Key result
Study outlines methodology for longitudinal 2D strain during exercise stress echocardiography but reports no results.
Why the study?
Is global and regional 2D strain analysis feasible and contributory during exercise stress echocardiography compared to visual wall motion evaluation?
Observational (n=93)

Answers are grounded in this paper and cite their sources.
2D strain feasibility during exercise echocardiography untested here; leaves open any added value over visual wall motion assessment.
Methods Between February and March 2012, 93 consecutive patients (59 men, 54.9%), with mean age 58.8 ±11.8 years, underwent supine exercise stress echocardiography, in 150 kgm stages. Wall motion was visually evaluated using a semi-quantitative analysis at baseline, peak exercise and immediately after exercise. Longitudinal 2D deformation was analyzed in 16 segments at rest and immediately after exercise using a tracking algorithm of acoustic markers (AFI: automatic functional images, GE).

Caniggia et al. (2014) reported an observational. Supine exercise stress echocardiography was evaluated. The abstract describes the methodology for evaluating longitudinal 2D deformation during supine exercise stress echocardiography in 93 patients, but no results are reported.
