The association of mode of location activity and mobility with acute coronary syndrome : a nationwide ecological study
Background We aimed to study the effect of social containment mandates on ACS presentation during COVID-19 pandemic using location activity and mobility data from mobile phone map services. Methods We conducted a cross-sectional study using data from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) including all ACS presentations during the pandemic until 7 May 2020. Using a count regression model, we adjusted for day of the week, daily weather and incidence of COVID-19. Results A 10% increase in activity around areas of residence was associated with 38% lower rates of ACS hospitalizations, whereas increased activity relating to retail and recreation, grocery stores and pharmacies, workplaces and mode of mobility was associated with 10-20% higher rates of ACS hospitalizations. Conclusion Government policy regarding social containment mandates has important public health implications for medical emergencies such as ACS and may explain the decline in ACS presentations observed during COVID-19 pandemic. ; Funding Agencies|Knut and Alice Wallenberg FoundationKnut & Alice Wallenberg Foundation Funding Source: Medline; Swedish Heart and Lung FoundationSwedish Heart-Lung Foundation Funding Source: Medline; Swedish Scientific Research CouncilSwedish Research Council Funding Source: Medline; ALF Funding Source: Medline; SSF (TOTAL-AMI) Funding Source: Medline; Bundy Academy Funding Source: Medline; Skane University Hospital Funds Funding Source: Medline; Marta Funding Source: Medline
