      Lipoprotein (a) level is associated with plaque vulnerability in patients with coronary artery disease: An optical coherence tomography study
      Background High lipoprotein (a) [Lp(a)] levels are an independent factor for worse prognosis in patients with coronary artery disease (CAD). 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 ...

      Zero-Contrast Optical Coherence Tomography- and Physiology-Guided Percutaneous Coronary Intervention for Severely Calcified Lesion
      An 80-year-old man with severe kidney dysfunction (estimated glomerular filtration rate, 26 mL/min/1.73 m 2 ) not requiring hemodialysis presented with effort angina. Diagnostic angiography with minimum contrast showed a diffuse lesion in the proximal right coronary artery (RCA; Figure A ). On a later day, optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) with dextran injection was performed. Because multiple cracks were seen in the severely calcified ...

      Impact of underlying plaque type on strut coverage in the early phase after drug-eluting stent implantation
      Background The aim of this study was to investigate whether the underlying plaque type affects the neointimal coverage after drug-eluting stent implantation. Methods A total of 1793 struts in 22 zotarolimus-eluting stents were assessed using optical coherence tomography imaging within 3 months of implantation. Neointimal coverage was evaluated within 5mm from each stent edge on cross-sectional optical coherence tomography images at every 1-mm interval. The percentage of struts covered by ...

      Clinical Predictors for Lack of Favorable Vascular Response to Statin Therapy in Patients With Coronary Artery Disease: A Serial Optical Coherence Tomography Study
      Background Previous studies have demonstrated that statin therapy improves cardiac outcomes, probably by stabilizing thin‐cap fibroatheroma in patients with coronary artery disease. However, major adverse cardiac events still occur in some patients, despite statin therapy. The aim of this study is to identify clinical predictors for the lack of a favorable vascular response to statin therapy in patients with coronary artery disease. Methods and Results A total of 140 ...

      Dynamic neointimal pattern after drug-eluting stent implantation defined by optical coherence tomography
      Objectives: Certain neointimal patterns including neoatherosclerosis (NA) are known to be associated with poor clinical outcome. The prevalence and time course of different neointimal patterns have not been studied systematically. The aim of this study was to investigate the serial changes in neointimal pattern after drug-eluting stent implantation. Patients and methods: A total of 132 patients with 207 drug-eluting stents, who underwent two follow-up optical coherence tomography studies at 6 ...

      Is age an important factor for vascular response to statin therapy? A serial optical coherence tomography and intravascular ultrasound study
      Objective: Age-related structural and functional changes in vessel wall may affect the time course of vascular response to statin therapy. In this study, we sought to compare the response of lipid-rich plaque to statin therapy in elderly versus younger patients using optical coherence tomography and intravascular ultrasound. Patients and methods: Sixty-nine patients who underwent serial optical coherence tomography and intravascular ultrasound at the time point of baseline, 6, and 12 ...

      Objective Plaque rupture may be the local expression of a widespread coronary instability. This study aimed to investigate: (1) the prevalence and characteristics of nonculprit plaque rupture; (2) the pancoronary atherosclerotic phenotype in patients with and without nonculprit plaque rupture; and (3) the prevalence and predictors of multiple plaque ruptures. Approach and Results Six hundred and seventy-five nonculprit plaques from 261 patients (34 acute myocardial infarction, 73 unstable angina pectoris ...

      Does Residual Thrombus After Aspiration Thrombectomy Affect the Outcome of Primary PCI in Patients With ST-Segment Elevation Myocardial Infarction? An Optical Coherence Tomography Study
      Objectives The aim of this study was to evaluate if residual thrombus burden after aspiration thrombectomy affects the outcomes of primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction (STEMI). Background Recent studies failed to show clinical benefit of aspiration thrombectomy in STEMI patients. This might be due to insufficient removal of thrombus at the culprit lesion. Methods A total of 109 STEMI patients who underwent aspiration thrombectomy ...

      Three-dimensional morphological response of lipid-rich coronary plaques to statin therapy: a serial optical coherence tomography study
      Objective: Previous studies have suggested that intensive statin therapy, compared with moderate statin therapy, provided greater reduction of LDL and better protection against major cardiovascular events. However, the exact dose-dependent mechanism of plaque stabilization remains unclear. The aim of this study is to investigate the three-dimensional (3D) response of fibrous caps overlying lipid plaques to statin therapy. Methods: We applied a novel computer algorithm to investigate the fibrous cap 3D ...

      Serial Optical Coherence Tomography and Intravascular Ultrasound Analysis of Gender Difference in Changes of Plaque Phenotype in Response to Lipid-lowering Therapy
      Although the clinical benefit of statins have been demonstrated in both genders, gender differences in the response to statin therapy on plaque morphological changes have not been reported. A total of 66 non-culprit plaques from 46 patients who had serial image acquisition at baseline, 6 months, and 12 months by both optical coherence tomography (OCT) and intravascular ultrasound (IVUS) were included. Patients were treated with atorvastatin 60mg (AT60) or 20mg ...
