Antithrombotic Therapy With Regulation of Blood Pressure in Non-Cardioembolic Progressive Stroke
Sponsor: Ruijin Hospital
Summary
Stroke has become the leading cause of death in China, with acute ischemic stroke still progressing within one week of onset, known as progressive ischemic stroke (PIS), which has a high rate of disability and mortality, accounting for 23-43% of the incidence of stroke. Non-cardioembolic PIS is one of the common types, and the current treatment mainly focuses on antithrombotic therapy, but the therapeutic effect is not satisfactory. More and more evidence suggests that hypotension is an unfavorable factor for PIS, so this study intends to explore the efficacy and safety of antithrombotic therapy with regulation of blood pressure in non-cardioembolic PIS.

Intervention group
After stroke progression, all patients receive dual antiplatelet therapy (aspirin 100mg/day combined with clopidogrel 75mg/day) for the first 21 days, except in cases of cerebral hemorrhage. After this period, they continue to take aspirin 100mg/day orally for the long term. In terms of blood pressure control, medications such as dopamine, metaraminol, or midodrine are used to achieve a systolic blood pressure target range of 160-180 mmHg within 1 h of random assignment and to maintain this target for 7 days (or death, should this event occur earlier). BP measurements are routinely captured using automated devices fitted to the unaffected arm, following the protocol recommended by the standard guideline. The readings are taken at 15-minute intervals for the initial hour, hourly from the first to the sixth hour, every six hours from 6 to 24 hours, and then twice daily for 7 days (or death, if earlier). Subsequently, these data are uploaded into the research database.
