Objective To understand the status of pre-hospital delay behavior intention among high-risk patients of major adverse cardiac events (MACE) in the community, and to explore its influencing factors. Methods A total of 325 high-risk patients of MACE in the community were investigated using the Pre-hospital Delayed Behavior Intention Assessment Scale and the Major Adverse Cardiac Events Knowledge Questionnaire. Results The total score of Pre-hospital Delay Behavior Intention in the participants was (55.07±8.87), and the score of Major Adverse Cardiac Events Knowledge was 8.99(4.00, 10.00).Multiple regression analysis showed that, knowledge of MACE, educational background, personal monthly income and history of other diseases were indepen-dent influencing factors of pre-hospital delay behavior intentions in high-risk patients of MACE in the community (P＜0.05,P＜0.01). Conclusion The pre-hospital delay behavior intention in high-risk patients of MACE in the community is in a moderate level.It is necessary to pay attention to those high-risk patients with deficit MACE knowledge, low educational background, low income and multiple diseases, and conduct targeted health education and management, so as to reduce the pre-hospital delay behavior intention level.
