I am 80 years old in excellent health. After not being able to get a blood pressure reading on either of my arms, my doctor put me through a series of tests and it was discovered I had a blockage in my artery, causing a weak left arm, tingling, and occasional chest pain. I was prepared for an angiogram, (balloon and stent), but the Radiologist told me I was very high risk, so I did not have him do it. Now I am considering a bypass. What is your opinion?
