What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

In brief: Nuclear/ Echo stress

Lexiscan stress generally performed with nuclear isotope, which shows blood circulation(perfusion), comparing with medication lexiscan(stressing heart) and at rest.
Dobutamine echo we are looking at wallmotion of heart with medication dobutamine( stressing heart )and at rest to see they show any differences to detect blockages

In brief: Lexiscan/Dobutamine

Lexiscan is a pharmacologic nuclear stress test.
Nuclear stress will show heart wall motion but the images are not taken immediately after stress. Therefore, stress-induced wall motion abnormalities may not be seen. With Dobutamine stress echo, wall motion is measured immediately after stress. Therefore stress-induced wall motion abnormalities can be seen better.

In brief: Lexiscan

The lexi study uses radioisotopes for imaging, the echo study uses ultrasound and no radioactive exposure.
Lexiscan agent is not a heart stimulant, Dobutamine is. The images obtained are different also.
