What is the False Positive Rate for Nuclear Stress Tests?

I've been looking around for this info, but can't find anything current. As of 2007 it seems like the rate of false positives was about 20%, which seems a little high to me. Does anyone know if they have made some advancements in either the equipment or interpretation that yields a better rate nowadays?

I've got a angiogram scheduled due to an abnormality that showed on the image on the stress test, but not on the EKG. I'm 47, in decent shape and my cholesterol is not bad (total 164, but the lipoprofile is at 1249: just shy of high). I do have a family history, though, and PVC's. Some chest pain, too, but both the doctors and I think it is probably an unrelated stress symptom.

I'm just second guessing my decision to go ahead with the angiogram, and would like to know if anyone has current data on the accuracy of the stress test imaging.

Thanks.

Re: What is the False Positive Rate for Nuclear Stress Tests?

Going from memory I believe the accuracy of a nuclear stress test is around 87%.
An angiogram is the only 100% way of knowing if you have coronary artery disease - 50% of people who drop dead from CAD have no symptoms.

Have the angiogram done - it could save your life.

Re: What is the False Positive Rate for Nuclear Stress Tests?

Sagey - My cardio Dr. says that it is 90% accurate. All my tests were normal ( including BP and heart rate) and had a angiogram and come to find out I had 2 blackages one 98 and one 99%. I was in the 10% range that showed no signs even the pictures onf my heart. I am 49 with family history on cad. I am lucky the Dr. I was probably close to a heart attack. Had 2 stents put in 3weeks ago.
