| 摘 要： | 目的：评价肥厚型心肌病（HCM）患者的左房射血力并探讨其意义。方法：使用超声技术测量56例HCM患者和33例正常对照的左房射血力，根据HCM患者左室舒张功能受损程度不同依次分为Ⅰ、Ⅱ、Ⅲ、Ⅳ组。结杲：左房射血力，Ⅱ、Ⅲ组高于正常对照组、Ⅰ组和Ⅳ组，其中Ⅱ组又高于Ⅲ组（P均〈0．05）；肺静脉口A波峰值流速，Ⅱ、Ⅲ、Ⅳ组明显高于正常对照组及Ⅰ组，其中Ⅱ组又高于Ⅳ组（P均〈0．05）；左房泵血量，Ⅱ、Ⅲ组高于正常对照组（P均〈0．05）。结论：多数肥厚型心肌病患者左房射血力代偿性增加，左房射血力受心室顺应性等因素影响。

| Abstract: | Objective:To evaluate the left atrial ejection force(LAEF)in patients with hypertrophic cardiomyopathy(HCM).Methods:The LAEF in fifty-six patients with HCM and thirty-three normal control subjects were estimated echocardiographically.Patients with HCM were divided into four groups(I,II,III,IV)according to the severity of left ventricular diastolic dysfunction.Results:The LAEF force in groups II,III were significantly higher than that in other groups while it was higher in group II than that in group III(all P<0.05).The peak velocity of atrial reveral flow in pulmonary vein were higher in groups II,III,IV than those in group I and normal controls,while it was higher in group II than that in group IV(all P<0.05).The left atrial ejecting volume in groups II,III were higher than that in controls(all P<0.05).Conclusion:The LAEF in most HCM patients,which is influenced by some factors such as left ventricular complicance,has compensatory enhancement. |
