Question on Creatinine & eGFR

[kevintan12]

Hi, I was recently diagnosed for Coronary Artery Disease. Found 3 narrowing in my left and right ventricles of the heart. On 9th of March I did an Angiogram and this was found out. Before the Angiogram, they took my blood and found that my Creatinine levels were 87. They then put in on several meds. Aspirin 100mg (Blood Thinner), Astorvastatin 60mg (Cholesterol), Lisinopril 2.5mg (Blood Pressure), Ezetimibe 10mg (Cholesterol), Bisoprolol 1.25mg (Blood Pressure) and Frusemide 40mg (Edema).

Fast forward 1 week to 15 March, I took another blood test to prepare for a stent op and they found that my Creatinine went up to 127 with eGFR at 53. Doctor said that it could be dehydration as I did not take take too much water due to the edema. Maybe less than 1 liter per day. So I hydrated and the next day took another blood test. Results were 126 with eGFR 58. My doc asked for another blood test 2 days later. Results were 115 with eGFR 59.

My question, is this a good sign? When should I take another test? With borderline eGFR, is it safe to do a stent op? Especially using the dye? Are the meds causing my Creatinine levels to go up? After hydrating for 3 days and Creatinine drops to 115 from 127. Is this normal or should it drop more?

Any feedback will be helpful. Thanks again in advance.

Hi kevintan12,

eGFR of 59 will be OK, I would say 59 is not border line.

Less than 1l of water is bad for you, and your kidneys, in your condition I would say 2l is more like it (check with your consultant), if the oedema (water retention) gets worse they can always increase the water pills

The dye, unless it has changed recently, is known to give kidneys a shock but this is far outweighed by the gains from the stents.

I had stents fitted in my heart when I was much further down the line of kidney failure, in the short term I lost about 5% kidney function but about half of that loss came back in about two weeks. However this will vary from person to person, and the cause of the loss of kidney function.

Your eGFR would have to fall to around 20% or so before you would notice.

So I would say stop worrying , and get the stents in these will help to make some changes for the better.

Best wishes.

Thank you so much for the feedback. Really is a relief to know this. Today is my Stent procedure. Hoping for the best.

Good luck, or I suppose by now it should be, I hope all went well.

Hi, the stent op went well. I had 3 stent placed. Just wondering, after the op, did you feel any pain? I've got this soreness in my chest, however, it has since gone away. The only thing I feel now is that I tend to get out of breath more often than before the op. Before the op, I could walk for long distances without panting (no symptoms. the only issue was the Edema). Now, I sometimes can be out of breath after a short walk.

Did you get to see what was happening on the screens?

I expect they will have a rehabilitation program for you in a while.

I was told to rest for four weeks avoiding anything strenuous, defined as anything that made me breath hard.

I was told that they wanted the stents to get established, and let the heart sort itself out a bit.

The rehab (if they do it in your area) was very good, exercise, in a group, under supervision along with talks about the heart, diet, and exercise. I could see the new patients were protective of their hearts at first but after a couple of sessions they were much more into it all.

The group thing works well, at least you know you are not the only one.

Best wishes.

Thanks so much again for the feedback. Really appreciate it.

Yes there is a program. Will be seeing the consultant next Tuesday.

Incidentally, can I ask. We're you a scorer before the Stent? Somehow, after, I just stopped snoring. Not sure if that is a good sign or not. I was diagnosed with sleep apnea as well.

Did a blood test yesterday after my first consult with my Cardiologist after the stenting and all my levels were in the reference range, but on the high side. I'm not too concern as I'm hopeful they will improve. Creatinine is 110 and eGFR is >60. Even Potassium levels has gone back to normal. First time my blood test has no red marks LOL.

An almost fully functioning heart will make changes to many things, some you will notice, and some are less noticeable.

Thanks for the update Kevin, sounds like it worked out good wit hthe Creatinine.
