| 目的：了解老年人脑血管的功能状态及TCD傅里叶分析在鉴别药物性头痛中的意义。方法：对42例老年冠心病患者(其中22例有明确的含服硝酸甘油后头痛史)含服硝酸甘油0.5mg前后进行TCD检查及傅里叶分析。结果：老年冠心病患者脑血流量低。服药后大脑中动脉(MCA)的平均峰流速(Vm)、空间平均流速(SMV)及血压、心率均无明显变化(P>0.05).头痛组MCA的相对横截面积(RC-SA)增大, 相对流量(RVF)增加。与无头痛组比P<0.001.结论：老年冠心病患者由于动脉硬化, 对硝酸甘油扩张脑血管作用不敏感, 而硝酸甘油致偏头痛时有局部的脑血管扩张, 脑血流量增加。TCD傅里叶分析可反映老年人脑血管的功能状态, 并可做为鉴别老年人药物性头痛的一种可靠的方法。 |

| Objective:To find out functional state of senile people’s brain blood vessel and significance of TCD Fourier analysis to judge drug headache. Methods:Examining 42 senile coronary heart disease patients before and after taking nitroglycerine (0.5mg) with TCD Fourier analysis.In this cases,22 had a definite headache history after taking drug.Result:Cerebral blood flow of senile coronary heart disease patients was lower.After taking drug,Mean peak flow velocity (Vm)、spatial mean velocity(SMV) in middle artery (MCA)、blood pressure and heart rates were not changed markedly (P>005).In drug headache group,relative cross sectional area(RCSA)、relative volume flow (RVF) in MCA were increased after taking drug(P<0001: versus that in non drug headache group).Conclusion:As a result of arteriosclerosis,Nitroglycerine did’t dilate brain blood vessel of senile coronary heart disease patients,But can dilate local brain blood vessel of drug headache patients,and increase cerebral blood flow of them.TCD Fourier analysis can reflect functional state of senile people’ brain blood vessel,and It is a reliable method of judging senile drug headache. |
