To describe the benefits and pitfalls of educational campaigns designed to reduce the delay between the onset of acute myocardial infarction (AMI) and its treatment.
All seven educational campaigns reported between 1982 and 1994 were evaluated.
The impact on delay time ranged from a reduction of patient decision time by 35% to no reduction. One study reported a sustained reduction that resulted in the delay time being halved during the three years after the campaign. The use of ambulances did not increase. Only one study reported that survival was unaffected. There was a temporary increase in the numbers of patients admitted to the emergency department with non-cardiac chest pain in the initial phase of educational campaigns.
The challenge of shortening the delay between the onset of infarction and the start of treatment remains. The campaigns so far have not been proved to be worthwhile and it is not certain that further campaigns will do better. New media campaigns should be run to establish whether a different type of message is more likely to change the behaviour of people in this life-threatening situation.
描述旨在减少急性心肌梗死（AMI）发作与其治疗之间延迟的教育活动的益处和缺陷。
对1982年至1994年间报道的所有七项教育活动进行了评估。
对延迟时间的影响范围从患者决策时间减少35%到没有减少。一项研究报告称有持续减少，导致活动开展后的三年里延迟时间减半。救护车的使用没有增加。只有一项研究报告称生存率未受影响。在教育活动的初始阶段，因非心源性胸痛而入住急诊科的患者数量有短暂增加。
缩短梗死发作与治疗开始之间延迟的挑战依然存在。迄今为止，这些活动尚未被证明是值得的，而且不确定进一步的活动是否会有更好的效果。应开展新媒体活动，以确定不同类型的信息是否更有可能改变处于这种危及生命情况的人们的行为。
