Active clinical trials for "Ischemia"

A Phase Ⅲ, Multicenter, Prospective, Randomized, Open Label, Blinded-endpoint (PROBE) Controlled Trial of Recombinant Human TNK Tissue-type Plasminogen Activator (rhTNK-tPA) for Injection Versus Alteplase for Acute Ischemic Stroke Within 4.5 Hours

The purpose of this study is to determine the impact of serial remote ischemic conditioning on dynamic cerebral autoregulation and related hematology indexes in healthy adults.

The purpose of this study is to determine the impact of remote ischemic conditioning on dynamic cerebral autoregulation in patients with acute ischemic stroke receiving intravenous thrombolysis.

The aim of the study is to collect and analyze specimen from ischemic stroke patients undergoing thrombectomy procedures and from patients undergoing minimally invasive surgery for intracranial hematoma evacuation.

Retinal ischemia characterization in diabetes - RICHARD

To investigate the clinical value of quantitative analysis of peri-operative foot supply through CT perfusion in patients with critical limb ischemia

The investigators evaluated whether the characteristics of ischemic stroke patients, door-to-needle time, and stroke risk factors were predictive variables for unfavourable outcomes.

Secondary brain ischaemia (SBI) usually develops after aneurysmal subarachnoid haemorrhage (SAH) and severe traumatic brain injury (TBI). The current management strategies are based on intracranial pressure-targeted therapy (ICP-targeted) with cerebral microdialysis monitoring (modified Lund concept) or cerebral perfusion pressure-targeted therapy (CPP-targeted). We present a randomised controlled study to compare the two management strategies. The hypotheses of the study were: SBI developed after aneurysmal SAH and severe TBI share the same crucial characteristics and any treatment applied will essentially treat the same underlying pathophysiology. ICP-targeted therapy with cerebral microdialysis monitoring according to the modified Lund concept is superior to CPP-targeted therapy in managing comatose patients with SBI after aneurysmal SAH and severe TBI. Sixty comatose operated patients with SBI following aneurysmal SAH and severe TBI were randomized into ICP-targeted therapy with cerebral microdialysis monitoring and CPP-targeted therapy groups. Mortality rates in both groups were calculated and biochemical signs of cerebral ischaemia were analysed using cerebral microdialysis. Outcome for cerebral microdialysis was measured as poor outcome (Glasgow Outcome Scale score 1, 2 and 3) or good outcome (Glasgow Outcome Scale score 4 and 5).

Our primary goal is to study temporal trends in the incidence rate, causes, treatment, and outcome of stroke among a large biracial metropolitan population of 1,349,351, of whom 215,611 (15%) are black (2000 Census). Such data are critical for the planning, intervention, and evaluation of public health efforts to decrease the mortality and morbidity due to stroke in the United States. We have completed this goal for 1993-94, 1999, 2005, 2010 and 2015. We are in the process of collecting this data for 2020. In the 2020 study period we will also be ascertaining 3 year recurrence rates for all incident stroke events.

The primary objective of this study is to test that endocardial stem cells implantation in patients who have CAD, low ejection fraction and signs of HF without possibility of CABG and PCI or despite on previous revascularization improves long-term survival compared to MED alone
