Hospitalizations for acute myocardial infarction (AMI) and stroke declined nationwide among adults during the early COVID-19 period, suggesting some patients did not receive timely care for these emergencies.^1-4 Declines in AMI and stroke hospitalizations might be particularly large for Medicare patients who, because they are older or physically disabled and have more comorbidities, are both more likely to have cardiovascular events and have concerns about contracting COVID-19 during a hospitalization. However, to our knowledge, no studies have examined this population specifically to date. We compared weekly rates of hospital use for AMI and stroke in 2020 with weekly rates in 2018 and 2019 among Medicare fee-for-service (FFS) beneficiaries nationally.

在 COVID-19 早期，全国成人急性心肌梗塞 (AMI) 和中风住院率有所下降，这表明一些患者没有得到及时治疗这些紧急情况。^{1 -4}对于医疗保险患者来说，AMI 和中风住院率的下降可能特别大，因为他们年龄较大或身体残疾并且有更多的合并症，他们更有可能发生心血管事件并且担心在住院期间感染 COVID-19。然而，据我们所知，迄今为止还没有研究专门检查过这一人群。我们比较了 2020 年 AMI 和中风的每周医院使用率与 2018 年和 2019 年全国医疗保险按服务收费 (FFS) 受益人的每周使用率。
