Efficacy and Saftey Study of 99mTc-ECDG in the Evaluation of Coronary Artery Disease (CAD)
Coronary Artery DiseaseThis study will compare how well a new radiolabeled imaging agent ECDG compares to the current testing for coronary artery disease (radiolabeled Sestamibi) during a rest and stress cardiac test as documented from results of a coronary angiogram (if performed).

Multiple Electrode Aggregometry & Clopidogrel Resistance
Type 2 Diabetes Mellitus (T2DM)Coronary Artery Disease (CAD)1 moreAntiplatelet therapy with aspirin-clopidogrel reduces the risk of cardiovascular episodes after percutaneous coronary intervention (PCI) in patients with acute coronary syndromes. However, a significant number of patients experience recurrent events while on such therapy. The individual response to dual antiplatelet therapy is not uniform, and consistent findings across multiple investigations support the association between a lower degree of platelet inhibition, high on-treatment platelet reactivity, and the occurrence of atherothrombotic events [1, 2]. Particularly in diabetic patients, clopidogrel resistance is more prevalent compared with non-diabetics [3,4], which seems to contribute to the increased atherothrombotic risk in these patients compared with those without diabetes mellitus (DM) [5]. A number of platelet function instruments have now become available that are simple to use and can be utilized as point-of-care (POC) instruments in order to monitor antiplatelet therapy and potentially assess the risk of a recurrent event [6].

Statin for Depression in Patients Undergoing Coronary Artery Bypass Graft
Coronary Heart DiseaseDepression is frequently observed in patients with coronary heart disease (CHD) and represents a significant risk factor for major cardiovascular events. Previous study has proved that high sensitive C-reactive protein (hsCRP) was an independent predictor for depression in CABG patients at 6 months after bypass surgery. Statins can effectively reduce the blood levels of hsCRP. This study aim to examine whether statins can improve the prognosis of depressive patients undergoing coronary artery bypass surgery through reducing the levels of hsCRP.

Perfusion CT Registry
Coronary Artery DiseaseThe purpose of this study is to determine whether coronary perfusion computed tomography is effective in the treatment of coronary artery disease.

Assessment of Natural Bypasses in the Lower Limb
Peripheral CollateralsArteriogenesis1 moreConcerning the promotion of peripheral collateral growth, clinical studies investigating new therapeutic strategies have used imprecise assessment methods and therefore determined only "weak" endpoints. In contrast to the coronary circulation, there is currently no gold standard available to document successful promotion of collateral growth in patients suffering from peripheral artery disease. Therefore, the purpose of this study is to evaluate a new invasive method to quantify arterial collateral flow in the lower extremity in patients undergoing elective coronary angiography.

Drug Eluting Balloon Versus Drug Eluting Stent in PCI
Coronary Artery DiseaseDrug eluting balloons (DEB) have been developed to overcome the limitations of drug eluting stent (DES), but clinical results of different studies about DEB are not consistent. Thus, we planned a meta-analysis to compare outcomes of DEB and DES in coronary artery disease (CAD).

A Trial of Stress Reduction in the Secondary Prevention of Coronary Heart Disease in Blacks
Coronary Artery DiseaseThe overall hypothesis of this study is that a cardiac rehabilitation program with meditation will be more effective than cardiac rehabilitation alone in improving blood flow through the diseased coronary arteries in African Americans. For this purpose, 56 African American men and women with coronary heart disease will be randomly assigned either to standard cardiac rehabilitation plus the Transcendental Meditation program or to standard cardiac rehabilitation alone. The treatment period will be 12 weeks in length.

Mainz Registry of Flow-mediated Constriction
Coronary Artery DiseaseThe goal of the flow-mediated constriction/ FMC-registry is to investigate whether the measurement of endothelial function using flow-mediated dilation and flow-mediated constriction provides on the presence of coronary atherosclerosis and on the prognosis of patients undergoing coronary angiography.

Prevalence of Allergic Diseases and Atopy in Subjects With Coronary Artery Disease
Coronary Artery DiseaseAllergy1 moreThe purpose of this study is to estimate the prevalence of allergic diseases and atopy among patients with angiographically confirmed coronary artery disease as well as to assess levels of serum allergic inflammation markers in this population.

ABSORB: Postmarketing Surveillance Registry to Monitor the Everolimus-eluting Bioresorbable Vascular...
Cardiovascular DiseasesCoronary Artery Disease8 moreThe registry aims to evaluate the safety, performance and efficacy of the Everolimus-eluting bioresorbable vascular scaffold (BVS) system in patients with de novo native coronary artery lesions in all-day clinical practice.
