Changes in cardiovascular structure and function in three groups. (A) Representative echocardiography images of the heart in the three groups. (B) The structure of the heart in the three groups. RV, right ventricle; RVD, right ventricle diameter; LV, left ventricle; LA, left atrium; IVS, thickness of the interventricular septum. The right ventricle diameter increased, and the thickness of the left and right ventricular wall increased, which showed that there was left ventricular and right ventricular hypertrophy in Group OSAHS, and there was no significant difference in the right ventricle diameter and the thickness of the ventricular wall between Group MAD and the control group. (C) Peak E: the peak of early diastolic velocities; Peak A: the peak of late diastolic velocities; a’: late diastolic mitral annulus velocities; E/a’ ratio: an estimate of left ventricular diastolic function; (D) e’: early diastolic mitral annulus velocities; E/e’ ratio: an estimate of LV end-diastolic pressures. (C,D) Showed that the diastolic function of the left ventricle degraded; however, there was no significant difference between Group MAD and the control group. (E) LV systolic performance was assessed by the left ventricular ejection fraction (LVEF). (E) showed that the diastolic function of the left ventricle decreased, which was not found in Group MAD and the control group.
