Strain ao repouso não marca a isquemia.

Although GLS has been associated with improved diagnostic accuracy in patients with obstructive CAD, our study may suggest that in INOCA, GLS is (1) largely normal, (2) not correlated with inducible ischemia, and (3) not predictive of Stres Echo findings.

Conclusions

In this cohort of INOCA patients, resting GLS values were largely normal and did not associate with the presence, severity, or location of stress-induced ischemia. These findings may suggest the absence of subclinical myocardial dysfunction detectable by echocardiographic strain analysis at rest in INOCA

Algumas linhas de pesquisas com camadas miocárdicas ao Strain apontavam diferenças no subendocárdio ao repouso.

Mas não evoluiram para o uso ao repouso e predição de isquemia

O GLS puro e amplo não revelava isquemia de repouso em casos leves.
