用美产SpectraspanⅢA型直流等离子体-中阶梯光栅直读光谱仪测定120例冠心病患者血清中11种微量元素,并以无心血管疾病及其他系统慢性疾病者作对照(1组)。冠心病人依其心脏情况又分为无心脏扩大组(2组,37例),心脏扩大者(3组,45例),心衰组(4组,37例)。均按1979年冠心病诊断标准确诊。
Eleven trace elements in the serum of 120 patients with coronary heart disease were measured with the Spectraspan III A Direct Current Plasma-Ladder Grating Direct Reading Spectrometer (Group 1) without cardiovascular diseases and other chronic diseases. Patients with coronary heart disease were divided into two groups according to their heart conditions: enlarged group (37 cases), enlarged heart (45 cases) and heart failure group (37 cases). According to the diagnosis of coronary heart disease in 1979 confirmed.
