Filter by:Comparatively analyze the safety and validity of Amplazter Cardiac Plug (ACP) device-using percutaneous left atrial appendage closure, and the medical treatment with dabigatran plus aspirin or dabigatran plus clopidogrel after 3months triple therapy (Dabigatran plus DAPT (dual-antiplatelet therapy)) in patient with coronary artery disease treated with drug-eluting stent, accompanying atrial fibrillation. Total of 670 patients [left atrial appendage occlusion registry with 100 ACP/ 570 anti-coagulation registry: (285 Dabigatran plus aspirin) and (285 Dabigatran plus clopidogrel) therapy)] will be comparatively analyzed the safety and efficacy. Primary endpoints were a composite of death, non-fatal myocardial infarction, stroke, systemic embolism, and GUSTO bleeding (moderate to severe).
Design: Single center, single-blind randomized controlled trial of patients with high risk native coronary artery lesions (defined as ≥2 contiguous yellow blocks on the block chemogram) requiring clinically indicated percutaneous coronary intervention. Patients will be randomized to either a combined intervention or conventional PCI. Cardiac biomarker measurements will be performed before PCI and 18-24 hours later. Treatment: Combined intervention consisting of pre-PCI intracoronary vasodilator and glycoprotein IIb/IIIa inhibitor administration, use of an EPD if technically feasible, and complete coverage of the lipid core plaque, if technically feasible. Control: Conventional PCI. Duration: 30 days follow-up. The primary trial objective is to compare the incidence and size of periprocedural MI, as assessed by the peak post-PCI troponin distribution in the two study groups. The secondary endpoints are: (1) Reduction in the incidence of >3x and >10x upper limit of normal increase in CK-MB. (2) Reduction in the incidence of slow flow/no-reflow post PCI. (3) Lower incidence of major adverse cardiac events, defined as the composite of death, acute coronary syndrome, or coronary revascularization) during 30-day follow-up.
This is a Phase 2a randomized, double-blind (subject/investigator blinded, MedImmune unblinded), placebo-controlled, dose-escalation study to evaluate the safety, PK/PD, and immunogenicity of single IV and SC MEDI6012 doses in adult subjects with stable CAD.
This study is designed to test the hypothesis that the Biguard stent system will lead to fewer target lesion failure compared to regular stent system in patients with coronary bifurcation lesions at one year.
Inflammation in the arteries of the heart may increase the risk of cardiac death. The proposed research seeks to identify the potential beneficial role of a safe anti-inflammatory medication, colchicine, on reducing damage caused by opening up a blockage in the arteries of the heart. With its quick onset of action and excellent safety profile, colchicine may have the potential to reduce risk of major adverse events related to the heart. This research also seeks to better understand the role of neutrophils, the most common type of inflammatory white blood cell in the body, when there is damage to the heart.
The purpose of this study is to evaluate the relative effectiveness and safety of Onyx stent compared to other (drug eluting stents) DES.
In many large trials, reducing low density lipoprotein (LDL) levels with rosuvastatin decreased the incidence of major cardiovascular events，but little attention to the effects of rosuvastatin on HDL level，especially on HDL subtype. Epidemiological evidence strongly favors the notion that the risk of cardiovascular disease (CVD) is inversely related to the plasma high-density lipoprotein (HDL) cholesterol concentration. HDL can be subdivided into large-sized (HDL2a, HDL2b) and small-sized subclasses (preb1-HDL, HDL3c, HDL3b, HDL3a) and preb2-HDL. Some studies indicate that only large HDL2a and HDL2b particles make HDLs possess anti-atherogenic functions. The investigators assume that rosuvastatin could play the role of anti-atherosclerosis though the levels of HDL2a、HDL2b increased.
To evaluate the safety and effectiveness of computed tomography angiography in the diagnostic and therapeutic cycle as the first-choice method of imaging in the diagnosis of patients with a high probability of stable coronary artery disease according to European Society of Cardiology recommendations.
After successful coronary angiography and OCT examination, patients with TCFAs in non-culprit, mild-to-moderate stenotic lesions will be enrolled. Then, they will be randomly assigned in a 1:1 ratio to receive either atorvastatin (20 mg/day) alone or atorvastatin (20 mg/day）plus ezetimibe（10 mg/day）by envelope method. Angiographic and OCT follow-up will be scheduled for the target vessel after 12 months.
Patients that have cardiac surgery may suffer from unrecognized cerebral ischemia or loss of blood flow to the brain temporarily during surgery. This temporary loss of blood flow to the brain may result in a condition called delirium. Delirium is a type temporary confusion. There are some strategies that can help reduce cerebral ischemia during cardiac surgery which can help lead to a reduction in the incidence of delirium. The investigator believes that a strategy called remote ischemic preconditioning will help to reduce the incidence of delirium incidence after cardiac surgery. Remote ischemic preconditioning is a brief exposure to ischemia. This brief exposure to ischemia occurs in an area of the body that is not undergoing a procedure. This brief exposure to ischemia is not long enough to cause any damage to the body and it has been demonstrated to help protect against more severe ischemic injury that may occur later during surgery. In this study the investigator will use remote ischemic preconditioning to see if it can reduce the incidence delirium after cardiac surgery.
