This is my situation too. I have never had an issue with High BP. After the first I was doing great, and the doctors were ok with every thing I had done. The second one took everyone by surprise. The doctors explained it as being caused by an "unstable plaque".

Statin drugs had lowered my cholesterol somewhat. Even though I was watching the quantities of what I ate, the quality sometimes took a back seat. I still ate things like hot dogs and foods with moderate amounts of hydrogenated oils. I am convinced that people in our boat really need to avoid saturated animal fats and hydrogenated oils. Things I no longer eat are sausage of any kind, including McNuggets (yes, they are basically a chicken sausage), packaged cookies, even the girl scout kind. Hostess pies and Twinkies and stuff like that. Cool whip-real whipped cream is OK in very small amounts. Non-dairy coffee creamers. when eating out, most places will give you 2% for your coffee if you ask. I will use (sparingly) whole milk, or real cream if there is no 2%.

Since I started doing this after my second MI I feel better. I am sure a big part of this is mental, but my cholesterol numbers have improved so much as a result of these changes that my statin dose has been cut way back.
