运动和静息心肌断层及心血池显像对临床前期糖尿病性心脏病的诊断

Diagnosis of preclinical diabetic cardiopathy by myocardial perfusion tomography and cardiac blood pool imaging under exercise and rest state

对２３例无临床心脏病的非胰岛素依赖性糖尿病（ＮＩＤＤＭ）患者，进行运动和静息心肌血流灌注断层显像及门控心血池显像，了解二者之间的相互关系，并讨论其机理。结果表明：糖尿病组心肌异常显像的发生率为８３％，门控心血池显像、舒张功能减退的发生率为６９．５６％，收缩功能减退的发生率为３４．８％。同时评估心肌血流灌注断层显像和心血池显像可将形态与功能结合起来，对增加临床前期糖尿病性心脏病诊断的灵敏度、估测该病的发展和预后具有重要的临床价值。

Twenty three patients with non-insulin dependent diabetes mellitus without clinical cardiopathy were undertaken myocardial perfusion tomography and cardiac blood pool imaging under the condition of exercise and rest state.The correlation between the two examinations was studied.The result showed that in diabetic,the incidence of abnormal myocardium imaging was 83%. In cardica blood pool imaging, the incidence of reduced diastolic function was 69.5%and reduced systolic function was 34.8%. Simultaneous assessment of the two methods by combining morphyology with function could increase the sensitivity of diagnosis of preclinical diabetic cardiopathy and evaluate its development and prognosis. The results showed these two methods have important clinical value.
