background: the aim of the present study was to develop a scoring system for predicting 1-year major adverse cardiac events (mace), including mortality, target vessel or target lesion revascularization, coronary artery bypass graft surgery, and non-fatal myocardial infarction after percutaneous coronary intervention (pci). methods: the data were extracted from a single center pci registry. the ...

OBJECTIVES The aim of this study was to investigate the relation between coronary atherosclerotic plaque injury and activation of the coagulation cascade. BACKGROUND Thrombus formation after atherosclerotic plaque disruption has been implicated in the pathogenesis of atherosclerosis, unstable angina and myocardial infarction. METHODS Biochemical markers of thrombin generation (prothrombin f...

although thallium-201 exercise scintigraphy has been established for the detection of myocardial ischemia and viability, little is known regarding the myocardial thallium-201 kinetics during angioplasty. herein, we report a 77-year old man with angina pectoris, in whom serial myocardial imaging after a single dose of thallium-201 was helpful in identifying not only the culprit lesion and myocar...

OBJECTIVE The objective of this study was to assess the safety and efficacy of a polymer-free sirolimus coated, ultrathin strut drug-eluting stent (PF-SES) in an unselected patient population with a focus on acute coronary syndrome (ACS). Furthermore, stable coronary artery disease (CAD) with short (≤6 months) versus long (>6 months) dual antiplatelet therapy (DAPT) were also studied. METHODS...

Myocardial fractional flow reserve (FFR(myo)) and coronary flow reserve (CFR), measured with guidewire, and quantitative angiography (QA) are widely used in combination to distinguish ischemic from non-ischemic coronary stenoses. Recent studies have shown that simultaneous measurements of FFR(myo) and CFR are recommended to dissociate conduit epicardial coronary stenoses from distal resistance ...

OBJECTIVES We hypothesized that percutaneous transluminal coronary angioplasty performed on coronary stenoses that have demonstrated rapid angiographic progression would be associated with a high risk of restenosis. BACKGROUND High rates of restenosis have been documented after percutaneous transluminal coronary angioplasty of unstable lesions and of lesions that recur rapidly after a success...

BACKGROUND Plaque volume (PV) is related to major cardiovascular events (MACE) after coronary stent implantation. OBJECTIVE To evaluate the association between PV before the procedure evaluated by angiography and clinical outcomes. METHODS This is a prospective cohort study of patients undergoing coronary stent implantation in a referral center. PV before the stent implantation was evaluate...

Periprocedural neurological complications (PNCs) after carotid stenting were retrospectively analyzed to determine the risk factors with the use of various protective devices. Forty-three lesions in 40 patients were treated by carotid stenting with distal balloon protection for nearly all postdilation procedures and some predilation procedures. The following variables were statistically analyze...

BACKGROUND The advantages of the final kissing balloon technique (FKB) in a provisional 1-stent approach are under debate. Long-term clinical outcomes remain unclear due to limited data. METHODS AND RESULTS Of 2,132 patients (2,502 lesions) enrolled in the TAXUS Japan Postmarket Surveillance Study at 56 centers between July 2007 and December 2008, patients having coronary bifurcation treated ...

background: redo coronary artery bypass grafting surgery (cabg) is associated with a higher risk of mortality than the first operation. however, the impact of percutaneous coronary intervention (pci) on the outcome in such patients is currently unclear. we evaluated the in-hospital and six-month clinical outcomes of post-cabg patients who underwent pci in our center. methods: between april 2008...
