Awareness of heart attack symptoms and the need to call 9-1-1 has improved among U.S. adults from 2008 to 2017, though disparities persist.
Fang et al. (2019) conducted a cross-sectional in Awareness of heart attack symptoms (n=84,294). Survey year (2017) vs. Survey year (2008) was evaluated on Awareness of all five common heart attack symptoms (10.6 percentage point increase, p=<0.001). Awareness of all five common heart attack symptoms among U.S. adults increased significantly from 39.6% in 2008 to 50.2% in 2017, though sociodemographic disparities persisted.
