Core Tip

Core Tip: Left ventricular (LV) systolic function is impaired in type 2 diabetes mellitus (T2DM) patients, especially those with peripheral vascular disease (PVD). Layer-specific global longitudinal strain (GLS) and PSD can be used to detect LV systolic dysfunction flexibly, accurately and conveniently. The level of low-density lipoprotein cholesterol was positively correlated with global longitudinal strain of the epimyocardium, global longitudinal strain of the middle myocardium and PSD. PVD may aggravate the LV systolic dysfunction in T2DM patients. Layer-specific GLS and PSD can be used to detect LV systolic dysfunction flexibly, accurately and conveniently in T2DM patients with or without PVD.
