CARDIOLOGY

Understand the best method of stress testing in patients with obstructive lung disease and intermittent claudication.

Explanation:

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 in a patient like this.
