Filter by:The purpose of this study is to evaluate the efficacy of predilation with paclitaxel-eluting balloon and bare metal stent implantation VS conventional balloon and drug-eluting stent implantation in terms of restenosis
Personalized treatment approaches and antiplatelet drug choice have been proposed to optimize safety of coronary stenting by reducing heart attacks and repeat interventions while simultaneously minimizing adverse bleeding events. This study compares the efficacy of two laboratory guided treatment algorithms to personalize antiplatelet medication choice after coronary stenting
Registry of cilotax stent(Dual drug eluting stent) implantation for CAD patients
This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES).
The ideal grafts for the right coronary artery system in coronary artery bypass surgery remain controversial. The objective of this study is to compare the long-term patency of a right gastroepiploic artery and a saphenous vein graft used for revascularization of the right coronary artery system in off pump coronary artery bypass surgery and to analyze the long-term clinical outcomes. Total 224 patients will be enrolled according to the randomization protocol. Check list 1. Laboratories 2. Quantitative coronary analysis (preoperative) 3. Major adverse cardiac and cerebrovascular event 4. coronary CT (coronary angiography if needed) at discharge, 1, 5, 10 years postoperatively 5. Echocardiogram 5. Cardiac enzyme
Background: - Bone marrow stromal stem cells (also known as mesenchymal stem cells) have been isolated and are found to make large amounts of growth factors. Because they make growth factors, these cells can help re-grow tissue and encourage repair of damaged tissue. Tests on damaged heart muscle suggest that injecting these cells directly into damaged heart muscle can improve heart function. Researchers want to give stem cells to people who are having open heart surgery to see if they can help to repair heart muscle damage. Objectives: - To test the safety and effectiveness of bone marrow stromal stem cell injections given during heart surgery to treat heart muscle damage. Eligibility: - Individuals at least 18 years of age who are scheduled to have open heart surgery for heart artery or vein blockages. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will also be collected. - Participants will have bone marrow taken from both hip bones about 3 weeks before the heart surgery. - During the surgery, the stromal stem cells collected from the bone marrow will be given into the damaged portion of the heart muscle. The rest of the heart surgery will be performed according to standard procedures. - After the surgery, participants will be monitored for complications from the stromal stem cells. - Participants will have heart function tests to see if the stromal stem cell treatments were effective....
The purpose of this study is to determine whether a single intracoronary infusion of Ad5FGF-4, delivered during induced transient ischemia, is effective in improving myocardial perfusion, angina functional class, patient symptoms, and quality of life. Short-term (8 weeks) and long-term (12 month) safety of Ad5FGF-4 will also be evaluated. The primary endpoint is change in adenosine triphosphate (ATP) stress SPECT reperfusion defect size.
The objective of this study is to identify proteomic inflammatory biomarkers to determine if there are differences in the biomarkers in patients who are treated using the CorMatrix ECM implant to close the pericardium and the patients whose pericardium is left open (the current standard of care).
The purpose of this study is to evaluate patency rates of the eSVS Mesh Saphenous Vein Graph (SVG) and control SVG at six and twenty-four months via coronary angiography and analyses of Duplex Sonography Results and coronary angiography and major cardiovascular or cerebrovascular event (MACCE)-Rate as well as analysis of preoperative great saphenous vein (GSV) duplex sonography and intra-operative GSV harvesting findings and procedure.
Coronary artery disease results in narrowing of the blood vessels supplying oxygenated blood to the heart muscle. Diagnosis in patients with symptoms of chest pain is now quickly done with CT coronary angiography. This x-ray test can show narrowed blood vessels but has limited ability to predict the severity of the narrowings in some cases. We have described a new approach using PET exercise 18F-FDG imaging as a method to image areas of heart muscle not getting enough blood during exercise stress. The 18F-FDG images are co-registered with the CT anatomy from the CTA to provide direct evidence of the consequences of the narrowing.
