The primary objective of this study is to determine the feasibility and safety of receiving intravascular hypothermia treatment for patients experiencing endovascular treatment after acute ischemic stroke(AIS) due to a large vessel occlusion.
This clinical trial aims to learn whether blood pressure (BP) guided by individualized cerebral autoregulation (CA) is safe and provides a better prognosis than a fixed target in patients with ischemic stroke after endovascular therapy. The BP of participants will be managed at least 48 hours after revascularization. Researchers will compare the CA-guided BP group with the fixed target BP group to mainly see if individualized BP could help more patients to have their neurological function improved at seven days.
To investigate the evolution of imaging appearances and cognitive function of Moyamoya disease (MMD) and to establish a prognosis evaluation system based on imaging biomarkers in MMD. The study may be helpful to optimize and improve the diagnosis and pretreatment assessment of MMD, and provide an important theoretical supplement to the existing guidelines for the management of MMD.
This registry will include consecutive patients presenting with at least one chronic total occlusion on coronary angiogram who will be treated by percutaneous coronary intervention in our center. All patients will undergo a non-invasive assessment for myocardial ischemia/viability using cardiac magnetic resonance (CMR) prior to revascularization therapy. Follow up CMR will be repeated in all participants after three months and one year. Additionally, clinical outcomes and quality of life will be evaluated at baseline and at follow-up. Primary objective of this study is to investigate the the reduction in ischemia (as evaluated by follow-up CMR) and the severity of angina according to clinical evaluation (including Seattle Angina Questionnaires [SAQ], Canadian Class Score[CCS] and 6-mins walking test).
A short description, 5000 characters Ischemic cardiomyopathy related to coronary artery disease is currently the leading cause of heart failure. When it is responsible for heart failure, the coronary artery disease likely involves 2 or 3 vessels. Percutaneous coronary angioplasty, which is the other available technique for coronary revascularization, has never been evaluated in this indication. The results of retrospective registries studying the strategy for multivessel revascularization in patients with heart failure are inconsistent and no randomized study has been performed so far. Currently, ESC guidelines recommends to perform coronary-artery bypass grafting (IB) or percutaneous coronary intervention (IIa C) with the acknowledgement that percutaneous coronary intervention has never been properly evaluated in this setting. However, it has been previously demonstrated that left ventricle dysfunction significantly increases mortality and morbidity during and after cardiac surgery (3-10% mortality when LVEF is ≤30%). Moreover, the technical progresses in stent development and manufacturing have led to a dramatic decrease in the incidence of stent thrombosis and in-stent restenosis. Therefore, we hypothesize that percutaneous coronary angioplasty may be an attractive strategy for revascularization in patients with multi-vessel disease and left ventricle dysfunction, who are at high risk of surgical complication. Thus, we aim to test the hypothesis that percutaneous coronary intervention is non-inferior to coronary-artery bypass grafting for revascularization in patients with multivessel disease and left ventricle dysfunction. The main objective is to demonstrate that percutaneous coronary angioplasty is non-inferior to coronary-artery bypass grafting for multivessel revascularization in patients with left ventricular dysfunction on major cardiac and cerebrovascular events (MACCE). Method:A Prospective Randomized Open label, Blinded Endpoint, parallel-group, active controlled, non-inferiority, multicenter trial.
The purpose of the study is to assess the safety and efficacy of the BioFreedom Ultra stent for treatment of STEMI patients. Besides, in patients who are clinically indicated for a stage procedure, Investigators aim to assess the angiographic and endovascular healing of BioFreedom Ultra stent at one month This is a prospective, single center, post marketing registry. Investigators aim to recruit 50 patients. All enrolled patients will be followed up for 12 months. Restudy Subgroup For subjects who are clinically indicated for staged procedure, they will be recruited into restudy subgroup. Restudy angiogram of target lesion will be performed at 28 (±7) days. Intravascular OCT will be performed. The primary endpoint is target lesion failure (TLF) defined as composite of cardiovascular death, target-vessel related myocardial infarction (Q-wave and non-Q-wave), or ischemia-driven target lesion revascularization within 12 months (device-oriented outcome per ARC definitions) The co-primary endpoint in subjects who require stage procedure is stent strut coverage (degree of endothelialisation) as assessed by optic coherence tomography (OCT) at one month Secondary endpoints include 1. All-cause mortality 2. Cardiovascular death (cardiovascular and undetermined) 3. The composite of cardiovascular death, Target Lesion (TL)-related myocardial infarction and TL-related definite or probable stent thrombosis at one year. 4. Stroke disabling and non-disabling ARC definition 5. Myocardial infarction 6. ARC Stent thrombosis 7. Clinically driven TLR at any follow-up time point 8. Clinically driven target vessel revascularization 9. Any revascularization within 12 months following the index procedure, unless they are planned within the 1st month 10. Bleeding per BARC criteria For subjects in restudy subgroup 11. Restudy angiographic result (QCA) 12. OCT parameters including neointimal volume, neointimal area etc
As a result, will be developed: a list of criteria for functional impairment in patients after myocardial revascularization combined with low back pain; a list of criteria for disabilities in patients after myocardial revascularization combined with low back pain; method of medical rehabilitation of patients after myocardial revascularization combined with low back pain; and criteria for evaluating its effectiveness.
