Objective To explore the correlation study of cerebral vascular hemo -dynamic index(CVHI) with blood pressure,body mass index (BMI)etc.in outpatients.Methods Participants were outpatients with non -invasive CVHI test,who were selected as study subjects.Height,weight,blood pressure and other general information were investigated and the distribution characteristics of blood pressure,BMI and CVHI were compared in different age and gender groups.Results A total of 28 616 subjects were included in the study.The age range was 11 -99 years. Means of CVHI integral score in males and females were (77.78 ±28.44)points and (79.18 ±27.8)points(t =4.275,P <0.01),and abnormality rates of the score(<75 points)were 30.1% and 28.1%(χ2 =13.444,P <0.01),the differences were statistically significant.CVHI score was decreased and the abnormal rate was increased with aging.Systolic blood pressure was elevated with aging and diastolic blood pressure was higher in middle age subjects (40 -65 years).The proportions of over weighted and obesity in male were 37.5% and 15.4%,which in female were 33.2% and 14.9%(χ2 =70.661,P <0.01).It was especially higher in middle age subjects.Conclusion Degree of injury of cerebrovascular function and level of systolic blood pressure are along with aging.Means of BMI and diastolic blood pressure is higher in middle age population.The rate of high risk individuals in outpatients is about 30%.
