Depends on if it is taken for Angina/Chest Pains or CHF....
Trans RX Guide for FE - Ages 45-85
Angina - Based on date of diagnosis: Within 1 yr-Graded; Within 2 yrs- Standard; Over 2 years- Preferred
CHF - Taken within 1 yr- Graded; Within 2 yrs-Standard; Over 2 yrs- Preferred if CHF resolved
My experience with them is if there is any other issue, then you will get Standard as a minimum to Graded.
I am curious how one resolves congestive heart failure, outside of a transplant of course?
