      EROSION Study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion)
      Background The initial EROSION study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence TomographyBased Management in Plaque Erosion) demonstrated that patients with acute coronary syndrome caused by plaque erosion might be stabilized with aspirin and ticagrelor without stenting for 1 month. However, a long-term evaluation of outcomes is lacking. The aim of this study was to assess whether the initial benefit of noninterventional therapy for patients with acute coronary syndrome ...

    8. Impact of Cigarette Smoking and Smoking Cessation on Stent Changes as Determined by Optical Coherence Tomography after Sirolimus Stent Implantation

      Impact of Cigarette Smoking and Smoking Cessation on Stent Changes as Determined by Optical Coherence Tomography after Sirolimus Stent Implantation
      There is debate regarding whether smoking results in microstructural changes after stenting. The aim of this study was to evaluate the microstructural changes after stenting in patients with different smoking statuses. We retrospectively identified 220 sirolimus-eluting stents in 179 patients who underwent follow-up optical coherence tomography examination 12 months after sirolimus stenting. Subjects were classified as current smokers (CS, n=31), smoking cessation 1 year (SC1Y, n=36), smoking cessation ...

      Association of Platelet to lymphocyte ratio with non-culprit atherosclerotic plaque vulnerability in patients with acute coronary syndrome: an optical coherence tomography study
      Background The platelet to lymphocyte ratio (PLR), an indirect inflammatory biomarker, has been recently demonstrated to be associated with severity of coronary artery disease. In the present study, we sought to investigate whether PLR is associated with vulnerable plaque characteristics of non-culprit lesions in patients with acute coronary syndrome (ACS). Methods The patients in our study were divided into two groups (high PLR group and low PLR group). A total ...

    10. Role of Optical Coherence Tomography in Diagnosis and Treatment of Patients with Acute Coronary Syndrome

      Role of Optical Coherence Tomography in Diagnosis and Treatment of Patients with Acute Coronary Syndrome
      Acute coronary syndrome (ACS) is the main cause of death worldwide and the leading cause of disease burden in high-income countries. ACS refers to a constellation of clinical symptoms that are compatible with acute myocardial ischemia. It describes a spectrum of clinical manifestations that result from a common pathophysiological process. The most common cause of ACS are rupture of an atherosclerotic lesion containing a large necrotic core and a thin ...

      Relation Between Superficial Calcifications and Plaque Rupture: An Optical Coherence Tomography Study
      Background There are several forms of calcium deposition, which play different roles in the stability of the coronary artery. It remains unknown whether certain calcification morphological characteristics determine rupture of lipid-rich lesions in the same plaque in acute coronary syndrome (ACS). Methods We retrospectively analyzed 550 patients with ACS between May 2008 and October 2014, who had undergone pre-intervention optical coherence tomography (OCT) imaging examination. A total of 78 patients ...
