Objective To strengthen the management of emergency treatment for patients with Acute Myocardial Infarction (AMI), and to shorten their treatment time. Methods Based on the present existing hospital information system and PDA, the emergency treatment and management system for AMI patients was developed to realize the intelligent monitoring of the whole rescue process. Then the system was applied to 75 AMI patients (experimental group) admitted in 2019, and compared with the 84 AMI patients (control group) admitted in 2018. Results The door-to-balloon time and the whole rescuing time of the experimental group were significantly shorter than those of the control group（P<0.01 for both）. After the application of the system, the complete implementation rate of the rescue path in the experimental group was 86.67%, and medical staff′s satisfaction on using the system reached 93.33%. Conclusion The emergency treatment and management system for AMI patients based on PDA, can standardize the diagnosis and treatment process, realize the scientific management of patients′ rescue process, shorten the door-to-balloon time effectively, and it is conducive to improving the rescue efficiency.
