目的 应用应变率显像技术探讨妊娠期高血压疾病(HDCP)对患者左心房功能的影响.方法 将32例HDCP患者根据左心室心肌质量指数(LVMI)分成两个亚组:LVMI正常组(17例)及左心室肥厚组(15例).同时选择20例健康志愿者作为对照组.所有研究对象均行常规超声心动图及应变率显像检查.记录左心房的应变、应变达峰时间、收缩期应变率峰值、舒张早期应变率峰值(ESR)、舒张晚期应变率峰值(ASR)、舒张晚期应变率峰值达峰时间,以及左心房舒张末期应变率峰值达峰时间心率校正值.多组间参数比较采用单因素方差分析.结果 LVMI正常组及左心室肥厚组的ESR均较对照组显著降低[(-1.13±0.15),(-1.04±0.29)s-1比(-1.26±0.23)s-1],差异有统计学意义(P＜0.05);左心室肥厚组的ASR较对照组和LVMI正常组显著降低[(-1.23±0.25)s-1比(-1.36±0.33),(-1.34±0.32)s-1],差异有统计学意义(P＜ 0.05);余各项指标各组间比较差异均无统计学意义(P＞ 0.05).结论 HDCP患者左心房的功能降低,当左心室出现肥厚时,其功能降低更为明显.应变率显像技术可以无创性评价HDCP患者的左心房功能.

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.
