Global longitudinal strain predicts long-term survival in patients with chronic ischemic cardiomyopathy.
Left ventricular (LV) global longitudinal strain (GLS) is a measure of the active shortening of the LV in the longitudinal direction, which can be assessed with speckle-tracking echocardiography. The aims of this evaluation were to validate the prognostic value of GLS as a new index of LV systolic function in a large cohort of patients with chronic ischemic cardiomyopathy and to determine the incremental value of GLS to predict long-term outcome over other strong and well-established prognostic factors. ⋯ The assessment of LV GLS with speckle-tracking echocardiography is significantly related to long-term outcome in patients with chronic ischemic cardiomyopathy.
