Re: microvascular diease(syndrome X)
Just curiosity, do you know what was the test that they did to diagnose the micro vascular disease?
You said that you had angina after running, are you sure that you are not over doing it? Every body will get angina beyond a certain limit... the point is was is your HR when you get the angina and what your age is? I am sure you know the formula Max HR = 220-age, If you are training hard, I thing you can reach the 95% of that... Beyond it, you can expect the angina.
Assuming that you have the micro vascular disease, have you tried the new anti angina drugs that work reducing the cardiac metabolism instead of dilating the arteries, I think they should not drop the BP?.
Also there are laser interventions to solve the problem by making small perforations in your myocardium, so blood can reach it directly from the ventricles, without need of the vascular system.
