A two-year population study in the district of Prague 4 (population 190 000) showed that patients with acute myocardial infarction [AMI] came to the hospital with a considerable delay (median 10.25 hours), whose substantial part was caused by the patient's lingering in calling for medical aid (a half of them called as late as within 3 hours since the appearance of symptoms). On the other hand, out of 226 cases of sudden death caused by ischaemic heart disease (IHD), 92% of the victims died as early as within the first hour. Within the first hour, 27% of all patients with coronary attacks in the community died, and as a few as 2% only were hospitalized within this period. No prevention of sudden coronary death is possible for the time being. Nevertheless, an attempt can be made at least to reduce the risk of early death in the following two ways. The public shoudl be avised of the gravity of characteristic symptoms of AMI, danger in the case of delay, and necessity of prompt medical aid. Because a majority of victims of sudden death have positive histories of IHD, and most deaths occur in the patients' homes in the presence of their family members, these next relatives of patients with manifest IHD should be trained in the performance of cardiopulmonary resuscitation.
在布拉格4区（人口19万）进行的一项为期两年的人群研究表明，急性心肌梗死（AMI）患者前往医院就诊时存在相当长的延迟（中位数为10.25小时），其中很大一部分原因是患者在呼救时拖延（一半患者在症状出现后3小时才呼救）。另一方面，在226例由缺血性心脏病（IHD）导致的猝死病例中，92%的受害者早在发病后1小时内就死亡了。在社区中，所有冠心病发作患者中有27%在发病后1小时内死亡，而在此期间只有2%的患者住院治疗。目前还无法预防冠状动脉猝死。然而，至少可以尝试通过以下两种方式降低早期死亡的风险。应该告知公众急性心肌梗死特征性症状的严重性、延迟就医的危险性以及及时就医的必要性。由于大多数猝死受害者有缺血性心脏病的病史，而且大多数死亡发生在患者家中且有其家人在场的情况下，因此应该对患有明显缺血性心脏病患者的这些近亲进行心肺复苏术操作培训。
