OBJECTIVES We sought to examine the effect of angiotensin receptor blocker (ARB) on the formation of lesions in the aortic valves of hypercholesterolemic rabbits. BACKGROUND Recently, atherosclerosis has been recognized as a mechanism that is responsible for calcific aortic stenosis. The effect of ARBs might help to prevent aortic stenosis because they(More)
A 33-year-old man with a 4-year history of Behçet's disease was hospitalized with acute myocardial infarction. Percutaneous coronary intervention (PCI) treated 99% stenosis of the right coronary artery but follow-up coronary arteriography clearly revealed a coronary artery aneurysm (CAA) at the lesion proximal to the PCI site and intravascular ultrasound(More)
AIM The clinical relevance of the suggested pleiotropic effects of hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) is controversial. Aggressive statins effectively reduce lipid levels, but whether their other effects are more powerful than those of regular statins is unknown. METHODS We enrolled 32 patients (mean age, 65 y; male, 23) who(More)
The gap junction protein, connexin 43 (Cx43) might be involved in the development of atherosclerosis. However, little is known about Cx43 expression in human arteries. We histologically analyzed the distal portions of radial (RA) and internal thoracic arteries (ITAs) obtained from 29 patients undergoing coronary artery bypass graft surgery. The medial(More)
BACKGROUND A suitable animal model is required to investigate plaque biology. Here, we examined 6 rabbit models of plaque generated by balloon injury and sequential combinations of normal and high-cholesterol diets. METHODS AND RESULTS Fifty-eight male Japanese White rabbits were used. Lipid-rich macrophages accumulated in the center of the intima, and(More)
We report a patient with Takayasu arteritis (TA) who initially received stent placement (SP) following percutaneous transluminal balloon angioplasty for stenotic lesion of the left subclavian artery and subsequently had recurrent in-stent restenosis three times. Every time restenosis occurred, percutaneous transluminal rotational arterectomy (RA) was(More)
A 67-year-old woman was admitted with impaired general performance, suffering from fatigue, chest oppression on exertion, and paresthesia of the finger trips. The laboratory findings showed increased white blood cells with abnormal cells, and serum immunofixation test showed monoclonal IgM kappa paraprotein. On flow cytometric immunophenotyping with CD38(More)
