The aim of this study was to evaluate the impact of the COVID-19 pandemic lockdown on acute myocardial infarction (AMI) care, and to identify underlying stressors in the German model region for complete AMI registration. The analysis was based on data from the population-based KORA Myocardial Infarction Registry located in the region of Augsburg, Germany. All cases of AMI (n = 210) admitted to one of four hospitals in the city of Augsburg or the county of Augsburg from February 10th, 2020, to May 19, 2020, were included. Patients were divided into three groups, namely pre-lockdown, strict lockdown, and attenuated lockdown period. An additional survey was conducted asking the patients for stress and fears in the 4 weeks prior to their AMI. The AMI rate declined by 44% in the strict lockdown period; in the attenuated lockdown period the rate was 17% lower compared to the pre-lockdown period. The downward trend in AMI rates during lockdown was seen in STEMI and NSTEMI patients, and independent of sex and age. The door-to-device time decreased by 70–80% in the lockdown-periods. In the time prior to the infarction, patients felt stressed mainly due to fear of infection with Sars-CoV-2 and less because of the restrictions and consequences of the lockdown. A strict lockdown due to the Covid-19 pandemic had a marked impact on AMI care even in a non-hot-spot region with relatively few cases of COVID-19. Fear of infection with the virus is presumably the main reason for the drop in hospitalizations due to AMI.

本研究的目的是评估 COVID-19 大流行封锁对急性心肌梗死 (AMI) 护理的影响，并确定德国模型区域中完整的 AMI 注册的潜在压力源。该分析基于位于德国奥格斯堡地区的基于人群的 KORA 心肌梗死登记处的数据。所有 AMI 病例 ( n = 210) 包括在 2020 年 2 月 10 日至 2020 年 5 月 19 日期间在奥格斯堡市或奥格斯堡县的四家医院之一住院的患者。患者被分为三组，即锁定前、严格锁定和缓和锁定期。进行了一项额外的调查，询问患者在 AMI 前 4 周内的压力和恐惧。AMI 率在严格封锁期间下降了 44%；在缓和封锁期间，该比率比封锁前低 17%。在 STEMI 和 NSTEMI 患者中观察到锁定期间 AMI 率的下降趋势，并且与性别和年龄无关。在锁定期间，从门到设备的时间减少了 70-80%。在梗塞前的时间里，患者感到压力主要是因为害怕感染 Sars-CoV-2，而不是由于封锁的限制和后果。即使在 COVID-19 病例相对较少的非热点地区，由于 Covid-19 大流行而导致的严格封锁也对 AMI 护理产生了显着影响。对感染病毒的恐惧大概是 AMI 住院人数下降的主要原因。
