摘要: Objectives: This study sought to examine the ability of left ventricular (LV) global longitudinal strain (GLS) to assess disease severity in patients with chronic systolic heart failure (HF). Background: Left ventricular GLS is a sensitive measure of LV mechanics. Its relationship with standard clinical markers and long-term adverse events in chronic systolic HF is not well established. Methods: In 194 chronic systolic HF patients, we performed comprehensive echocardiography with assessment of GLS by velocity vector imaging averaged from apical …
