Active clinical trials for "Ischemia"

Butylphthalide, as a well-known neuroprotective medication, is a family of compounds initially isolated from the seeds of Apium graveolens Linn, of which active ingredient is dl-3-N-butylphthalide (dl-NBP). With the significant effects of reducing the cerebral ischemic damage and eventually improving patients' clinical outcomes, by the potential mechanisms of promoting microcirculation, as well as releasing oxidative stress, mitochondrial dysfunction and poststroke inflammation, dl-NBP has been widely applied in acute ischemic stroke as an anti-ischemic drug in China since 2002. While with the evolution of using iv. recombinant tissue plasminogen activator（rtPA ）and mechanical thrombectomy in acute ischemic stroke（AIS）patients, it is still undefined whether combination therapy with dl-NBP could enhance the curative effect. The primary purpose of this trial is to evaluate the recovery of neurological deficits in AIS patients who receive iv-rtPA and/or mechanical thrombectomy with the a 3-month regimen of Butylphthalide and Sodium Chloride Injection 100ml twice/day in the initial 14 days and Butylphthalide Soft Capsules 0.2g triple/day for the rest 15th to 90th day therapy versus a 3-month regimen of Butylphthalide Placebo Injection 100ml twice/day in the initial 14 days and followed by Butylphthalide Placebo Soft Capsules 0.2g triple/day for the rest 15th to 90th day therapy.

Remote ischemic postconditioning (RIPC) is suggested to protect the cerebral cell against ischemia in various settings. However, the effect of RIPC in patients with acute ischemic stroke who undergo thrombolysis has yet to be examined. In this single-center, randomized controlled trial, we examined the effect of RIPC on the resolution of nerve function deficient in response to thrombolysis. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after thrombolysis. The primary endpoint was the recovery of nerve function deficient assessed by National Institutes of Health Stroke Scale(NIHSS), Activities of Daily Living(ADL), Modified Rankin Scale(mRS), CT cerebral perfusion imaging (CTP) and CT angiography(CTA). Secondary endpoints included the following: angiogenesis assessed by the level of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF).

BOSS-Trial I is a phase 2 clinical trial with the following objectives; to prove the feasibility of a Bluetooth-equipped sphygmomanometer system in real-world clinical practice and wireless connection to the main server; to prove the feasibility of the BP management strategy, including the pre-specified BP range, BP management algorithm, and behavioral; and to gather information for the phase 3 trial including BP variability indices and their potentials as a treatment guidance.

The aim of our study was to evaluate the technical and clinical effectiveness of PTA in the management of ischemic foot ulcers. All consecutive patients presenting with a foot ulcer at the outpatient Vascular surgery clinic of our hospital were evaluated. If non-invasive parameters suggested peripheral arterial disease (PAD) anatomic imaging (CTA and/or DSA) was performed and a PTA was carried out when feasible during the same session. All patients were followed until healing, amputation, death, or for at least two years. Short-term and long-term clinical success of PTA was evaluated based on ulcer size and appearance. Patients with worsening ulcers after PTA underwent bypass grafting or amputation.

Remote ischemic preconditioning(RIPC) is emerging as an promising therapeutic paradigm to combat the detrimental impact of ischemic and reperfusion injury. In liver transplantation, ischemic and reperfusion injury severely impacts the post-surgery liver function and patient outcome. This prospective, double blind, randomized clinical trial is aimed to test the protective effect of RIPC against hepatic ischemic and reperfusion injury in pediatric liver transplantation.

This study was a multicenter, randomized, controlled pilot trial of moderate systemic hypothermia (33°C) vs normothermia (37°C) for 48 hours in infants with neonatal encephalopathy instituted within 6 hours of birth or hypoxic-ischemic event.

The aim of this study is to evaluate the safety and effectivity of Ginkgo diterpene lactone meglumine injection tn the treatment of acute ischemic stroke

Ticagrelor is a reversible and direct-acting oral antagonist of the P2Y12 (Purinergic receptor P2Y, G-protein coupled, 12) receptor for adenosine diphosphate, which provides faster, greater, and more consistent P2Y12 inhibition than Clopidogrel in patients with acute coronary syndrome, irrespective of the genetic variants affecting Clopidogrel metabolism. It is still undefined whether combination therapy of Ticagrelor and Aspirin is more effective than Clopidogrel and aspirin for minor stroke and transient ischemic attack (TIA). The primary purpose of the PRINCE trial is to evaluate the anti-platelet effects of a 3-month regimen of ticagrelor initiated with 180 mg loading dose followed by 90 mg twice/day combined with aspirin 100 mg/day during first 21 days versus a 3-month regimen of clopidogrel initiated with 300 mg loading dose of followed by 75 mg/day combined with aspirin 100 mg/day during first 21 days when initiated within 24 hours of symptom onset in high-risk transient ischemic attack or minor stroke.

The main objective of this study is to compare the incidence of detected atrial fibrillation (AF) in cryptogenic stroke patients by a single lead ECG device with the incidence of detected AF by a 7-Day Holter ECG.

This is a prospective, non-randomized, open label, multi-center study including 60 patients with symptomatic ischemic heart disease with 70%-100% coronary artery stenoses and occlusions enrolled and treated in this investigational device study.
