A Multicenter Study Based on Multi-omics Analysis to Predict the Early Prognosis and Recurrence Risk of Acute Ischemic Stroke

any stroke /TIA/ myocardial infarction/Vascular death

Clinical investigators evaluate brain injury conditions according to head CT or MR, which including the signs of infarct lesions, hemorrhagic transformation post-infarction or cerebral edema.

Clinical investigators evaluate small vessel disease burden according to head CT or MR, which including the signs of white matter degeneration, lacunar infarctions, cerebral microbleeds or enlarged perivascular spaces.

Clinical investigators evaluate cerebrovascular pathology according to head CT or MR, which including the signs of vascular stenosis, vascular dissection or collateral circulation compensation.

The MRS score is primarily used to measure the degree of disability and daily living ability of patients. The MRS score ranges from 0 to 6, with a total of 7 levels. The higher the score, the more severe the disability and the worse the prognosis.

The NIHSS score is commonly used to assess the degree of neurological impairment in patients with acute stroke. The NIHSS consists of 11 items, with a total score ranging from 0 to 42. Each item has different scoring criteria, typically ranging from 0 (normal) to 4 (most severe).

The ADL score is primarily used to measure a person's ability to perform basic daily activities. This study uses the Barthel Index scoring method, which ranges from 0 to 100 points, with scoring items including eating, bathing, grooming, dressing, bowel control, bladder control, toileting, transferring, mobility and stairs. A higher score indicates greater independence, while a lower score indicates greater dependence.

The MMSE (Mini-Mental State Examination) is a tool used to assess cognitive function, including orientation, memory, attention, language skills, calculation ability, and visuospatial skills. It is commonly used to screen for dementia in older adults. The MMSE has a total score of 30 points: a score of 24-30 suggests normal cognitive function, 18-23 indicates mild cognitive impairment, and 0-17 indicates moderate to severe cognitive impairment.

The MoCA is a tool used to assess cognitive impairment. Compared to the MMSE, the MoCA is more sensitive, particularly for detecting mild cognitive impairment (MCI). The MoCA has a total score of 30 points: a score of 26-30 suggests normal cognitive function, 18-25 indicates mild cognitive impairment (MCI), and 0-17 indicates moderate to severe cognitive impairment. Typically, individuals with lower educational levels (less than 12 years of education) receive an additional point as an adjustment to their total score.

The HAMD is a clinical scale used to assess the severity of depression. This study uses the 17-item version (HAMD-17), which covers a range of symptoms, including mood, sleep, appetite, and somatic symptoms. The total score ranges from 0 to 52, with each item rated based on the severity of symptoms, typically from 0 (no symptoms) to 4 (severe symptoms).

The HAMA is a clinical scale used to assess the severity of anxiety symptoms. It consists of 14 items, each evaluating different symptoms related to anxiety. These symptoms cover both psychological and somatic manifestations of anxiety. Each item is rated based on the severity of symptoms, with scores ranging from 0 (no symptoms) to 4 (very severe symptoms).
