Figure 5. The relationship between E and echocardiographic ventricular wall thickness in the younger and older cohorts.

Figure 5

A: In the mathematical model, the positive association between IVSd and E when the value of Inline graphic is low, moderate, and high. B: The positive correlation between Inline graphic and IVSd with different average values of E (Inline graphic for the 20–45, 45–60, and Inline graphic Inline graphic age groups, respectively). Because circumferential strain = 0, a (internal dimension), pressure, E = f (LVPWd), or E = f (IVSd) was fixed. IVSd = intraventricular septal width in diastole; LVPWd = left ventricular posterior wall width in diastole.
