Very slow recovery after CABG

My husband had a double bypass Oct. 10. He didn't have a heart attack and had no damage to his heart at all. He entered the hospital after experiencing shortness of breath with very little exertion. He is 53 and has always taken good care of himself, but heart problems are in his family.

Since surgery, he's had all kinds of problems. It started with low blood pressure (the docs had a hard time getting it high enough post-op) which caused problems with recovery since it caused him to get dizzy and almost black out every time he got up.

8 weeks later, he still has no energy. When he went for a stress test about 3 weeks ago, he had to stop after about 2 minutes. His heart rate/pulse/blood pressure remained normal, not rising at all. But, he was out of breath and couldn't keep up.

He's scheduled for an echo in January, with a follow-up in February, but his family doc suggested he may have leaky valves or nerve damage from the surgery.

I was wondering if anybody here has experienced the same symptoms or could shed some light??

Thanks

has he been checked for anemia?

how is it going now? my recovery from single bypass, off-pump, has been even more grueling and slow. I am 16 weeks from surgery and Ive only resumed a 2-hr a day work schedule. I need the evenings and weekends to rest up. I have constant low grade fevers in the afternoon, into the evening and then I have night sweats. The fevers and night sweats only subsided for 3 weeks while i was being treated with massive antibiotics for pneumonia. I have had my left lung drained twice (thoracentis).
I am getting the run around from my three docs, the PCP, the cardiologist, the lung surgeon. They are pre plexed at the fevers to the point that they are shrugging their shoulders.
Im 50yr female. I do have a major medical history of radiation of chest for Hodgkins. Still, with this info, I am not getting guesses, let alone answers.

Let me know your progress by now
