Background Left ventricular (LV) pressure-strain loops (PSLs) have been recently validated as a non-invasive index of myocardial performance. Aim of the present study is to compare average cardiac work (avgCW), positive work (avgPW), negative work (avgNW) and work efficiency (WE) in normal subjects (NOR) and in cardiac resynchronization therapy candidates (CRT). Methods we included in this study 20 NOR and 61 CRT patients (mean LVEF, GLS and QRS duration: 64±5 vs 27±5%, -23±2 vs –8±3%, 71±21 vs 170±17xa0msec; respectively, all p Results with respect to NOR, CRT patients showed an increase in avgNW (329±139 vs 174±67mmHg%, p Conclusions regional LV-PSLs allow the assessment of global and regional myocardial performance. Their relationship with LV dyssynchrony provides a window for a best understanding of LV mechanics and it will help in defining the most specific parameter for predicting the non-response to CRT.
