Figure 1

Bullseye plots of time to peak longitudinal strain are shown in two T2DM patients using EchoPAC workstation 2DSTE analysis. The endocardium of the LV was tracked point by point in the apical four-chamber, apical three-chamber and apical two-chamber views. After 17 segments of the LV were successfully tracked, GLS and LV PSD were automatically abtained. A patient with controlled blood glucose (HbA1c < 7%) displayed an LV GLS of 20.4% (absolute value) and LV PSD of 37 ms (A). More pronounced LV GLS of 12.3% (absolute value) and LV PSD of 72 ms were observed in a DM patient with uncontrolled blood glucose (HbA1c ≥ 7%) (B).
