目的探讨运动与血脂(甘油三酯)的相关性,为临床诊治提供依据。方法选用两组健康人(年龄20～60岁,内科检查无器质性病变者),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6min抽取血样,行甘油三酯检验。把两组运动前后甘油三酯变化例数进行χ2检验。结果正常组22例中,运动后18例甘油三酯量增加,占正常组85.7%,ST-T异常改变组6例中,运动后4例甘油三酯量增加,占改变组66.7%;χ2=0.008,P>0.05,两组运动后甘油三酯量增加率无显著性差别。结论短时间快速运动可使甘油三酯量增加,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 lipid (triglyceride), and to provide the basis for clinical diagnosis and treatment. Methods Two healthy individuals (age range, 20-60 years old, with no pathological changes in medical examination) were selected as normal ECG group and abnormal ST-T group. Standard Bruce protocol was used for submaximal treadmill exercise test. Blood pressure and 12-lead electrocardiogram were monitored. Blood pressure and electrocardiogram were recorded before exercise, during exercise and during convalescence. Blood samples were collected 6 min before exercise and after exercise. Triglyceride test was performed. The two groups before and after exercise triglyceride changes in the number of χ2 test. Results Among the 22 cases of normal group, 18 cases of triglyceride increased after exercise, accounting for 85.7% of normal group. In 6 cases of abnormal ST-T group, the amount of triglyceride increased in 4 cases after exercise, accounting for 66.7% of the change; χ2 = 0.008, P> 0.05, no significant difference between the two groups after exercise triglyceride increase rate. Conclusion Short-term rapid exercise can increase the amount of triglycerides, and the increase in the amount of the latter has nothing to do with the pre-exercise ST-T changes or not, that is, has nothing to do with the pre-exercise myocardial ischemia or not.
