What is the sensitivity of ekgs, echocardiograms, and cardiac mris for detecting previous heart attacks? would a normal echocardiogram signal good prognosis in the event of a previous heart attack?

Yes: A normal Echo usually means the valves and pumping action of your heart is normal. However you would need a stress test and nuclear scan of your heart to see if the circulation in your heart is normal, and to see if you have any evidence of a heart attack. Good luck!

Depends: Depends on if you have had a full or partial thickness MI. A heart attack which damages the full thickness of the heart muscle is reliably seen on an ekg. An echo will show wall motion abnormalities with either type.

Very good: Cardiac MRI is the best test for detecting a previous heart attack. An echocardiogram is probably next, followed closely by ECG. All of these tests should be pretty good at picking up a MAJOR previous heart attack. A normal echocardiogram after a heart attack is indeed an excellent prognostic marker.

MI: in general a poor function on echo is a worse prognosis sign then a normal function on echo
