Background And Aims: Based on retrospective studies, the 2022 European guidelines changed the definition of post-capillary pulmonary hypertension (pcPH) in heart failure (HF) by lowering the level of mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR). However, the impact of this definition and its prognostic value has never been evaluated prospectively.

Methods: Stable left HF patients with the need for right heart catheterization were enrolled from 2010 to 2018 and prospectively followed up in this multicentre study.

Pulmonary hypertension (PH) continues to present significant challenges to the medical community, both in terms of diagnosis and treatment. The advent of the updated 2022 European Society of Cardiology (ESC) and European Respiratory Society (ERS) guidelines has introduced pivotal changes that reflect the rapidly advancing understanding of this complex disease. These changes include a revised definition of PH, updates to the classification system, and treatment algorithm.

Article Synopsis
  • The study investigates the use of salt substitutes (saltSubs) for managing sodium intake in patients with chronic heart failure (CHF) in France, focusing on healthcare professional (HCP) recommendations and patient consumption.
  • Only 13% of HCPs recommended saltSubs, while 17% of patients and 22% of caregivers reported using them, with those recommended showing a recent hospitalization for acute heart failure.
  • The findings revealed that patients advised to use saltSubs were less likely to follow guideline-directed medical therapies (GDMTs), particularly angiotensin-converting enzyme inhibitors and related medications, indicating a potential conflict between saltSubs and standard CHF treatments.

Article Synopsis
  • * In a study involving 772 patients with cardiogenic shock, 21.3% had CKD, and these patients were generally older and had more health issues, which contributed to increased mortality.
  • * Renal replacement therapy (RRT) was associated with a higher risk of death regardless of CKD status, highlighting the need for collaborative care between cardiac and kidney specialists to better manage these patients.

Background: Cardiogenic shock (CS) is the most severe form of acute heart failure. Discrepancies have been reported between sexes regarding delays, pathways and invasive strategies in CS complicating acute myocardial infarction. However, effect of sex on the prognosis of unselected CS remains controversial.

Article Synopsis
  • The study evaluated the prognostic significance of non-invasive parameters related to ventricular-arterial coupling (VAC) in patients with left ventricular ejection fraction (LVEF) ≥40% after a myocardial infarction (MI).
  • Using echocardiography and arterial tonometry, researchers measured VAC parameters during rest and a handgrip test in 374 patients, tracking major adverse cardiovascular events (MACE) over a median of 32 months.
  • Results indicated that the PWV/GLS ratio was the most useful parameter for identifying high-risk patients for MACE after MI, suggesting it adds valuable information beyond traditional assessment methods.

Article Synopsis
  • - The beta-adrenergic signaling pathway is crucial in managing heart failure (HF), with beta-blockers (BBs) being the first-line treatment for patients with HF and reduced ejection fraction (HFrEF).
  • - In cases of severe acute heart failure (AHF), particularly those recovering from cardiogenic shock, starting BB therapy can be risky due to a lack of comprehensive data.
  • - An expert consensus has been developed to review existing studies on BB use in severe decompensated AHF and offers a practical algorithm for prescribing and monitoring BB therapy in critical conditions.

Article Synopsis
  • The study examines heart failure and cardiogenic shock (CS) in older adults, highlighting that the incidence is rising due to an aging population, with limited data available on this demographic.
  • The research involved a registry called FRENSHOCK, which included 772 CS patients, revealing that 30.6% were over 75 years old, with higher comorbidities and lower treatment intensity compared to younger patients.
  • Results indicated that older adults have more than double the risk of death at 1 month and 1 year post-CS, emphasizing the need for targeted research to determine effective treatment strategies for this age group.

  • Cardiogenic shock is a rare condition in adults with congenital heart disease (ACHD), making up only 0.9% of cases in a nationwide registry study in France.
  • The study found that ACHD patients were younger and had fewer risk factors for cardiovascular issues compared to non-ACHD patients, but they still experienced a high rate of severe outcomes after one year, similar to non-ACHD patients.
  • Management strategies differed significantly, with ACHD patients more likely to receive catheterizations and device implantations while less likely to use temporary circulatory support or invasive ventilation.

  • This study explored the characteristics, management, and outcomes of patients with active cancer who were admitted for cardiogenic shock, finding that they made up about 6.6% of the 772 enrolled patients.
  • Although active cancer patients had similar initial in-hospital outcomes as non-cancer patients, they required more intensive drug management but received less mechanical support.
  • While both groups had similar 30-day mortality rates, the active cancer group had significantly higher long-term mortality rates at 1 year, indicating that active cancer dramatically impacts survival after initial treatment for cardiogenic shock.
