The impact of COVID-19 on the burden of cardiovascular diseases (CVD) during the early pandemic remains unclear. COVID-19 has become one of the leading causes of global mortality, with a disproportionate impact on persons with CVD. Studies of health facility admissions for CVD found significant decreases during the pandemic. Studies of hospital mortality for CVD were more variable. Studies of population-level CVD mortality differed across countries, with most showing decreases, although some revealed increases in deaths. In some countries where large increases in CVD deaths were reported in vital registration systems, misclassification of COVID-19 as CVD may have occurred. Taken together, studies suggest heterogeneous effects of the COVID-19 pandemic on CVD without large increases in CVD mortality in 2020 for a number of countries. Clinical and population science research is needed to examine the ways in which the pandemic has affected CVD burden.

COVID-19 在大流行早期对心血管疾病 (CVD) 负担的影响尚不清楚。 COVID-19 已成为全球死亡的主要原因之一，对 CVD 患者的影响尤为严重。对医疗机构因心血管疾病入院的研究发现，在大流行期间，该机构的入院人数显着下降。关于心血管疾病住院死亡率的研究变化较大。各国对人群心血管疾病死亡率的研究有所不同，大多数研究显示死亡人数有所下降，但也有一些研究显示死亡人数有所增加。在一些人口动态登记系统报告 CVD 死亡人数大幅增加的国家，可能发生了将 COVID-19 错误分类为 CVD 的情况。综上所述，研究表明，2020 年许多国家的 CVD 死亡率并未大幅增加，但 COVID-19 大流行对 CVD 产生了异质性影响。需要进行临床和人口科学研究来研究大流行对心血管疾病负担的影响方式。
