Post-COVID changes and disparities in cardiovascular mortality rates in the United States

Year: 2024

Type: article

Abstract: Introduction: The COVID-19 pandemic disrupted healthcare delivery and increased cardiovascular morbidity and mortality. This study assesses whether cardiovascular mortality rates in the US have recovered post-pandemic and examines the equity of this recovery across different populations. Methods: We analyzed data from the CDC WONDER database, covering US residents' mortality from 2018-2023. We focused on cardiovascular diseases, categorized by ischemic heart disease (IHD), heart failure (HF), hypertensive diseases (HTN), and cerebrovascular disease. Age-adjusted mortality rates were calculated for three periods: pre-COVID (2018-2019), during COVID (2020-2021), and post-COVID (2022-2023), stratified by demographic and geographic variables. Results: Cardiovascular age-adjusted mortality rates increased by 5.9% during the pandemic but decreased by 3.4% post-pandemic, resulting in a net increase of 2.4% compared to pre-COVID levels. When compared to pre COVID age-adjusted mortality rates, post COVID IHD mortality age-adjusted mortality rates decreased by 5.0%, while cerebrovascular and HTN age-adjusted mortality rates increased by 5.9% and 28.5%, respectively. Men and younger populations showed higher increases in cardiovascular Age-adjusted mortality rates. Geographic disparities were notable, with significant reductions in cardiovascular mortality in the Northeast and increases in states like Arizona and Oregon. Conclusion: The COVID-19 pandemic led to a surge in cardiovascular mortality, with partial recovery post-pandemic. Significant differences in mortality changes highlight the need for targeted healthcare interventions to address inequities across demographic and geographic groups.
