You have mildly positive TMT few weeks ago and now you are having shortness of breath
along with sweating.I think you should take it very seriously as this can be because of Ischemic heart disease
with resultant blockage of coronary arteries.
I would recommend you to get your complete cardiac risk assessed with Echocardiography/Lipid profile/ fasting blood sugar.
You may need to go for coronary angiography
to visualize the heart vessels and possible intervention.
and certainly do not stop aspirin( ecosprin
av) before you get a clear picture.
