OBJECTIVE
To improve time to treatment, the effects of acute myocardial infarction (AMI) symptoms on prehospital delay time (PDT) were investigated.
METHODS
Patients with AMI completed a questionnaire on their AMI symptoms and their general knowledge of AMI symptoms.
RESULTS
In total, 116 patients completed questionnaires. The mean PDT was 7.3 ± 2.4 h; the median PDT was 2.2 h. Each patient experienced a mean of 3.6 symptoms during their AMI. PDT was significantly shorter in the following groups: patients with chest compression pain/chest discomfort, profuse sweating or dyspnoea than in patients with other symptoms; patients presenting with typical rather than atypical symptoms; patients with pain scores >6 compared with scores ≤6; patients who were aware rather than unaware of AMI symptoms. Patients actually having AMI symptoms and patients being aware of AMI symptoms were inversely correlated with PDT. There was a linear relationship between pain scores and PDT.
CONCLUSION
Public awareness of AMI symptoms should be enhanced, in order to shorten PDT and improve AMI survival rates.
目的
为了缩短治疗时间，研究急性心肌梗死（AMI）症状对院前延误时间（PDT）的影响。
方法
急性心肌梗死患者完成了一份关于其急性心肌梗死症状及对急性心肌梗死症状一般认识的调查问卷。
结果
共有116名患者完成了调查问卷。平均院前延误时间为7.3±2.4小时；中位数院前延误时间为2.2小时。每位患者在急性心肌梗死期间平均出现3.6种症状。以下几组患者的院前延误时间明显更短：有胸部压榨性疼痛/胸部不适、大汗淋漓或呼吸困难症状的患者，相较于有其他症状的患者；表现为典型症状而非非典型症状的患者；疼痛评分>6分的患者相较于评分≤6分的患者；意识到急性心肌梗死症状的患者相较于未意识到的患者。实际出现急性心肌梗死症状的患者以及意识到急性心肌梗死症状的患者与院前延误时间呈负相关。疼痛评分与院前延误时间之间存在线性关系。
结论
应提高公众对急性心肌梗死症状的认识，以缩短院前延误时间并提高急性心肌梗死的生存率。
