Question 1

Which of the following is an absolute contraindication to exercise stress testing?

Accepted Answer

Acute myocardial infarction within the past 2 days

Answer

Stable angina with recent medication adjustment

Answer

Controlled hypertension with resting BP 150/90 mmHg

Answer

Well-compensated chronic heart failure

Question 2

What systolic blood pressure response during exercise testing indicates an absolute need to terminate the test?

Accepted Answer

Drop of 10 mmHg or more from baseline despite increasing workload

Answer

Rise to 180 mmHg in a symptomatic patient

Answer

Rise to 200 mmHg without associated symptoms

Answer

Failure to exceed 130 mmHg at peak exercise

Question 3

In heart failure, a peak VO2 below what threshold indicates severely impaired functional capacity and may prompt transplant evaluation?

Accepted Answer

10 mL/kg/min

Answer

20 mL/kg/min

Answer

15 mL/kg/min

Answer

25 mL/kg/min

Question 4

The ventilatory (anaerobic) threshold during CPET is best defined as which of the following?

Accepted Answer
