Exercise Testing

Question 1

Which type of test is used to measure functional capacity and diagnose CAD?

Answer 1

maximal stress testing

Question 2

Which test is performed when pts are post-MI or CABG?

Answer 2

low-level exercise testing

Question 3

Fill in the blank: An exercise-induced ST-segment depression of ___ mm or greater on a _____ exercise test has been identified as the most valuable indicator of prognosis after MI

Answer 3

2.0mm, low-level

Question 4

You have a pt with unstable angina at rest, BP of 190/110, severe heart failure, and serious arrhythmias at rest. Would they be a candidate for exercise testing?

Answer 4

no, pt has all contraindications

Question 5

What are some good rules of thumbs when it comes to exercise testing?

Answer 5

diastolic BP should remain the same or decrease 10 during exercise
HR increases 10 beats per MET
systolic BP should increase around 10mmHG per MET of exercise
are all normal responses to exercise

Question 6

What are the most common protocols for exercise testing?

Answer 6

Bruce and Balke

Question 7

What is the prognostic value of maximal exercise testing?

Answer 7

greater sensitivity and specificity in males over 40 compared to females, females higher rate of false negatives, ischemia (ST-segment depression) during early stages is correlated with more severe disease

Question 8

What would you do to stress test a patient who is unable to perform an upright exercise on a treadmill or cycle?

Answer 8

pharmacologic stress testing, inject a pharmacological agent to induce physiological stress
