Abstract
The clinical entities that comprise acute coronary syndromes (ACS)—ST-segment elevation myocardial infarction (STEMI), non-STEMI, and unstable angina—have been recognized as widespread causes of death and disability for more than a century. Seminal research in the past 50 years has led to important scientific and medical advances in our understanding of ACS. Rapid modernization of the developing world has led to a pandemic of coronary artery disease and its manifestation as ACS, with profound implications for personal, societal, and global health. Epidemiological studies have provided insight into the changing demographics of ACS, and highlighted the importance of modifiable risk factors and adherence to guideline-recommended therapy.
Key Points
-
The prevalence of acute coronary syndromes (ACS) has reached a pandemic level as a consequence of modernization of the developing world
-
The demographics of ACS have evolved, with a precipitous decline in the incidence of ST-segment elevation myocardial infarction (STEMI) and a progressive rise in the incidence of non-STEMI
-
Modifiable risk factors account for >90% of the risk of myocardial infarction
-
Cardiac mortality has declined steadily over the past 50 years
-
Improvement in outcomes after ACS reflects increased adoption and utilization of evidence-based therapies, although racial, ethnic, and socioeconomic differences in care still exist
-
Epidemiological surveillance and population-based studies will be essential to evaluate the successful translation of evidence-based medicine into clinical practice
