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.

Detailed description

This is a single-center randomized controlled study conducted to explore the efficacy and safety of antithrombotic therapy with regulation of blood pressure in non-cardioembolic PIS. We plan to recruit 70 patients with non-cardioembolic PIS. All subjects are of Han ethnicity, aged 18 years or older. Gender and age will be statistical data after enrollment. Patients will participate in the study after informed consent. Then patients who meet the inclusion and exclusion criteria will be randomly assigned in a 1:1 ratio to the control group (antithrombotic therapy) or the intervention group (antithrombotic + blood pressure control therapy). In addition to antithrombotic therapy, the intervention group will use medications such as dopamine, metaraminol, or midodrine to control systolic blood pressure within the range of 160-180 mmHg and maintain it for one week. Patients will be followed up at 2 weeks for mRS (Modified Rankin Scale) and NIHSS (National Institutes of Health Stroke Scale) scores，and at one month for mRS scores, and at three months for mRS and BI (Barthel Index) scores.

Interventions

Type	Name	Description
OTHER	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.
