Filter by:A prospective, multicenter, 1:1 randomized, investigator initiated study. Goal of this study is to examine the safety of uninterrupted periprocedural NOAC use.
The study will investigate the influencing factors of exercise adherence of home-based cardiac rehabilitation in patients with coronary artery disease.
It aims to compare the effects of a professional -led support programme using a mobile application versus telephone advice on clients at risk of coronary heart disease. A multi-centre, single-blinded, randomized controlled trial will be conducted. 168 Clients who are at risk of coronary heart disease (CHD), able to use a smart phone will be randomized into the App Support group (App group) or the Nursing Telephone advice (NTA) group . All participants will receive same nursing educational briefing related to CHD. The App Group will additional receive an app use to support their self care whereas the NTA group will receive nursing telephone advice for 20 minutes monthly. Health outcomes will be collected at baseline (T0), 1 months (T1), 3 months (T2). Data analysis will be conducted using a Generalized Estimating Equations model to assess differential changes in all outcome variables.
Prospective, 1:1 randomized, controlled, multicenter trial to assess effectiveness and safety of Intravascular Lithotripsy (IVL) compared to Rotational Atherectomy (RA) treatment in calcified coronary lesions
This study was planned to determine the effect of hand reflexology on anxiety and vital signs in patients undergoing coronary angiography. In the G-power analysis conducted to determine the sample of the study, experiment and control were calculated as 60 in total, with the sample number of both groups being 30. Since the study is a single-blind randomized clinical trial, in order to determine the randomization , a box with the names of the patients determined according to the participation criteria will be determined by the selection of the healthcare personnel responsible for the service, and the experimental and control groups. "Demographic Data Form" , "Distress Thermometer". "State Anxiety Inventory" , "Vital Signs Form" and Visual Analog Scale will be used to collect research data.
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.
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 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.
The trial aims to evaluate the long-term clinical outcome of the DCB-only technique is non-inferior to the provisional T stenting with DES in the patients who have 'true' bifurcation lesions.
The investigators evaluate the effects of intracoronary and intravenous administration of nicorandil on cardiac sympathetic nerve activity and distribution in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention
