BACKGROUND Percutaneous coronary intervention (PCI) using drug-eluting stents significantly reduces the risk of restenosis in the general population. However, in patients on hemodialysis, adverse cardiac events are frequently seen even if treated with drug-eluting stents. Recent studies suggest that C-reactive protein (CRP) reflects vascular wall(More)
BACKGROUND Chronic haemodialysis patients are at an increased risk of peripheral artery disease (PAD). Although percutaneous transluminal angioplasty (PTA) has become a widely used therapeutic intervention for PAD, its outcome in haemodialysis patients remains poorly understood. The aim of this study was to clarify the long-term outcome of PTA as a primary(More)
Statin therapy moderately increases high-density lipoprotein cholesterol (HDL-C) levels. Contrary to this expectation, a paradoxical decrease in HDL-C levels after statin therapy is seen in some patients. We evaluated 724 patients who newly started treatment with statins after acute myocardial infarction (AMI). These patients were divided into 2 groups(More)
BACKGROUND Although percutaneous transluminal angioplasty (PTA) has become a common therapeutic standard for peripheral artery disease (PAD), high restenosis rates in the superficial femoral artery (SFA) remain a major problem. Nitinol stent implantation is reported to reduce restenosis in SFA after PTA in the general population; however, little is known(More)
Coronary artery bypass grafting (CABG) is an established treatment for multivessel coronary artery disease. However, problematic situations are occasionally encountered after CABG, such as disease progression in the native coronary artery with graft occlusion, which causes difficulty in revascularization. The purpose of this study was to evaluate changes in(More)
Albuminuria has traditionally been associated with an elevated risk of cardiovascular events. However, few studies have examined the potential relation between albuminuria and periprocedural risk in percutaneous coronary intervention (PCI). The aim of this study was to evaluate the impact of albuminuria on the incidence of periprocedural myocardial injury(More)
BACKGROUND Patients on maintenance hemodialysis (HD) are at high risk for restenosis after percutaneous coronary intervention (PCI) even if treated with a sirolimus-eluting stent (SES). The aim of this study was to compare the effects of SES and paclitaxel-eluting stent (PES) in preventing restenosis in HD patients with coronary artery disease. METHODS A(More)
BACKGROUND Percutaneous transluminal angioplasty (PTA) for femoropopliteal lesions in peripheral artery disease has been performed in patients undergoing hemodialysis as well as in the general population. Cilostazol, a selective inhibitor of phosphodiesterase 3, has been reported to reduce target lesion revascularization after PTA for femoropopliteal(More)
BACKGROUND Even in the drug-eluting stent era, adverse cardiac events, including restenosis after percutaneous coronary intervention (PCI), have been more frequently seen in patients on hemodialysis (HD) than in non-HD patients. The objective of this study was to compare the sirolimus-eluting stent (SES) and everolimus-eluting stent (EES) for prevention of(More)
BACKGROUND  Although revascularization via coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) has been widely performed, there are limited data on which procedure is best in hemodialysis (HD) patients. METHODS AND RESULTS  This 10-year follow-up study consisted of 997 HD patients electively undergoing coronary(More)
