冠心病心气虚与非心气虚证间左心形态及功能表现

目的]比较胸痹(冠心病)心气虚与非心气虚患者左心形态及功能方面的差异。方法]回顾分析1998~1999年就诊的184例冠心病患者的临床资料,由中医师按病例记载的临床证候分为心气虚组和非心气虚组,再比较两组患者超声测量的数据特点。结果]心气虚组与非心气虚组的左室射血分数和心肌缺血程度仍在正常值范围,心气虚组的射血分数为(61.0±15.1)%,非心气虚组为(66.62±12.67)%,两组比较差异有显著性(t=2.754,P<0.01);心肌缺血程度两组间比较也有显著性差异(秩和检验Uc=53.99,P<0.0005)。超声测量左室腔和左心房大小、左室心肌厚度、左室每搏量、心输出量、心肌缺血范围,结果两组间差异无统计学意义。结论]心气虚并非等同于临床上的心功能不全,超声测量虽在正常范围内,但射血分数表现为正常低值者,对胸痹(冠心病)的病程进展的判断可能有所帮助。

Morphological Feature and Function of Left Ventricle in Coronary Heart Disease with and without Heart-Qi Deficiency Syndrome

ive] To compare the morphological feature and function of left ventricle in coronary heart disease (CHD) with and without heart-Qi deficiency syndrome. Methods] A retrospective analysis was carried out. One hundred and eighty-four cases of CHD adopted from 1998 to 1999 were differentiat ed as heart-Qi deficiency syndrome (Group A) or non-heart-Qi deficiency syndrome (Group B). Related ultrasonic parameters were measured. Results] The left ventricular ejection fraction (LVEF) and the de gree of myocardial ischemia were normal in the two groups. LVEF was (61.0 ?15.1)% and (66.62?12.67)% in Group A and Group B respectively (t =2.754, P<0.01). Myocardial ischemia was severer in Group A than that in Group B (Uc = 53.99, P < 0.000 5) . No significant differences of left ventricular end diastolic diameter, left atrium diameter, left ventricular wall thickness, stroke vol ume , cardiac output and myocardial ischemia area were found between Group A and Group B. Conclu sion] There is no specific relationship between heart-Qi deficiency syndrome and cardiac function.
