Dr. Spry: 76 year old male with CKD stage 3. Creatinine 1.8, 37 GFR. I am suppose to get a angiogram to confirm heart issue after failed stress test. This test uses a dye that is a problem for CKD patients. Is my kidney function too low to have this test?

I cannot give medical advice without performing a complete history and physical examination.  It is true that contrast administered for a heart catheterization can cause kidney injury.  There are preventative treatments that can be used safely to decrease the risk of kidney injury.  I suggest you discuss these treatments and risks with your cardiologist and your primary care physician (PCP).
