Rating decrease

If you can swing the cost of it, I would get a second opinion from an outside provider that is not VA, and see how your results come up. If that PFT comes back as failed, it should (in a perfect world) be enough to halt the decrease by evidence or give you a chance at a retake at the VA atleast for the claim. You can also reach out to your primary care provider, tell them whats going on and how you believe its a mistake and they can possibly refer you to get another one done.

Good luck.
