Filter by:The purpose of this study is to compare standard therapy (risk factor control, life style modification) versus standard therapy plus low-dose rosuvastatin therapy (5mg/day) on progression of coronary atherosclerosis in statin naive individuals who have mild CAD (nonobstructive coronary atherosclerotic plaques) and normal LDL (low-density lipoprotein) cholesterol levels(〈130mg/dl).
This is a multi-center, single-blind, randomized, active-controlled, clinical trial in Percutaneous Coronary Intervention (PCI) subjects. Subjects will be randomized to receive the Combo stent as the investigational treatment arm or an Everolimus Eluting Stent (EES) as the active-control arm.
Prasugrel and ticagrelor were both associated with a significant reduction in the risk of MACE in patients undergoing PCI for an ACS, mostly through a reduced stent thrombosis. The 1-year relative risk reduction (RRR) of definite of probable stent thrombosis in patients receiving a DES were fairly different in TRITON-TIMI 38 and PLATO trials. The incidence of "biologically active" stent (DES or BVS) thrombosis is largely variable according to different lesion settings. We aim to verify the translation of the postulated different reduction in thrombosis rate among various P2Y12 inhibitors (clopidogrel, prasugrel and ticagrelor) in a high-risk setting such as the PCI with DES or BVS in CTO and bifurcating lesions.
To demonstrate the incremental utility of SSF for individuals undergoing CCTA, with expected improvements in image quality and diagnostic accuracy.
Background: - Magnetic resonance imaging (MRI) is type of imaging study that uses magnetic fields and radio waves to take pictures of the body. To help the images show up more clearly, a contrast agent is injected into a vein. Researchers are interested in finding contrast agents that can help show problems with the blood vessels around the heart. They want to test an agent called Gadofosveset Trisodium to see how it works in MRI scans. Objectives: - To test the effectiveness of Gadofosveset Trisodium as a contrast agent in heart MRI scans. Eligibility: - Healthy volunteers between 18 and 45 years of age. Design: - Participants will be screened with a physical exam and medical history. They will provide blood samples before the scanning sessions. - Participants will have an MRI scan after the screening visit. They will have a dose of the contrast scan before the study. - Participants will return for one additional MRI scan within 1 to 2 months of each scan. Different doses of the contrast agent will be used for each scan. - An additional blood sample will be collected within 1 week of the second MRI scan.
The objective of this study is to compare reduced-dose prasugrel and standard dose clopidogrel in patients older than 74 years with ACS, including non-ST-elevation (NSTEACS) and ST-elevation (STEMI) patients, undergoing early PCI. The primary endpoint of the trial will be the one-year composite of (all-cause)death, myocardial infarction, stroke and re-hospitalization due to cardiovascular reasons or bleeding.
This study investigates whether chronic heart rate reduction with ivabradine (Procoralan®, Servier, France) affects aortic compliance and endothelial function in patients with chronic stable coronary artery disease.
Percutaneous coronary intervention (PCI) has become the most common form of coronary revascularization worldwide. Although PCI is a safe procedure, it may have multiple risks including bleeding, coronary dissection, abrupt vessel closure, and myocardial necrosis. It is estimated that approximately 25% of patients undergoing PCI have significant postprocedural creatinine kinase (CK)/creatinine kinase myocardial band (CK-MB) elevations and approximately 50% of patients have significant post-procedural troponin elevations. Initially, it was felt these elevations were simple enzyme leaks with no long-term implications. Now, several studies have demonstrated that periprocedural infarction is associated with short-, intermediate-, and long-term adverse outcomes, most notably mortality. Pretreatment with antiplatelets such as aspirin and clopidogrel play an important role in reducing cardiovascular events (CV events) following PCI. Omega -3 polyunsaturated fatty acids (PUFAs) have antiplatelet effect. It may also improve response to aspirin and clopidogrel in low-response patients. This study is a randomized clinical trial (RCT) evaluating the effect of omega 3 supplement [with 400mg Eicosapentaenoic acid (EPA) and 200mg docosahexanoic acid (DHA)] on short-term (within 30 days) and long-term (after one year) major adverse cardiac events (MACE) in patients undergoing elective PCI. Eighty patients planed to do elective PCI will be categorized into two groups. The first group will be received standard regimen for PCI (aspirin, clopidogrel, and heparin) and the second group will be treated with standard regimen in addition to 3 gram omega 3 (12 hours before PCI). The main end point of the trial was short-term (within 30-days) and long-term (after one year) incidence of MACE (death, myocardial infarction, or unplanned revascularization).
The purpose of this study is to investigate the effect of omega 3 on biomarkers of cardiac necrosis(CKMB and troponin I) and inflammation marker CRP.
This study is a randomized open label study that implies the administration of asprin according to three different regimens. The aims of the study are: - to establish whether coronary artery bypass surgery and / or aortic valve replacement surgery with bioprostheses is associated with changes in the rate of platelet regeneration that can reduce the effectiveness of aspirin administered at a dose of 100mg/die in terms of inhibition of platelet biosynthesis of thromboxane A2. - to determine whether these patients need a different (shorter) interval of administration in order to completely and permanently inhibit the platelet COX-1. The endpoints of this study are: - To evaluate the changes in the levels of TXB2 and 12-HETE in serum at 12 and 24 hours after administration of aspirin and the changes in the levels of 11-dehydro TXB2 urinary 8-iso-PGF2 alpha urinary, 2-3 dinor-6-chetoPGF1 alpha, Verify-NOW Aspirin, platelets crosslinked at 12 and 24 hours after administration of aspirin
