Active clinical trials for "Ischemia"

This is a double-blind parallel arm randomized trial aimed to assess efficacy and safety of intravenous Tenecteplase compared to intravenous Alteplase in eligible patients who present with symptoms of acute ischemic stroke within 3 to 4.5 hours from onset.

In the present study the investigators will evaluate MMPs. serum levels variations in patients affected by critical limb ischemia, before and after lower limb surgical revascularization through venous or prosthetic bypass.

The purpose of this study is to evaluate the feasibility of rapid evaluation and administration of ophthalmic Timolol maleate in the treatment of non-arteritic anterior ischemic optic neuropathy. Secondary goals are to evaluate if such treatment reduces the progression or improves recovery of patients who are randomly assigned to treatment versus standard of care.

A double blinded and placebo-controlled, dose escalation, single-center safety and preliminary efficacy study of cardiospheres delivered via NOGA MYOSTAR injection catheter in subjects with chronic ischemic cardiomyopathy. The objective is to achieve and document myocardial regeneration in patients with chronic scar.

Primary objective: To demonstrate superiority of enoxaparin 40 mg sc qd in the prevention of VTE compared to UFH (unfractionated heparin) 5000 U sc q12 hours given for 10 ± 4 days following acute ischemic stroke. Secondary objectives: To compare the incidence of VTE between the 2 treatment groups at 30, 60, and 90 days from the time of randomization To compare neurologic outcomes between the 2 treatment groups, including incidence of stroke recurrence, rate of stroke progression, and patient functional status, during the 10 ± 4 days of treatment, and after 30, 60, and 90 days from the time of randomization To evaluate the safety of using enoxaparin compared to UFH for VTE prevention in patients following acute ischemic stroke

To determine if the combined incidence of nonfatal myocardial infarction and coronary heart disease death differs between diuretic-based and each of three alternative antihypertensive pharmacological treatments. Also, to determine, in a subset of this population, if lowering serum cholesterol with a HMG CoA reductase inhibitor in older adults reduces all-cause mortality compared to a control group receiving usual care. Conducted in conjunction with the Department of Veterans' Affairs.

To determine whether modification of risk factors altered the rate of progression of coronary artery disease in arteries with mild atherosclerosis and no mechanical intervention in patients who had coronary bypass surgery or percutaneous transluminal coronary angioplasty (PTCA).

In this prospective single-center observational study, arterial perfusion in patients with lower limb peripheral arterial disease will be assessed with standard diagnostic tools (toe pressure, trans-cutaneous oxygen pressure, ankle-brachial index and fluorescence angiography) before and after standard revascularization procedures (open surgery and/or angioplasty).

The investigators will be using nocturnal normobaric hyperoxia therapy in patients with diagnoses of conditions related to retinal ischemia.

The aim of this study is to compare total procedure time and success rate between FL-guided and US-assisted LSGBs in Lower Limb Ischemic patients.
