Active clinical trials for "Atherosclerosis"

In acute ischemic stroke caused by intracranial large vessel occlusion, rescue intracranial stenting has been recently a treatment option to achieve recanalization in patients with the failure of mechanical thrombectomy. Nevertheless, there are few studies supporting this beneficial treatment in two cerebral circulations. We aimed to analyse whether the use of rescue intracranial stenting would improve prognosis of patients at 3 months.

It is a randomized study that intend to enroll 80 bellow-the-knee angioplasty procedures in which 40 procedures to treat one artery (standart) or more than one artery in the same procedure. The aim of this study is to know if this strategy increase healing velocity and limb salvage.

The aim of the study is to compare clinical outcomes between intravascular imaging-guided versus angiography-guided percutaneous coronary intervention (PCI) in complex lesions.

Study the mechanisms of atherosclerosis based on a comparative study of physical and chemical properties of lipid tissues at various localization with subsequent development of concept of treatment and prevention.

The purpose of this study is to determine whether reducing inflammation in blood vessels with an aspirin-like drug called salsalate will improve blood vessel function.

Hardening of the arteries (atherosclerosis) and heart disease are much more common in men than in women. However, as women grow older, especially after menopause the incidence of atherosclerosis and heart disease increases. These findings suggest that estrogen may be protective and help in preventing heart disease. Studies of large groups of post-menopausal women suggest that hormone replacement therapy (therapy that includes estrogen) reduces the risk of heart disease. Estrogen causes favorable changes in particles that carry cholesterol in the blood stream and improves function of blood vessels. Estrogen may also stimulate the immune system's ability to fight off infections that may lead to or contribute to atherosclerosis. Researchers believe two specific infectious agents (Chlamydia pneumoniae and human cytomegalovirus) may cause damage to the lining of blood vessels resulting in inflammation and the development of atherosclerosis. The purpose of this study is to determine if estrogen treatment can change how the immune system responds to chronic infections, by Chlamydia pneumoniae and human cytomegalovirus, in postmenopausal women.

The objective of this post-approval study is to confirm that the clinical performance of the Orsiro stent in a real-world setting is similar to the clinical performance observed for Orsiro in the BIOFLOW-V Investigational Device Exemption pivotal trial, as a condition of the US Food and Drug Administration (FDA) approval (P170030).

The purpose of this study is to evaluate the utility of 18Fluorine Fluorodeoxyglucose Positron Emission Tomography (18FDG-PET) as a tool to quantify atherosclerotic plaque.

The purpose of the DEBIUT study is to assess procedural, clinical and angiographic outcomes of: Provisional T-stenting use for dilation the Paclitaxel-eluting PCI-balloon (DiorTM) in comparison to dilation with a standard balloon prior to the implant of the Liberty Bare Metal Stent in bifurcation lesions (with side branch involvement). Comparison of the results above with the results of using a standard balloon prior to provisional T-stenting with the Paclitaxel-eluting stent TaxusTM LibertéTM.

The primary objective of this study is to prove the superior performance of the Ranger™ paclitaxel-coated PTA balloon catheter for angioplasty for femoropopliteal artery lesions when compared to non-coated balloons at six months post-procedure when comparing Late Lumen Loss (LLL). Study statistical hypothesis: The %-mean loss of luminal diameter as assessed by angiography at six months follow-up after treatment of the femoropopliteal artery with Ranger DCB study devices is lower than the %-mean loss of luminal diameter after treatment with uncoated PTA balloon control devices.
