associated with increased risk of cardiovascular events, but its prognostic impact in HFpEF has not been extensively studied.

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: GLP-1 receptor agonists reduce the risk of major adverse cardiovascular events (MACE) and can also have kidney benefits. However, whether GLP-1 receptor agonists improve clinically important kidney outcomes remains uncertain. We aimed to comprehensively assess the effects of GLP-1 receptor agonists on kidney and cardiovascular disease outcomes by performing a meta-analysis of randomised controlled trials.

Article Synopsis
  • Wearable accelerometers provide a way to continuously monitor physical activity in patients with heart failure, which could be useful for assessing treatment effects.
  • In the DETERMINE trials, a subgroup of patients wore accelerometers at different points while also completing questionnaires and walking tests to evaluate their functional status.
  • Results showed that lower activity levels were associated with worse health scores and measures, but overall, the relationships between accelerometer data and health assessments were generally weak, suggesting accelerometers could offer additional insights beyond traditional methods.

  • - Atrial fibrillation (AF) is more common in patients with type 2 diabetes and is linked to worse health outcomes; a trial called Harmony Outcomes was conducted to study the effects of albiglutide, a GLP-1 receptor agonist, on cardiovascular events in these patients.
  • - The trial included nearly 9,500 participants over 1.6 years and found that those with a history of AF had a higher rate of major adverse cardiac events, but albiglutide treatment reduced these events regardless of AF history.
  • - Although both groups on albiglutide experienced fewer AF events than those receiving a placebo, the reduction wasn't statistically significant, indicating that albiglutide can lower cardiovascular risks without

Article Synopsis
  • Lower eGFR might lead to reluctance in starting heart failure therapies, and the study examines how kidney function influences the effectiveness of sacubitril/valsartan compared to valsartan.
  • The PARAGON-HF trial included 4,796 chronic heart failure patients and found that those with lower baseline eGFR (<45 mL/min/1.73 m²) experienced a greater reduction in cardiovascular events when treated with sacubitril/valsartan.
  • The results suggest that sacubitril/valsartan is particularly beneficial for heart failure patients with preserved ejection fraction and lower eGFR, indicating the need for careful consideration when prescribing treatments in this population.

Background And Aims: Individuals with heart failure (HF), other forms of cardiovascular disease, or kidney disease are at increased risk for the development and adverse health effects of diabetes. As such, prevention or delay of diabetes is an important treatment priority in these groups. The aim of this meta-analysis was to determine the effect of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on incident diabetes in HF across the spectrum of left ventricular ejection fraction (LVEF) and across the broader spectrum of cardiovascular or kidney disease.

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.
