Coronary disease & ACS

Incidence of sudden cardiac arrest and sudden cardiac death after unstable angina pectoris and myocardial infarction

Am Heart JPublished Retrospective cohort study

Authors' conclusion

SCAs accounted for less than a third of all deaths due to cardiovascular causes among patients with previous ACS. Incidence of SCA is highest among STEMI and NSTEMI patients. After the hospital discharge, most of SCAs happen to NSTEMI patients.
