- Re: additional arteries growing above blockage, it is called “collateral flow” and it may yet happen. However, it is not as effective as a normal blood flow. Your doctor should have told you that a heart healthy lifestyle and medications may prevent your Coronary Artery Disease from worsening. It will NOT improve!
- For whatever reason, when treated for your heart attack, your stents failed, not unusual and occurring 10-15% within the first year, even then requiring medications to prevent this from happening. You probably should have a coronary bypass operation and may still need one.
Hope this helps,
