Clarification. He said “Of course you have plaque on your heart. You’re sixty years old.” Are there any obstructions in my circulatory system? Probably. Are there any significant ones that obstruct blood flow? No. That would have shown up on the stress test.
He thinks I need to lower my cholesterol to slow the accumulation of plaque, but otherwise, I’m a healthy guy. This is an explanation I like. I’m sticking with it.
