What is the sestamibi treadmill stress test?

Nuclear study. This is a nuclear medicine test that tells your physician about your heart function. A small amount of nuclear tracer is given right after/during running on a treadmill followed by a scan. This is compared to a similar scan performed at a separate time under resting conditions. Any decreased area of tracer uptake in the heart during stress compared to rest indicates a possible artery block.
Nuclear Cardiology. I believe you are referring to a cardiac nuclear stress test. This test involves two scans of the heart - at rest and 'stressed' - using the radioactive isotope technitium sestambi 99, aka Cardiolite or myoview. Contrast is used for both scans. The treadmill portion is the stress is also known as an exercise stress test. The patient will walk until achieving and maintaining a target heart rate.

Is it possible for someone with vulnerable (soft) plaques to have a negative treadmill stress test, but still be in danger?

Yes. It's entirely possible - this is, in fact,the explanation for how someone can have a normal stress test and then have a heart attack hours, days, or weeks later: presumably there is no serious blockage at the moment of the stress test, but they rupture a plaque and occlude the vessel at a later time. This is a sad reality. We have no "crystal balls" to predict the future. Read more...
