Hi Bruce,
Since you say your MD is easy to offend, I would approach it from the angle of asking for his input on what you've learned. Tell him you're worried about your risk of having another stroke, so you've been doing some research and want to share what you've learned to get his input, so you can be sure you're doing everything you can to prevent future complications.
If communication with your physician is an issue, it's in your best interest to consider switching physicians.
All the best,
