Background and purpose : CAD is the most important cause of mortality and morbidity in all orer the world. Aim of this study was to determine the effect of EDTA on the process of atherosclerosis. Materials and methods : The study is a randomized clinical trial. 14 patients whom were not suitable candidates for mechanical- Revascularization(PCI or CABG), were treated with EDTA injection twi...
BACKGROUND AND PURPOSE Endovascular treatment can improve the outcome of patients treated for ruptured intracranial aneurysms as compared with surgical clipping, but angiographic recurrences are frequent. Endothelial denudation before coil embolization may prevent recanalization and improve results of endovascular treatment. METHODS We compared angiographic and pathological results 3 months a...
BACKGROUND AND PURPOSE Early identification of patients at risk of angiographic vasospasm after aneurysmal subarachnoid hemorrhage (SAH) may mitigate its sequelae. One mechanism that may contribute to angiographic vasospasm is increased central sympathetic activity, which is also thought to cause electrocardiographic (ECG) changes after SAH. Here, we perform the first study to determine the ass...
OBJECTIVES The objectives of the study were to evaluate the effect of angiographic follow-up on revascularization rates in the TAXUS-IV trial and to determine whether the relative benefit of paclitaxel-eluting stent implantation compared with bare metal stent implantation was modified by angiographic follow-up. BACKGROUND Although several clinical trials have demonstrated that drug-eluting st...
BACKGROUND AND PURPOSE The presence of low-density areas on CT is used in clinical decision-making regarding treatment of angiographic vasospasm as well as in research as a surrogate marker for severity of angiographic vasospasm. We assess the interobserver variability in attributing hypodensities on CT to angiographic vasospasm-related delayed ischemic neurological deficit. METHODS Three exp...
OBJECTIVES We evaluated the long-term clinical and angiographic results of 'fused-gold' (NIRFlex Royal) and 'bare' (NIRFlex) stainless steel stents in patients undergoing percutaneous coronary intervention (PCI). BACKGROUND Recent studies have shown high clinical and angiographic restenosis rates following the intracoronary implantation of 'gold-coated' stainless steel stents. The new 'fused-...
OBJECTIVE To determine the relationship of anger and hostility to angiographic coronary artery disease (CAD), symptoms, and functional status among women with suspected CAD. METHODS Data were collected from 636 women with suspected CAD referred for diagnostic angiography in the Women's Ischemia Syndrome Evaluation (WISE) Study. CAD was assessed as angiographic presence/absence of disease (> o...
The development of preprocedural angiographic risk stratification criteria was meaningful in the balloon angioplasty era (1). Acute ischemic complications consisted of angiographic complications with impairment of epicardial coronary blood flow. The demonstration that these postpercutaneous coronary intervention (PCI) ischemic complications were related to the preprocedural angiographic complex...
