目的探讨运动与血钙离子的相关性,为临床诊治提供依据。方法选用两组健康人:年龄40~60岁,内科检查无器质性病变,分别为常规心电图正常组和ST-T异常改变组,应用标准Bruce方案进行次极量平板运动试验,同步监测血压和12导联心电图,记录运动前、运动中及恢复期的血压和心电图,并在运动前及运动后2 m in抽取血样,行血钙离子检验。把两组运动前后血钙离子变化例数进行χ2检验。结果正常组13例中,运动后10例血钙离子量增加,占正常组76.9%,ST-T异常改变组5例中,运动后4例钙离子量增加,占改变组80%;χ2=0.24,P>0.05,两组运动后钙离子增加率差异无统计学意义。结论运动可使血钙增加,并且后者的量增加与运动前ST-T改变与否无关,即与运动前心肌缺血与否无关。 Objective To explore the correlation between exercise and blood calcium, and to provide evidence for clinical diagnosis and treatment. Methods Two healthy subjects were selected, aged 40-60 years old. There was no organic disease in the medical examination. They were the normal ECG group and the abnormal ST-T group. The standard Bruce protocol was used for the submaximal treadmill exercise test. The blood pressure And 12-lead electrocardiogram were recorded before exercise, during exercise and recovery of blood pressure and ECG, and before exercise and after exercise 2 m in blood samples, blood calcium test. The two groups before and after exercise calcium changes in the number of χ2 test. Results Among the 13 cases of normal group, the amount of calcium increased in 10 cases after exercise, accounting for 76.9% of the normal group. In 5 cases of ST-T abnormal change group, the amount of calcium increased in 4 cases after exercise, accounting for 80% of the change group; χ2 = 0.24, P> 0.05. There was no significant difference in the increase rate of calcium after exercise between the two groups. Conclusion Exercise can increase blood calcium, and the increase of the latter is not related to the change of ST-T before exercise or not, that is to say, it has nothing to do with myocardial ischemia before exercise.
