My dad has been in the hospital since Thursday because he was having some chest pains, we later found out from the MRI that he had a "silent" heart attack in the past, which is basically he had a heart attack but didn't even know it. He has some damage to his heart and they found that one of his veins has collapsed. They transferred him this morning to a hospital where cardiology is a specialty to do an angiography to see what is going on a bit more clear, and then they were going to move ahead and do an angioplasty to open up the block veins in his heart.
I will keep you updated as soon as we learn some more information.
I appreciate your prayers and support.
