Active clinical trials for "Myocardial Ischemia"

To assess the safety and feasibility of the use of the Tryton bifurcation coronary stent system for the treatment of single de novo bifurcation lesions in native coronary arteries.

Pressure intermittent coronary sinus occlusion (PICSO) in patients with coronary artery disease improves collateral flow index to higher than 30%. PICSO used in this patient population is safe, feasible and effective. Safety, feasibility and effectiveness will be tested by periprocedural and logistic data.

The purpose of this study is to document the safety and overall clinical performance of the Endeavor Resolute Zotarolimus-Eluting Coronary Stent System in a patient population with long lesion(s) and/or dual vessels requiring stent implantation.

The purpose of this Clinical Evaluation is the continued assessment of the XIENCE Everolimus Eluting Coronary Stent System (XIENCE V® and XIENCE PRIME™ EECSS) with the primary focus on clinical outcomes in the treatment of female patients with de novo coronary artery lesions, and the characterization of the female population undergoing stent implantation with a XIENCE stent.

The purpose of this research study is to determine if the infusion of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in patients with symptomatic severe coronary ischemia. In this trial we will study the safe use of this therapy and its effects on making new blood vessels will be evaluated. Coronary ischemia is intractable angina due to severe coronary artery disease which can seriously decrease blood flow to the heart. CI needs a comprehensive treatment since the condition will not improve on its own. The overall goal of the treatment is to increase blood flow to the heart and improve symptoms of angina. The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriate blood supply to the heart. Patients eligible to participate in this study are those suffering from severe blockages to the vessels of the heart and are not candidates for percutaneous revascularization or surgical procedures. Once the final mixture of stem cells is prepared, the cells will be intracoronary infused through a catheter into the blocked vessel of the heart. Studies will be performed to evaluate if the intracoronary infusion of stem cells is safe, feasible and works. Patients will be evaluated for 6 months after cell transplant.

The purpose of this study is to evaluate a new angioplasty catheter, AngioSculpt® for the treatment of bifurcation lesions (blockages occurring at branch points) in coronary arteries.

The study is designed to assess safety and effects of vorapaxar, when added to standard of care (aspirin and clopidigrel), in Japanese subjects with acute coronary syndrome. The study may also provide information about the effect of vorapaxar on preventing heart attack and stroke in this subject population.

This study is a prospective study of patients treated at Scripps Clinic with intracoronary brachytherapy for recurrent restenosis within drug eluting stents.

Adequate platelet inhibition before percutaneous coronary intervention (PCI) reduces peri-procedural and long-term ischemic complications. Documented reduced response to clopidogrel has been associated with subsequent major adverse cardiovascular events. Strategies to optimize platelet inhibition pre-PCI are under investigation. This study sought to evaluate the effect on platelet aggregation of four different dosing regimens of clopidogrel given before elective PCI.

We conduct this clinical trial to determine the effects of Xuefu Zhuyu capsule (based on TCM "Zheng Hou" theory) in helping recovery from coronary heart disease(CHD)after PCI and find out whether this kind of effecacy is much better within patients administered with TCM syndrome-based individualized medication.
