Societal lockdowns during the first wave of the coronavirus disease 2019 pandemic were associated with decreased admission rates for acute cardiovascular conditions worldwide. In this nationwide Danish study of the first five weeks of a second pandemic lockdown, incidence of new-onset heart failure and atrial fibrillation remained stable, but there was a significant drop in new-onset ischemic heart disease and ischemic stroke during the fourth week of lockdown, which normalized promptly. The observed drops were lower compared to the first Danish lockdown in March 2020; thus, our data suggest that declines in acute cardiovascular disease admission rates during future lockdowns are avoidable.

第二次 COVID-19 封锁期间的全国心血管疾病入院率。

2019 年第一波冠状病毒病大流行期间的社会封锁与全球急性心血管疾病的入院率下降有关。在丹麦对第二次大流行封锁的前五周进行的这项全国性研究中，新发心力衰竭和心房颤动的发病率保持稳定，但在第 4 周新发缺血性心脏病和缺血性中风的发生率显着下降。锁定，迅速恢复正常。与 2020 年 3 月丹麦的第一次封锁相比，观察到的下降幅度较低；因此，我们的数据表明，未来封锁期间急性心血管疾病入院率的下降是可以避免的。
