Your heart function is normal.
It means that there is a small area of your heart in the inferior and lateral aspects (not the entire segments but a small portion of them) of the heart that is not getting enough blood flow probably form coronary obstruction (CAD). This is typically managed with medications, but a catheterization with balloon angioplasty +/- stenting could be considered especially if you are very symptomatic, or can't tolerate medications well.
