    1. Lipoprotein (a) level is associated with plaque vulnerability in patients with coronary artery disease: An optical coherence tomography study

      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 ...

    2. Zero-Contrast Optical Coherence Tomography- and Physiology-Guided Percutaneous Coronary Intervention for Severely Calcified Lesion

      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 ...

    3. Incidence, factors, and clinical significance of cholesterol crystals in coronary plaque: An optical coherence tomography study

      Incidence, factors, and clinical significance of cholesterol crystals in coronary plaque: An optical coherence tomography study
      Background and aims Intraplaque cholesterol crystal (CC) is recognized as a component of vulnerable plaques. However, the clinical characteristics of patients with CC and the impact of CC on clinical events remain unknown. Methods A total of 340 consecutive patients who underwent optical coherence tomography (OCT) imaging of culprit lesions were included in the study. CC was defined as a thin linear structure with high reflectivity and low signal attenuation ...

    4. Low eicosapentaenoic acid to arachidonic acid ratio is associated with thin-cap fibroatheroma determined by optical coherence tomography

      Low eicosapentaenoic acid to arachidonic acid ratio is associated with thin-cap fibroatheroma determined by optical coherence tomography
      Background A low eicosapentaenoic acid (EPA)/arachidonic acid (AA) ratio is known to be associated with cardiovascular events. However, the relationship between the EPA/AA ratio and coronary plaque vulnerability assessed by optical coherence tomography (OCT) has not been examined thoroughly. This study examined the relationship between the EPA/AA ratio and coronary plaque vulnerability assessed by OCT in patients with acute coronary syndrome (ACS). Methods We evaluated 59 ACS ...
