Thing I wanted to mention here is that it wasn't just a treadmill test it was a nuclear test meaning they inject dye into your veins while you're running they take pictures of your heart pre-exercise and then post exercise so they get clear concise pictures of how your heart is performing under extreme pressure also it looks for any type of blood flow that might be slowed down to to blockage NST doesn't really show blockages but it'll show areas of concern so there are two types of stress tests there's just the treadmill without the dye and then there's the nuclear stress test with the dye that's the one I suggest people get in these type of situations because it does give you a clear picture of what you and your doctors are dealing with
