What test is most accurate to measure EF

Post by david1 » January 24th, 2008, 6:24 pm

Hi all,

on jan 1 i was in the hospital where i had an echo test done which showed my EF to be 28%.

Today i had nuclear stress test at my cardio office and the EF shows just 13%, what gives here. I asked cardio why so much difference, he was not able to give me a satisfactory answer, besides he told me that the dye and what ever chemical they injected for the purpose of nuclear stress test dilate ur heart and ur arteries, im wondering can that be the cause of the lower number. I feel quite well not any more short of breath than usual.

Please help.

God bless us all

There are several ways to measure EF. They are all subjective. I think the important thing is not the EF reading, but the trend. Is is going up, or down? The only way to know that is to have the same test administered every time. Different tests will always give different answers. Using the same test each time will give a good indication of where the EF is progressing.

My echo test shows an EF of 45%. A nuclear stress test shows 35%. I talked to my EP yesterday and he says that the difference in figures is not unusual and he feels that the stress test is more accurate.
