About this study
Official title: Clinical Diagnosis and Treatment of Intracerebral Hemorrhage Based on Artificial
The purpose of this study is to test the reliability and validity of an artificial intelligence system and a related 5-score scale to predict hematoma expansion, and conduct a study cohort of intracerebral hemorrhage to screen out imaging and biological markers that could predict hematoma expansion in real-world.
Read the detailed description
This is a investigator-initiated, multi-center, prospective, registered cohort study. The study is intended to enroll 4000 patients with intracerebral hemorrhage from 50 hospital in China. Clinical and imaging data, as well as the results of laboratory examination will be collected to test the reliability and validity of an artificial intelligence system and a related 5-score scale to predict hematoma expansion, and conduct a study cohort of intracerebral hemorrhage to screen out imaging and biological markers that could predict hematoma expansion in real-world.

What is being measured
The primary outcome is the main question the study is designed to answer.
hematoma expansion

Measured: 24-48 hours from symptom onset
Recurrence of intracerebral hemorrhage
non-contrast CT scan: non-traumatic intracerebral hemorrhage other than the primary hemotoma
Measured: 90 days from symptom onset
Functional dependence
modified Rankin Scale score ≥3 (a global measure of disability on a seven-level scale, with scores ranging from 0 (no symptoms) to 6 (death), higher scores mean a better or worse outcome )
Measured: 3 months
Cerebrovascular death
Death due to one of the following events: ischemic stroke or hemorrhagic stroke
Measured: 3 months
Cardiovascular death
Death due to one of the following events: sudden cardiac death or acute myocardial infarction or heart failure
Measured: 3 months
Secondary outcomes (3)
New ischemic stroke
Acute focal neurological impairment corresponding with infarction on CT/MR scan
Measured: 3 months
New subarachnoid hemorrhage
Hemorrhage in subarachnoid space proven on CT/MR scan

Questions about this trial
What is this clinical trial studying?
An observational study of Intracerebral Hemorrhage, run by Beijing Tiantan Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
hematoma expansion (time frame: 24-48 hours from symptom onset). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2023; AzTrials last refreshed its copy on 8 Nov 2026.
