Abstract:
Objective To probe into the chnical value of strain rate imaging on the assessment of left atrial function in patients with hypertensive disorder comphcating pregnancy(HDCP).Methods Thirty two patients with HDCP and 20 control subjects were involved.Patients with HDCP were divided into 2 groups:17 with normal left ventricular mass index (LVMI) and 15 with left ventricular hypertrophy.These patients and controls underwent transthoracic echocardiography,strain and strain rate imaging examination.Atrial strain and strain rate imaging values of patients with HDCP were compared with those of controls.Multiple parameters were compared by one-way anova analysis.Results When compared with the controls,peak early diastolic strain rate (ESR) was significantly decreased in HDCP patients with normal LVMI and left ventricular hypertophy [(-1.13 ± 0.15),(-1.04 ± 0.29) s-1 vs.(-1.26 ± 0.23) s-1,P ＜ 0.05].Compared with the normal LVMI,peak late diastolic strain rate (ASR) was significantly decreased in controls and patients with left ventricular hypertrophy [(-1.23 ± 0.25) s-1 vs.(-1.36 ± 0.33),(-1.34 ± 0.32) s-1].There was no significant difference in the others (P ＞ 0.05).Conclusion Left atrial function is decreased in HDCP patients,which with left ventricular hypertrophy,the tendency is more obvious.
