Partial occlusion of the coronary arteries will cause ischemia (lack of blood/oxygen) to the heart muscle. EKG is an unreliable source, but it is some evidence of ischemia that can't ignored especiially with symptoms of chest pain and/or shortness of breath.
Would require a stress test to verify any blockage, degree of blockage and location.
teacherstaff, have you heard much else on your situation?
I had the same thing happen to me yesterday, when I mentioned some mild chest pains that I thought was just indigestion; my doctor ordered an EKG, and she said that it seems as though I may have a blockage, probably because they also detected a drop in the oxygen level somewhere in my heart.
I hope you are ok, and would love to hear what is going on with you now!
