Your results are actually quite straightforward.
ischemia simply means lack of blood flow to a section of the heart and inferior refers to the lower section of the heart. A cath is required to see where the obstruction is and attempt to treat it before an MI occurs (heart attack). The blockage regarding the inferior part of the heart is usually quite a long way down one of the major arteries, either the LAD or the Circumflex.
Don't be discouraged if you don't get on right away, keep trying. Slots open up throughout the day based on time zones so you may get in later in the day as well.
Jon, thanks for your response. This is my first time on the forum, so I will now go to the experts forum.
Sorry, but if you're looking for an expert's opinion, you'll need to post on the experts forum, no doctors here.
Your EF is normal. Having said that, I would think that a report of a moderate size inferior ischemia along with EKG changes under stress would make me want a cath to be safe, just my opinion.
