Of course this is also my personal opinion, but I will not go for an angiography unless that you have symptoms.
What I will do is to go to the cardiologist and get a exhaustive blood test including: sCRP, Homocisteine, IL-6, Tumoral Factor, cholesterol etc. The first ones will give information on the level of inflammation in your arteries.
Of course, if you go for the angiography, try to do it in a place where they can do the ballooning, stent in the same intervention.
