中老年男性人群卒中风险评估及相关危险因素分析

目的 探讨应用脑血管功能积分值检测评估中老年男性人群卒中风险及与相关危险因素暴露水平的关系。方法 选取完成健康体检并行脑血流动力学检测的280例45岁以上男性人群为研究对象，以脑血管功能积分值（cerebral vascular functional accumulative scores，CVFAS）75分为截点，分为卒中高危组（＜75分，82例）和卒中低危组（≥75分，198例），分析不同年龄段CVFAS变化和卒中高危个体检出率，并比较卒中高危组和低危组之间危险因素暴露水平，分析CVFAS与危险因素的相关性。结果 本研究人群CVFAS随着年龄增加而逐渐降低，卒中高危个体检出率达29.3%（82/280），并随着年龄递增而上升，70岁以上达60.0%。卒中高危组的年龄、吸烟史、高血压史、糖尿病史、腰围、体脂含量、收缩压（systolic blood pressure，SBP）、舒张压（diastolic blood pressure，DBP）、空腹血糖、TC、LDL-C、Hcy、肱踝脉搏波传导速度（brachial-ankle pulse wave velocity，baPWV）、颈动脉内膜中层厚度（carotid intima-media thickness，CIMT）均高于低危组，HDL-C低于低危组，差异均有统计学意义。相关性分析显示，CVFAS与年龄（r =-0.314，P =0.007）、腰围（r =-0.295，P =0.009）、体脂含量（r =-0.324，P =0.006）、SBP（r =-0.387，P =0.005）、DBP（r =-0.327，P =0.006）、TC（r =-0.219，P =0.014）、LDL-C（r =-0.325，P =0.006）、空腹血糖（r =-0.289，P =0.009）、Hcy（r =-0.216，P =0.014）、baPWV（r =-0.349，P =0.005）、CI MT（r =-0.209，P =0.013）负相关，与HDL-C正相关（r =0.258，P =0.011）。Logistic回归分析显示，年龄（OR 1.257，95%CI 1.118～1.359，P =0.001）、高血压病史（OR 1.524，95%CI 1.259～1.894，P＜0.001）、体脂含量（OR 1.493，95%CI 1.214～1.876，P =0.001）、SBP（OR 1.897，95%CI 1.684～2.697，P =0.001）、空腹血糖（OR 1.356，95%CI 1.214～1.651，P =0.001）、LDL-C（OR 1.675，95%CI 1.327～1.956，P＜0.001）、Hcy（OR 1.295，95%CI 1.158～1.413，P =0.001）、baPWV（OR 1.258，95%CI 1.149～1.524，P =0.002）为CVFAS异常的独立危险因素。结论 CVFAS降低（＜75分）与卒中危险因素暴露水平密切相关，运用CVFAS检测评估筛查卒中高危人群，是简便、可行的检查手段。

Evaluation of Stroke Risk Profile and Its Correlation with Related Risk Factors in Middle-aged and Eldly Male Population

Objective To evaluate stroke risk profile using cerebral vascular functional accumulative scores
(CVFAS) and analyze the relationship between the score and exposure level of risk factors in
middle- aged and old male population.
Methods A total of 280 male people aged more than 45 years who had completed health checkupand cerebral hemodynamic examination from People's Liberation Army General Hospital No. 8
Medical Center from February 2016 to November 2016 were included in this study.All subjects
were divided into two groups according to the cut off point of CVFAS, high-risk group (CVFAS<75
score, n =82) and low-risk group (CVFAS≥75 score, n =198). To analyze the change of CVFAS and
the detection rate of high-risk individuals of stroke in different age groups, compare the exposure
level of risk factors between the two groups, and analyze the correlation between CVFAS and risk
factors of stroke.
Results The CVFAS score gradually decreased with age, the detection rate of high-risk individuals
of stroke was 29.3% (82/280), this rate increased with age and reached up to 60.0% in people over
70 years. Compared with low-risk group, the proportion of smoking, hypertension, diabetes were all
much more higher in high-risk group (all P <0.05), in addition, the levels of age, waist circumference
(WC), body fat (BF), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma
glucose (FPG), TC, LDL-C, Hcy, brachial-ankle pulse wave velocity (baPWV), carotid intimamedia
thickness (CIMT) were also far more higher in high-risk group, but HDL-C were much lower
in high-risk group (P <0.05). Correlation analysis showed a negative correlation between CVFAS
and age (r =-0.314, P =0.007), WC (r =-0.295, P =0.009), BF (r =-0.324, P =0.006), SBP (r =-0.387,
0.005), DBP (r =-0.327, P =0.006), TC (r =-0.219, P =0.014), LDL-C (r =-0.325, P =0.006), FPG (r =-0.289,
P =0.009), Hcy (r =-0.216, P =0.014), baPWV (r =-0.349, P =0.005), CIMT (r =-0.209, P =0.013) and a
positive correlation with HDL-C (r =0.258, P =0.011). Logistic regression analysis revealed that age
(OR 1.257, 95%CI 1.118-1.359, P =0.001), hypertention (OR 1.524, 95%CI 1.259-1.894, P <0.001),
BF (OR 1.493, 95%CI 1.214-1.876, P =0.001), SBP (OR 1.897, 95%CI 1.684-2.697, P =0.001), FPG
(OR 1.356, 95%CI 1.214-1.651, P =0.001), LDL-C (OR 1.675, 95%CI 1.327-1.956, P <0.001), Hcy
(OR 1.295, 95%CI 1.158-1.413, P =0.001), baPWV (OR 1.258, 95%CI 1.149-1.524, P =0.002] were
independent risk factors of CVFAS abnormality.
Conclusions The decreased CVFAS (CVFAS<75 score) was closely correlated with the exposure
levels of risk factors in high-risk individuals of stroke. Using CVFAS to screen the high-risk
individuals of stroke is a convenient and feasible method, which is helpful to early prevention of
stroke.
