Article Synopsis
  • Renal dysfunction is common in heart failure patients and linked to poor outcomes, but how cardiac structure and function impact kidney health remains unclear.
  • This study analyzed data from the PARAGON-HF trial to explore the relationship between echocardiographic measurements of heart structure/function and changes in kidney function over time.
  • Results showed that higher left ventricular mass and certain heart parameters are associated with greater declines in kidney function and an increased risk of serious kidney-related events, suggesting that cardiac health plays a crucial role in renal outcomes for these patients.

Article Synopsis
  • The study aims to understand heart failure (HF) characteristics and outcomes specifically in octogenarians (people aged 80 and older), as this age group is often underrepresented in research despite higher HF prevalence.
  • Analysis of data from eight randomized trials revealed that octogenarians with different types of HF (HFrEF, HFmrEF, HFpEF) tended to be more female and had more health complications, worse health status, and higher rates of hospitalization and mortality compared to younger patients.
  • The findings indicate that octogenarians receive less treatment based on guidelines, particularly certain medications, despite their poorer health and worse outcomes, suggesting a need for better management in this age group.

Article Synopsis
  • Ferric carboxymaltose (FCM) is used for treating iron deficiency in patients with heart failure, but its effects on phosphate levels are not fully understood.
  • This study involved a trial comparing the effects of FCM to a placebo on serum phosphate and hormone levels in patients over six months, finding significant decreases in phosphate in those receiving FCM.
  • Although moderate-to-severe hypophosphataemia occurred in some patients, no serious side effects were reported, and biochemical changes generally returned to baseline after three months.

As a result of the widespread use of reperfusion therapies and secondary prevention over the last 30 years, there has been a dramatic reduction in the risk of mortality and development of heart failure (HF) following acute myocardial infarction (MI). Despite this, the development of chronic HF remains a common occurrence in the days, months, and years following MI. Neurohormonal inhibition remains the mainstay of pharmacologic prevention of HF following MI, with recent trials showing an additive benefit of a neprilysin inhibitor or a sodium glucose co-transporter 2 inhibitor in reducing the risk of development of HF but no significant effect on mortality.

Article Synopsis
  • The 2022 Canadian Cardiovascular Society guidelines recommend the use of sodium-glucose co-transport 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) for improving cardiorenal health, particularly as new relevant trials emerge.
  • An updated review of randomized controlled trials from September 2021 to April 2023 included 151,023 adult participants, comparing the effectiveness of SGLT2i and GLP-1RA against standard care in reducing cardiovascular and kidney-related health issues.
  • The analysis found that both SGLT2i and GLP-1RA significantly lower risks for various outcomes related to heart health and mortality, with specific advantages

Background: Inflammation plays a central role in the genesis and progression of heart failure with preserved ejection fraction (HFpEF). C-reactive protein (CRP) is widely used as means to assess systemic inflammation, and elevated levels of CRP have been associated with poor HF prognosis. Identification of chronic low-grade inflammation in outpatients can be performed measuring high-sensitivity CRP (hsCRP).

Background: While significant gains were made in the management of heart failure (HF), most patients are still diagnosed when they are acutely ill in hospital, often with advanced disease. Earlier diagnosis in the community could lead to improved outcomes. Whether a partnership and an educational program for primary care providers (PCP) increase HF awareness and management is unknown.

Background: Clinical trials in heart failure (HF) traditionally use time-to-event analyses focusing on death and hospitalization for HF. These time-to-first event analyses may have more limited abilities to assess the probability of benefiting from a therapy, especially if that benefit manifests as improved functional status rather than reduced risk of death or HF hospitalization. Hierarchical end points including clinical outcomes and patient status measures allow for ranked evaluation of outcomes in 1 metric assessing whether patients randomized to intervention or control are more likely to derive an overall benefit while also allowing more patients to contribute to the primary outcome.

Background: Women with heart failure with reduced ejection fraction (HFrEF) receive less guideline-recommended therapy and experience worse quality of life than men.

Objectives: The authors sought to assess differences in baseline characteristics, outcomes, efficacy, and safety of omecamtiv mecarbil between men and women enrolled in the GALACTIC-HF (Registrational Study With Omecamtiv Mecarbil [AMG 423] to Treat Chronic Heart Failure With Reduced Ejection Fraction) study.

Methods: In GALACTIC-HF, patients with symptomatic heart failure with EF of 35% or less, recent heart failure event, and elevated natriuretic peptides were randomized to omecamtiv mecarbil or placebo.

Background: Ferric carboxymaltose therapy reduces symptoms and improves quality of life in patients who have heart failure with a reduced ejection fraction and iron deficiency. Additional evidence about the effects of ferric carboxymaltose on clinical events is needed.

Methods: In this double-blind, randomized trial, we assigned ambulatory patients with heart failure, a left ventricular ejection fraction of 40% or less, and iron deficiency, in a 1:1 ratio, to receive intravenous ferric carboxymaltose or placebo, in addition to standard therapy for heart failure.

The presence of a systemic right ventricle (sRV) with biventricular physiology (biV) is associated with increased patient morbidity and mortality. To date, no pharmacologic therapy for heart failure has been proven effective for patients with systolic dysfunction of the sRV-biV. We designed a randomized, double-blind, placebo-controlled crossover trial to compare sacubitril/valsartan treatment to placebo in adults (aged ≥ 18 years) with moderate-to-severe sRV-biV dysfunction and New York Heart Association functional class II to III symptoms.

Article Synopsis
  • - Elevated levels of CA125 are linked to increased risk of worsening heart failure (HF) or cardiovascular death in patients with chronic ambulatory HF with reduced ejection fraction, as demonstrated in the DAPA-HF trial.
  • - In the study, patients with CA125 levels above 35 U/mL showed a significantly higher risk for adverse outcomes compared to those with lower levels, suggesting CA125 is a useful marker for predicting patient prognosis.
  • - The heart failure medication dapagliflozin showed consistent benefits in reducing the risk of worsening HF or cardiovascular death, regardless of initial CA125 levels, highlighting its effectiveness across different patient profiles.

A number of societies produce heart failure (HF) management guidelines, comprising official recommendations on the basis of recent research discoveries, but their applicability to specific situations encountered in daily practice might be difficult. In this clinical practice update we aim to provide responses to fundamental questions that face health care providers, like appropriate timing for the introduction and optimization of different classes of medication according to specific patient phenotypes, when second-line therapies and valvular interventions should be considered, and management of difficult clinical scenarios such as cardiorenal syndrome and frailty. A consensus-based methodology was used.

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]).

With modern treatments for heart failure with reduced ejection fraction (EF), indicative of impaired cardiac systolic function, patients may exhibit an increase in EF. Limited data are available regarding the clinical management of this growing population, categorized as heart failure with improved EF (HFimpEF), which has a high event rate and has been excluded from virtually all prior heart failure outcomes trials. In a prespecified analysis of the DELIVER trial ( NCT03619213 ), of a total of 6,263 participants with symptomatic heart failure and a left ventricular EF >40%, 1,151 (18%) had HFimpEF, defined as patients whose EF improved from ≤40% to >40%.

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.
