Diagnostic value of head upright tilt testing on orthostatic hypotension in patients with senile hypertension / 中国医师进修杂志

ABSTRACT

Objective To evaluate diagnostic value of head upright tilt testing (HUTT) on orthostatic hypotension (OH) in patients with senile hypertension,and explore its efficacy and safety.Methods One hundred and sixty-six patients with senile hypertension were selected,and the patients were divided into 2 groups according to HUTTexperiment group (completed HUTT,86 cases) and control group (unfinished HUTT,80 cases).The blood pressure change was observed.The detection rate of OH and incidence of unexpected event were compared between 2 groups.Results The detection rate of OH in experiment group was 31.4％ (27/86),in control group was 17.5％ (14/80),and there was statistical difference (P ＜ 0.05).The incidence of unexpected event in experiment group was 0,in control group was 6.2％ (5/80),including 3 patients with dizziness amaurosis,unstable presyncope symptoms and fall,and 2 cases with syncope and sudden fall.There was statistical difference in incidence of unexpected event between 2 groups (P ＜ 0.05).Conclusions The use of HUTT in patients with senile hypertension can significantly improve the detection rate of OH,but also significantly reduce the incidence of unexpected event.The method is safe,effective,worthy of clinical promotion.
