    2. Impact of hemodialysis on clinical and angiographic outcomes in in-stent restenotic lesions following optical coherence tomography-guided drug-coated balloon treatment

      Impact of hemodialysis on clinical and angiographic outcomes in in-stent restenotic lesions following optical coherence tomography-guided drug-coated balloon treatment
      Hemodialysis (HD) is associated with a high in-stent restenosis (ISR) rate even in the second-generation era. Drug-coated balloons (DCB) generally provide excellent clinical outcomes in patients with ISR lesions. Nonetheless, safety and efficacy of DCB for ISR lesions in HD patients are largely unknown. A total of 17 centers across Japan participated in this study. Patients were eligible for the study if ISR lesions were treated with DCB. Enrolled patients ...

    3. Predictors of Rapid Plaque Progression: An Optical Coherence Tomography Study

      Predictors of Rapid Plaque Progression: An Optical Coherence Tomography Study
      Objectives This study sought to identify morphological predictors of rapid plaque progression. Background Two patterns of plaque progression have been described: slow linear progression and rapid step-wise progression. The former pattern will cause stable angina when the narrowing reaches a critical threshold, whereas the latter pattern may lead to acute coronary syndromes or sudden cardiac death. Methods Patients who underwent optical coherence tomography (OCT) imaging during the index procedure and ...

      Spatial Distribution of Vulnerable Plaques: Comprehensive In Vivo Coronary Plaque Mapping
      Objectives The authors performed a comprehensive analysis on the distribution of coronary plaques with different phenotypes from our 3-vessel optical coherence tomography (OCT) database. Background Previous pathology studies demonstrated that thin-cap fibroatheroma (TCFA) is localized in specific segments of the epicardial coronary arteries.

    5. Circadian variations in pathogenesis of ST-segment elevation myocardial infarction: an optical coherence tomography study

      Circadian variations in pathogenesis of ST-segment elevation myocardial infarction: an optical coherence tomography study
      Previous studies have reported a circadian variation in the onset of ST-segment elevation myocardial infarction (STEMI). However, underlying mechanisms for the circadian variation have not been fully elucidated. We investigated the relationship between onset of STEMI and the underlying pathology using optical coherence tomography (OCT). Patients with a diagnosis of STEMI were selected from a multicenter OCT registry. Patients were divided into 4 groups based on the estimated time of ...

    6. Predictors for layered coronary plaques: an optical coherence tomography study

      Predictors for layered coronary plaques: an optical coherence tomography study
      Healed coronary plaques, morphologically characterized by a layered pattern, are signatures of previous plaque disruption and healing. Recent optical coherence tomography (OCT) studies showed that layered plaque is associated with vascular vulnerability. However, factors associated with layered plaques have not been studied. The aim of this study was to investigate predictors for layered plaque at the culprit plaques and at non-culprit plaques. Patients with coronary artery disease who underwent pre-intervention ...

    7. Endothelial glycocalyx and severity and vulnerability of coronary plaque in patients with coronary artery disease

      Endothelial glycocalyx and severity and vulnerability of coronary plaque in patients with coronary artery disease
      Background and aims Endothelial glycocalyx covers the endothelium and maintains vascular integrity. However, its association with the severity and vulnerability of coronary artery disease (CAD) remains to be elucidated. Methods A total of 259 consecutive patients with stable CAD requiring percutaneous coronary intervention (PCI) were prospectively enrolled. Patients were classified into 2 groups according to the median value of serum syndecan-1, which is a core component of the endothelial glycocalyx ...

      Objectives To assess the clinical significance of a novel optical coherence tomography (OCT)‐derived volumetric parameter of stent expansion by comparing it with the conventional parameters in real‐world practice. Background The clinical significance of novel parameters in real‐world practice including longer and smaller stents remains to be elucidated. Methods A total of 226 de novo lesion treated with drug‐eluting stents in 208 consecutive patients were enrolled. Stent ...

      Comparison of post‐stent optical coherence tomography findings among three subtypes of calcified culprit plaques in patients with acute coronary syndrome
      Objectives To compare the postprocedural optical coherence tomography (OCT) findings and in‐hospital outcomes among the three subtypes of calcified plaques: eruptive calcified nodules, superficial calcific sheet, and calcified protrusion. Background Recently, three subtypes of calcified culprit plaques were reported in patients with acute coronary syndrome (ACS). How these subtypes respond to stenting is unknown. Methods ACS patients with calcified plaque at the culprit lesion were selected from our database ...

However, the association between serum Lp(a) level and coronary plaque vulnerability remains to be determined. Methods A total of 255 consecutive patients with CAD who underwent optical coherence tomography imaging of culprit lesions were included. Patients were divided into 2 groups according to their Lp(a) levels (the ...
