Should I do bypass if my stress EKG is OK?

My angiogram indicates I have severe blockage but stress EKG test and SPECT (Myocardial Perfusion Scintigrahpy) indicate I have sufficient blood to the affect area. Should I do the trip bypass now?

My Coronary angiography indicates:
- my left arteries have Severe ostial disease
- Large Ramus Intermedius branch with severe disease at mid part
- mid part of RPD branch (of RCA) has focal non-obstruction.

My SPECT (Myocardial Perfusion Scintigrahpy)  and stress EKG test result looks OK. Doctor said my Collateral has been built up to provide backup blood to affect area.

If you have no symptoms then you don't need any intervention. However, if symptoms do start to appear, you will need to have your RCA treated.

Where are the collaterals being fed from? this is what you need to establish. If they are being fed by another vessel becoming blocked, then they are at risk. You don't give the info as to where they are being fed from.
