Q repeated - answer is given below it.

You refer him for a stress test which is scheduled to be done in 5 days time. Which ONE of the following should you ask to be done?

1. Exercise stress test
2. Dipyridamole (Persantine) stress
3. Dobutamine stress test
4. Adenosine stress test
5. Epinephrine induced stress test

Answer to Q2: c

The best stress test in general is exercise stress testing but patients with intermittent claudication cannot exercise adequately. In such patients a chemical stress test needs to be performed. Dipyridamole stress is preferred over Dobutamine but in a case with obstructive lung disease Dipyridamole may produce bronchospasm whereas Dobutamine would not- therefore Dobutamine stress test would be the test of choice.
