NCT ID: NCT03198091 Recruiting - Clinical trials for Coronary Heart Disease

Efficacy of Dun Ye Guan Xin Ning Tablet in Patients With Stable Angina Pectoris

Start date: March 30, 2017
Phase: N/A
Study type: Interventional

This registry is designed to investigate factors affecting the efficacy of Dun Ye Guan Xin Ning tablet on patients with stable angina. The potential hypothesis is that Dun Ye Guan Xin Ning has a better effect on different subgroup patients with certain characteristics.

NCT ID: NCT03195621 Recruiting - Clinical trials for Coronary Artery Disease

Critical Treatment of Coronary Artery Disease

Start date: July 1, 2016
Phase: N/A
Study type: Interventional

Identifying the critical lesion of coronary artery disease and determining the interventional plan are significant for reducing adverse cardiovascular adverse events. The assessment of critical lesion requires the consideration of plaque morphology, tissue composition, and endometrial stress which leading to rupture. In summary, accurate assessment of critical lesions has high application value. In this study, patients with critical coronary artery disease were divided into two groups: an accurate assessment group and a simple assessment group, with the aim to compare the diagnosis and treatment efficiency as well as prognosis, potential cardiovascular risk, possible "excessive" intervention.

NCT ID: NCT03193294 Recruiting - Coronary Disease Clinical Trials

CORonary MICrovascular Angina (CorMicA)

Start date: November 7, 2016
Phase: N/A
Study type: Interventional

Angina is form of chest pain that is due to a lack of blood to the heart muscle. Angina is commonly triggered by stress and exertion, and is a common health problem worldwide. The diagnosis and treatment of angina is usually focused on detection of blockages in heart arteries, and relief of this problem with drugs, stents or bypass surgery. However, about one third of all invasive angiograms that are performed in patients with angina do not reveal any blockages. Many of such patients may have symptoms due to narrowings in the very small micro vessels (too small to be seen on an angiogram). The purpose of this research is to undertake a 'proof-of-concept' clinical trial to gather information as to whether routine tests of small vessel function in the heart might help identify patients with a stable coronary syndrome due to a disorder of coronary function (vasospastic or microvascular angina), and appropriately rule out this problem in patients with normal test results. The diagnostic strategy enables stratification of patient sub-groups to optimized therapy (personalised medicine). Evidence of patient benefits in this study would support the plan for a larger study that would be designed to impact on healthcare costs and patient reported outcome measures (PROMS).

NCT ID: NCT03191708 Recruiting - Clinical trials for Coronary Artery Disease

The FAVOR II China Study

Start date: June 13, 2017
Phase: N/A
Study type: Observational

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. The purpose of the FAVOR II China study is to evaluate the diagnostic accuracy of on-line QFR with FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies between online QFR and online QCA, with FFR as the reference standard.

NCT ID: NCT03189641 Recruiting - Clinical trials for Coronary Artery Disease

Clinical Trial of Cilostazol Eluting Stent System (CES-1) in De Novo Coronary Artery Lesions

Start date: May 31, 2017
Phase: N/A
Study type: Interventional

The purpose of the this trial is to evaluate the clinical safety and efficacy of Cilostazol eluting stent system (CES-1) for the treatment of single de novo lesions in native coronary arteries.

NCT ID: NCT03179592 Recruiting - Clinical trials for Coronary Artery Disease

VOLtage-based Contrast Media AdaptatioN in Coronary Computed Tomography Angiography

Start date: March 22, 2017
Phase: Phase 3
Study type: Interventional

The purpose of this study is to prospectively evaluate the effectiveness of low-volume contrast media (CM) injection protocols adapted to tube voltage in patients undergoing Coronary Computed Tomography Angiography (CCTA).

NCT ID: NCT03179137 Recruiting - Clinical trials for Coronary Artery Disease

Mitochondrial Bioenergetics and Role in Cellular Damage in Ischemic Myocardium

Start date: October 1, 2016
Phase: N/A
Study type: Observational

Cardiac ischemia is a common pathological condition, known to elicit multiple pathological processes at the cellular level. One of the most affected is thought to be cellular metabolism, key for the adequate cardiac function. The aim is to study mitochondrial bioenergetic function, interaction with other cellular systems and influence of several co-morbidities in myocardium of the affected patients.

NCT ID: NCT03178591 Recruiting - Clinical trials for Diabetes Mellitus, Type 2

Effects of DPP4 Inhibitor Versus SGLT2 Inhibitor

Start date: October 2014
Phase: Phase 4
Study type: Interventional

Type 2 diabetes mellitus (type 2 DM) is an important disease with increasing prevalence worldwide. More than 60% of diabetes patients die of CVD. Diabetes is associated with 2-to 4- fold increase in the risk of coronary artery disease (CAD). Diabetes patients with stable ischemic heart disease may have more prevalent of asymptomatic ischemia or silent ischemia due to autonomic neuropathy. Therefore, detection of total myocardial ischemia including both symptomatic and silent ischemia using ambulatory electrocardiogram monitoring may provide better accuracy in ischemic burden and prognosis in diabetes patients. DDP-4 inhibitors have favorable effects on atherosclerotic risk factors beyond glycemic control. Furthermore, DPP-4 inhibitors may have favorable effects on ischemic preconditioning in patients with CAD. For this study we aim to compare the effects of between vildagliptin and Dapagliflozin on ischemic burden defined by total ischemic time, markers of autonomic function, biomarkers of myocardial injury and biomarkers of inflammation.

NCT ID: NCT03175393 Recruiting - Clinical trials for Postprandial Dyslipidemia

Relation Between Postprandial Lipogram and Coronary Artery Disease Severity

Start date: July 1, 2017
Phase: N/A
Study type: Observational

Coronary artery disease (CAD) is usually used to refer to the pathological problem affecting the coronary arteries (usually atherosclerosis) that leads to Coronary Heart disease (CHD) which includes the diagnoses of angina pectoris, MI and silent myocardial ischemia. Despite the mortality for this condition has gradually declined over the last decades in western countries, it still causes about one-third of all deaths in people older than 35 years. Dyslipidemia is very important risk factors of atherosclerosis that is one of the causes leading to cardiovascular disease Despite management of dyslipidemia by controling fasting total plasma cholesterol and LDL cholesterol as these are the best biomarkers for prediction of cardiovascular diseases (CVD) risk. LDL elevation is absent in many patients with atherosclerosis and about 1/3 of cardiac events remains to be unpredicted using this method. Even more, in fasting normolipidemic subjects, increased CVD risk is associated with an exaggerated postprandial lipemic response. Postprandial dyslipidemia is defined as a rise in triglyceride-rich lipoproteins (TRLs), including chylomicron remnants (CMRs) and remnant lipoproteins (RLPs), after eating, has drawn an increasing interest recently because of its association with cardiovascular events. Chylomicron remnants (CMRs) have been shown to penetrate the artery wall and to be retained within the intima. Endothelial dysfunction is an initial process of atherogenesis and it contributes to the pathogenesis of CHD. Postprandial hyperlipidemia (postprandial hypertriglyceridemia) is involved in the production of proinflammatory cytokines, recruitment of neutrophils, and generation of oxidative stress, resulting in endothelial dysfunction
