The American College of Cardiology Foundation (ACCF) is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. The ACCF designates this Journal-based CME activity for a maximum of 1 AMA PRA Category 1 Credit(s)!. Physicians should claim only the credit commensurate with the extent of their participation in the activity. Successful completion of this CME activity, which includes participa- tion in the evaluation component, enables the participant to earn up to 1 Medical Knowledge MOC point in the American Board of Internal Medicine’s (ABIM) Maintenance of Certification (MOC) program. Par- ticipants will earn MOC points equivalent to the amount of CME credits claimed for the activity. It is the CME activity provider’s responsibility to submit participant completion information to ACCME for the pur- pose of granting ABIM MOC credit.
