Stress Echo explaination please.

I am a 52 yr old female, have MVP, smoke less than 1 pk of cigs a day (yes, I'm TRYING to quit), had a stress echo last week with these results, that I hope someone can explain to me.  I should add that I've had no symptoms of heart probs other that the MVP.
Had an echo-stress test -- results: Resting echo overall normal left ventricular size and systolic function with an ejection fraction of app. 55% with mild septal wall hypokinesia. After exercise, images were obtained in similar planes. These revealed septal and anterior wall hypokinesia which was mild in degree.
Conclusion:  1. Stress Echo was positive for ischemia in the distribution of the left anterior descending coronary artery.
2.  Exercise capacity was formal for age at 7 metabolic equivalents of task.  3.  The patient was asymptomatic throughout the test.
How serious is this? Or, is it?  My cardiologist made it seem serious and wanted almost immediate cath. done, but I'm getting a 2nd opinion

Your heart is performing well (EF 55%).

However the wall that separates the 2 ventricles and the front wall of the left one, they move less of what they should. This can be produced by an obstruction of your left coronary artery.
This is the reason of your dr. asking for the cath.

I think that you should decide what to do.. What your symptoms are?
