Eligibility
Inclusion criteria
Inclusion criteria: 1. In accordance with the expert consensus on imaging evaluation of intracranial atherosclerotic stenosis, intracranial large artery stenosis =50% confirmed by CTA, MRA or DSA; 2. 18 = age =80 years old; 3. No previous ischemic stroke or TIA event.
Exclusion criteria
Exclusion criteria: 1. Suspected atrial fibrillation, known prosthetic heart valve, suspected endocarditis, patent foramen ovale and other congenital heart disease; A history of myocardial damage within 30 days before enrollment, including myocardial infarction, myocarditis; 2.
