Active clinical trials for "Coronary Disease"

The purpose of this study is to conduct a single-center, randomized, open-label, controlled, dose-escalating, parallel-group study, evaluating the effects and change of endothelial function and gut microbiota after berberine administration in patients with stable coronary artery disease who are at > 8 but ≤ 40 weeks after elective percutaneous coronary intervention

This study is a randomized, double-blind, placebo-controlled, parallel clinical trial in Chinese population with stable angina pectoris. The purpose is to determine the efficacy and safety of Yangxin Shengmai Granules in the treatment of stable angina pectoris.

The aim of study is to examine the relationship between lipid subfractions, inflammation and structural-functional properties of the arterial wall in patients with premature coronary heart disease, to study genetic polymorphisms that determine lipid subfractions concentration on the functional and morphological properties of the arterial vascular wall in patients with early coronary heart disease, to study the effect of alirocumab and evolocumab on lipid subfractions, inflammation and structural-functional properties of arterial wall in patients with early coronary atherosclerosis and to study the influence of NOS-3 gene expression on the functional and morphological properties of the arterial vascular wall in the same patients. Impaired blood fat metabolism and chronic inflammation are intertwined as possible causes of atherosclerosis. Lipoprotein (a) (Lp (a)) is an important risk factor for coronary heart disease and a prognostic predictor in patients after myocardial infarction, but recent research suggests that subtilisin-kexin convertase type 9 (PCSK9) inhibitors are the only drugs that significantly reduce serum Lp (a) concentration. However, there are no data on the relationship between Lp (a) values and polymorphisms for Lp (a), indicators of inflammation and impaired arterial function, and response to treatment with various PCSK9 inhibitors in patients with early coronary heart disease.

The purposes of this study is to standardize the process of formulating exercise prescriptions for coronary heart disease（CHD）, verify the safety and effectiveness of exercise prescriptions, and establish a database of exercise prescriptions for CHD, with a view to providing new solutions for cardiac rehabilitation.

A randomized, double-blind, placebo trial was adopted, and cardiopulmonary exercise load test (CPET) was used to detect peak oxygen uptake (PeakVO2) and exercise metabolic equivalent (METs) to confirm the clinical effect of Zhenyuan capsule on improving cardiopulmonary endurance in patients with coronary heart disease of qi deficiency and blood stasis.

E5TION will evaluate the efficacy, safety and tolerability of tailored two regimens (prasugrel 5mg/d vs. ticagrelor 60mg bid) in high-risk patients undergoing PCI (CHIP: COmplex and Higher-Risk Indicated PCI/PatieNts).

Distal radial access (dTRA) represents a novel site for radial artery access in interventional cardiology, there is little data compare dTRA with conventional radial access (cTRA) in a randomized manner. It aims to randomly compare between the new distal radial access via the snuffbox and the conventional radial access for percutaneous coronary intervention (PCI) and angioplasty procedures. The objectives of comparing both procedures are to analyze the frequency of complications in terms of occlusion, arterial spasm, hematoma, and to weigh accesses effectiveness in terms of time and attempts to puncture, crossover rate, procedure duration, hemostasis time. Candidates for coronary angiography are being randomized into the interventional group to undergo the angiography through the distal radial artery as the access site, or the control group accessing through the radial artery. Procedural and post procedural outcomes and complications are being reported while patients are in hospital. All patients undergo doppler ultrasonography within 24 hours before and after the procedure, 4 weeks after procedure.

The present study aims to compare a planned angiographic control (PAC) follow-up strategy vs. conservative management for patients treated with drug-eluting stents on unprotected left main artery in a prospective, randomized setting. PAC will be performed by coronary computed tomography (CCT), to avoid the limitations of the invasive coronary angiography which is usually employed to perform PAC. The superiority of a PAC-based approach will be tested on a hard clinical end-point such as the incidence of major adverse cardiovascular events. The investigators will also assess the performance of CCT as a tool to perform PAC.

The utilization of everolimus-eluting coronary stents in a coronary artery diseases is effective in reducing both repeat revascularization and major adverse cardiac events within two year follow-up. To evaluate the procedural, short and long term clinical outcomes of multiple everolimus-eluting coronary stent implantation in long (>30mm) coronary lesions.

The purpose of this study is to use a high-resolution intracoronary imaging modality, called optical coherence tomography (OCT) to examine two different types of coronary artery stents used to treat patients with coronary artery disease.
