Which organization is the source for Advanced Cardiovascular Life Support guidelines?

• A. American Heart Association
• B. American College of Cardiology
• C. International Society on Thrombosis and Haemostasis
• D. National Institute of Health

Answer: (A)

ACLS guidelines come from the American Heart Association, which oversees the development and publication of standardized resuscitation protocols used in both prehospital and in-hospital settings. They base updates on the latest evidence and coordinate with the International Liaison Committee on Resuscitation for international consensus, but the official source and publisher of the ACLS guidelines is the American Heart Association. The other organizations listed focus on different areas—ACC on cardiovascular disease treatment broadly, ISTH on thrombosis and hemostasis, and NIH as a government research body—so they aren’t the source of ACLS guidelines.
