About this study

Official title: A Prospective Cohort Study of Predictors and Prognostic Factors on the Acute Ischemic Stroke

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Drug TherapyDrug

    Also called Aspirin, Clopidogrel, Statin

    For this observation research, anti platelet drugs, statins and ect. would be used as clinical guidelines as usal, and statical ananysis of the relationship between these drugs and the final outcomes

  • Routine Blood Test and Image ScanDiagnostic test

    Routine blood test(HCY, LDL and ect.) and image scan (DWI, DSA and ect.)

  • Intravascular therapyOther

    Intravascular therapy including thrombectomy

  • Emergency TreatmentOther

    Emergency treatment including time to self-diagnosis of stroke, time to call for help, devices used to hospital and ect.

  • Medical historyOther

    Medical history including hypertension, diabetes, hyperlipemia and ect.

Study groups in NCT03122002
Study groupRoleWhat they receive
Patients With Ischemic StrokeThe 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.
Receives: Drug: Drug Therapy; Diagnostic Test: Routine Blood Test and Image Scan; Other: Intravascular therapy; Other: Emergency Treatment; Other: Medical history
Healthy ControlThe 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.
Receives: Diagnostic Test: Routine Blood Test and Image Scan; Other: Medical history

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: Change from Baseline mRS score at 24 months

Secondary outcomes (10)
  1. Re-admission to the hospital

    Re-admission to the hospital (patients without new symptoms and admitted to the hospital simply for physical examination are not counted)

    Measured: 24 months

  2. Cerebral and Cardio vascular diseases

    Cerebral and Cardio vascular diseases including small vessel diseases, white matter ischemia, micro hemorrhage, ischemic stroke and hemorrhagic stroke.

    Measured: 24 months

  3. Neurological deterioration-1

    Neurological deterioration (NIHSS score)

    Measured: Change from Baseline NIHSS score at 24 months

  4. Neurological deterioration-2

    Neurological deterioration (FAQ score)

    Measured: Change from Baseline FAQ score at 24 months

  5. Cognitive dysfunction

    Cognitive dysfunction (MMSE score). Patients with cognitive dysfunction will be classified into mild neurocognitive disorder, major neurocognitive disorder according to DSM-5

    Measured: Change from Baseline MMSE score at 24 months

  6. Cognitive dysfunction

    Cognitive dysfunction (MoCA score). Patients with cognitive dysfunction will be classified into mild neurocognitive disorder, major neurocognitive disorder according to DSM-5

  10. Severe pulmonary infection

    Severe pulmonary infection

    Measured: 24 months
