Alteplase in Elderly Acute Ischemic Stroke (AIS) Patients During Hospitalization
Study Details
Study Description
Brief Summary
The objective of the study is to find out the in-hospital clinical outcomes among Chinese Acute Ischaemic Stroke (AIS) patients, who were treated with intravenous (IV) Recombinant Tissue Plasminogen Activator (rt-PA) within 4.5 hours of symptom onset in different age groups (18 to 80 years and above 80 years).

Outcome Measures
Primary Outcome Measures
- All-cause mortality during hospitalization [up to 3 months]
analyzed for patients in Group 1 and Group 2
Secondary Outcome Measures
- Proportion of patients with hemorrhagic stroke during hospitalization [up to 3 months]
analyzed for patients in Group 1 and Group 2
- Change of National Institutes of Health Stroke Scale (NIHSS) score from before IV rt-PA treatment to 24 hours after IV rt-PA treatment [baseline and 24 after IV rt-PA treatment]
analyzed for patients in Group 1 and Group 2 The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss. NIHSS scores range from 0 - 42. A score of 0 indicates no stroke symptoms. Higher scores indicate incremental levels of neurological impairment.
- modified Rankin Scale (mRS) score at discharge [up to 3 months]
analyzed for patients in Group 1 and Group 2 The modified Rankin Scale (mRS) is used for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. The scale runs from 0-6, from 'perfect health without symptoms' to 'death'. 0 - No symptoms. - No significant disability. Able to carry out all usual activities, despite some symptoms. - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities. - Moderate disability. Requires some help, but able to walk unassisted. - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted. - Severe disability. Requires constant nursing care and attention, bedridden, incontinent. - Dead.
- Proportion of patients with stroke recurrence during hospitalization [up to 3 months]
analyzed for patients in Group 1 and Group 2
- Length of hospitalization [up to 3 months]
analyzed for patients in Group 1 and Group 2
- Percentage of IV rt-PA treatment among AIS patients arrived or were admitted to the hospital within 4.5 hours of symptom onset [up to 3 months]
The percentage of IV rt-PA treatment will be calculated based on age groups (18-80 years and >80 years).
- Percentage of IV rt-PA treatment within 4.5 hours of symptom onset among eligible AIS patients (3.5-hour arrival or admission) [up to 3 months]
The percentage of IV rt-PA treatment will be calculated based on age groups (18-80 years and >80 years).
