Filter by:The purpose of this study is to assess the affect of febuxostat on coronary artery flow in patients with coronary artery disease.
The purpose of this study is to determine whether preoperative loading dose atorvastatin can prevent perioperative myocardial infarction during angiography and main adverse cardiac events 1 month after operation in stable angina, unstable angina and acute non-ST-segment elevation myocardial infarction patients undergoing elective coronary angiography and PCI, and determine whether its mechanisms are associated with microcirculation resistance.
CTOs are common among patients with angina, and are detected in around 20% of patients undergoing coronary angiography. Treatment of CTO has been found to constitute only 7% of PCI practice on average. One of the reasons for the under-presentation of CTOs in PCI target lesions is the lack of evidence-based medical data on treatment indications, and the continued low level of accepted evidence for the treatment of CTOs by PCI in PCI guidelines. Patients with a CTO represent patients with stable coronary artery disease. The COURAGE trial comparing PCI with optimal medical therapy in stable coronary disease did not show a difference in mortality or myocardial infarction between the two treatment options. However, CTOs were not included in the COURAGE trial. But that trial did confirm the superiority of PCI over OMT in controlling symptoms of angina, with a high cross-over rate to PCI. Whether PCI for CTO is superior to OMT in reducing MACE in those patients with a large ischaemic burden has never been tested in a randomized controlled trial. While there is compelling evidence from registry studies of a clinical and prognostic benefit following successful PCI of CTO compared with PCI failure, there has been no randomized controlled trial of contemporary PCI using drug-eluting stents versus optimal medical therapy. The COURAGE trial nuclear sub-study confirms both that prognosis is closely related to the extent of residual ischaemia and that PCI is more effective in reducing residual ischaemia than optimal medical therapy alone. This confirms earlier retrospective data suggesting that the benefit of PCI is greatest in patients with moderate (10-20%) or severe (>20%) ischaemia. Study hypothesis: PCI with Biolimus eluting stent implantation plus OMT will be superior to OMT alone in improving health status at 12-month follow-up, and will be noninferior with respect to the composite of all cause death/ non fatal MI at 36-month follow up, in patients with a CTO in an epicardial coronary artery >2.5 mm diameter and chronic stable angina with evidence of ischemia and viability in the territory subtended by the CTO
The primary objective of this study ist to test the hypothesis that ticagrelor is superior to Aspirin (ASA) fort he prevention of major cardio- and cerebrovascular events (MACCE) in patients undergoing artery bypass operation. The primary efficiacy MACCE-endpoint is the composite of cardiovascular death, myocardial infarction, recurent revascularisation, and stroke at twelve month after coronary artery bypass operation.
The objective of this study is a comparative evaluation of BuMA stent and of EXCEL stent in terms of the extent of neointima formation at 3 months after implantation using OCT. This is a prospective, single center, randomized, open-label, non-inferiority study, which will enroll a total of 70 patients in Fuwai Hospital.All patients will be randomly assigned undergoing implantation of BuMA stent or EXCEL stent (in a 1:1 ratio). If non-inferiority was met, superiority test will be planned.
International guidelines support the use of a full-dose heparin (anticoagulants) during coronary intervention. However, a lower dose of heparin may be adequate, thanks to advances in angioplasty techniques and the widespread use of pretreatment with two antiplatelet agents. Thus the investigators designed a study comparing safety and efficacy of standard dose heparin (100 UI/Kg) versus low-dose (50 UI/Kg) in patients undergoing coronary angioplasty who are on aspirin and clopidogrel at the time of the procedure.
The role of lipids as risk factors for cardiovascular events is well-documented, although events studied have largely been broad classes without specific detail. This study will examine a more refined set of endpoints.
This trail aims to evaluate the efficacy of acupoints on the specific meridian for chronic stable angina pectoris, compared with acupoints on the other meridian, sham acupoints and waiting-list. And to confirm the specificity of acupoints on meridian.
The purpose of this study is to evaluate the effect of Danhong Injection on the relief of angina with the use of the Seattle Angina Questionnaire among patients with stable angina patients
Background: Vascular closure devices (VCD) were developed to reduce access site bleedings, to improve patients´ comfort, and to accelerate ambulation after percutaneous coronary interventions (PCI). Despite higher complications rates in earlier studies, current data suggest similar complication rates or better outcomes after the use of VCD as compared to manual compression. ExoSeal (Cordis, Warren, NJ, USA) is a new, extravascular polyglycol acid (PGA) plug which occludes the puncture channel. Whether the use of this extravascular closure device is as effective as the more widely used plug/anchor mediated devices, has not been evaluated so far. We performed a randomized, multicentre, single-blinded trial to compare the efficacy of the extravascular closure device ExoSeal in comparison to the collagen-based plug/anchor mediated AngioSeal system. Methods: 304 patients receiving diagnostic angiography and/or PCI will be included in three centers. Exclusion criteria are contraindications for any VCD including 1. severe calcification of the access vessel, 2. severe peripheral artery disease, 3. puncture in the origin of the profound femoral artery, 3. non-femoral sheath insertion, 4. marked tortuosity of the femoral or iliac artery, 5. marked obesity or cachexia (BMI >40 or <20) and 6. patients on continuous medication with oral anticoagulants. After the procedure, angiography of the accessed femoral artery is performed to rule out major risk factors for retroperitoneal hemorrhage, relevant peripheral stenoses of the common or the superficial femoral artery, or a location of the puncture site in the bifurcation of the profundal femoral artery. We hypothesise, that the use of an extravascular closure device is not inferior to an anchor/plug mediated device regarding the occurrence of the following complications: bleeding, need for vascular surgery and device failure (primary endpoints). Secondary endpoints are the occurrence of false aneurysms, severe pain (Borg ≥ 5), and hematoma ≥ 5 cm within 24 hours after insertion of the device. Power was 80%, alpha 0.05. Bleeding will be defined according to the TIMI criteria. The study is actively enrolling patients, last inclusion will take place in September 2012. Results and Conclusions: Outcome data including the primary endpoint (bleeding, need for vascular surgery and device failure) will be presented for the first time.
