To improve the prognosis in patients with acute myocardial infarction (AMI) if treatment by early instituting treatment, we initiated a media campaign during 1 year with the intention to reduce delay times and increase ambulance use in patients with acute chest pain. This article describes the outcome during 3 years after the campaign was finished. The median delay time in patients with AMI was reduced from 3 hours 0 min before the campaign to 2 hours 20 minutes during the year of the campaign (P < .001). The median delay time remained at a similar level (2 hours 20 min) during the 3 years after the campaign. Ambulance use was not affected during or after the campaign. It can be concluded that a media campaign resulted in a reduction of delay times not only during the campaign, but also during 3 years after its performance, whereas ambulance use was not affected.
为了通过早期开展治疗来改善急性心肌梗死（AMI）患者的预后，我们在1年的时间里开展了一场媒体宣传活动，目的是减少延迟时间，并增加急性胸痛患者对救护车的使用。本文描述了宣传活动结束后3年的结果。AMI患者的中位延迟时间从宣传活动前的3小时0分钟减少到宣传活动当年的2小时20分钟（P <.001）。宣传活动后的3年里，中位延迟时间保持在相似水平（2小时20分钟）。宣传活动期间及之后，救护车的使用情况未受影响。可以得出结论，一场媒体宣传活动不仅在活动期间，而且在活动开展后的3年里都使延迟时间有所减少，而救护车的使用情况未受影响。
