Recently, myocardial work analysis as an echocardiographic tool to non-invasively determine LV work was introduced and validated against invasive measurements. Predicated on systolic hypertension and speckle-tracking derived longitudinal strain (GLS) during systole and isovolumic relaxation, it is considered less load-dependent than LV ejection fraction (LVEF) or GLS also to integrate informative data on LV active systolic and diastolic work. The Characteristics and Course of Hea
