Active clinical trials for "Angina, Unstable"

The investigators aim to investigate the effect of oral nicorandil on neointima after coronary drug-eluting stent implantation in patients with diabetic mellitus.

The aim of the study is to examine the efficacy of Paclitaxel injection after a stent implantation in patients with stenosis in native coronary arteries to prevent restenosis in comparision with two admitted therapies.

The purpose of this study is to determine whether patients undergoing coronary intervention that also require oral anticoagulation, treatment with the COBRA PzF stent plus 14-day dual anti-platelet therapy (DAPT) has higher safety and non-inferior outcomes for thrombo-embolic events than compared with standard FDA-approved drug eluting stent (DES) plus 3 or 6-month DAPT.

This study evaluates the Efficacy and Safety of Paclitaxel-Coated Balloon Catheter in Patients With Diffuse Long De Novo Lesions of Main Coronary Arteries.

This study evaluates the clinical efficacy of Xuefu Zhuyu Decoction in the treatment of unstable angina pectoris. All of the patients will be divided into 2 arms randomly. One of the arms will be treated by conventional western medicine, the other one will be treated by Xuefu Zhuyu Decoction at the base of conventional western medicine.

This pilot randomized controlled trial aims to evaluate the feasibility for safety examination of continued metformin therapy in patients with type 2 diabetes (T2D) following invasive coronary angiography. Metformin will be continued until coronary angiography.

The purpose of this study is to collect additional safety and effectiveness data for on the Biosensors BioFreedom™ BA9 Drug Coated Coronary Stent in patients with native, de novo coronary artery disease.

The introduction of drug-eluting stents (DES) in the treatment of coronary artery disease has led to a significant reduction in morbidity. However, the first generation of these devices had no positive impact on the mortality after PCI (compared to bare metal stents), which was greatly attributed to a somewhat increased incidence of late and very late stent thrombosis. Concerns about the role of durable polymers as a potential trigger of inflammation and finally adverse events also led to the development of DES with bioresorbable coatings, which leave after degradation of the coating only a bare metal stent in the vessel wall that does not induce an inflammatory response. While such bioresorbable polymer DES are increasingly used in clinical practice, data from head-to-head comparisons between bioresorbable polymer DES with a contemporary highly flexible new generation permanent polymer coated DES.

This study evaluates the clinical efficacy of the famous prescription in the treatment of unstable angina pectoris. All of the patients will be divided into 4 arms according to their syndrome type. One of the arms will be treated by conventional western medicine, the other three will be treated by different Chinese herbal medicine prescription at the base of conventional western medicine.

The purpose of this study is to evaluate the efficacy (reduction of major ischemic events at 6 and 12 months of follow-up) of a tailored clopidogrel therapy in patients with UA/NSTEMI undergoing PCI with stent implantation and wiht a documented residual platelet reactivity assessed by a point of care system (VerifyNow P2Y12).
