Background- Inflammation plays a key role in the pathophysiology of myocardial ischemia/reperfusion (I/R) injury; however, the mechanism by which myocardial I/R induces inflammation remains unclear. Recent evidence indicates that a sterile inflammatory response triggered by tissue damage is mediated through a multiple-protein complex called the(More)
This report describes a case of traumatic incomplete rupture of the ventricular septum, a rare complication caused by blunt chest trauma. Although a serial ECG progressed its course similar to acute anteroseptal myocardial infarction in this case, there was little clinical clue of septal tear. The diagnosis was established by transthoracic echocardiography.(More)
This report concerns two patients with severe protein losing enteropathy and refractory diarrhea due to AA amyloidosis who were successfully treated with corticosteroid and octreotide. In these patients, biopsied tissues from the gastrointestinal (GI) tract showed extensive deposition of AA amyloid, which was caused by rheumatoid arthritis in one case and(More)
Atrial fibrillation (AF) is associated with oxidative stress and elevated brain natriuretic peptide (BNP) levels. However, the exact cardiac origin of oxidative stress and its association with BNP levels in AF patients remain unclear. Therefore, we investigated the chamber-specific plasma oxidative stress levels in patients with paroxysmal AF (PAF) and(More)
BACKGROUND Statins reduce the incidence of cardiovascular events, but no randomized trial has investigated the best statins for secondary prevention. We compared the efficacy of hydrophilic pravastatin with that of lipophilic atorvastatin in patients with acute myocardial infarction (AMI). METHODS AND RESULTS A prospective, multicenter study enrolled 508(More)
BACKGROUND Hyaluronan (HA) is a primary component of the extracellular matrix of cells, and it is involved in the pathogenesis of atherosclerosis. The purpose of this study was to investigate the role of HA in neointimal formation after vascular injury and determine its tissue-specific role in vascular smooth muscle cells (VSMCs) by using a cre-lox(More)
AIMS Increasing evidence suggests that CD4(+) T cells contribute to neovascularization in ischaemic tissue. However, the T cell subset responsible for neovascularization after ischaemia remains to be determined. Here, we investigated the role of Th17 cells secreting interleukin (IL)-17, a newly identified subset of CD4(+) T cells, in the neovascularization(More)
BACKGROUND Atherosclerosis is believed to be caused by oxidative stress. Endovascular therapy (EVT) is effective for claudication of patients with peripheral artery disease (PAD). However, its effect on oxidative stress in PAD patients is unknown. Here, the impact of EVT on oxidative stress in PAD patients is investigated. METHODS AND RESULTS Twenty-five(More)
Inflammatory biomarkers have been proposed for use in the risk stratification of patients with acute myocardial infarction (AMI). We examined the value of inflammatory biomarkers over clinical features for predicting cardiovascular (CV) events in stable outpatients with MI. We enrolled 430 post-MI patients and measured their levels of high-sensitivity C(More)
BACKGROUND Statins reduce the incidence of cardiovascular events in patients with acute myocardial infarction (AMI). Although all statins are equally effective in secondary prevention, there might be certain differences in the effects of lipophilic and hydrophilic statins. Therefore, our aim is to compare the effectiveness of lipophilic atorvastatin and(More)
