17
Q

In order to diagnose Stable Angina, what should be performed first?

A

ECG and pretest probability of CAD

18
Q

In order to diagnose Stable Angina, if the pretest probability of CAD is intermediate, what are the 2 options for the patient?

A
  • If able to exercise = Exercise ECG and ECHO
  • If unable to exercise = Pharmacologic testing
    == BOTH: Coronary Angiography
19
Q

In order to diagnose Stable Angina, if the pretest probability of CAD is high, what is the next step?

A

Medical therapy and Coronary Angiography

22
Q

What does the Dobutamine ECHO evaluate?

A

Contractility

23
Q

What does a MPI (myocardial perfusion imaging) do?

A

Uses vasodilators to add stress to the heart in patients who cannot exercise for cardiac stress testing

24
