Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Usual BP management group
Procedure: Usual BP management group
To receive blood pressure management according to standard local guidelines. In China, for patients scheduled for intravenous thrombolysis who present with elevated blood pressure, it is advised to maintain blood pressure below 180/100 mmHg for 24 hours, after which standard guideline-based blood pressure management should be resumed.
Experimental: Adjusted BP management group
Procedure: Adjusted BP management group
For patients intended to receive intravenous thrombolysis, when the blood pressure ranges from 180/100 mmHg to 200/110 mmHg, simultaneous initiation of both intravenous thrombolysis and antihypertensive treatment can be considered. If the blood pressure exceeds 200/110 mmHg, antihypertensive treatment should be initiated first. Intravenous thrombolysis can be commenced after the blood pressure is reduced to below 200/110 mmHg. Before thrombolysis and within 24 hours after the initiation of intravenous thrombolysis, efforts should be made to control the extent of blood pressure reduction. When the blood pressure drops below 180/100 mmHg, antihypertensive treatment should be terminated. Twenty-four hours later, the routine blood pressure management protocol should be reinstated.
