    2. Systemic and local factors associated with reduced thrombolysis in myocardial infarction flow in ST-segment elevation myocardial infarction patients with plaque erosion detected by intravascular optical coherence tomography

      Systemic and local factors associated with reduced thrombolysis in myocardial infarction flow in ST-segment elevation myocardial infarction patients with plaque erosion detected by intravascular optical coherence tomography
      Local factors of plaque rupture (e.g. lipid burden) are related to preprocedural thrombolysis in myocardial infarction (TIMI) flow grade during primary percutaneous coronary intervention (PCI). However, the pathological mechanism differs between plaque erosion and rupture. We aimed to identify the factors associated with reduced TIMI flow in plaque erosion. A total of 329 ST-segment elevation myocardial infarction (STEMI) patients with optical coherence tomography (OCT) identified plaque erosion were divided ...

    5. Incidence and Predictors of Neoatherosclerosis in Patients with Early In-Stent Restenosis Determined Using Optical Coherence Tomography

      Incidence and Predictors of Neoatherosclerosis in Patients with Early In-Stent Restenosis Determined Using Optical Coherence Tomography
      Summary In-stent restenosis (ISR) still exists after drug-eluting stent (DES) implantation, even up to one year. The incidence and risk factors for neoatherosclerosis in patients with early ISR have not yet been elucidated. Here, we used optical coherence tomography (OCT) to evaluate the incidence and predictors of neoatherosclerosis in patients with early ISRs. OCT was performed on ISR lesions in 185 patients in order to detect neoatherosclerosis. The median follow-up ...

    6. Unexpected Findings and Tailored Treatments of In-Stent Restenosis: Novel Insights from Optical Coherence Tomography

      Unexpected Findings and Tailored Treatments of In-Stent Restenosis: Novel Insights from Optical Coherence Tomography
      A 68-year-old man was admitted to our hospital with unstable angina. His medical history was remarkable for an acute myocardial infarction one year ago, treated with a zotarolimus-eluting stent (3.530 mm) in the mid right coronary artery. Coronary angiography showed a diffused in-stent restenosis (ISR) with haziness and filling defects (Figure 1A, Video 1). In order to identify the underlying mechanisms of ISR, optical coherence tomography (OCT) was performed ...

    7. The association between glucose-related variables and plaque morphology in patients with ST-segment elevated myocardial infarction

      The association between glucose-related variables and plaque morphology in patients with ST-segment elevated myocardial infarction
      Plaque rupture (PR) and plaque erosion (PE) are main causes of acute myocardial infarction with different demographic and histology characteristics and need different treatment strategy. PR and PE can be identified with optical coherence tomography (OCT) accurately, but convenient and effective noninvasive markers for them are rarely found. History of diabetes mellitus (DM) was reported to be a potential predictor of PR in ST-segment elevated myocardial infarction (STEMI) patients, but ...

    8. Relationship between elevated plasma ceramides and plaque rupture in patients with ST-segment elevation myocardial infarction

      Relationship between elevated plasma ceramides and plaque rupture in patients with ST-segment elevation myocardial infarction
      Background and aims Ceramides (Cer) is an atherogenic substance. However, the associations between specific plasma Cer levels and culprit plaque morphology in ST-segment elevation myocardial infarction (STEMI) patients are unclear. Methods The study consisted of two parallel cohorts. 100 consecutive patients with STEMI were screened as discovery cohort. In the validation cohort, we separately screened 30 normal donors, 30 stable angina pectoris (SAP) and 315 STEMI patients. All STEMI patients ...

    9. Plasma Ceramides in Relation to Coronary Plaque Characterization Determined by Optical Coherence Tomography

      Plasma Ceramides in Relation to Coronary Plaque Characterization Determined by Optical Coherence Tomography
      Plasma ceramides (Cer), a subset of bioactive lipids, have mechanistic links to development of atherosclerosis and are related to major adverse cardiovascular events (MACEs). Previous researches have demonstrated vulnerable plaques contribute to acute cardiovascular events and poor prognosis. This study aimed to explore the associations between Cer and culprit plaque characterizations evaluated by optical coherence tomography (OCT). It was found that plasma Cer are associated with culprit plaque vulnerability evaluated ...

      In-stent restenosis and longitudinal stent deformation: a case report
      Background Longitudinal stent deformation (LSD) is an infrequent complication of percutaneous coronary intervention (PCI), and it may lead to catastrophic clinical outcomes. However, reports of cardiac adverse events associated with LSD are rare. Case presentation A 55-year-old man with chest pain was treated for a severe left anterior descending branch (LAD)-diagonal 1 (D1) bifurcation lesion by PCI with two stents in the proximal LAD. LSD occurred during the withdrawal ...
