A stress test is not 100% accurate.
Coronary calcium score, stress test are all a good tool to start with but the only way to for sure k ow is a heart cath.
I known 2 people that passed the test, one died the next day from a heart attack. The other had quadruple bypass surgery a few weeks later.
I flunked mine and had 95-98% blockage in widow maker.
Hellifiknow except keep going to the docs and hope it all works out.
