该文以火焰原子吸收光度法检测了60名心功能不全患者和30名心功能正常者的血清及淋巴细胞内钙、镁的含量。结果发现，心功能不全患者血清钙、淋巴细胞内钙明显高于正常对照组；心功能不全组淋巴细胞内镁明显低于正常对照组；心衰Ⅲ级患者较心衰Ⅰ级者血清钙及淋巴细胞内钙明显增高；心衰Ⅲ级患者血清镁及淋巴细胞内镁较心衰Ⅰ组者降低更为明显；各种不同病因组引起的心衰，淋巴细胞内钙均高于正常对照组，而风心病组升高更为明显，各种不同病因组淋巴细胞内镁均低于对照组，而风心病组降低更为显著。该研究表明血清及淋巴细胞内钙、镁的含量变化与心功能不全的程度有一定关系。
The content of calcium and magnesium in serum and lymphocyte of 60 patients with cardiac insufficiency and 30 normal persons with normal heart function were detected by flame atomic absorption spectrometry. The results showed that patients with cardiac insufficiency serum calcium and lymphocyte calcium was significantly higher than the normal control group; cardiac dysfunction in lymphocytes within the magnesium group was significantly lower than the normal control group; heart failure patients with grade Ⅲ heart failure serum calcium and Lymphocyte calcium was significantly increased; serum magnesium levels in patients with grade Ⅲ heart failure and magnesium in the lymphocytes were significantly lower than those in the patients with heart failure Ⅰ; heart failure and lymphocyte calcium in various etiologies were significantly higher than those in the normal controls , While the patients with rheumatic heart disease were more obviously elevated. The levels of magnesium in lymphocytes in various etiology groups were lower than those in the control group, while those in rheumatic heart disease group were more significant. The study shows that serum and lymphocyte calcium, magnesium content changes and the degree of cardiac dysfunction have a certain relationship.
