What diagnoses can come from a stress test?

Cardiac: I'm assuming you're referring to a cardiac stress test that is used to diagnose heart conditions and physical stamina.

Stress results...: Cardiac stress tests can provide a variety of details about the heart. Usually the most important finding is whether there is ischemia or not. Myocardial infarctions may also be seen. Left ventricular ejection fraction and lv volumes may also be assessed. Left ventricular wall motion and wall thickening can be seen. Right ventricular abnormalities can also be evaluated.
