An Application That Can Provide Early Warning of Temperature Health Risks and Give Protective Suggestions or Personalized Suggestions Based on Patients' Own Secondary Prevention Risk Factors Was Applied to Intervene, and the Intervention Effect of APP on Stroke Recurrence Risk Was Analyzed

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.); ③ 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;

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).
