Article Synopsis
  • Non-vitamin-K oral anticoagulants like Edoxaban are effective for preventing strokes in patients with atrial fibrillation (AF), but there's limited data on their long-term outcomes in routine care in Germany, Austria, and Switzerland (DACH).
  • The ETNA-AF-Europe study enrolled 13,092 AF patients across 10 European countries, with 5,457 patients from the DACH region, revealing that the majority received appropriate Edoxaban dosing.
  • After one year, the study found low rates of stroke (0.8%/year) and severe bleeding (0.7%/year), but higher age and frailty were linked to increased mortality and complications.

As higher-valent pneumococcal conjugate vaccines (PCVs) become available for pediatric populations in the US, it is important to understand healthcare provider (HCP) preferences for and acceptability of PCVs. US HCPs (pediatricians, family medicine physicians and advanced practitioners) completed an online, cross-sectional survey between March and April 2023. HCPs were eligible if they recommended or prescribed vaccines to children age <24 months, spent ≥25% of their time in direct patient care, and had ≥2 y of experience in their profession.

Aims: Patients with atrial fibrillation (AF) treated with oral anticoagulation still suffer from cardiovascular complications including cardiovascular death, stroke, and major bleeding. To identify risk factors for predicting stroke and bleeding outcomes in anticoagulated patients, we assessed 2-year outcomes in patients with AF treated with edoxaban in routine care. We also report the age-adjusted risk predictors of clinical outcomes.

Background: Neurotensin is involved in fatty acid and glucose metabolism and promotes the development of obesity and diabetes. These associations appear to be more pronounced in women. We investigated the association of neurotensin with long-term major adverse cardiovascular events (MACE) in patients presenting with acute coronary syndrome (ACS) or chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI).

Article Synopsis
  • Coronary artery aneurysms (CAA) occur in about 5% of patients during coronary angiography, and while covered stents have been used for treatment, there’s limited evidence on their effectiveness and safety.
  • A systematic review of 63 case reports and 3 case series included data from 81 patients, revealing a high procedural success rate of 95.1%, with the majority of aneurysms located in native coronary arteries.
  • Although the use of covered stents appears generally effective and reasonably safe, there is a notable 26.2% rate of major adverse cardiovascular events, primarily due to increased target lesion revascularization, highlighting a need for further research to optimize patient selection for this treatment.

Article Synopsis
  • Study investigates the roles of von Willebrand factor (VWF) and its cleaver, ADAMTS13, in predicting major adverse cardiovascular outcomes (MACE) in patients undergoing percutaneous coronary intervention (PCI).
  • Analyzed data from 701 patients, finding that VWF levels were linked to higher MACE and mortality in those with acute coronary syndrome (ACS), but not in stable coronary artery disease (SCAD).
  • The study concludes that VWF is a critical risk marker for ACS, while ADAMTS13 shows no predictive value for MACE or mortality in either ACS or SCAD.

Background: Increased platelet turnover and high platelet reactivity are associated with short-term major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) or stable coronary artery disease (SCAD). We investigated the impact of platelet turnover on long-term MACE.

Methods: Consecutive patients presenting with ACS or SCAD undergoing PCI between 2009 and 2010 were included.

Article Synopsis
  • Non-vitamin K antagonist oral anticoagulants (NOACs), like edoxaban, have improved stroke prevention in atrial fibrillation patients, but detailed safety data on edoxaban is limited.
  • The ETNA-AF-Europe study included 13,638 patients with a mean age of 73.6 years, mostly male, and assessed their baseline characteristics and risk scores for stroke.
  • A significant percentage (75.1%) started edoxaban as their first anticoagulant, showing good adherence to dosing guidelines, with many patients categorized as high-risk for stroke.

Article Synopsis
  • - The study focused on soluble P-selectin (sP-selectin), a biomarker linked to inflammation and cardiovascular issues, particularly its role in promoting atherosclerosis and recruiting immune cells, and evaluated its effect on long-term major adverse cardiovascular events (MACE) after coronary stenting.
  • - Researchers analyzed data from 733 patients who underwent coronary interventions from 2003 to 2006, measuring sP-selectin levels and categorizing patients into quartiles. They tracked occurrences of all-cause death, myocardial infarction (MI), and stroke over an average follow-up of 9.7 years.
  • - Results showed that higher sP-selectin levels correlated with increased risk of MACE, with 46.9%

Long-term evidence shows an increased risk of cardiovascular events in the morning hours and recent studies in aspirin-treated patients have shown increased platelet reactivity at the end of the dosing interval. Similar pharmacodynamic analyses of adenosine-diphosphate (ADP) receptor inhibitors are scarce. We therefore investigated changes in clopidogrel-dependent platelet function and activation over 24 h and whether enhanced platelet turnover might explain diurnal variability of platelet function and activation.
