The Authors intended to verify if in a CCU in a Hospital in a country town, the precoronary times were different from those pointed out in the series of cases relatives to the Hospitals of a big town and if the possible remark of different times is liable to be translated into different epidemiologic results. The remarks have been effected on 80 patients affected by acute myocardial infarction; the average of the precoronary time resulted into 13h,43', slightly lower than that observed in the other Hospitals in Lazio. Particularly the 27,5% of the patients was admitted into the Hospital within one hour from the onset of their symptoms and the 65% within six hours, which shows an hospitalization in the very early period. Though in this group dangerous arrhythmias (ventricular fibrillation included) have been observed frequently, it has not been remarked a mortality greater than in other series of cases, and explains the high mortality for arrhythmia observed in our series of cases (21,4% of all deaths), considering the high frequency of dangerous arrhythmias (V.F. included) noticed in the first hours of myocardial infarction.
作者旨在验证在一个乡村小镇医院的冠心病监护病房（CCU）中，冠心病发作前时间是否与大城市医院系列病例中指出的时间不同，以及不同时间的可能差异是否会转化为不同的流行病学结果。对80例急性心肌梗死患者进行了观察；冠心病发作前时间的平均值为13小时43分，略低于拉齐奥其他医院观察到的时间。特别是27.5%的患者在症状发作后1小时内入院，65%在6小时内入院，这表明是在非常早期进行的住院治疗。尽管在该组中经常观察到危险心律失常（包括心室颤动），但并未发现死亡率高于其他系列病例，考虑到在心肌梗死最初几小时内发现危险心律失常（包括室颤）的频率较高，这就解释了我们系列病例中观察到的心律失常高死亡率（占所有死亡病例的21.4%）。
