Figure 2.

Comparison of the left ventricular (LV) systolic and diastolic indexes among the three groups. The systolic index was significantly lower in the restrictive group than in the other three groups, and significantly lower in the pseudonormal group than in the normal diastolic function group and the impaired relaxation group (*p < 0.05; **p < 0.01; ***p < 0.001). Whereas, the diastolic index was significantly higher in the normal diastolic function group compared to the three groups of diastolic dysfunction, and showed a significant reduction with the worsening of diastolic dysfunction (†p < 0.05; ††p < 0.001).
