  Background and aims Accumulation of advanced glycation end products (AGEs) can be measured non-invasively by skin autofluorescence (SAF) whose values are elevated in patients with cardiovascular disease (CVD). Optical coherence tomography (OCT) is an intravascular imaging modality that could allow visualization of plaque composition. We aim to examine the relationship between SAF and plaque composition evaluated by frequency-domain OCT in patients with CVD. Methods We prospectively enrolled 108 patients with ...

  Recent studies revealing genetic connection of primary open angle glaucoma (POAG) and amyotrophic lateral sclerosis (ALS) have received particular attention. Exploring the evidence for common pathogenesis of these two progressive neurological disorders may assist in understanding the mechanism and searching for new treatment. Retinal nerve fiber layer (RNFL) defect and corresponding visual field (VF) impairment are well known neuropathy signs in glaucoma. In our study, thickness of certain retinal layer ...

4. Clinical study of optical coherence tomography in the diagnosis of peripheral pulmonary artery thrombus
  
  Explore ScienceDirect Nov 16 2017 Cardiology
  
  Background Peripheral pulmonary artery thrombus (PPT) is common in the clinic. However, due to the lack of an ideal diagnostic tool, PPT cannot be quickly diagnosed and effectively treated at present. Optical coherence tomography (OCT) is a new intravascular imaging technique that is characterized by high image resolution. This technique is suitable for small vessel imaging and has the ability to distinguish red and white thrombi. Objective This study aimed ...

  Objectives The aim of the present study was to evaluate vascular healing of the bioengineered COMBO Dual Therapy Stent compared with a cobalt-chromium (CoCr) everolimus-eluting stent (EES) as assessed by optical coherence tomography in patients with acute coronary syndromes. Background CD34+ cells promote endothelial repair after vascular injury. The bioengineered COMBO Dual Therapy Stent combines CD34+ cellcapturing technology with abluminal sirolimus release, but more data from clinical studies evaluating the ...

  Purpose To evaluate retinal segmented layer alterations in optic neuritis (ON) in an AQP4-Ab seropositive (AQP4-Ab+/ON) cohort and in neuromyelitis optica (NMO) with ON eyes (NMO-ON) compared with an AQP4-Ab seronegative ON (AQP4-Ab/ON) cohort using optical coherence tomography (OCT). Methods We recruited 109 patients with ON (161 eyes) and 47 healthy controls. All patients with ON were subdivided into three subcohorts: 37 patients (54 eyes) with AQP4-Ab+/ON ...

8. Difference in Vascular Response between Sirolimus-eluting- and Everolimus-eluting Stents in Ostial Left Circumflex Artery after Unprotected Left Main as Observed by
  
  Explore Elsevier Health Dec 23 2016 Cardiology
  
  Background Kissing-balloon technique (KBT) is commonly performed during percutaneous coronary intervention of distal unprotected left main coronary artery (ULM) aiming at obtaining optimal opening of the side branch (left circumflex artery; LCX) ostium. Nonetheless, detailed evaluation of vascular response to stents in LCX ostium is lacking. We therefore evaluated the vascular response to different drug-eluting stents (DES) in ostial LCX after ULM by means of optical coherence tomography (OCT). Methods ...

  Background Coronary angiography (CAG) is widely used to assess lumen dimensions, and optical coherence tomography (OCT) is used to evaluate the characteristics of atherosclerotic plaque. This study was aimed to compare coronary lumen dimensions using CAG and plaque characteristics using OCT and their changes during statin therapy. Methods We identified 97 lipid-rich plaques from 69 statin-nave patients, who received statin therapy in the following 12 months. CAG and OCT examinations ...

  Background There are few clinical studies on the pathophysiological mechanisms of very late stent thrombosis (VLST). We report optical coherence tomography findings in patients with VLST and compare the findings between bare-metal stents (BMS) and drug-eluting stents (DES). Methods and Results We conducted a registry of stent thrombosis at 4 North American centers with optical coherence tomography imaging programs SAFE registry (The Study of Late Stent Failure Evaluated by OCT ...

11. Measuring Airway Remodeling in Patients with Different COPD Staging Using Endobronchial Optical Coherence Tomography
  
  Explore ScienceDirect Aug 16 2016 Pulmonology
  
  Background Although forced expiratory volume in one second (FEV 1 ) remains the gold standard for staging COPD, the association between airway remodeling and airflow limitation remains unclear. Objective Endobronchial optical coherence tomography (EB-OCT) was performed to assess the association between disorders of large- and medium-to-small-sized airways and COPD staging. We also evaluated small-airway architecture in heavy-smokers with normal FEV 1 (S NL ) and healthy never-smokers. Methods We recruited 48 COPD ...
