While timely blood transfusion is critical for restoring oxygen-carrying capacity after coronary artery bypass grafting (CABG), allogeneic blood product transfusions are independently associated with increased long-term mortality, necessitating a risk-stratified approach to balance oxygen delivery against immunological complications and infection risks. We retrospectively analyzed 3376 patients undergoing isolated CABG between 2005 and 2023 at a single tertiary center. Patients who died during their perioperative hospital stay within 30 days were excluded.

Whether culotte or double kissing (DK)-crush stenting is the superior systematic 2-stent technique in non-left main bifurcation lesions is unclear. The BBK-3 (unique identifier NCT04192760) is a multicenter, prospective, randomized controlled trial to test the hypothesis that culotte stenting reduces maximal percent diameter restenosis at 9-month follow-up compared to DK-crush stenting in de-novo non-left main coronary bifurcation lesions using approved, third-generation drug-eluting stents (DES). A total of 400 patients will be randomized in a 1:1 ratio to receive a two-stent strategy.

: For patients with percutaneous coronary intervention (PCI) of an unprotected left main coronary artery (uLMCA) stenosis, the optimal duration of dual antiplatelet therapy (DAPT) remains a matter of debate. The purpose of this study was to compare clinical outcomes of 6- versus 12-month DAPT duration in patients with PCI of an uLMCA and stable angina. : In this retrospective analysis, we included consecutive patients of our centre who underwent PCI of uLMCA stenosis for stable angina and who received DAPT with acetylsalicylic acid and clopidogrel for either 6 or 12 months.

Background High-sensitivity cardiac troponin (hs-cTn)-based diagnostic algorithms are recommended for the management of patients with suspected myocardial infarction (MI) without ST elevation. Although mirroring different phases of myocardial injury, falling and rising troponin patterns (FPs and RPs, respectively) are equally considered by most algorithms. We aimed to compare the performance of diagnostic protocols for RPs and FPs, separately.

Background: After an acute myocardial infarction (MI), repeated measurement of cardiac biomarkers is commonly performed, although not recommended in current guidelines. There is only limited data on the kinetics of troponin in this phase. For high-sensitivity cardiac troponin T (hs-cTnT), but not high-sensitivity cardiac troponin I (hs-cTnI), late increases in terms of a second peak have been described.

Article Synopsis
  • Researchers tested a machine learning-based multibiomarker panel to predict major adverse cardiovascular events (MACE) in patients with suspected myocardial infarction (MI).
  • The study involved 748 patients, assessing a prognostic panel made up of four biomarkers, with a focus on MACE occurrence within one year.
  • The model showed a high predictive ability with an area under the curve of 0.86 and a 99.4% negative predictive value at the optimal cut-off, indicating that a high prognostic score correlates with an increased risk for MACE.
