How are cardiac ischemia and shortness of breath related?

I have had significant shortness of breath and am being treated with inhalers, nebulizer and meds. EKG and chemical stress test results said "provocable ischemia of interior (anterior?) wall ". Haven't gotten results of echocardiogram yet. I had it done 3 weeks ago, shouldn't I have heard something from my PCP by now whether it be good or bad? I am scheduled to see a cardiologist next week. Am I to ume that cardiologist will read echo before I am to see him and that is the way I will get the results?
