1) Out-of-hospital sudden cardiac death (SCD) remains a major public health challenge, with over 400,000 cases per year in the United States. 2) While there is evidence of slight declines in pre-hospital delay times and more in-hospital treatment, over 60% of cardiac deaths continue to be sudden and outside of a hospital setting. 3) Improving early recognition of heart attack symptoms and rapid intervention through public health initiatives focused on out-of-hospital screening and treatment of patients with cardiac chest discomfort could help reduce the number of sudden cardiac deaths.
