Hi Doc,

Tomorrow I am scheduled to have cardiac catheterization which still can be cancelled depends on my decision tonight.
To make things difficult is, I have kidney problem, my internist found that I have glumerulonephritis (foamy urine, EFGR - checked last week: 51%, ureum creatinin: 1.6 above standard 0.8-1.5).
I'm afraid after catheterization my kidney function will decrease rapidly but if not, I worry if there is attack while my kidney function has fallen to below 30%, catheterization is no longer a safe option.
The reason for catheterization is because for the last 1 month, I often experienced nausea, dizziness, pain in the left arm spread to my back, and have sensation of sharp pain in the upper left chest pain, usually after I eat fatty food. The symptoms also accompanied with gas, bloating.
I have several times go to emergency, EKG is normal, doctor said it was due to IBS. However I also have stress test, although generally normal, however on one occasion, my heart showed rapid jump, which raised concern to my MD, therefore we agree to do catheterization.
What is your say about my problem? is it due to heart problem or gas trapped?
My question is, what is my best option now? should I continue with cardiac catheterization to see whether there is a really a blockage or reassured myself that it was due to IBS?

Many many thank you Doc
