A primary challenge in the development of clinical practice
guidelines is keeping pace with the stream of new data on
which recommendations are based. In an effort to respond
promptly to new evidence, the American College of Cardiology
Foundation/American Heart Association (ACCF/AHA)
Task Force on Practice Guidelines (Task Force) has created a
“focused update” process to revise the existing guideline
recommendations that are affected by the evolving data or
opinion.
