Figure 3. Changes in left ventricular (LV) and right ventricular (RV) systolic and diastolic function occurred with age.

A, average LV ejection rate, normalized to BSA, significantly decreased with age (slope = −3.8 ml s⁻¹ m⁻² year⁻¹) but there were no significant differences between sexes. B, normalized average LV filling rate significantly decreased with age (slope = −3.8 ml s⁻¹ m⁻² year⁻¹) without a significant sex difference. C, average normalized RV ejection rate also was reduced with age (slope = −4.1 ml s⁻¹ m⁻² year⁻¹) and, D, there was an age‐related decrease in normalized average RV filling rate (slope = −4.1 ml s⁻¹ m⁻² year⁻¹) without a significant sex difference for either parameter. Linear regression (continuous line) was of data from male subjects (diamonds) and female subjects (squares).
