In the ACC and AHA guidelines for the four stages of heart failure, which of
the stages is defined as: patient at high risk for development of heart failure
but has no apparent structural abnormality of the heart.

Select one:
a. Stage A
b. Stage B
c. Stage C
d. Stage D

The correct answer is: Stage A

A 67 year old male with class III heart failure, an EF of 32% and a QRS of
140ms is implanted with a CRT-D device. Remote follow-up detects some
bouts of paroxysmal atrial fibrillation (AF) at the nine month period. The
patient is then seen in the device clinic and diagnostics indicate the AF burden
to be 8%. The patient states that he is asymptomatic.
Which of the following would be most appropriate for this patient?

Select one:
a. Continue to monitor the patient before intervention
b. Start the patient on aspirin
c. Start the patient on sotalol (Betapace or Betapace AF)
d. Start the patient on dabigatran or rivaroxaban and consider turning on an
atrial overdrive pacing algorithm

The correct answer is: Start the patient on dabigatran or rivaroxaban and consider
turning on an atrial overdrive pacing algorithm
