Time intervals between the onset of the presenting symptom (chest pain) and arrival in a coronary care unit were studied for 221 admissions arranged by conventional means. The median figure for "patient delay" was 60 minutes, for "general-practitioner delay" 20 minutes, for "ambulance delay" 30 minutes, and for "transit delay" 30 minutes. The median "total delay" was three hours 30 minutes.Only 4.5 per cent of the patients were under intensive coronary care within one hour, the time of the highest mortality risk. A mobile coronary service should be capable of increasing the proportion of patients brought under special care within the first hour, but the time taken by the patient to realise the nature of the emergency and summon aid is likely to remain the most critical factor.
对通过传统方式安排入院的221名患者，研究了出现症状（胸痛）至抵达冠心病监护病房之间的时间间隔。“患者延误”的中位数为60分钟，“全科医生延误”为20分钟，“救护车延误”为30分钟，“转运延误”为30分钟。“总延误”的中位数为3小时30分钟。在死亡风险最高的1小时内，只有4.5%的患者接受了强化冠心病护理。流动冠心病服务应能够提高在第一小时内接受特殊护理的患者比例，但患者认识到紧急情况的性质并呼救所花费的时间可能仍然是最关键的因素。
