老年人不同年龄段血流变与甘油三酯改变的影响

A study of the changes of blood rheology affected by serum triglyceride levels in different ages of the elderly

目的探讨老年人不同年龄段甘油三酯的改变对其血流变的影响。方法收集895例佛山地区60以上老年人体检资料,首先分为男女对照组(男747人,女148人),并以年龄段分为3个组别,以61～70岁为对照组,与71～80岁、80岁以上组别进行对比,通过统计分析,研究甘油三酯(TG)与全血黏度高切(WBACH)、全血黏度低切(WBACL)、全血还原黏度高切(WBOACH)、全血黏度低切(WBOACL)、血浆黏度(BPAC)等密切的关系。结果男性甘油三酯(TG)在对照组达到高峰,女性则以71～80岁组别达到高峰,随后稍有下降,但各组别仍然高于正常。而老年人血流变指标则以对照组为最高,随后也稍有下降,但各组别仍然高于正常,与甘油三酯(TG)呈正相关。结论老年人甘油三酯的升降造成血液的黏稠度的变化,从而引起血流变各项指标的改变,对预防老年人由于高血脂所引起的心脑血管等疾病有十分重要的作用。

Objective To evaluate the correlation between serum triglyceride（TG） level and the changes of blood rheology in different ages of the elderly. Methods 895 old people were divided into male and female groups with 3 age groups, including the groups of 61 to 70（for controls）, 71 to 80 and over 80 years old. TG and relevant indicators of blood theology were compared by statistical analysis. Results TG levels demonstrated the peaks in male with 61 to 70 years old and in female with 71 to 80 years of age. All of the groups showed high TG levels. The relevant indicators of blood rheology was highest in the controls compared with other groups, and all of the groups showed high changes. The changes of blood rheologic indexes and TG showed positively correlated. Conclusions Different triglyceride levels may affect the changes in blood viscosity, and thereby changing blood theology indicators.
