BACKGROUND The ability of iMap-intravascular ultrasound (IVUS) tissue characterization to detect thin-cap fibroatheroma (TCFA) identified on optical coherence tomography (OCT) has not yet been fully elucidated. METHODSANDRESULTS We evaluated 86 coronary lesions from 73 patients with stable angina pectoris using iMap-IVUS and OCT. We defined OCT-derived(More)
OBJECTIVES This study sought to determine whether systemic levels of pentraxin 3 (PTX3), a novel inflammatory marker, are associated with thin-cap fibroatheroma (TCFA). BACKGROUND Biomarkers predicting the presence of TCFA in vivo have not been established. METHODS We evaluated 75 patients (stable angina pectoris, n = 47; acute coronary syndrome, n =(More)
Coronary artery aneurysms are frequently asymptomatic and may be difficult to diagnose by cardiac imaging. We herein present a case of a coronary artery aneurysm of the right coronary artery due to medial mucoid degeneration mimicking an intra-atrial mass on echocardiography and magnetic resonance imaging, with the cause being diagnosed after surgery.
AIMS Echocardiography is widely used for screening pulmonary hypertension (PH). More recently developed two-dimensional speckle-tracking echocardiography (2D-STE) can assess regional deformation of the myocardium and is useful for detecting left ventricular dysfunction. However, its usefulness to assess right ventricular (RV) dysfunction is not clear.(More)
An inflammatory response is a key event for endothelial dysfunction. Pentraxin 3 (PTX3) is an inflammatory protein produced at inflammation sites such as leukocytes and vascular endothelial cells. Here, we compared the relationships between endothelial function assessed by flow-mediated dilation (FMD), and the levels of plasma PTX3 and high-sensitive(More)
The transradial approach has been used for coronary procedures, but this procedure carries a risk of injury to the endothelium of the radial artery. In this study, the vascular dysfunction caused by transradial catheterization was examined using reactive hyperemia peripheral arterial tonometry (RH-PAT), a recently developed technique for assessing(More)
BACKGROUND Medication adherence has an important influence on health outcomes in patients with chronic diseases. However, few studies have been performed in Japan to determine factors related to medication non-adherence. OBJECTIVE The aim of this study was to identify prescription factors related to medication non-adherence by investigating patient(More)
A 63-year-old Japanese woman with an adrenal tumor was transferred to our hospital due to cardiogenic shock. Right and left ventriculography showed severe hypokinesis of the middle segment and the apex in both ventricles, and an endomyocardial biopsy demonstrated a small number of necrotic myocytes and cellular infiltration. She was diagnosed with(More)
