ABSTRACT
Objective To evaluate left ventricular myocardial systolic function in patients with obstructive sleep apnea hypopnea syndrome ( OSA HS) with normal left ventricular ejection fraction( LVEF) using three‐dimensional strain echocardiography . Methods One hundred patients with OSA HS were divided into mild group ,moderate group and severe group according to apnea hypopnea index ( A HI) w hile matched with 32 healthy people as control group . T he parameters such as three‐dimensional LVEF ,global longitudinal strain( GLS) ,global circumferential strain( GCS) ,global area strain( GAS) ,global radial strain ( GRS) ,twist and torsion based on standard three‐dimensional echocardiography were measured by three‐ dimensional strain echocardiography , the above parameters among the four groups were compared for difference .Linear correlationship between A HI ,LVEF and the three dimensional strain parameters was analyzed respectively . Results ①T here was no significant difference in three‐dimensional LVEF ,twist and torsion between each groups( P >0 .05 ) . ②GLS ,GAS and GRS were lower in mild ,moderate and severe group compared with control group ,decreasing along with the disease severity ( P <0 .01 or P < 0 .05 ) . GCS in severe group was lower than that in control group ( P <0 .01 ) . ③GLS and GAS in severe group were lower than those in mild group ( all P <0 .05) .GRS in moderate and severe group were lower than that in mild group( all P < 0 .05 ) ,GAS ,GRS in severe group was lower than those in moderate group ( P <0 .05) . ④T here was a mild correlation between GLS and A HI ( r =0 .342 , P <0 .01) ,GAS and A HI ( r=0 .294 , P <0 .01) ,GRS and A HI ( r = -0 .411 , P <0 .01 ) . T here was a mild correlation between GCS and three‐dimensional LVEF ( r= -0 .354 , P <0 .01 ) ,GAS and three‐dimensional LVEF ( r = -0 .326 , P <0 .01) ,GRS and three‐dimensional LVEF ( r =0 .300 , P <0 .01) . Conclusions T he left ventricular myocardial systolic function is impaired in all patients with OSA HS even with normal LVEF and the dysfunction is aggravating with the disease severity . Ultrasonic three‐dimensional strain imaging technology can be used to detect the subclinical myocardial systolic dysfunction quantitatively in the early stage of OSA HS patients .
