In 1989 the National Heart Foundation (NHF) of Australia's Heart Week campaign was directed towards encouraging those with symptoms of possible myocardial infarction (MI) to seek help as promptly as possible. To evaluate its effect, three surveys were conducted of patients admitted to 22 coronary care units (CCUs). Two (335 and 221 patients) preceded and one (253 patients) followed the public education campaign. During the third survey a subset of patients were asked why they delayed, how long they thought one should wait before seeking help, whether they were aware of the media campaign and whether this had influenced their behaviour. Overall, only 42% of 809 patients sought help within one hour (median delay 1.2 hours). The median time of arrival and the proportion of patients arriving within one, two and four hours was not altered after this campaign. Those who admitted to having been aware of the campaign sought help no more promptly. The Heart Week campaign could not be shown to have produced any clinically important change in patient delay. Future campaigns will need to be modified in the light of this experience.
1989年，澳大利亚国家心脏基金会（NHF）的心脏周活动旨在鼓励那些有心肌梗死（MI）可能症状的人尽快寻求帮助。为评估其效果，对入住22个冠心病监护病房（CCU）的患者进行了三项调查。在公众教育活动之前进行了两项调查（分别涉及335名和221名患者），之后进行了一项调查（涉及253名患者）。在第三次调查中，一部分患者被问及他们拖延的原因、他们认为应该等待多长时间再寻求帮助、他们是否知晓媒体宣传活动以及这是否影响了他们的行为。总体而言，809名患者中只有42%在一小时内寻求帮助（中位延迟时间为1.2小时）。此次活动后，患者到达的中位时间以及在一小时、两小时和四小时内到达的患者比例均未改变。那些承认知晓该活动的患者寻求帮助的速度并没有更快。无法证明心脏周活动在患者延迟方面产生了任何具有临床重要意义的变化。未来的活动需要根据这一经验进行调整。
