About this study

This study applied an application that provides individualized environmental temperature-related health risk warnings and recommendations to stroke patients, enabling them to promptly understand their risk levels and take corresponding protective measures. And explore the effect of this actual intervention on reducing the risk of stroke recurrence after one year, as well as changes in other health-related indicators.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Aged 40 to 80, with no gender restrictions;
  • Acute ischemic stroke inpatients within 2 weeks of onset, where the onset time is the time when stroke symptoms appear or the last known normal time of the patient (when it is an onset during sleep or the symptom onset time cannot be accurately obtained due to aphasia, impaired consciousness, etc.);
  • Confirmed diagnosis of ischemic stroke by CT or MRI of the brain within 2 weeks after symptom onset;
  • Local residents (residing for ≥6 months); ⑤ Patients who voluntarily participate in the study, have high compliance, and can sign the informed consent form;
  • Patients who own a smartphone or other smart devices.

Exclusion criteria

  • Patients diagnosed with other cerebrovascular diseases (hemorrhagic stroke, transient ischemic attack, cerebral venous sinus thrombosis, etc.) or non-cerebrovascular diseases;
  • Known pregnant or lactating women, or those who tested positive on a pregnancy test before cluster randomization;
  • Patients with other conditions that may affect participation in the trial (e.g., refractory hypertension, severe aphasia, etc.);
  • Patients undergoing psychiatric/psychological treatment that may contaminate the results; ⑤ Patients with a life expectancy of less than one year (e.g., coexisting malignant tumors, severe cardiopulmonary diseases, etc.); ⑥ Patients already participating in other interventional clinical studies that may influence the outcome assessment; ⑦ Patients for whom the investigator deems unsuitable for participation in this study or who may pose significant risks to the patients (e.g., cognitive impairment preventing understanding and/or compliance with the study procedures and/or follow-up).

Primary outcomes

  1. 1-year recurrence rate of stroke

    Time frame: Intervention at the 1-year

Secondary outcomes

  1. 3-month, 6-month, 9-month recurrence rate of stroke

    Time frame: Intervention at 3-month, 6-month, 9-month

  2. Blood pressure

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    Systolic and diastolic blood pressure will be measured using a standard automated sphygmomanometer

  3. Electrocardiogram (ECG) parameters

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    Electrocardiogram (ECG) will be performed to assess cardiac electrical activity. Specific parameters will be analyzed, such as heart rate (beats per minute (bpm)), QT interval (milliseconds (ms)), PR interval (milliseconds (ms)), QRS duration (milliseconds (ms))

  4. Environmental temperature health risk perception assessment questionnaire

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    It is used to assess patients' understanding and concern about health hazards related to temperature. The lower the score, the less they understand or are concerned about it

  5. System usability scale score

    Time frame: Intervention at 3-month, 6-month, 9-month and 1-year

    It is used to understand the subjects' satisfaction and usability evaluation of the intelligent program. The higher the score, the better the evaluation

  6. Lipid Profile (Total Cholesterol, LDL-C, HDL-C, and Triglycerides)

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    Plasma lipid levels will be measured using standard laboratory assays, including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG).

  7. Fasting blood glucose

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    Fasting plasma glucose levels will be measured to assess glycemic control.

  8. Coagulation parameters (Prothrombin Time, aPTT, INR, Fibrinogen, Platelet Count and D-dimer)

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    Coagulation status will be assessed using standard coagulation tests, including prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalized ratio (INR), fibrinogen level, platelet count and D-dimer.

  9. C-reactive protein

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    Blood samples will be analyzed using immunoassay techniques on automated analyzers

  10. Modified rankin scale score

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    The functional recovery of patients was evaluated using the modified rankin scale. The higher the score, the more serious it is

  11. NIH stroke scale score

    Time frame: Baseline

    The neurological deficits on the NIHSS scale indicate that the higher the score, the more severe the stroke

  12. European five-dimensional five-level health scale score

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    It is used to assess an individual's health-related quality of life, consisting of two parts: a questionnaire and a visual analog scale (VAS). The questionnaire includes five dimensions, where higher scores indicate worse health status. The visual analog scale asks respondents to rate their overall health on a 0-100 scale, with higher scores reflecting better self-rated health status.

  13. Minimum mental state examination

    Time frame: Baseline; Intervention at 6-month and 1-year

    It is used to screen patients' cognitive conditions. The lower the score, the worse the cognition

  14. Social support rate scale score

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    It is used to understand the support that patients receive in society, and the higher the score, the more support they receive

  15. Depression anxiety stress scales - 21 score

    Time frame: Baseline; Intervention at 3-month, 6-month, 9-month and 1-year

    It is used to understand the patient's emotional state. The higher the score, the worse the mood

Other outcomes

  1. Incidence of adverse cerebrovascular events

    Time frame: Intervention at the 1-year
