Dear friend, welcome to HCM !
a positive TMT indicates that there is a blood supply problem to the heart , mostly due to a block in an artery to the heart.
it can not localise the block/ its degree.
you need an angiography
for that ... diabetes
is a risk factor for coronary disease. if creatinine
is Ok , that can be done.
stress thalium is again a stress test
your cardiologist is the best judge...
pl. get evaluated and keep me posted on the progress.
I hope I have satisfied your query. !
