I know my cardiologist was going to order a coronary angiogram but on my initial bloodwork my egfr was at 58 and he didn’t want to possibly stress out my kidneys from the dye they use, if I had happen to have any actual kidney damage. So he opted for the regular stress test ekg. Which from the readings he stated he highly doubted I had any kind of blockages and didn’t think I needed to do extra testing. But I’m sure he wouldn't oppose it if I asked.I would have a cardiologist order you a CPET test along with a CT calcium score just to be safe at this stage.
While I believe cardio and lifestyle changes will help here I also would want to rule out any blockages or other items just as a precaution.
My Primary, who specializes in nephrology, ordered a follow up Cystatin C test a month later that came up healthy with an egfr of 114. So I received the all clear there, he wasn’t worried in the first place since he figured the extra mass would skew the original test. Though he is sending me in for a kidney sonogram just to cover all his bases.
