Stress test accuracy
Hello,
One of my family members (late 70's in age but active and an exerciser) recently had a NORMAL nuclear stress test with no signs of ischemia. There was no chest pain, SOB or other symptoms. No fatigue during the test. Because of some benign palpitations, they also had a series of other testing....EKG's, blood work, echo, 2 24 hour Holter's -- all normal.
A couple weeks following the normal stress test, an E.R. visit for some chest pressure. Again, labs, EKG etc. were normal but because of symptoms and other discusssions a catheterization was performed, a very signficant blockage was found in the LAD and a stent was placed.
A stress test to follow up the stent weeks later was also NORMAL. Here's my question: If there are a very small percentage of false negatives, as I understand, with stress tests (and this was one case) is it appropriate to then follow-up the placement of a stent with a stress test? Would catheterization be in order here? It would seem to me that if the stress test was normal to begin with, it would be "normal" again even if there was a problem. Thank you.

I got no doctor read on my holter report! I paid for and he handed it to me. Opened the door and walked out. My GP and Cardio said, I wasn't need one. All in my head! Here is my holter report. If anyone knows, please comment!

I've a pacemaker. I'm a wpw and the people in the web said wpw with ST segment is normal! Stress Test said "The changes seen could be due to attenuation artefact, but ischaemia cannot be excluded." My cardio not a concern either!

I had severe bouts of angina for 7-8 years and not TWO Stress Thalliums nor a Dobutermine Echo nor a Nuclear Adenosine Cardiolite showed anything.....I had to have a heart attack before something finally showed up. )-: Now, I have scarring.

i don't have the actual test all it stated was "tracing revealed sinus rythem with an episode of tachycardia (up tp 117 mpb) with questionalble ST segment depression. Impression: possible myocardinal ischemas" doc ordered another stress test since my last two within the last 2 years all have came back clear. had stress test 2 days ago, doc didn't seem overly concerned, asked me if i ever has clots in leg or lungs.answer was no. stated that there was something wrong with my right atrium however my heart did fine during the stress test. he further stated he believes pulmonary problems need to be ruled out as well.so right now i am just waiting to see him next thursday for the results. don't know what else to do. i don't know if this was any help to you what did your summary of the report state? take care
I don't know am I passed or not? My duration is 1.5 mins and terminated by the Dr there.
I'm interesting and wish to compare my holter with you. Is that Ok? Which numbers or sections showed possible ischemia? Do you have a report in your hand?
Take care.

I myself am a little confused about stress tests, 2 years ago I was diagnosed with mild left mitro regurtitation. Have had EKG's, stress tests, echo's and passed except the prolapsse. My chest pain continued, wore a halter it found possible ischemia. Had a 2 day stress test with the dye and DR said ......something is wrong wrong with your right atrium.....stress test just happened yesterday don't have another appointment until next week to find out results. But now I am a little worried. I passed the stress test with 99% in over 7 min. I have been trying to find out more about the right atrium does anyone have any websites that could explain more in detail about the right atrium? Thanks in advance.
If Stress Test is so inaccurate, why they want our heart in that torture place for? It costs AUD$958.30 which is very expensive!
