【摘要】：目的应用二维斑点追踪成像(2D-STI)技术对缺铁性贫血(IDA)患者左心房功能的变化进行评价。方法将选取的65例IDA患者按照血红蛋白(Hb)浓度分成两组:B组Hb90g/L、C组Hb 60~90g/L。另选30例健康人作为对照A组。对三组进行常规超声心动图检查,测量左心房收缩前左心房容积(LAVp)、左心房最小容积(LAVmin)、左心房最大容积(LAVmax),并计算左心房被动射血分数(LAPEF)和左心房主动射血分数(LAAEF)。应用2D-STI测量左房各壁心室收缩期应变率(SRs)、舒张早期应变率(SRe)、舒张晚期应变率(SRa),并计算平均应变率(mSRs、mSRe、mSRa)。结果与A组比较,B组患者各项指标无明显差异(P均0.05)。C组的LAAEF、mSRa明显高于A、B组(P0.05)。C组的LAPEF、mSRs、mSRe明显低于A、B组(P均0.05)。结论 2D-STI可以对IDA患者左心房功能进行评估。
[Abstract]:Objective to evaluate the changes of left atrial function in patients with iron deficiency anemia by 2 D-STI technique. Methods Sixty-five patients with IDA were divided into two groups according to hemoglobin concentration: group B, HB 90g / L, group C, HB 60g / L, group C, HB 60g / L. Another 30 healthy persons were selected as control group A. Three groups were examined by conventional echocardiography. The left atrial volume before contraction was measured with LAVpP, the left atrial minimum volume with LAVmin, the left atrial maximum volume with LAVmaxa, and the left atrial passive ejection fraction (LAPEF) and the left atrial active ejection fraction (LAAEF1) were calculated. 2D-STI was used to measure the systolic strain rate of left atrium, early diastolic strain rate and late diastolic strain rate. Results compared with group A, there was no significant difference in all indexes between group B and group A (P < 0.05). The level of LAAEFF mSRa in group C was significantly higher than that in group A (P 0.05) and that in group C (group C) was significantly lower than that in group A (P < 0.05). Conclusion 2D-STI can evaluate left atrial function in patients with IDA.
