It is known that autonomic nervous activities change in correspondence with sleep stages. However, the characteristics of continuous fluctuations in nocturnal autonomic nerve tone have not been clarified in detail. The study aimed to determine the possible correlation between the electroencephalogram (EEG) and autonomic nervous activities, and to clarify in(More)
OBJECTIVES We assessed the predictive value of minimum stent area (MSA) for long-term patency of sirolimus-eluting stents (SES) implantation compared to bare metal stents (BMS). BACKGROUND Although MSA is a consistent predictor of in-stent restenosis, its predictive value in BMS is still limited because of biologic variability in the restenosis process.(More)
BACKGROUND Obesity has been reported to be associated with coronary artery disease and other atherosclerotic diseases. Recently, evidence has accumulated indicating that intra-abdominal visceral fat accumulation contributes to atherogenesis; however, the mechanism underlying this remains to be determined. This study was undertaken to elucidate whether(More)
BACKGROUND Red wine polyphenols have been shown to contribute to the "French paradox" phenomenon, which consists of lower morbidity and mortality from coronary heart disease in the French population. Although vascular smooth muscle cell (VSMC) proliferation plays an important role in the progression of atherosclerotic lesions, the effects of red wine(More)
BACKGROUND Estrogen replacement attenuates the increased risk of cardiovascular disease in postmenopausal women. Recent studies using an in vitro culture system have shown that estrogen inhibits endothelial cell (EC) apoptosis. The in vivo relevance of this finding, however, is not defined. To do so, we have developed a rat vascular injury model in which EC(More)
OBJECTIVES The aim of this study was to compare the effects of paclitaxel, sirolimus, and everolimus on the senescent phenotype in human endothelial cells, and to further investigate possible involvement of mammalian sirtuin 1 (Sirt1) down-regulation as a mechanism. BACKGROUND Endothelial cell senescence may play a role in impaired re-endothelialization(More)
PURPOSE Transient left ventricular dysfunction in patients under emotional or physical stress, also known as tako-tsubo-like left ventricular dysfunction, has been recently been recognized as a distinct clinical entity. The aims of this review are to define this phenomenon and to explore its similarities to the left ventricular dysfunction seen in patients(More)
OBJECTIVE This study aimed to evaluate the relationship between the occurrence of the angiographic no-reflow phenomenon in patients with acute myocardial infarction (AMI) and the preintervention plaque composition as assessed by virtual histology intravascular ultrasound (VH-IVUS). BACKGROUND The angiographic no-reflow phenomenon is an adverse prognostic(More)
