    1. Identification of plaque ruptures using a novel discriminative model comprising biomarkers in patients with acute coronary syndrome

      Identification of plaque ruptures using a novel discriminative model comprising biomarkers in patients with acute coronary syndrome

      Soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1), neutrophil gelatinase-associated lipocalin (NGAL), and matrix metalloproteinase-9 (MMP-9) are inflammatory biomarkers involved in plaque destabilization resulting in acute coronary syndrome (ACS). This study aimed to investigate the diagnostic value of a combination of biomarkers to discriminate plaque ruptures in the setting of ACS. Eighty-five ACS patients with optical coherence tomography (OCT) images of the culprit plaque were included and categorized into two groups: ACS with plaque rupture (Rupture group, n = 42) or without plaque rupture (Non-rupture group, n = 43) verified by OCT. A discriminative model of plaque rupture using several biomarkers was developed ...

    2. Effects of lowest-dose vs. highest-dose pitavastatin on coronary neointimal hyperplasia at 12-month follow-up in type 2 diabetic patients with non-ST elevation acute coronary syndrome: an optical coherence tomography analysis

      Effects of lowest-dose vs. highest-dose pitavastatin on coronary neointimal hyperplasia at 12-month follow-up in type 2 diabetic patients with non-ST elevation acute coronary syndrome: an optical coherence tomography analysis

      Current ACC/AHA guidelines recommend high-dose statin therapy after coronary stenting, especially in diabetic patients; however, pitavastatin 4 mg or pitavastatin 1 mg are frequently used after coronary stenting in Asia, even in patients with acute coronary syndrome. We compared the effects of highest-dose and lowest-dose pitavastatin therapy on coronary neointimal hyperplasia at 12-month follow-up in diabetic patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) using optical coherence tomography. A total of 72 diabetic patients with NSTE-ACS were randomized to lowest-dose pitavastatin [1 mg ( n  = 36)] or highest-dose pitavastatin [4 mg ( n  = 36)] after everolimus-eluting stent implantation. The primary endpoint was ...

    3. Different optical coherence tomography findings for intracoronary stripe-like filling defects on coronary angiogram in patients with acute coronary syndrome

      Different optical coherence tomography findings for intracoronary stripe-like filling defects on coronary angiogram in patients with acute coronary syndrome

      Stripe-like radiolucent filling defects visualized by conventional coronary angiogram (CAG) usually suggest coronary artery dissection. However, recent endovascular imaging technique with high resolution power such as optical coherence tomography (OCT) makes more detailed intraluminal lesion characterization possible, compared with the conventional CAG, and attests to possibilities of being different clinical situation [1]. We report that stripe-like radiolucent filling defects on CAG proved to have different pathophysiologies by OCT in patients with acute coronary syndrome.
