CCRP Exercise Testing 2

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

Acute myocardial infarction within the past 2 days is an absolute contraindication to exercise stress testing per ACC/AHA guidelines due to risk of hemodynamic instability and infarct extension.

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

A drop in systolic BP of 10 mmHg or more from baseline with increasing workload (exertional hypotension) is an absolute indication for test termination, suggesting severe LV dysfunction or hemodynamic compromise.

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

A peak VO2 below 10 mL/kg/min indicates severely impaired functional capacity and is one criterion used in heart failure advanced therapy and transplant listing decisions.

Question 4

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

Accepted Answer

The exercise intensity at which lactate production exceeds clearance, causing a nonlinear rise in ventilation relative to VO2

Answer

The ventilatory threshold is identified by a nonlinear increase in VE relative to VO2 (V-slope method), reflecting the point where lactate production exceeds buffering and clearance capacity.

Question 5

Chronotropic incompetence is defined as failure to achieve what percentage of the age-predicted maximum heart rate during maximal exercise testing?

Accepted Answer

80%

Answer

Chronotropic incompetence is defined as the inability to achieve 80% or more of the age-predicted maximum heart rate during maximal exercise, indicating impaired sympathetic heart rate augmentation.
