Uncle's diagnosed with chronic heart failure

[kyfarmboy]

I have been trying to search for some way to help my uncle. He is 56 years old, and has just had his 7th heart attack. He had bypass surgery about 10 years ago.
I was just wondering if there was any way to unblock an artery that is 100% blocked. He is only living on 2 arteries as of now, and is in constant pain.  Would his doctors be able to do another bypass on him, or is this it?

Thank you.

Ed provides a good assessment of the contingencies involved and the best treatment.

You state your uncle has chronic heart failure.  Very few surgeons will do a bypass when the EF is below 35% (the percent of blood pumped with each heartbeat), and if the heart is enlarged due to HF, it is difficult to preserve an acceptable functionality of the left ventricle.  A bypass would only be done if it is a matter of life or death.

There are only so many spare vessels which can be harvested from the body, so it depends how many have already been used in surgery. It also depends on the condition of the remaining available vessels. If they have disease, it's pointless using them.
There is an important factor you need to establish here before any decision can be made. Is any of his heart tissue now dead due to the 100% blockage? if so, how much? If the tissue is dead, there is no point in revascularizing the area because the tissue won't use the oxygen.
If the tissue is alive, it is likely he has developed natural bypasses called collaterals. Due to his constant pain, obviously they aren't sufficient. You could inquire about angioplasty, to see if they can re-open the vessel with a Stent. So, you really need to gather more information first. How well is his heart functioning? what is his EF% ?
