Association between Resting Global Longitudinal Strain and Clinical Outcome of Patients Undergoing Stress Echocardiography.

Reduced GLS of the left ventricle is associated with adverse prognosis in healthy subjects and in different cardiovascular conditions. Rest GLS may enable risk assessment independently from stress-echocardiography (SE). We assessed whether there is an association of global longitudinal strain (GLS) measured at rest before SE with long-term outcome, independent of clinical parameters or inducible wall motion abnormalities (RWMA) and Doppler coronary flow velocity reserve (CFVR).
