【摘要】 目的探讨血清镁离子水平与心脑血管疾病的关系。方法采用络合指示剂比色法测定66例健康人和189例各种心脑血管病患者血清中的镁离子水平。结果正常健康组为0.95±0.15mmol／L，风湿性心脑病组0.72±0.16mmol／L，冠心病组0.76±0.19mmol／L，脑梗塞组0.8±0.14mmol／L，肺原性心脏病组0.84±0.18mmol／L，冠状动脉硬化组0.77±0.23mmol／L，高血压组0.88±0.19mmol／L，脑出血组为0.9±0.2mmol／L，心肌炎组为0.87±0.14mmol／L，与健康组比较，风湿性心脏病组、冠心病和脑梗塞均有非常显著性差异（P＜0.01），肺原性心脏病和冠状动脉硬化差异显著（P＜0.05），高血压、脑出血和心肌炎差异无显著性（P＞0.05）。结论大部分心脑血管疾病的心肌都有不同程度缺镁现象存在，测定患者血清镁离子水平能对各种心脑血管疾病有一定的诊断价值。更多还原

【Abstract】 To investigate the relation between serum magnesium ion (Mg2+ ) and cardiocerebrovascular diseases. Methods The level of serum Mg2+ in 66 healthy people and 189 patients with various kinds of cardiocerebrovascular disease were determinated by complex indicator colorimetry. Results The serum Mg2+ level of healthy pmple was 0. 96 ± 0. 05mmol/L , that of patients with rheumatic heart disease was 0. 72± 0. 16mmol/L , that with coronary disease 0. 76±0. 19mmol/L, that with cerebral infarctior 0. 8 ± 0.14mmol/L, that with cor pulmonale 0. 84± 0. 18mml/L, that with coronary atherosclerosis 0. 77±0.23mmol/L that with hypertension 0. 88 ± 0.19mmol/L, that with cerebral hemorrhage 0. 90±0. 2mml/L and that with myocarditis 0. 87 ±0 .14mmol/L respectively. There was very significant difference between healthy people and patients with rheumatic heart disease, coronary disease or cerebral infarction (P<0. 01 )significant difference between healthy peop1e and those with cor pulmonale or coroary atherosclerosis (P< 0. 05). No significant difference was shown between healthy People and patients with cerebral hemorrhage or myocarditis (P>0.05). Conclusions Various degrees of magnesium deficiency exist in the myocardium of a majority of patients with cardiocerebrovascular diseases. So, determination of patients’ serum Mg2+ level is of value to the diagnosis of such diseases.更多还原
