Filter by:Optical coherence tomography (OCT) offers a high-resolution intravascular imaging modality to accurately assess vessel and lumen geometry and identify the hallmark of a culprit lesion including plaque disruption and thrombus. In addition, the incorporation of the MLD MAX algorithm into daily practice guides an efficient and easily-memorable workflow for optimized OCT-guided percutaneous coronary intervention (PCI) with drug-eluting stents (DES). Regarding the antithrombotic therapy after revascularization, the 2023 ESC guidelines recommend the P2Y12 receptor inhibitor de-escalation (i.e. switching from ticagrelor to clopidogrel) in ACS patients may be considered as an alternative strategy to the default treatment regimen in order to reduce the risk of bleeding events. Based on the above conclusions, we designed a single-center, prospective, randomized controlled, exploratory study trial to evaluate whether the utility of OCT for guiding PCI with DES followed by antiplatelet de-escalation therapy could further reduce the stent-induced intimal hyperplasia of STEMI patients after stent implantation.
The purpose of this study is (1) to determine whether 24-month dual antiplatelet therapy (DAPT) is superior to 12-month DAPT after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) with respect to major adverse cardiovascular and cerebrovascular events (all-cause death, myocardial infarction, or stroke) in patients with elevated lipoprotein(a)[Lp(a)] levels (>30mg/dL); (2) to determine whether 24-month DAPT is non-inferior to 12-month DAPT after PCI with DES with respect to net adverse clinical events (all-cause death, myocardial infarction, stroke or Bleeding Academic Research Consortium [BARC] type 3 or 5 bleeding) in patients with elevated Lp(a) levels (>30mg/dL).
to assess whether cessation of 12 months DAPT regimen containing Ticagrelor results in a hyperreactive phase of platelet function
