Active clinical trials for "Ischemia"

The present study evaluates skin microvascular reactivity and coronary physiology in the same coronary artery disease (CAD) patients. This study is expected to find associations between systemic microvascular reactivity, measured non-invasively at the skin surface, and coronary reserve evaluated by the invasive angiographic method.

The purpose of this study is to determine whether DEB is not inferior to common bare metal stent using under in long-term vessel patency and inhibiting restenosis in Vertebral Artery Ostium Stenosis

Among patients with stable ischemic heart disease who are referred for coronary angiography, a substantial proportion have non-obstructive coronary artery disease (CAD). Ischemia based on symptoms or stress testing may be due to coronary microvascular dysfunction in up to 40% of these patients. However, the mechanisms and optimal treatment of coronary microvascular dysfunction are unknown. Aberrant platelet activity and inflammation have been hypothesized as mechanisms of microvascular dysfunction. Investigators plan to evaluate association between platelet activity, inflammation, and coronary microvascular dysfunction in stable women referred for coronary angiography, and to identify non-invasive correlates of coronary microvascular dysfunction in these patients.

The aim of this study is to investigate whether near-infrared guided percutaneous coronary intervention in patients with acute myocardial infarction provides improved stent strut coverage at six months compared to conventionally angiography guided percutaneous coronary intervention.

LIFE-BTK PK is a prospective, single-arm, open-label, non-blinded, non-randomized sub-study of LIFE-BTK Randomized Controlled Trial (NCT04227899), that will enroll approximately 7 subjects in the United States (US) and outside the US with a maximum of 5 sites in the US. Of the 7 subjects planned to be enrolled, 4 subjects will be treated with Esprit BTK in below the knee artery(ies) in whom drug-coated balloons (DCB) were not used; 3 subjects will be treated with Esprit BTK in below the knee artery(ies) in whom DCB were used for treatment of inflow disease.

Anomalous Aortic Origin of the Coronary Arteries (AAOCA) is a rare congenital disease that may cause sudden death in young subjects. Frequently the first and only presentation is with an acute event (such as myocardial infarction or sudden cardiac deaths) during physical effort. Not only symptoms are often absent, but also provocative tests fail to induce ischemia or related signs, showing in most patients negative results. For these limitations, the decision to undergo corrective surgery is based on the morphologic characteristics without the support of a functional evaluation. The study focused on developing a personalized ischemic risk assessment with the aid of fluid dynamic simulations. The simulation system integrate clinical data from different diagnostic sources and integrate them with coronary blood flow evaluation at rest and during simulated physical effort.

The purpose is to compare median two-year clinical outcome after OCT guided vs. standard guided revascularization of patients requiring complex bifurcation stent implantation

It is known that atrial fibrillation after stroke significantly increases the risk of stroke or systemic embolism. Accordingly, efforts have been made to detect hidden atrial fibrillation and apply treatment using anticoagulants instead of antiplatelet agents. The conventional method used to screen for atrial fibrillation in stroke patients who did not have atrial fibrillation at first admission is 24-hour Holter monitoring. This study will compare the detection rate of atrial fibrillation with discontinuous ECG monitoring three times a day and 72 hours of single-lead ECG patch monitoring compared with the conventional Holter test.

The aim of the biomedical research is to determine the informativeness and prognostic factors of surface electromyography by assessing the probability of recovery of balance and gait parameters in the second stage of rehabilitation of persons with cerebral infarction.

Neonatal anoxia-ischemia causes significant neurodevelopmental disorders. In this study the investigators want to better understand the interactions between the nervous and the hemodynamic cerebral systems during the adaptation of the neonate to ectopic life just after birth. Birth is an at risk situation of neonatal anoxic ischemia and the lack of objective criteria for cerebral tissue oxygenation has consequences on neuronal activity. Ph cord analysis is inadequate and only indirectly reflects the state of cerebral oxygenation. Both neuronal and vascular systems are part of the same functional entity and the analysis of their interactions is likely to reveal some early malfunctions of these networks. In this study, the investigators want to develop a multi-scale, multimodal approach that allows simultaneous interrogation of both neuronal and vascular compartments during the 15 minutes after delivery. The investigators will record, with the aid of a single sensor placed on the scalp of the child, the electroencephalogram and the cerebral tissue oxygenation. The investigators will measure interactions by means of correlation analysis between both signals.
