I know that it is a n out-patient procedure. However, I cannot afford to overlook any other possible medical condition. I look forward to your reply.  <response>: Hi, Swelling in the foot in a patient with cardiomyopathy and low heart function is generally because of fluid overload which gets accumulated in the dependent part of the body. I can see that she has an abnormal and deranged kidney test creatinine. She might be having low urine output causing deranged kidney tests and swelling in the foot. You should increase the dose of Furosemide in her. She can 80 mg thrice a day is urine output is low. She also needs to restrict the total fluid intake to around 1 literday. Get her ICD battery replaced as planned as it is important for her to prevent sudden cardiac arrest. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
