A Case Control Study of Resveratrol Effects in Coronary Artery Disease Patients With Metabolic Syndrome...

Metabolic SyndromeCoronary Artery Disease

The aim of this study is to explore the role of Canonical β-catenin/Wnt and forkhead box O (FOXO) pathways by means of investigating their target genes in coronary artery disease (CAD) pathogenesis and to examine the effects of resveratrol (RES) on these pathways in CAD patients.

Physiological Study of Human Cholesterol Metabolism and Excretion

Coronary Heart DiseaseCardiovascular Disease2 more

The underlying hypothesis is that whole body cholesterol - including cholesterol present in tissues that cannot be measured by standard blood tests - is related to heart disease risk. Endogenous cholesterol will be labeled with an intravenous infusion of one type of cholesterol tracer and dietary cholesterol will be labeled with another. These tracers will be used to measure how fast cholesterol is synthesized and excreted using mass spectrometry to distinguish the tracers. Data will be related to circulating biomarkers (blood tests) and to the thickness of the lining of the carotid artery. The effect of the drug ezetimibe on these processes will also be determined. Successful completion of this study will give us more knowledge about cholesterol metabolism that may be useful in designing new drugs and treatments for patients with heart disease, especially those that are already receiving maximum amounts of current medications.

Effect of PADMA 28 on Endothelial Function, Autonomic Nervous System and Biomarkers in Patients...

Coronary Artery Disease

This randomized, placebo-controlled, double-blinded trial investigates the effect of a 6 week intake of PADMA 28 on the endothelial function, biomarkers and the autonomic nervous systems in patients with coronary artery disease. The investigators hypothesize that PADMA 28 has a beneficial effect on endothelial function, arterial stiffness, the autonomic nervous systen and the blood inflammatory markers in patients with coronary artery disease compared to placebo treatment.

A Study to Determine the Effect of Bi-Ventricular Pacing on Cardiac Hemodynamics After Coronary...

Coronary Disease

The purpose of this study is to determine, using echocardiography, whether bi-ventricular pacing improves the contractile force by resynchronizing both ventricles, thereby improving and/or correcting the paradoxical septal movement. Primary Hypothesis: Bi-ventricular pacing post cardiac surgery will result in at least a 10% increase in cardiac index (CI) as compared with standard atrio-right ventricular pacing. Secondary Hypothesis: Bi-ventricular pacing post cardiac surgery will result in at least a 10% increase in cardiac index (CI) as compared with atrio-left ventricular pacing and right atrium pacing.

Atrial Fibrillation and Ischemic Events With Rivaroxaban in Patients With Stable Coronary Artery...

Atrial Fibrillation

In patients with atrial fibrillation (AF) complicated with coronary artery disease (CAD), antiplatelet drugs are commonly used for the prevention of recurrence of stent thrombosis and cardiovascular events in combination with anticoagulant drugs. Based on the observations that the incidence of hemorrhagic complications increased when an antiplatelet drug was administered in combination with vitamin K antagonist (VKA), the guidelines for antithrombotic therapy after PCI in the US and EU recommend that DAPT (dual anti-platelets therapy) should be used in AF-complicated CAD patients for as short a time as possible following single anti-platelet and VKA, and that monotherapy with VKA should be started from one year after PCI. In 2013 the European Heart Rhythm Association (EHRA) published the guidelines for the use of NOACs in NVAF patients, which state that NOACs may have advantage to VKAs in terms of anti-thrombotic effects in NVAF patients undergoing PCI. However, no clinical evidence has ever been generated to reveal the efficacy and safety of mono-drug therapy with a NOACs in stable CAD patients one year or more after PCI. AFIRE study is planned to evaluate the efficacy and safety of mono-drug therapy with a rivaroxaban in stable CAD patients. Among NOACs, rivaroxaban was chosen because of the evidence in Japanese patients and the results of a sub-analysis of ROCKET AF suggesting that rivaroxaban is more effective than VKA in reducing the incidence of myocardial infarction (MI).

Safety and Efficacy of Low-dose Ticagrelor in Chinese Patients With Stable Coronary Artery Disease...

Coronary Artery Disease

Ticagrelor is an oral, reversibly-binding, direct-acting P2Y12 receptor antagonist used clinically for the prevention of atherothrombotic events in patients with acute coronary syndromes (ACS). Guideline recommendations on the use of dual antiplatelet therapy (DAPT) have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for patients who have an ACS with or without ST-segment elevation. However, few East Asian patients (or those of East Asian descent) have been included in these trials to assess the use of these drugs. In Korea and Japan, it has been reported that low doses of ticagrelor might have a more potent inhibition of platelet aggregation (IPA) than clopidogrel (75 mg once daily) in healthy subjects and patients with stable coronary artery disease, respectively. But it is still not clear whether a low dose of ticagrelor is superior to clopidogrel in a large population of Chinese ACS patients. A recent study on pharmacokinetics and tolerability of ticagrelor has found that maximum plasma concentration and area under the plasma concentration-time curve of ticagrelor (90 mg twice daily) and its active metabolite (AR-C124910XX) tended to be approximately 40% higher in healthy Chinese volunteers compared with Caucasian subjects. This data also suggested that a low dose of ticagrelor might be more appropriate for Chinese ACS patients. In view of a large diurnal variation with a single daily dose, a lower dose twice daily may be a better choice for Chinese patients. Therefore, the investigators performed this randomized, single-blind, crossover clinical trial to observe the efficacy and safety of low-dose ticagrelor (22.5 mg twice daily) in comparison to clopidogrel (75mg once daily) in Chinese patients with stable coronary artery disease.

Effect of External Counter Pulsation on Coronary Artery Disease

Stable Chronic AnginaCoronary Artery Disease

Coronary artery disease (CAD) is prevalent worldwide and the leading cause of mortality of citizens, external counter pulsation (ECP) has been elucidated that it may release angina symptoms and improve the prognosis of CAD, however, no multi-center control clinical study has been reported for further recommendation. The aim of this study is to evaluate the effect of ECP on CAD. To address this assumption, investigators enroll participants with stable CAD and randomize them into control or ECP group, the ECP intervention will be carried out with a standard protocol which involves 35 one-hour sessions (5 days a week) for continuous 7 weeks, and the follow-up will last for 1 year. The primary endpoint is the 1-year composite cardiovascular events (CCE), secondary endpoints include frequency of angina pectoris, heart function, biomarkers of arteriosclerosis, exercise tolerance and endothelial function.

efficAcy and Safety of Home-baSed Cardiac rehabIlitation in ChineSe Revascularized patienTs

Coronary Artery Disease

Home-based CR (HBCR) was reported to improve the clinical outcomes of coronary artery disease (CAD) patients. There is no data published to investigate whether HBCR is also effective for Chinese CAD patients who have been revascularized. This trial was designed to investigate the safety and efficacy of CR program at home for Chinese patients who underwent PCI (Percutaneous Coronary Intervention) procedure. This is a multicenter, randomized, controlled and observational study.
