Filter by: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 purpose of this study is to investigate if patients with coronary heart disease have higher risk to develop diabetes mellitus among the following two years. The examination of biomarkers taken from blood and fat issue shall provide which factors could be responsible for development of diabetes mellitus.
The aim of this study is to demonstrate that the combination therapy of aspirin and clopidogrel napadisilate is not inferior to that of aspirin and clopidogrel bisulfate with respect to its effectiveness in inhibiting platelet aggregation, if it is given for four weeks to Coronary Artery Disease (CAD) patients who had been treated with a drug-eluting stent before > 12 months and had remained in a stable condition with a single antiplatelet agent, aspirin.
After a stent procedure, it is common practice to prescribe anti-platelet medication to prevent the blood from clotting. The main objective of this study is to determine if there is a better medication strategy to prevent blood from clotting and at the same time minimising the number of complications. There are two medication strategies: - Study group: Dual anti-platelet therapy (ticagrelor combined with aspirin) for 1 month, and then ticagrelor alone for another 23 months OR - Control group: Standard treatment, being dual anti-platelet therapy (ticagrelor or clopidogrel combined with aspirin) for 12 months, and then aspirin alone indefinitely
The objective of this clinical trial is to evaluate whether an anti-inflammatory medication, pentoxifylline, reduces depressive symptoms and improves artery function. Participants in this trial will be older primary care patients (60 years and up) who are depressed but do not have a history of cardiovascular disease. Half of these patients will receive pentoxifylline, and half will receive placebo. In addition, participants in both arms will receive an evidence-based psychological treatment called Beating the Blues®, which is a computerized, cognitive behavioral treatment program for depression. The investigators will use questionnaires to assess change in depressive symptoms and an ultrasound test to measure change in artery function from pre- to post-treatment. It is hypothesized that patients who receive pentoxifylline will show greater improvements in both depression and artery function than patients who receive placebo.
The purpose of this study is to demonstrate that the strength of agreement between single photon emission computed tomography (SPECT) imaging with regadenoson following inadequate exercise stress testing and SPECT imaging with regadenoson alone is not inferior to the strength of agreement between two sequential regadenoson SPECT images without exercise.
The objective of this clinical trial is to evaluate whether a computerized depression treatment, delivered before the onset of heart disease, reduces the risk of heart disease in the future. Participants in this trial will be primary care patients who are depressed but do not have a history of heart disease. Half of these patients will receive a standard treatment (usual care), and the other half will receive eight weeks of an evidence-based psychological treatment called Beating the Blues®, which is a computerized, cognitive behavioral treatment program for depression. To evaluate change in heart disease risk, the investigators will measure the functioning of the arteries using ultrasound before and after the treatment. It is hypothesized that patients who receive Beating the Blues® will show greater improvements in both depression and artery function than patients who receive standard treatment.
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....
Comparison of the cardioprotective effects and safety of two cardioplegic solutions (solutions used during a cardiac arrest in the heart surgery) in patients undergoing cardiopulmonary bypass for coronary artery bypass surgery.
The present study is designed as a prospective, single centre, open label, observational trial. The study will collect information about the medical care patients receive during their planned procedure(s). No new testing or procedures will be done. Patients elected for hybrid revascularization will be asked their written consent to the use of their personal data. Left internal mammary artery to the Left Anterior Descending Coronary Artery (LIMA-LAD)surgical revascularization will be performed first, followed by percutaneous revascularization of the other vessels in the frame of the same hospitalization. After discharge patients will attend clinic visits at 30 days and 12 months, as per usual clinical practice, and will be contacted by phone at 6 months after procedure. Angiographic follow-up will be performed in symptomatic patients, as clinically indicated.
