I am interested in talking with patients in stage 4 kidney disease to learn what treatments they are receiving. My husband is 75. He has high blood pressure which has been under control, but his heart rate was very low. 43. Cardiologist reduced one BP med and heart rate has improved, but diastolic BP is now high. He also sees a nephrologist. His gfr is low 20's. Nephrologist says his labs are stable and acts like he is ok. His diastolic BP has suddenly gone up to 100 at times. I am afraid he is near kidney failure, but nothing is being done. The cardiologist only took him off a medication that was known to lower heart rate and told us to go to the kidney doctor for help with the blood pressure. I think we need new doctors.
