Study summary

Through 5 years continuous observation of acute ischemic stroke patients in Neurology Department of Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, clinical data about emergency treatment (neurological score, examination and treatment), medical data after admission (neurological score, inspection, examination and treatment) and long-term prognosis (neurological score) was collected. The outcomes were set as the score scale, all blood test index and examination index of the research objects at specific period after illness. Through statistical analysis and comparison of different in-hospital clinical data in predicting the outcome of the patients, our study will provide more evidence-based solutions for the treatment and prediction of acute ischemic stroke.

Read the detailed description

The research is designed as registrated, prospective, open-labeled, blind-endpoint, and the research objects are continuously recorded. The final subgroups are blind to neurological evaluators, data inputers and statisticians.

The research is a continuous observational exploratory study. All patients with ischemic stroke admitted to Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology from April 1, 2017 to December 31, 2021 will be included. According to the current situation, it is expected to enroll approximately 5000 of eligible patients for long-term follow-up observation.

We'll use multiple linear regression analysis model to study factors and confounding factors and their interaction. And we will control the confounding factors, and make a quantitative description of the relationship between factors and outcome variables.

Missing cases will be treated as censored values, and the ratio of missing cases will be recorded. All samples will be analyzed by Intent-to-Treat (ITT) analysis. In the analysis, if the results are statistically significant, the missing cases in the exposed group will be deleted, and the missing cases in non-exposure group be added. If the results are still statistically significant, then the missing cases are defined as not affecting the analysis results.

If the heterogeneity of data is large, the objects will be analyzed in subgroups according to age or sex.

If the missing rate is greater than 20%, it is necessary to analyze the sensitivity of the whole sample.

Groups and cohorts

  • Patients With Ischemic Stroke

    The patients with all types of ischemic stroke including TIA, small vessle diseases, MCAO, and ect. These patients will be recorded their emergency treatment, medical history, details about their drug therapy, results of their routine blood test and image scan, and whether they receive intravascular therapy in time or not.

    Drug: Drug Therapy · Diagnostic Test: Routine Blood Test and Image Scan · Other: Intravascular therapy · Other: Emergency Treatment · Other: Medical history

  • Healthy Control

    The patients admitted to hospital for symptoms like dizzness and headache, which later proved to be not related to cerebral vascular diseases, would be treated as control. Their medical history and the results of their routine blood test and image scan will be recorded.

    Diagnostic Test: Routine Blood Test and Image Scan · Other: Medical history

What researchers measure

Primary outcomes

  1. Modified Rankin Scale scores

    0 = No symptoms; 1 = No significant disability. Able to carry out all usual activities, despite some symptoms; 2 = Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities; 3 = Moderate disability. Requires some help, but able to walk unassisted; 4 = Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted; 5 = Severe disability. Requires constant nursing care and attention, bedridden, incontinent; 6 = Dead.

    Time frame: Change from Baseline mRS score at 24 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 7, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
