Gedetailleerde beschrijving
Within 24 hours after symptom onset, eligible participants will be randomly assigned in a 1:1 ratio to the HUK or placebo group, receiving adjunctive HUK or placebo treatment alongside standard intravenous thrombolysis and/or endovascular treatment. All participants will be recommended to continuously inject drugs or placebo for 10 to 14 days according to length of hospitalization.
- Intervention group: HUK (0.15 PNA) and sodium chloride injection (100ml), once per day
- Control group: placebo (0 PNA) and sodium chloride injection (100ml), once per day The total follow-up duration is 90 days.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Proportion of a favorable outcome (mRS 0-2)
Tijdsspanne: at 90 days
|
The proportion of a favorable outcome, defined by a modified Rankin Scale (mRS) score ranging from 0 to 2, reflects the percentage of patients who attained a functional status from no symptoms to mild disability, enabling them to perform all pre-stroke activities without assistance. |

|
Proportion of a favorable outcome (mRS 0-2)
Tijdsspanne: at 14 days
|
The proportion of a favorable outcome, defined by a modified Rankin Scale (mRS) score ranging from 0 to 2, reflects the percentage of patients who attained a functional status from no symptoms to mild disability, enabling them to perform all pre-stroke activities without assistance. |

|
|
Proportion of an excellent outcome (mRS 0-1)
Tijdsspanne: at 90 days
|
The proportion of an excellent outcome, characterized by a modified Rankin Scale (mRS) score of 0 to 1, represents the percentage of patients who achieved a functional status from no symptoms to no significant disability despite symptoms, allowing them to resume all pre-stroke activities without any aid. |
at 90 days
|
|
Distribution of mRS score
Tijdsspanne: at 90 days
|
The distribution of modified Rankin Scale (mRS) scores provides a comprehensive overview of the functional outcomes across a patient population, categorizing the degree of disability from no symptoms (score 0) to severe disability or death (score 6). |
at 90 days
|
|
Improvement of NIHSS score
Tijdsspanne: at 14 days
|
The improvement of the National Institutes of Health Stroke Scale (NIHSS) score serves as a quantifiable measure of neurological recovery, reflecting the reduction in stroke-related deficits and the enhancement of patient functional capabilities over time. Minimum Score: 0 (no stroke symptoms) Maximum Score: 42 (severe stroke) Higher NIHSS scores indicate more severe stroke symptoms and are associated with worse outcomes.Lower NIHSS scores indicate milder stroke symptoms and are associated with better outcomes. |
at 14 days
|
|
Risk of recurrent symptomatic stroke
Tijdsspanne: within 90 days
|
The risk of recurrent symptomatic stroke quantifies the probability of a subsequent stroke event with clinical manifestations, providing a critical measure for assessing the long-term efficacy of stroke prevention strategies and the ongoing vulnerability of the patient population. |
within 90 days
|
|
Risk of recurrent symptomatic ischemic stroke
Tijdsspanne: within 90 days
|
The risk of recurrent symptomatic ischemic stroke delineates the likelihood of a subsequent ischemic stroke event accompanied by clinical symptoms, serving as a pivotal indicator for evaluating the effectiveness of secondary prevention measures and the persistent threat of cerebral ischemia in affected individuals. |
within 90 days
|
|
Risk of combined vascular events
Tijdsspanne: within 90 days
|
The risk of combined vascular events encompasses the probability of experiencing any major vascular incident, such as stroke, myocardial infarction, or vascular death, offering a comprehensive metric for assessing the overall burden of vascular disease and the aggregate impact of therapeutic interventions on cardiovascular health. |
within 90 days
|
|
Improvement of EQ-5D-5L
Tijdsspanne: at 90 days
|
The improvement of EQ-5D-5L(EuroQol 5-Dimension 5-Level) reflects an enhancement in health-related quality of life, as measured by gains across five dimensions-mobility, self-care, usual activities, pain/discomfort, and anxiety/depression-on a five-level severity scale, indicating a positive shift in the patient's overall health state and well-being. Minimum Score: 0 (worst imaginable health state) Maximum Score: 100 (best imaginable health state) For the descriptive system, a lower score (closer to 11111) indicates better health-related quality of life, while a higher score (closer to 55555) indicates worse health-related quality of life. For the VAS, a higher score (closer to 100) indicates better self-rated health, while a lower score (closer to 0) indicates worse self-rated health. |
at 90 days
|
|
Improvement of MOCA
Tijdsspanne: at 90 days
|
The improvement of the Montreal Cognitive Assessment (MoCA) score signifies an enhancement in cognitive function, encompassing domains such as attention, memory, language, and executive functions, thereby indicating a positive progression in the patient's cognitive status and potential recovery from cognitive impairment. Minimum Score: 0 (severe cognitive impairment) Maximum Score: 30 (no cognitive impairment) Higher MoCA scores indicate better cognitive function. Lower MoCA scores indicate worse cognitive function. |
