Prognosis is good: You might have a condition called microvascular dysfunction, meaning that the arteries that can only be seen under microscope are mot working properly. There are a few small studies saying that a medication called ranaxa helps. Also exercise should help out endothelial function. The good thing is that your prognosis is very good.
