welcome to healthcaremagic.
your TMT shows you have good exercise capacity for your age (calculated to be ~59 years, from the data given above) and you were asymptomatic during the test. this itself portends that likelihood of a significant obstruction in your coronary arteries (blood vessels supplying heart) is low. however in view of ST depression
more than 1mm in during stress test
it has been given mildly positive. the possibilities could be
a. it is a false positive response especially if the shape of ST depression was upslopping and you are otherwise asymptomatic.
b. it may indicate silent ischemia
if you are a diabetic, had undue shortness of breath
during TMT and ST response was downslopping.
i advise you to consult your cardiologist for further clarifications. he may advise you to undergo stress-imaging study (stress ECHO) or may choose to stop work-up depending upon the scenario.
