My nuclear stress test results were as follows ver batim. I do not know what it means, are the results acceptable, good very good etc. What does this say about the blood flow to the heart muscle ?
"injection of Myoview nuclear tracer & resting images obtained excercised on a treadmill for 5 min 34 sec. to 10.1 Met workload achieving 95% age predicted max heart rate with a double product of 21600 injected with Muoview @ 85% age predicted max heart rate and excercise cont for 1 minute beyond that teat limited by fatique and short of breath."

No ST segment changes indicates there is no induced ischemia (lack of blood flow) to heart muscles with exertion.  10 METs is good...for a reference a well conditioned athlete can sustain 15 METs or better.  It requires 5 METs to meet ordinary living conditions without chest pain and shortness of breath.  That is the Bruce protocol.

With Bruce Protocol speed and elevation changes are made at 3 minute intervals. Obviously you didn't have that procedure to measure condition as 5 min 34 sec would definately not get to 10.1 METs.

You may have had the Balke 15 minute test run...start at 3.3 mph with an even elevation, then after 1 minute raise the elevation 2%, and every minute thereafter raise 1%.  I can tell you I'm not able to reach 10.1 without fatigue and chest pain.  I am able to do 7 METs for a half hour without a problem...sometimes I need nitro.
