Update on application and research progress of large⁃scale medical database in stroke

With rapid aging worldwide, stroke disease has become the second leading cause of death in people over 60 years old, following the cancer disease. The large⁃scale medical database provides epidemiological data by systematically integrating medical data and transforming research hypotheses into evidence⁃based medicine evidence to guide clinical practice, widely used in clinical medical research. This article describes different stroke databases to explain their application and research progress in stroke diseases, and describes the application of artificial intelligence (AI) in database construction, aiming to promote the construction of stroke databases and conduct high⁃quality stroke research. doi：10.3969/j.issn.1672⁃6731.2021.03.004
