I was also one week away from surgery, had my pre-op EKG which showed atrial fibrillation.had to have another EKG and a Cardiolite stress test, long story short... One week later the cardiologist cleared me for surgery, just got the call today and my surgery is rescheduled to June 25. So I will start the liver reduction diet again the end of this week. Good luck with the pulmonologist hope your surgery can be scheduled soon.
