Filter by:To observe the safety and efficacy of intensive drug therapy for ischemic stroke patients.Patients with acute stroke caused by intracranial arterial stenosis (stenosis rate ≥70%) were enrolled and accept dual antiplatelet therapy (DAPT) (aspirin 100 mg/d and clopidogrel 75 mg/d for 90 days, followed by aspirin 100 mg/d for long term) under the guidance of platelet function analysis (Verifynow) combined with the intensive statin therapy (40 mg/d for 14 days, followed by 20 mg/d for long term).
This study is a multicenter observational study designed to evaluate the the effectiveness and safety of drug-coated balloon (DCB) angioplasty for below the knee arterial lesions in patients critical with Limb Threatening Ischemia (CLTI).
Consequences of stroke are manyfold but all of them are important factors on the long-term outcomes of rehabilitation, becoming an important health problem with requires health strategies with advanced age. High intensity interval training (HIIT) is an efficient training protocol used in cardiac rehabilitation programs, but owing to the inter-individual variability in physiological responses to training associated to cardiovascular diseases, the exercise dose received by each patient should be closely controlled and individualized to ensure the safety and efficiency of the exercise program. The heart rate variability (HRV) is actually being used for this purpose, as it is closely linked to de parasympathetic nervous system activation. In this way, higher scores in HRV are associated with a good cardiovascular adaptation. The objective of this protocol is to determine the effect of HIIT compared with HRV-guided training on cardiorespiratory fitness, heart rate variability, functional parameters, body composition, quality of life, inflammatory markers, cognitive function, and feasibility, safety and adherence in patients after stroke undertaking an 8-week cardiac rehabilitation program. This will be a cluster-randomized controlled protocol in which patients after stroke will be assigned to an HRV-based training group (HRV-G) or a HIIT-based training group (HIIT-G). HIIT-G will train according to a predefined training program. HRV-G training will depend on the patients' daily HRV. The peak oxygen uptake (VO2peak), endothelial and work parameters, the heart rate variability, the functional parameters, the relative weight and body fat distribution, the quality of life, the inflammatory markers, the cognitive function, and the exercise adherence, feasibility and safety will be considered as the outcomes. It is expected that this HRV-guided training protocol will improve functional performance in the patients after stroke, being more safe, feasible and generating more adherence than HIIT, providing a better strategy to optimize the cardiac rehabilitation interventions.
The core hypothesis to be tested is that the radiosurgery of stellate ganglion (left one or both if left-sided without full relief of symptoms) is an effective therapy of refractory angina pectoris in patients with no other therapeutic options - proof of concept study.
The purpose of this study is to explore the effect of remote ischemic conditioning on the dynamic cerebral autoregulation in patients with intracranial and extracranial arteriosclerosis and the changes of dynamic cerebral autoregulation within 24 hours after remote ischemic conditioning.
The primary aim of the study is the evaluation of the efficacy of remote ischemic preconditioning (RIPC) in terms of increase of the clearance of lactates 4 hours after the end of the hepatic resection. The secondary aims of the study are represented by the evaluation of the patients' postoperative recovery and the restoration of a normal lactate metabolism.
A Randomized, Placebo-Controlled, Double-Blind, Multicenter Study of the Safety and Neuroprotective Capacity of Scp776 in Subjects Undergoing Endovascular Thrombectomy for Acute Ischemic Stroke
The study is a two-center prospective cohort clinical trial. The primary purpose of this trial is to identify the pattern of DKK2 serum levels in ischemic stroke patients after revascularization therapy and determine the correlation between serum DKK2 levels and prognosis.
To conduct a quality assurance project to establish the differences in health care processes and cost effectiveness of having the thin-strut Orsiro stent versus the thicker strut Promus stent on the shelf (i.e. as the most accessible stent).
As a major breakthrough of acute stroke treatment over the past decade, endovascular thrombectomy (EVT) drastically improved neurological recovery and survival in patients with large vessel occlusion (LVO) ischemic strokes in major clinical trials. Nevertheless, much remained uncertain about the implementation of scientific evidence of EVT into real-world benefits. For instance, healthcare policies that influence critical time-matrices, endovascular thrombectomy techniques that may enhance success rate or prevent complications, or advanced imaging techniques that allow precise prognosis or expansion of treatment populations, should be evaluated. On the other hand, capturing LVO patients who were not able to undergo EVT may reveal the gap between clinical trials and real-world practice in the Asia-Pacific. In this multicenter prospective collaboration across the Asian-Pacific, the investigators aim to evaluate the determinants of effective EVT in the real-world setting.
