Active clinical trials for "Ischemia"

The objective of this study is to assess the safety and efficacy of the DREAMS 3G in the treatment of subjects with up to two de novo lesions in native coronary arteries compared to a contemporary drug eluting stent (DES).

This is a single center, randomized, double-blind, placebo-controlled, dose-Escalation clinical study to investigate the safety and efficacy of EPCs transplantation in Acute ischemic stroke.

False positive results are commonly observed in women after exercise treadmill test (ETT). The effects of menstrual periodic changes on the results of exercise treadmill test in premenopausal women have not been clearly defined. Primary purpose of the study is to investigate the biological causes of false positive test results in the treadmill exercise test in premenopausal women. Estrogen is known to have direct vasodilatory effects on coronary arteries. Early and late follicular phases of the menstrual cycle are characterized by low and high estrogen levels, respectively. The Early Follicular Phase starts on the first day of the menstrual cycle and ends when oestradiol begins to increase. It is characterised by increasing LH and FSH and constant low levels of oestradiol. The late follicular phase starts with the increase in oestradiol and ends at its preovulatory peak. The hypothesis of the study is that ETT results will change at the early and late follicular phases in premenstrual women. Premenopausal women between the ages of 18-40, who apply to the cardiology outpatient clinics of Göztepe City Hospital with typical/atypical chest pain, and an indication for ETT will be included in the study. ETT will be performed in the early and late follicular phases of the menstrual cycle, separately.

The purpose of this study is to determine the effect of remote ischemic conditioning on cerebral autoregulation in patients undergoing cerebrovascular stent implantation.

This early phase trial will address the following key objectives: Completion of initial safety and tolerability testing of our viable prototype for remote ischemic conditioning (RIC) with patients with (a) CSVD and (b) acute ischemic stroke. Usability testing of the prototype with patients and healthcare professionals, with further optimization. Approximately 24 patients with CSVD will be recruited to use the RIC device daily for 60 days and provide feedback. They will be randomized in a 1:1 ratio to either true RIC therapy or sham control for the first 30 days, after which the sham group will cross over to receive true RIC for the remaining 30 days. Feasibility testing will be done in the mobile stroke unit on up to 10 patients with acute ischemic stroke. An additional 10 stroke physicians and paramedics will conduct device usability testing and provide feedback.

Trans-arterial chemoembolization (TACE) is the most commonly used therapy for patients with unresectable hepatocellular carcinoma (HCC). TACE is a minimally invasive procedure that involves placing a catheter into the artery in the liver that feeds the tumor, administering chemotherapeutics and then blocking the artery with embolics in order to kill tumor cells by depriving them of essential oxygen and nutrients. While TACE has a proven survival benefit, local recurrence is common, and long-term survival rates are poor. Prior studies demonstrate that HCC cells survive the oxygen and nutrient deprivation through autophagy, a process of cellular self-eating, to provide nutrients required for survival. The proposed project will leverage this dependency to develop a novel approach to TACE that integrates autophagy inhibition to improve therapeutic response by increasing tumor cell killing and enhancing anti-tumor immunity.

The goal of this observational, practice-based feasibility study is to observe the efficacy and safety of intramuscular administration of Stempeucel® in Malaysian patients with critical limb ischemia (CLI) due to Buerger's disease. The main questions it aims to answer are: Can intramuscular administration of Stempeucel® reduce symptoms of CLI due to Buerger's disease while improving the healing rate and functional outcomes? Does intramuscular administration of Stempeucel® causes any serious adverse events in CLI due to Buerger's disease patients? Study patients will be assessed by the PI before administering the Stempeucel® for any other organ with inflammation. The study patients will also be followed up to the duration of 1 year after study treatment administration for safety and efficacy assessment.

Remote ischemic conditioning (RIC) is a non-invasive therapeutic approach for protecting organs or tissue against the detrimental effects of acute ischemia-reperfusion injury. Many protective factors produced by the stimulus of RIC could protect remote target organs and tissues through inhibiting oxidation and inflammation. The phenomenon of this protect effect was first found in myocardium ischemia-reperfusion injury and then RIC was used in children cardiac surgery to provide myocardial protection during operation. Then RIC was gradually applied to brain protection and a series of clinical researches have confirmed that it could improve the cerebral perfusion status, increase cerebral tolerance to ischemic injury, reduce perihematomal edema and promote clearance. Recently, a randomized controlled study reported that daily RIC could improve cerebral perfusion and slow arterial progression of adult MMD. Meanwhile, a single-arm open-label study also indicated that RIC was a promising noninvasive method for ischemic MMD control by relieving symptoms and reducing stroke recurrence. In addition, the effects of RIC on reducing neurological complications in MMD patients treated with revascularization surgery has also been reported. However, the mechanism of RIC in reducing peri-operative complications for MMD patients is still unknown. Thus, we conducted a randomized controlled study to explore the safety and efficacy of RIC in adult MMD patients undergoing revascularization therapy

The study aims to assess contemporary practice in OCT use during routine interven-tional practice and to assess the impact of the MLD-MAX algorithm on real-world PCI in a large unselected European all-comer-study cohort.

This study intends to further reveal the effect of RIC in stroke-related insomnia and explore its potential mechanisms.
