Active clinical trials for "Coronary Artery Disease"

The prediction of extent and risk profile of coronary atherosclerosis based on clinical evaluation and non-invasive techniques. Detailed analysis of plaque volume, plaque composition, risk plaque features and shear stress (WSS) changes during lipid lowering therapy (rosuvastatin 40mg) from 3D vessel reconstruction. Prediction of changes in coronary arteries based on changes in non-invasive examinations. Examination of WSS influence on atherosclerosis development and changes of WSS during lipid lowering therapy.

The proposed study is to validate a new non-invasive imaging technique for evaluation of cardiac microciculation in coronary artery disease with a comparison with validated technique invasive, which is measure of index of myocardial resistance.

To treat patients with stable coronary artery disease, elective percutaneous coronary intervention (PCI) will be performed with the use of an everolimus-eluting cobalt- chromium stent (everolimus-eluting stent: EES, Xience Prime, Xpedition), which is the current standard drug-eluting stent (DES). Vascular responses at the site of stent placement will be evaluated by optical coherence tomography (OCT) at 1 or 3 months and at 12 months after stent placement, along with observation of changes over time in the target vessel. The relationships between OCT findings and the time course of platelet aggregation and between OCT findings and the occurrence of major cardio- cerebrovascular events will also be elucidated.

This pilot clinical trial studies computed tomography (CT) scans and biomarker analysis in diagnosing coronary artery disease (CAD) in patients who have undergone a stem cell transplant but have no symptoms of CAD. CAD is a disease in which there is a narrowing or blockage of the coronary arteries (blood vessels that carry blood and oxygen to the heart) and patients who have undergone a stem cell transplant are at an especially high risk for CAD. A CT scan involves a series of detailed pictures of areas inside the body taken from different angles. The pictures are created by a computer linked to an x-ray machine. Studying samples of blood from patients who have undergone a stem cell transplant in the laboratory may help doctors identify and learn more about biomarkers related to CAD. Using a CT scan in combination with biomarker analysis may be a better and less-invasive way to diagnose CAD.

The American College of Cardiology/American Heart Association guidelines place symptomatic severe Aortic Stenosis as a class I indication for aortic valve replacement. With the recently approved Edwards-Sapien TAVR device and the ongoing investigations using the CoreValve TAVR device, patients ineligible or at high risk for open-heart surgery are now eligible to undergo TAVR. Patients selected for TAVR undergo an EKG-gated cardiac Multislice CTA to evaluate aortic valve anatomy and aortic root dimensions for device sizing, as well as coronary angiography to define coronary anatomy. Both tests utilize contrast media to visualize anatomy, which may result in contrast-induced nephropathy in anywhere from 7.5% to more than 50% of patients depending on associated clinical risk factors. There is a need to consolidate this pre-operative testing whenever possible, and with real-time 3-dimensional visualization of aortic valve and root anatomy using DynaCT cardiac acquisition in the cath lab angiography suite during the coronary angiography, there may be a benefit with reduced contrast load (20 to 35cc for DynaCT, 100cc for CTA). We would like to make a comparison of aortic valve and root measurements using CTA and DynaCT to affirm the accuracy of DynaCT vs the CTA gold standard.

Investigators at the Biomedical Imaging Research Institute (BIRI) at Cedars-Sinai Medical Center have developed a Magnetic Resonance Imaging (MRI) method for imaging coronary arteries using slow-infusion, contrast-enhanced data acquisition. This method allows faster data acquisition and better spatial resolution. Specific aims of this study are to: compare coronary artery imaging with and without contrast media on both healthy subjects and patients; assess the accuracy of coronary MRI in detecting coronary artery disease as compared to conventional x-ray angiography Researchers hypothesize that contrast-enhanced MRI will improve the delineation of coronary arteries over non-contrast-enhanced MRI and that optimized, contrast-enhanced coronary MRI technique will accurately detect coronary artery disease (CAD) as compared to conventional x-ray angiography.

Gingival inflammation has been associated with cardiovascular diseases, including heart attack and stroke, because of elevation of blood risk markers such as cholesterol, glucose and C reactive protein. The treatment of gingival diseases decreases the concentration of these risk factors in the blood of cardiovascular patients.

In this study, typical cases of blood stasis syndrome of coronary heart disease are selected, by using microRNA chip, cDNA microarray and other bioinformatics technologies to filter and verify related miRNA and its target gene of Coronary Heart disease. Meanwhile, intervene by Xuesaitong soft capsules to investigate related miRNA and its target gene of Coronary Heart disease.

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.

Cardiovascular complications account for the highest mortality in type 2 diabetic patients, mainly due to coronary artery disease (CAD). Most of the attention in treating CAD in type 2 diabetes is understandably directed toward treating coronary artery conditions. However there are other treatable culprits in these patients. Left ventricular hypertrophy (LVH) is widespread in type 2 diabetic patients with CAD, even in the absence of hypertension. It is a strong predictor of cardiovascular events and all-cause mortality. Regression of LVH has been associated with an improved prognosis, independent of change in blood pressure (BP). Therefore, cardiovascular events and mortality in type 2 diabetes with CAD might will be reduced if the investigators can find novel therapies to regress LVH. Alpha-lipoic acid reduces oxidative stress which then regresses LVH. Alpha-lipoic acid can improve endothelial function in diabetic conditions. Hence, the main aim of this study was to assess whether alpha-lipoic acid could regress LVM in type 2 diabetic patients with CAD.
