Feasibility and Contribution of Global and Regional 2D Strain during Exercise Stress Echocardiography

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).
