Active clinical trials for "Ischemia"

The purpose of this study is to evaluate the technical feasibility, safety, and 1-year clinical efficacy of the endovascular treatment of patients with atherosclerotic common femoral artery (CFA) obstructions with associated superficial femoral artery lesions. Participants will undergo angioplasty with or without stenting of common femoral and superficial femoral arteries.

When an individual experiences a sudden onset of neurological symptoms, such as one-sided weakness, visual abnormalities, and/or slurred speech, there is concern that they are having a transient ischemic attack/stroke. A stroke is a medical emergency that requires immediate treatment and further evaluation to prevent a future stroke. Unfortunately, when a patient presents to the emergency department or a clinic with transient or mildly observable neurological symptoms, it is difficult to diagnose a stroke and many times, imaging may not reveal a stroke. This poses the risk of discharging patients without appropriate stroke care. This study aims to evaluate the feasibility of administering portable electroencephalogram (EEG) devices to diagnose transient ischemic attack/stroke. An EEG is a device that measures electrical activity in the brain. This study involves comparing EEG data of individuals who present with transient neurological symptoms or have known stroke with EEG data of generally healthy individuals. From this study, the investigators anticipate that it will be feasible to administer portable EEG and that portable EEG can be used to accurately diagnose stroke.

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).

The ischemia/reperfusion (I/R) injury of the myocardium initiates a variety and complex sets of inflammatory reactions that may both exaggerate local injury as well as provoke injury of distant organ function . I/R injuries are the main causes of heart failure, morbidity, and mortality after cardiac surgery such as coronary artery bypass graft (CABG surgery) . The reactive oxygen species are believed to be excessively elevated during coronary artery bypass surgery (CABG) due to compromised free radical scavenging mechanism in the myocardium that can make myocardium highly susceptible to oxidative stress and inflammation and result in reperfusion injury . Melatonin and its metabolites protect against inflammation by regulating several inflammatory cytokines. Additionally, melatonin is a free radical scavenger and an antioxidant agent. the current study is designed to investigate the protective effects of melatonin against myocardial I/R injury in patients undergoing coronary artery bypass grafting (CABG) surgery.

The objective of this prospective, single-blinded, randomized controlled trial is to evaluate the safety and efficacy of the MAGNITUDE BRS System for the planned treatment of narrowed infrapopliteal lesions. Approximately 300 subjects will be randomized in a 1:1 ratio. The clinical investigation will be conducted at approximately 50 clinical sites internationally.

The REAl-life study on short-term Dual Antiplatelet treatment in Patients with ischemic stroke or Transient ischemic attack (READAPT) is an observational, multicenter, prospective study involving Italian centers. The study aims at evaluating effectiveness and safety of short-term (21-90 days) dual antiplatelet treatment (DAPT) in secondary prevention of mild-to-moderate ischemic stroke or high-risk TIA.

Hypothermia with intrajugular cooling is a neuroprotective strategy that has been proven to minimize brain damage and maximize functional preservation in animal models of stroke. The purpose of this proof-of-concept study is to determine the safety and tolerability of intrajugular cooling in patients with acute ischemic stroke who are treated with mechanical thrombectomy.

Acute ischemic stroke registry--Xuanwu Hospital(XSR) is an academic, independent, prospective, single center, observational registry study. Consecutive acute ischemic stroke patients assessed in stroke "green channel" of Xuanwu Hospital(China) will be enrolled in our study. Patients receive regular treatment and data will be collected as part of clinical routine. Baseline clinical and procedural information as well clinical follow-up information during in-hospital stay, and up to 90 days of stroke onset are collected. Data collected include demographics, National Institute of Health Stroke Scale (NIHSS) on admission, pre-treatment ASPECTS, information on timing and success of thrombolysis or thrombectomy, procedural complications, intracranial hemorrhage, and functional outcome.The study aim to investigate the real situation of assessment, diagnosis and treatment of acute ischemic stroke patients in "green channel",and verify the effect of the improvement of "green channel" process in the diagnosis and treatment of patients with acute ischemic stroke.

The aim of the Naples PCI registry is to collect prospective data on baseline clinical, laboratory, and angiographic characteristics of patients undergoing PCI for acute or chronic coronary artery disease. All patients receive clinical follow-up at hospital discharge and at 1-year follow-up with the objective to assess clinical outcomes, including death, cardiovascular death, myocardial infarction, stroke, stent thrombosis, target-lesion and target-vessel revascularization, contrast-induced acute kidney injury, and bleeding events.

The primary goal of the study is to obtain effect size data on the use of Shockwave Intravascular Lithotripsy (IVL) technology in calcified common femoral lesions in patients with peripheral artery disease for a series of endpoints, including target lesion revascularization and health status, to enable future planning of comparative effectiveness research.
