Active clinical trials for "Coronary Artery Disease"

Clopidogrel is crucial as antiplatelet treatment in patients undergoing percutaneous coronary intervention (PCI) with stent implantation and during one year after PCI, to prevent atherothrombotic complications. However, clopidogrel is ineffective in certain patients due to genetic mutation in CYP2C19 gene a specific enzyme in the liver required for metabolism of clopidogrel. Therefore, the purpose of this study is to test these patients genetically at bedside and prescribe an alternative drug such as Ticagrelor (90 mg twice daily) or prasugrel ( 10mg once daily or 5mg once daily if the patient older than 75 years or a body weight < 60kg) if they are carriers of the allele 2 or 3 of the mutated gene.

To evaluate the therapeutic evaluation of combination therapy with aspirin and salvianolate injection based on the population pharmacokinetics and TEG.A prospective, multicenter, randomized, controlled clinical trial is used.A total of 120 patients will be recruited and will be divided into three groups,respectively salvianolate injection group,aspirin group and salvianolate injection and aspirin group，and the course of treatment is 10 days.

MeRes-1 Extend study is designed as prospective, multinational, multicentre, single arm, open label, pilot study to assess the safety and performance of the MeRes100 Sirolimus Eluting Bioresorbable Vascular Scaffold System (BRS) in subjects with de novo native coronary artery lesions. 64 subjects will be enrolled from the 8 centers located in Asia Pacific, Europe, Brazil and South Africa. Primary outcome of study will be Proportion of population reporting Major Adverse Cardiac Events at 6 months from the day of index Procedure.

This is a prospective, multi-center, open label, randomized study to evaluate the efficacy and safety of The TIVOLI Biodegradable polymer Rapamycin-Eluting Stent comparing with The FIREBIRD2™ Rapamycin-eluting Stent (DES) for Treatment Coronary Revascularization.

The purpose of this study is to explore the effect of 20mg high loading dose of rosuvastatin on recurrent events in patients with established DM who is admitted for an ACS.

The investigators developed a modified regadenoson nuclear stress test of the heart that incorporates an aminophylline injection following regadenoson (The ASSUAGE protocol). The modified (ASSUAGE) protocol has been associated with fewer side effects and was better tolerated by patients. This study will investigate whether the modified regadenoson stress protocol (ASSUAGE) produces blood flow pattern to the heart similar to that of a standard regadenoson stress protocol. In proven to be the case, the ASSUAGE protocol has the potential to be used on a wide scale instead of the current standard protocol.

It is hypothesized that on-line modified ultrafiltration (MUFF) post-cardiopulmonary bypass will result in improved patient outcomes over the 12-hour post-operative period as compared to control and off-line MUFF.

This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES)

DES are preferred over BMS for most patients, however prolonged dual antiplatelet therapy is required for patients treated with DES for prevention of late or very late stent thrombosis. which increases a risk of major bleeding. BioFreedom is a Biolimus A9-coated stent that consists of a stainless steel stent platform with a textured abluminal surface without use of any polymer in the coating. Biolimus A9 rapid release and polymer-free property may give BioFreedom the advantages of both DES and BMS that may require less duration of DAPT. BioMatrix Flex, Biolimus-eluting stent with biodegradable polymer, also demonstrated safety and efficacy. We will compare these two difference types of Biolimus A9-eluting stents with different duration of DAPT. With proven adequate and safe duration, we will compare between one versus more than six months of dual antiplatelet therapy after Biolimus A9-eluting stents implantation using different properties of BioFreedom and BioMatrix Flex.
