    6. Early versus delayed treatment with ticagrelor on residual thrombus after percutaneous coronary intervention in patients presenting with non-ST-elevation acute coronary syndrome: an optical coherence tomography study

      Early versus delayed treatment with ticagrelor on residual thrombus after percutaneous coronary intervention in patients presenting with non-ST-elevation acute coronary syndrome: an optical coherence tomography study
      Ticagrelor, a P2Y12 antagonist, is well known for its rapid, high-potent inhibition of platelet aggregation by pharmacokinetic studies [ 1 ]. In the PLATO study, ticagrelor, compared to clopidogrel, reduced the incidence of myocardial infarction, stroke, cardiovascular death and definite stent thrombosis, during 12-month follow-up in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) [ 2 , 3 ]. To date, the effect of early ticagrelor administration versus treatment at the time ...

    7. Early versus delayed treatment with ticagrelor on residual thrombus after percutaneous coronary intervention in patients presenting with non-ST-elevation acute coronary syndrome an optical coherence tomography study

      Early versus delayed treatment with ticagrelor on residual thrombus after percutaneous coronary intervention in patients presenting with non-ST-elevation acute coronary syndrome an optical coherence tomography study
      Objective The level of inhibition of platelet aggregation immediately before percutaneous coronary intervention (PCI) is known to be related to early periprocedural outcomes. Ticagrelor is a reversible P2Y12 inhibitor that provides faster and more effective platelet inhibition compared to clopidogrel. This study sought to compare the antiplatelet effect on residual thrombus between early vs. delayed administration of ticagrelor following PCI in patients presenting with non-ST-elevation acute coronary syndromes (NSTE-ACS). Methods ...

    14. In vivo comparison of lumen dimensions measured by time domain-, and frequency domain-optical coherence tomography, and intravascular ultrasound

      In vivo comparison of lumen dimensions measured by time domain-, and frequency domain-optical coherence tomography, and intravascular ultrasound
      Lumen dimensions measured by time-domain optical coherence tomography (TD-OCT) may be influenced by the hemodynamic effect of proximal balloon occlusion. Frequency-domain OCT (FD-OCT) does not require the interruption of blood flow. Therefore, we compared the coronary lumen dimensions measured by TD-OCT, FD-OCT, and intravascular ultrasound (IVUS) in both stented and non-stented segments. Twenty patients who underwent both IVUS and OCT imaging (10 for TD- and 10 for FD-OCT) after stent ...
