Filter by:Previous studies comparing on-pump and off-pump operating strategy did only partially demonstrate benefits of the off-pump myocardial revascularisation.In primary end-points (MI, death, renal failure, and so on) there was no significant difference, but in secondary end-points we observed benefits resulting for patients. We would like to show the benefit of the method without extracorporeal circulation in patients with higher and hight operation risk, coming from EuroSCORE classification system (6 points and more).
The purpose of this study is to evaluate the safety and effectiveness of the Conor Sirolimus-eluting Coronary Stent System in the treatment of coronary artery disease (a single atherosclerotic lesion) in native coronary arteries. The study will evaluate the outcomes of a new drug-eluting stent compared to an approved drug-eluting stent. While Cordis made a business decision to no longer pursue NEVO™ development and commercialization, the patients will be followed up as per protocol. This includes performing all protocol required follow-up visits and the collection and reporting of all safety information.
The investigators' hypothesis is that restriction of circulating fluids in comparison to a liberal fluid administration policy would lead to a reduction of allogenic red blood cells exposure in patients undergoing cardiopulmonary bypass (CPB) for primary coronary artery bypass graft supported by reinfusion of washed shed blood from thoracic cavities.
The goal of the main trial was to evaluate the effect of low dose hormone replacement therapy with 1 mg norethindrone/10mcg ethinyl estradiol in postmenopausal women with a history of chest discomfort, myocardial ischemia and no obstructive CAD. For the purposes of this study as a core lab coordinating center, the investigators will be performing P31 MRS core lab analyses; hormone core lab analyses; lipid core lab analyses; glucose, insulin and HOMA core lab analyses; exercise stress test/Holter monitor core lab analyses; brachial artery reactivity test core lab analyses; full study data analyses for manuscript preparation and the writing and submission and publication of manuscript. The main trial duration: December 1999 - May 2003. The ancillary data analysis project duration: April 2006 - March 2010.
People with diabetes mellitus are more prone to coronary heart disease, stroke, and peripheral vascular disease, and diabetes mellitus has been regarded as an independent risk factor for the progression of coronary artery disease. Several studies have been reported that diabetes increased the risk of cardiovascular mortality in both men and women. With the introduction of drug-eluting stents (DESs), the angiographic rates of restenosis at later months have reduced dramatically in several studies. However, even with DESs, diabetic patients showed increased rates of restenosis and late loss index compared with nondiabetic patients. Diabetes has been considered to be a predictor of poor prognosis after percutaneous coronary intervention with drug-eluting stents. Long-term clinical and angiographic outcomes after percutaneous coronary intervention (PCI) with drug-metal stents (DESs) have been demonstrated to be worse in diabetic patients compared with nondiabetic patients. In the era of DESs, no study has compared the effects of telmisartan and valsartan on neointima volume with intravascular ultrasound (IVUS) at 8 months after zotarolimus-eluting stent implantation in hypertensive type 2 diabetic patients. Telmisartan, which is well-known for its selective peroxisome proliferator-activated receptor (PPAR)-γ activity with its anti-inflammatory and antiproliferative properties, could be an appropriate therapeutic option for treating hypertensive diabetic patients with significant coronary artery diseases requiring stent implantation. In contrast, valsartan is an angiotensin receptor blocker with negligible PPAR-γ activity. Increasing interest remains in the identification of systemic pharmacological therapies to prevent coronary restenosis especially in diabetic patients.
The purpose of this study is to determine whether a new cerebral oxygenation monitoring device is comparatively similar to the current approved devices.
For lesions which develop restenosis after a drug-eluting stent, it is not known which the right strategy to use is, implantation of the same type of DES as the initial one or a DES with a different drug.
The aim of this study is to determine whether biodegradable polymer based rapamycin-eluting stent performs equal to permanent polymer based everolimus- and rapamycin-eluting stents regarding reduction of adverse cardiac events at one year.
The purpose of this trial is to evaluate the efficacy of Rapamycin- and Zotarolimus-Eluting stents for the reduction of Coronary Restenosis
The study will evaluate the feasibility and safety of radial approach in patients undergoing coronary catheterisation without any restrictions based on the results of Allen's test.
