Abstract

En 中文

Left ventricular global longitudinal strain (LV-GLS) is associated with increased risk of adverse outcomes in nonischemic dilated cardiomyopathy (NIDCM). However, it can be altered by LV afterload. The global myocardial work index (GMWI) accounts for LV afterload and could improve risk discrimination when compared with LV-GLS. We sought to determine whether GMWI outperformed LV-GLS for risk stratification in patients with NIDCM.
