Evaluate for CAD with coronary CT angiography in a patient with COPD

Question 1

Baseline electrocardiogram (ECG) abnormalities that limit the ability to interpret exercise ECG findings are an indication for?

Answer 1

stress testing with adjunctive imaging or anatomic assessment of coronary arteries.

Question 2

A noninvasive anatomic imaging study to evaluate for obstructive CAD?

Answer 2

Coronary CTA

Question 3

Function of Vasodilators, such as regadenoson or adenosine?

Answer 3

produce hyperemia and a flow disparity between myocardium supplied by unobstructed vessels and myocardium supplied by the stenotic vessel (in which the distal vasculature is already maximally dilated).

Question 4

In addition to identifying the presence of disease, perfusion imaging can?

Answer 4

Define the location and extent of reduced perfusion and provide additional prognostic information.

Question 5

Single-photon emission CT with the vasodilator adenosine can be performed in patients with?

Answer 5

Underlying reactive airways disease but should be avoided in patients who are actively wheezing

Question 6

Benefits of the newer selective adenosine A2A receptor agonists?

Answer 6

associated with less bronchospasm; however, bronchospasm may still occur as a result of some activation of the A2B and A3 receptors.

Question 7

Coronary angiography is an invasive test that carries significant risks. It should be considered in

Answer 7

Patients who have a high pretest probability for obstructive CAD

Question 8

Patients who have a high pretest probability for obstructive CAD

Answer 8

symptomatic patients with abnormal findings on noninvasive testing for CAD or patients with an acute coronary syndrome
