Background And Aims: Heart failure (HF) is an imminent global health problem. Yet established screening algorithms for asymptomatic pre-HF, allowing for early and effective preventive interventions, are largely lacking. The HERZCHECK trial, conducted in structurally underserved rural regions of North-Eastern Germany, aims to close this gap by evaluating the feasibility, diagnostic efficacy, and cost-effectiveness of a fully mobile, telemedically-supervised screening approach, combining cardiac magnetic resonance imaging (CMR) and laboratory testing as central elements.

Introduction: Out-of-hospital cardiac arrest (OHCA) is a critical condition associated with high mortality rates and neurological impairment among survivors. In comatose OHCA patients who achieve return of spontaneous circulation, early risk stratification is important to inform treatment pathways and potentially improve outcomes. A range of prognostic tools have been developed to predict survival and neurological recovery.

Article Synopsis
  • Many patients with atrial fibrillation (AF) are not receiving or are stopping oral anticoagulation therapy, despite its importance for stroke prevention.
  • While direct oral anticoagulants (DOACs) are available, issues like bleeding risks, poor compliance, and aversion to treatment contribute to this problem.
  • A recent expert consensus guide highlights left atrial appendage closure (LAAC) as a safe alternative for stroke prevention in patients who cannot use long-term anticoagulation, detailing the devices, implantation technique, and follow-up requirements for non-implanting physicians.

Article Synopsis
  • Traditional cardiovascular biomarkers like hsTnT and NT-proBNP are crucial for monitoring cardiac function and prognosis in cancer patients, but newer biomarkers such as MR-proADM, copeptin, and MR-proANP may provide better predictive power.
  • A study involving 442 hospitalized cancer patients showed that while several biomarkers predicted all-cause mortality, only MR-proADM remained a significant independent predictor after adjusting for various factors.
  • MR-proADM demonstrated the highest predictive accuracy, with a specific cutoff of 0.94 nmol/L signaling a higher risk of mortality, particularly in older patients with advanced cancer stages and poorer overall health.

Background: Fractional flow reserve (FFR) or non-hyperaemic pressure ratios are recommended to assess functional relevance of intermediate coronary stenosis. Both diagnostic methods require the placement of a pressure wire in the coronary artery during invasive coronary angiography. Quantitative flow ratio (QFR) is an angiography-based computational method for the estimation of FFR that does not require the use of pressure wires.

Aim: Extracorporeal cardiopulmonary resuscitation (ECPR) by veno-arterial extracorporeal membrane oxygenation (VA-ECMO) during refractory cardiac arrest presents significant medical and psychological challenges for healthcare providers. Beyond managing cardiac arrest and preparing for potential coronary angiography, the ECMO circuit must be assembled and primed under strictly sterile conditions, contributing to additional psychological stress and potential delays in ECMO cannulation. This pragmatic study thought to evaluate whether pre-assembled and pre-primed ECMO circuits (pre-primed group) maintain sterility over a 21-day period, expedite ECMO initiation in ECPR patients and alleviate the psychological burden on the ECPR team, compared to newly assembled and primed ECMO circuits (on-demand group).

The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro-inflammatory and immune-modulating components, which complicates the identification of specific immune pathways suitable for therapeutic targeting.

Article Synopsis
  • Chronic total occlusions (CTOs) are a significant challenge in coronary artery disease (CAD) and require advanced diagnostic and treatment methods due to their prevalence in patients undergoing coronary angiography.
  • Traditional coronary angiography has limited ability to provide details on lesions and heart viability, but imaging techniques like optical coherence tomography (OCT), intravascular ultrasound (IVUS), and coronary computed tomography angiography (CCTA) offer valuable insights during percutaneous coronary intervention (PCI).
  • Although each imaging method has its drawbacks, they collectively improve CTO-PCI success rates, lower complications, and enhance patient outcomes, with future advancements such as AI and hybrid imaging expected to further improve precision and personalize patient care.
