Data collection and randomization
AMI, CHRONIC DISEASES
Clinical features of AMI patients were collected, which included demographics, history of chronic diseases, disease-related information, laboratory tests, and PCI-related information. After enrollment, all patients were randomly assigned into the CBSM or control care (CC) groups using a 1:1 ratio. The randomization was conducted by the block randomization method (bloke size = 4). Random grouping information for each patient was sealed in an opaque envelope, and which patient’s ID was written on the cover. In chronological order of patient enrollment, the patient was given the opaque envelope and allocated to two different groups.
