Filter by:This is a randomized, open-label, single-dose, two-sequence, two-period crossover study to investigate the pharmacokinetics between a tablet containing 75 mg of Clopidogrel and 100 mg of Aspirin and the simultaneous administration of the separate formulations of the two drugs in healthy male volunteers.
The study aims at pooling a large population of patients with suspected coronary artery disease (CAD) who underwent Computed Tomography Coronary Angiography (CTCA) and who were adequately stratified in the first place. Then the investigators will be able to assess the incremental value of CTCA in the stratification of prevalence of disease (non obstructive/obstructive) and prognosis of patients with suspected CAD). The added information to current evidence is how reliable and to what extent CTCA can define the actual burden of disease and cardiovascular risk.
This multicentre, open-label, single-arm Study is to evaluate the effect of Rosuvastatin 20 mg 76 weeks on coronary atherosclerosis plaque versus baseline in Chinese coronary heart disease (CHD) patients with hyperlipidemia by measuring the plaque volume using a 64 slice spiral CT. Effect on blood lipids, hsCRP and Carotid intima-media thickness (CIMT) is also evaluated.
The aim of this study is to determine whether a pre-treatment with high-dose statin (one day prior and just before intervention, rosuvastatin 20mg/day) has a positive impact on the occurrence of periprocedural myocardial infarction during percutaneous coronary intervention (PCI).
Vascular effects evaluation after non-polimeric and polimeric paclitaxel stent implantation.In particular the investigators will use Taxus )as a polimeric stent)and Axxion (as a non-polimeirc)stent system. The investigators will look at late stent malapposition by means of intracoronary ultrasound imaging technique (IVUS) at baseline and 9 months follow-up. The investigators sought to compare the two stent types with the same drug to verify the polimer role. The polimer itself seems to provoke inflammation and hypersensibility if the arterial wall and it seems to be the base of a process of positive remodeling found at drug eluting stent implantation site. This positive remodeling is the mechanism producing late stent malapposition which on its turn can determine stent thrombosis, as demonstrated by pathological studies. At the same time the investigators will study the incidence of clinical events like myocardial infarction, stent thrombosis, TLR and death along with the incidence of angiographic restenosis at 2 years follow up.
Sirolimus-eluting stent (SES) has been proven to improve outcomes in patients with significant coronary artery diseae(> 70% lumen diameter narrowing). But, acute coronary syndrome may occur in those with intermediate lesions(50%-70% lumen diameter narrowing), and the effect of SES in these patients remains unclear. Here the investigators hypothesize that application of China-made SES may improve the clinical outcomes in these setting.
Drug-eluting stents effectively reduce restenosis but may increase late thrombosis and delayed restenosis. Persistent polymer could be responsible. Local delivery of paclitxel from a polymer-free Yinyi stent (Dalian Yinyi biomaterial research and development co.ltd) may prevent these complications.
Sirolimus-eluting stent (SES) has been world-widely used in clinical practice in treating patients with coronary artery disease (CAD). The efficacy and safety of Excel SES (JW Medical, Shandong, China, MA) with biodegradable polymer has been proved by several clinical trials. Here the investigators design a prospective, multicenter, randomized clinical study in purpose of identifying the non-inferiority in the efficacy and safety in treating CAD patients by Firebird 2 SES (Microport, Shanghai) with durable polymer, comparing with Excel SES.
The purpose of this study is to evaluate the efficacy of nicorandil in the achievement of maximal coronary hyperemia compared with adenosine.
The purpose of the study is to compare strut coverage and neointimal thickness between everolimus eluting (XIENCE-V® or PROMUS® stent) and biolimus A9 eluting NOBORI Stent 14 months after stent implantation and to determine the coronary endothelial function after everolimus eluting (XIENCE-V® or PROMUS® stent) and biolimus A9 eluting NOBORI Stent 14 months after stent implantation by using supine bicycle exercise testing to assess coronary vasomotor response to exercise.
