Coronavirus disease pandemic impact on emergency department visits for cardiovascular disease in Korea: A review.

The coronavirus disease (COVID-19) pandemic has affected patient visits to the hospital, including visits to the emergency department (ED). This study aimed to analyze the impact of the COVID-19 pandemic on the patterns of ED visits and treatment in hospitals for diseases requiring urgent diagnosis and treatment. We analyzed entries from the South Korea National Emergency Department Information System claims database between January 1, 2018 and December 31, 2020. We analyzed data of patients who visited the ED with acute myocardial infarction (AMI), acute ischemic stroke (AIS), and acute hemorrhagic stroke (AHS). We found that the COVID-19 pandemic had impacted ED utilization and fatality in patients with AMI, AIS, and AHS.
