Filter by:The purpose of this study in humans with stable coronary artery disease (CAD) treatable by percutaneous intervention (PCI) is to evaluate the efficacy of Enhanced External Counterpulsation (EECP) with regard to coronary collateral growth.
To evaluate the long-term safety and performance of the DESolve Novolimus Eluting Bioresorbable Coronary Scaffold System
Coronary calcium hampers accurate evaluation of the coronary arteries with coronary computed tomography angiography (CCTA). A novel approach to potentially overcome this limitation is coronary calcium subtraction. The primary hypothesis of the study is: - Coronary calcium subtraction CCTA will improve diagnostic accuracy as compared to conventional CCTA on a per-patient basis
To evaluate long-term safety and performance of the DESyne Novolimus Eluting Coronary Stent System and the DESyne BD Novolimus Eluting Coronary Stent System
The present project is designed to test the hypothesis that arginase contributes to endothelial dysfunction induced by ischemia-reperfusion in patients with coronary artery disease.
Although conventional risk factors for coronary heart disease (CHD) have been identified and routinely used to determine risk for CHD in the general population, a systematic approach to determine population-specific risk for CHD has not been performed prospectively in those with SCI. CHD is a leading cause of death in spinal cord injury, occurring at younger ages than in the able-bodied population. Conventional risk factors for CHD are high serum concentrations of low-density lipoprotein (LDL), low serum concentrations of high-density lipoprotein (HDL), diabetes mellitus (DM), positive smoking history, and positive family history of premature CHD. Coronary Artery calcification (CAC) is a commonly occurring phenomenon that does not necessarily indicate significant obstructive disease. Studies have shown that a strong association exists between coronary calcification and coronary heart disease. The purpose of this study is to compare the CAC scores in persons with SCI with a historical control group of able-bodied persons from a national data base who will be matched for conventional risk factors for coronary artery disease (CAD) and to determine the relationship between CAC scores and conventional and emerging risk factors for CAD. Additionally, postprandial lipemic (elevated levels of lipids following ingestion of food) responses among individuals with SCI and control subjects will be compared, as well as the response of inflammatory markers following a high fat meal. Participants will only be tested once for these parameters.
Investigators will analyzed systolic and diastolic function during and after ischemia induced by percutaneous coronary intervention.Also will be analyzed a local work index during acute ischemia induced by percutaneous coronary intervention.
This study is looking to see if niacin will lessen atherosclerotic plaque inflammation and favorably affect circulating levels of endothelial progenitor cells and microparticles in people with atherosclerotic disease on chronic statin therapy.
Positron emission tomography (PET) scans can be used to evaluate whether parts of the heart muscle are alive but receiving inadequate blood supply. This study involves the use of two radiotracers that will measure whether heart muscle cell are alive and quantify the blood supply to the heart muscle.
To investigate whether instantaneous wave-Free Ratio(iFR)/Fractional Flow Reserve(FFR) guided treatment strategy makes the postulated treatment strategy by Coronary Angiogram(CAG) guide change and to analyze the cost-effectiveness of its dual diagnosis. To investigate difference between SYNTAX score evaluated CAG and functional SYNTAX score evaluated physiological assessment of coronary stenosis and its clinical effectiveness.
