Filter by:The purpose of this study is to evaluate the efficacy of a novel dual drug-eluting stent (DXR stent), which slowly releases both cilostazol and paclitaxel, for strut coverage, malapposition, and thrombus formation, assessed by an optical coherence tomography.
The purpose of this study is to determine whether a single intracoronary infusion of an adenovirus serotype 5 virus expressing the gene for human fibroblast growth factor-4 (Ad5FGF-4) is effective in improving angina-limited exercise duration, angina functional class, frequency of angina attacks, frequency of nitroglycerin usage, and quality of life. Half of the study participants will receive Ad5FGF-4, and half will receive placebo. The primary endpoint is the change from baseline to Month 6 in Exercise Tolerance Test (ETT) duration. Long-term safety of Ad5FGF-4 will also be assessed.
Prospective, multi-center, registry designed to enrol up to 2,000 patients in up to 35 International centers. All patients will receive a BioMatrix AlphaTM stent as per clinical practice and will be followed for 2 years for data collection. Major adverse cardiac events (MACE) results at 9 months will be compared to the results obtained from the BioMatrix FlexTM arm of the LEADERS trial.
The aim of this study is to evaluate early post-stress EF change (∆EF) and its relation to the severity of myocardial ischemia and angiographic coronary disease using CZT-SPECT MPI.
The aim of this study is to test for an early post-stress cardiac output (CO) change by impedance cardiography and its relation to the severity and extent of myocardial ischemia and angiographic coronary disease in subjects undergoing exercise stress testing using a novel cadmium-zinc-telluride (CZT) SPECT camera.
New CZT-based SPECT cameras are potentially capable of dynamic 3-D acquisition. Preliminary results suggested that dynamic acquisitions could allow the assessment of myocardial flow reserve using 99mTc-labelled perfusion tracers. The Flow-Heart study will assess the feasibility of myocardial flow reserve measurement by means of 99mTc-DTPA dynamic cardiac SPECT in 20 patients.
Prolonging infusions may decrease myocardial damage associated with bivalirudin use during primary PCI. The investigators hypothesized that continuing the bivalirudin infusion commenced during the procedure at the PCI recommended dose for 4 hours would prevent myocardial damage.
This is a single center, prospective study: The 'CardioGard Cannula' Gaseous emboli capture results - shows an improvement from the control group.
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.
In patients with ST elevation myocardial infarction (STEMI) the treatment goal is revascularization of the occluded artery with the use of primary percutaneous coronary intervention (PCI). There is a large subset of patients with STEMI who also have significant disease in arteries other than the site of occlusion, and away from the culprit artery. It is estimated that up to 50% have disease of more than 50% in the non-culprit arteries. The evidence on how to treat those patients with multi vessel disease is conflicting. Earlier large-scale studies and registries have suggested early and complete revascularization is of no benefit or even harmful. More recent studies have showed the opposite of that. The CVLPRIT study showed that early complete revascularization or preventive PCI reduced primary endpoint of a composite of all cause mortality, myocardial infarction and need for repeat revascularization. The benefit was mainly due to reduced repeat revascularization in the more intensive intervention group. The PRAMI study showed very similar results as well. The use of Fractional flow Reserve (FFR) in deciding complete revascularization has also showed conflicting results so far. A previous trial showed that FFR guided intervention post STEMI increased MACE. This was conflicted with more recent study, which showed FFR guided complete revascularization improved outcome when compared with more conservative treatment of ischaemia driven intervention. In this study, the investigators are going to assess the issue of staged revascularization guided by FFR or by angiogram, compared to the standard treatment of ischaemia driven revascularization
