Abstract:

Objective

To quantitatively evaluate the changes of subclinical left ventricular myocardial systolic dysfunction in premature ovarian insufficiency (POI) women with normal left ventricular ejection fraction (LVEF) using real-time three-dimensional speckle tracking imaging (RT3D-STI).

Methods

Fifty-four women with normal LVEF diagnosed as having POI were employed as a POI group, and 42 healthy women with matched age, height, and body mass were enrolled as a control group. Both groups underwent conventional transthoracic echocardiography to obtain conventional left ventricular geometric and functional parameters, while RT3D-STI was performed to obtain the three-dimensional left ventricular myocardial systolic function parameters: Global longitudinal strain (GLS), global circumferential strain (GCS), global area strain (GAS), global radial strain (GRS), and three-dimensional left ventricular ejection fraction (3D-LVEF). The differences of the above parameters between the two groups were compared.

Results

The end-diastolic interventricular septal thickness in the POI group was significantly larger than that in the control group (P<0.05). The values of E, E/A, and lateral e in the POI group were significantly lower than those in the control group (P<0.01 or P<0.05). The myocardial performance index in the POI group was significantly higher than that in the control group (P<0.01). There was no significant difference in two-dimensional left ventricular ejection fraction (2D-LVEF) between the two groups (P>0.05). The GLS, GCS, GAS, and GRS were significantly decreased in the POI group compared to the control group (P<0.01), but there was no significant difference in 3D-LVEF between the two groups (P>0.05).

Conclusion

The left ventricular myocardial systolic function might be impaired subclinically in POI women with normal LVEF. Compared with LVEF, three-dimensional strain parameters of RT3D-STI can be more sensitive to assess the subclinical changes of left ventricular myocardial systolic function for POI women, indicating that RT3D-STI could be used as a non-invasive method to evaluate the early impairment of left ventricular myocardial systolic function in POI women.
