Key result
Global longitudinal strain by 2D speckle tracking echocardiography showed better discriminative power for detecting critical LAD stenosis than conventional visual assessment (AUC 0.85 vs 0.73, P<0.05).

Strain analysis may detect subclinical LV dysfunction in critical LAD stenosis more often than routine echo parameters; leaves open whether it alters management.

Does myocardial strain analysis by 2D STE improve the detection of critical LAD stenosis compared to conventional visual assessment in patients with suspected CAD and no prior MI?
p-value: p=< 0.05
Global longitudinal strain by 2D speckle tracking echocardiography provides superior diagnostic accuracy over conventional visual wall motion assessment for detecting critical LAD stenosis in patients without prior MI.
Stanković et al. (2014) conducted an observational in Suspected coronary artery disease without history of myocardial infarction (n=269). Global longitudinal strain by 2D speckle tracking echocardiography vs. Conventional visual assessment of LV asynergy was evaluated on Detection of critical LAD stenosis (p=< 0.05). Global longitudinal strain by 2D speckle tracking echocardiography showed better discriminative power for detecting critical LAD stenosis than conventional visual assessment (AUC 0.85 vs 0.73, P<0.05).
