Overall Long Axis Strain Detection of Left Ventricular Systolic Dysfunction in Patients with Normal Ejection Fraction of Severe Aortic Regurgitation
摘要
Abstract
Objective:To investigate the two-dimensional speckle tracking detection overall long axis strain of left ventricular systolic dysfunction in patients with normal ejection fraction of severe aortic regurgitation (AR).Method:From June 2013 to December 2015,140 cases of normal ejection fraction of severe AR (including 67 cases of symptoms,accounted for 47.86%) in our hospital were selected as the AR group,another 49 healthy people were selected as the control group.The left ventricular global longitudinal strain(GLS),global circumferential strain(GCS) and global radial strain(GRS) were measured by two dimensional speckle tracking echocardiography.Result:The GLC in AR group was lower than control group,the difference was statistically significant(P<0.01).There were no significant differences in two groups of GCS,GRS and LVEF(P>0.05).The symptomatic AR were lower than those without symptoms AR,the difference was statistically significant(P<0.01). Conclusion:Left ventricular GLS decrease in patients with normal ejection fraction of chronic severe AR,and the symptomatic AR were lower than those without symptoms AR.GLS can detect occult myocardial dysfunction,may help to optimize the timing of aortic valve surgery.关键词
