Brief Answer:
Coronary Artery Disease / need further assessment

Detailed Answer:
Hi friend
Welcome to Health Care Magic

This means the blood supply to a particular area (front middle portion of the heart) is normal at rest, but reduced during stress (exercise). The blood vessel can supply enough blood at rest, but is not able to allow increased supply during the increased need / In other words, a narrowing (block) in the blood vessel supplying the area … / in other word – Coronary Artery Disease… Here probably a single vessel ; probably LAD (Left Anterior Descending) artery
The next step is to see the ANATOMY (structure) – undergo catheterisation and coronary angiography with a view for possible intervention. It is the only way to directly ‘see’ the block, if any – and its location, extent, severity and so on. Coronary arteriography is invasive but it is the gold standard for this. [CT angio is non-invasive study for the anatomy. If positive, she will need catheterisation, anyway.]

Good luck
God bless you
