I would recommend performing a stress cardiac MRI.
Detailed Answer:
Hello!
Welcome to Ask a Doctor service!
I understand your concern and would explain that in this case it is important performing a stress cardiac MRI, which would properly guide us on the necessity or not of a cardiac bypass.
You should know that this is an accurate test to help examine better the heart function and structure and also the myocardial viability ( tissue characterization). From the other hand this test can help investigate any potential cardiac ischaemia.
Only by performing this test, we would be able to come into a right conclusions and decide if bypass is necessary or not.
You should discuss with his doctor on the above test.
Hope you will find this answer helpful!

My answer as follows:
Detailed Answer:
Hello again!
A cardiac stress MRI is different form a cardiac stress test, as it is a type of cardiac MRI and the patient does not do any physical effort during the test.
It can help examine the myocardial tissue viability and its collateral blood flow.
According to the angiogram report, there is a 50% proximal LAD stenosis and a distal 100% occlusion. In such case, the myocardium supplied by a distal 100% occluded branch could theoretically have two alternatives:
1- the underlying cardiac muscle might have not survived due to interruption of blood supply; the myocites may have died and been replaced with scar tissue. In such case performing a revascularization in such area (bypass) would be worthless as it would serve to nothing (there is no contracting muscle any more)
2- the second option is that some small collateral vessels may have developed with time giving a suboptimal but vital blood supply, such way saving the myocites from death. The cardiac muscle may decrease its oxygen request on its own and helping such way to reduce further damage expansion. In these conditions performing revascularization (bypass) would be really helpful as it would restore the blood supply and return the normal muscle metabolism.
Coming to this point, the cardiac MRI would help to differentiate between these two conditions, and conclude whether he should undergo bypass or not.

I cannot thank you enough for such an honest and comprehensive answer! Thank you so much. We are going to the cardiologist today and we are going to request an MRI. To be honest I’m surprised this is not a routine part of pre-surgery testing, but I suspect heart surgery rates would be greatly reduced if so....
So does the fact that the 100% blockage is in the distal not higher, make it any less of a ‘widow maker’? I guess just to be blunt, my question is : if XXXXXXX chooses not to do anything at his age, would he be in grave danger or is there also a likelihood of a good outcome given the fact he has low blood pressure, no diabetes no heart pain, 98-100% oxygen saturation all day, an excellent pulse, etc...
We feel like maybe he has had this blockage for a long time but I guess there is not a way to determine how long it has been blocked? Or maybe the MRI would give an indication?
Thank you so much I am really enjoying learning all these new things!! Truly, I believe I have gotten more solid information and reasonable advice from you, than from three doctors we have spoken to in person, here!!
I would explain as follows:

Hello again!
I understand your concern and would explain that as long as he does not have chest pain or shortness of breath during straining physical activity, it may indicate that he may do well with medication, even without surgery.
Anyway, the cardiac MRI is necessary because it can give more information if the 50% stenosis is causing myocardial ischemia during physical effort or not.
Regarding the time of blockage, the cardiac MRI can give a lot information if this blockage is recent or it has happened a long time ago.
Hope to have been helpful!

We are completely on board with the idea of an MRI, we feel like this will enable us to make a fully informed decision and we so greatly appreciate your advice! I’m not sure when I will know more because sometimes it takes several weeks to deal with insurance companies here in Texas! But as soon as I get another answer I will let you know.
Also the primary care physician suggested he double his statin dose from 20 mg to 40 mg daily. Oddly the cardiac doctor never did a lipid test, so the last one on file is from the primary care physician one year ago. It was normal at that point but the primary care doctor thinks it’s best to double the dose. He told him to start doubling the dose right away. Tomorrow my brother will be getting a lipid test and I assume we will have the results Monday or Tuesday. Historically his cholesterol has just been slightly higher than normal.
I will let you know as soon as I hear more and again thank you so much and I hope you and your family have a wonderful weekend!! you have been very much a blessing to us!
You are welcome!
Detailed Answer:
Hello again!
Of course the decision of increasing statins should be based also on the blood lipid profile results.
I would be glad to review his test reports as soon as you will be able to upload them for a second professional opinion!
Please let me know about everything!
Wishing all the best,
Dr.Iliri


Look forward to your opinion!
