Eco de esforço em esteira com imagens do pico do exercício.

Comparison of Peak and Postexercise Treadmill Echocardiography with the Use of
Continuous Harmonic Imaging Acquisition
(J Am Soc Echocardiogr 2004;17:1044-9.)
.
All EE was performed and analyzed by an expert
physician echocardiographer (6000 EE) blind to clinical
history, electrocardiography, and coronary angiography.
Rest and post-EE, and rest compared with peak EE, were
analyzed for every patient from optic disk–stored images
on separate days.
.
Sensitivity for CAD was higher with peak imaging (92% vs 77%, P < .001)
.
Na tabela acima, da diretriz de ecostress americana, 7 estudos com eco de esforço em esteira e imagens pós esforço, tem sensibilidade superior a encontrada no estudo acima, sendo apenas 3 estudos concordantes.

PALAVRAS DO AUTOR:
Imaging during peak exercise may require a greater degree of expertise than postexercise imaging and may limit the application of the technique.
