6. Clinical Significance of Lipid-Rich Plaque Detected by Optical Coherence Tomography : A 4-Year Follow-Up Study
  
  Explore ScienceDirect May 29 2017 Cardiology
  
  Background Lipid-rich plaque (LRP) is thought to be a precursor to cardiac events. However, its clinical significance in coronary arteries has never been systematically investigated. Objectives This study investigated the prevalence and clinical significance of LRP in the nonculprit region of the target vessel in patients undergoing percutaneous coronary intervention (PCI). Methods The study included 1,474 patients from 20 sites across 6 countries undergoing PCI, who had optical coherence ...

8. Characteristics of Earlier Versus Delayed Presentation of Very Late Drug‐Eluting Stent Thrombosis: An Optical Coherence Tomographic Study
  
  Explore jaha.ahajournals.org Apr 18 2017 Cardiology
  
  Background The pathophysiology underlying very late drug‐eluting stent ( DES ) thrombosis is not sufficiently understood. Using optical coherence tomography, we investigated characteristics of very late stent thrombosis ( VLST ) according to different onset times. Methods and Results A total of 98 patients from 10 South Korean hospitals who underwent optical coherence tomography for evaluation of very late DES thrombosis were retrospectively included in analyses. VLST occurred at a median of 55 ...

9. Coronary Plaque Characteristics Associated With Reduced TIMI (Thrombolysis in Myocardial Infarction) Flow Grade in Patients With ST-Segment–Elevation Myocardial Infarction A Combined Optical Coherence Tomography and Intravascular Ultrasound Study
  
  Explore Circulation Sep 14 2016 Cardiology
  
  Background Previous studies reported that reduced TIMI (Thrombolysis in Myocardial Infarction) flow grade before procedure was associated with worse clinical outcomes in patients with ST-segmentelevation myocardial infarction undergoing primary percutaneous coronary intervention. The aim of this study was to identify specific morphological characteristics of the culprit plaque associated with poor TIMI flow grade at baseline in patients with ST-segmentelevation myocardial infarction using both optical coherence tomography and intravascular ultrasound. Methods ...

  Objectives: This study sought to explore the association between the Framingham Risk Score (FRS) and coronary plaque characteristics assessed by optical coherence tomography (OCT) imaging. Background: Clinical prediction models are useful for identifying high-risk patients. However, coronary events often occur in individuals estimated to be at low risk. Methods: A total of 254 patients with coronary artery disease who underwent three-vessel OCT were divided into tertiles according to FRS. Nonculprit ...

15. Coronary Calcification and Plaque Vulnerability An Optical Coherence Tomographic Study
  
  Explore Circulation Jan 12 2016 Cardiology
  
  Background Spotty superficial calcium deposits have been implicated in plaque vulnerability based on previous intravascular imaging studies. Biomechanical models suggest that microcalcifications between 5 and 65 m in diameter can intensify fibrous cap stress, promoting plaque rupture. However, the 100- to 200-m resolution of intravascular ultrasound limits its ability to discriminate single calcium deposits from clusters of smaller deposits, and a previous optical coherence tomographic investigation evaluated calcifications within a ...
