Active clinical trials for "Coronary Artery Disease"

To assess the feasibility of coronary computed tomography angiography (CTA) and fractional flow reserve derived from CTA (FFRCT) to replace invasive coronary angiography (ICA) as a surgical guidance method for planning and execution of coronary artery bypass graft (CABG) in patients with 3-vessel disease with or without left main disease. The FASTTRACK CABG study is an investigator-initiated single-arm, multicentre, prospective, proof-of-concept, and first-in-man study with feasibility and safety analysis. Surgical revascularization strategy and treatment planning will be solely based on coronary CTA and FFRCT without knowledge of the anatomy defined otherwise by ICA that will be viewed and analyzed only by the conventional heart team. Clinical follow-up visit including coronary CTA will be performed 30 days after CABG in order to assess graft patency and adequacy of the revascularization with respect to the surgical planning based on non-invasive imaging with functional assessment and compared to ICA. Primary feasibility endpoint is CABG planning and execution solely based on coronary CTA in 114 patients. Primary safety endpoint based on 30-day coronary CTA is graft assessment either at the ostium, in the shaft or at the anastomoses of each individual graft either single or sequential. The FASTTRACK CABG study is the first study to assess safety and feasibility of planning and execution of surgical revascularization in patients with complex coronary artery disease, solely based on coronary CTA combined with FFRCT.

This study is designed to verify the safety and efficacy of Lepu® NeoVas™ Bioabsorbable Coronary Artery Rapamycin-eluting Stent System combined with different antiplatelet therapies in the treatment of coronary heart disease.

To evaluate the safety and effectiveness of percutaneous coronary intervention using a 7-French(Fr) thin wall sheath via the snuffbox approach

In patients with vasospasm or with negative remodeling, various vasodilator drugs used during coronary angiography can dilate the diameter of the reference vessel to measure the exact vessel size. In particular, nitrates are well known to induce pharmacological vasodilatory effects through vascular smooth muscle relaxation In actual clinical practice, it has been reported that when oral or spray-type nitrate preparations are administered to coronary artery stenosis lesions, the diameter of the reference vessel expands by about 10% compared to the existing vessel diameter. This may enable larger stenting in coronary artery stenosis lesions. Although many patients with vascular stenosis are accompanied by vasospasm and voice remodeling, in actual clinical practice, administration of vasodilators is only used in a small number of patients at the discretion of the surgeon. Nitrate vasodilators administered during coronary angiography are low-dose and short-acting drugs, and although a small number of patients may experience side effects such as short-term lowering of blood pressure, no serious side effects are reported . On this background, this study is to evaluate whether there is a difference in the diameter of the Ultimaster® stent treated with the conventional method compared to the maximally dilated coronary artery, and to evaluate the stability and effectiveness after the procedure.

The novolimus-eluting DynamX bioadaptor system is composed of 71 µm cobalt-chromium sinusoidal rings connected to each other axially by three S-links Each ring contains three uncaging elements that are positioned at equal distance in low stress regions of struts oriented in a helical configuration along the length of the bioadaptor which remain intact after uncaging. The uncaging elements consist of three separable junctions per ring held together by a 6 µm polymer coating that is resorbed over six months, allowing uncaging of the vessel and adaptive remodeling. Previous study showed the DynamX biodaptor is safe and effective treating in de novo coronary lesion. It also increased of vessel and device area while maintain in the mean lumen area after one year follow-up. However, the unchanging effect of Dynamx bioadaptor on coronary geometry change remained unknown. The present randomized control study is designed to investigate the differences of dynamic coronary artery geometry changes evaluated by coronary computed tomography angiography after DynamX Bioadaptor and permanent metallic DES implantation.

Single-centre prospective study to characterize causes of dyspnea in stable patients with coronary artery disease and evaluate the possibility to determine the cause of dyspnea before in-depth examination.

Atherosclerosis is a disease of the arteries and is the result of various factors such as high blood cholesterol or diabetes, which lead to accumulations of fats, cells, and calcium deposits (i.e. plaques). It has been shown that people with a rapid increase in the amount of calcium deposits have a higher risk for stroke and heart attack than people with a decreased amount. Previous scientific research has shown that a protein called Matrix Gla Protein plays an important role in the prevention of calcification. This protein works well only if there is enough Vitamin K in the blood vessels. In a large human studies, it has been shown that especially MK-7 (a form of Vitamin K2) is best absorbed by blood vessels. Moreover, studies suggest positive effects of vitamin D (especially D3) on vitamin K-dependent metabolism. Over the last years, fluorine-18 sodium fluoride (18F-NaF) positron emission tomography (PET) emerged as a reliable clinical imaging tool able to detect micro-calcification in the blood vessels. Therefore, the present study will use 18F-NaF PET in combination with magnetic resonance imaging (MRI) to assess the influence of vitamin K and D supplementation in the development of arterial micro-calcification in the context of atherosclerosis. The present study would like to confirm that MK-7 and vitamin D3 supplementation induces a significant reduction in the degree of micro-calcification from carotid artery disease patients, when comparing to a placebo, after 3 months. This will be a prospective double blind randomised controlled feasibility study, in which one group will receive a MK-7 and vitamin D3 supplementation compared to a control group receiving a placebo.

To determine whether hemodynamic support combining VA-ECMO with IABP could mitigate the rates of Major Adverse Cardiovascular and Cerebrovascular Events (MACCEs), compared with IABP support alone, in patients undergoing elective and high-risk PCI.

The registry follows the ESC/EACTS guideline and further investigates the clinical performance and short-term safety of RMS (Resorbable Magnesium Scaffolds) in a real world setting within the scope of its intended use without further (medical related) exclusion criteria according to their respective instructions for use (IFU).

CAD is a challenging affliction which has a high annual morbidity rate in China and the world. Severe CAD may lead to compromised cardiac function, decreased exertional capacity and poor quality of life (QOL). The most common treatment for CAD is medication, percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). However, some patients had long-term of history with complex severe artery lesions, they are not candidate for redo interventional therapy. Cardiac shock wave therapy (CSWT) is an exploring therapy used globally for CAD patients, which is known for its safety, non-invasiveness and effectiveness.The previous RCT from the investigators' team has already finished, and results are in submission processing. This is a prospective, single arm, observational study design. CAD patients will be enrolled consecutively. The entire treatment period will last 3 months with 9 sessions. Outcomes are assessed as efficacy outcomes and safety outcomes. Efficacy outcomes include symptom (CCS score, NYHA classification, nitroglycerin dosage, SAQ questionnaire), exertional capacity (6MWT), quality of life (SF-36 questionnaire) and imaging evaluation (myocardial perfusion imaging and echocardiography). Safety outcome include the change of serum TNT, CKMB, BNP and adverse event (AE) occurrence. The participants will be followed up at 13th week, 6th months and 12th months.
