This study will evaluate the efficacy and safety of tenecteplase compared with placebo in participants with acute ischemic stroke (AIS). All participants will receive standard-of-care therapy according to AmericanHeart Association/American Stroke Association clinical guidelines (2018). To determine eligibility for randomization, all participants will undergo multimodal CT or MRI at baseline. Only participants with a vessel occlusion (ICA or MCA M1/M2) and penumbral tissue will be randomized. The primary analysis is to compare the efficacy of tenecteplase versus placebo in all participants at Day 90.
Of the patients diagnosed with ST-segment elevation myocardial infarction (STEMI) who underwent reperfusion therapy and have thrombolysis in myocardial infarction (TIMI) 3 flow, about 40% have flow alterations in the coronary microcirculation, which leads to worse remodeling of the left ventricle with a consequent increase in the mortality of this population. Clopidogrel is the only known antiplatelet medication that brings benefits to the coronary microcirculation. Ticagrelor is significantly superior to clopidogrel in terms of decreasing mortality. The main objective of this study is to compare the effect of ticagrelor versus clopidogrel on the coronary microcirculation by the Myocardial Perfusion Score Index (MPSI) obtained using Microbubble Contrasted Echocardiography (MCE) in patients who have STEMI and treated with thrombolysis.
Stroke is a leading cause of death and disability, and 15 million people suffer a stroke each year; one-third die and one-third are left permanently disabled. Because the risk of stroke increases with age, it has been considered a disease of the elderly, but stroke also occurs in middle-aged people. Thrombolysis with tissue plasminogen activator (tPA) is the preferred choice of reperfusion therapy of ischemic stroke if performed within 4.5 hours from symptom onset. Time to thrombolysis is associated with improved outcome: the sooner the treatment, the less risk of serious - and possibly permanent - damage to the brain. Unfortunately, only a small fraction of stroke patients make it to thrombolysis within the 4.5-hour; one explanation may be system delays including prolonged transportation. In May 2010, the first physician-staffed Helicopter Emergency Medical Service (HEMS) was implemented in the Eastern part of Denmark. An observational study evaluating the short-term effects of HEMS implementation compared patients transported by conventional ground ambulance (Ground Emergency Medical Service (GEMS)) to patients transported by HEMS. Patients transported by helicopter had increased time to specialized care. However, both 30-day and 1-year mortality was slightly lower in patients transported by HEMS, although not significant, as was the degree of disability at three months measured by the modified Rankin Scale (mRS).
