Relationship between orthostatic blood pressure and atheriosclerosis in very old people
Abstract：Objective To study the relationship between orthostatic blood pressure and atheriosclerosis in very old people.Methods Two hundred and twenty-seven very old people admitted to our hospital from June 2014 to December 2015 were randomly divided into orthostatic normotension (ONT) group (n =151),orthostatic hypotension (OH) group (n =52),and orthostatic hypertension (OHT) group (n=24) according to their postural blood pressure.Their blood flow in 4 extremities was measured by Doppler ultrasonography.Their orthostatic blood pressure,brachialankle pulse wave velocity (baPWV) and ankle brachial index (ABI) were compared.Results The age was older and the fall score was significantly higher in OHT group than in ONT group (P＜0.05,P＜0.01).The right and left ABI were significantly lower in OH group than in ONT group (P＜0.01).Multivariate logistic regreassion analysis showed that low ABI was one of the independent risk factors for OH (OR=20.776,95 ％CI:7.449-57.947,P=0.000).The incidence of OH was 1.035-fold higher in patients with a high fall score than in those with a normal fall score (95％CI:1.013-1.057,P=0.002).Age was one of the independent risk factors for OHT in very old people (OR=1.169,95％CI:1.014-1.348,P=0.031).Conclusion Low ABI is one of the independent risk factors for OH and age is one of the independent risk factors for OHT in very old people.Fall score can predict the risk of OH.
