摘要
目的 :探讨扩张型心肌病 (DCM)患者心肌能量 (E)、能量效率 (EE)与左室收缩功能的关系。方法 :应用超声心动图检测 6 5例DCM左室收缩功能 ,根据相应公式计算出E、EE ,并与 5 4例正常对照组进行比较 ,了解DCM的E、EE与左室收缩功能的相关性。结果 :与对照组比较 ,DCM组左室射血分数明显降低 (P <0 .0 5 ) ;EE、E与左室射分数血呈显著正相关 (P <0 .0 5 ) ,且随心功能 (NYHA)变化而改变。结论 :DCM患者EE。
Objective: To observe the relation of energy、energy efficiency and left ventricular systolic function in patients with dilated cardiomyopathy(DCM). Method: Using echocardiography technique, left ventricular systolic function was measured and the energy and energy efficiency were calculated by formulas in 54 normal controls and in patients with dilated cardiomyopathy. The correlation of energy、energy efficiency and left ventricular systolic function was investigated. Result: Compared with control, the left ventricular systolic function in patients with dilated cardiomyopathy was weaker (P<0.05). EE and E were not only positively correlated with left ventricular systolic function in DCM group (P<0.05), but also varied with the change of heart function. Conclusion: E and EE of DCM are related to left ventricular systolic function.
