脑白质高密度影(white matter hyperintensities,WMH)与高血压相关。研究人员对血压、颈内动脉血流速度参数和WMH的交互作用进行评估,分别获取694名社区居民在(69.6±0.8)和(72.6±0.7)岁时的血压资料,和(73.0±1.0)岁时的脑部MRI与颈内动脉超声资料。73岁时与70岁时相比,舒张压和平均血压降低,脉压增加,但收缩压差异无统计学意义。校正血管疾病和危险因素后,多元线性回归分析结果表明,73岁时的WMH与高血压病史(β=0.13,P<
White matter hyperintensities (WMH) are associated with hypertension. The researchers evaluated the effects of blood pressure, velocity of internal carotid artery blood flow and WMH on the blood pressure data of 694 community residents (69.6 ± 0.8) and (72.6 ± 0.7) years, and (73.0 ± 1.0) Brain MRI and internal carotid artery ultrasound data at the age of. Compared with the age of 70 at age 73, diastolic blood pressure and mean blood pressure decreased and pulse pressure increased, but the difference in systolic blood pressure was not statistically significant. After correcting for vascular disease and risk factors, multivariate linear regression analysis showed that WMH and hypertension history at age 73 (β = 0.13, P <
