ObjectiveTo investigate the effect of target organ damage in dipper and non dipper type hypertension patients. MethodsTwenty-four hour ambulatory blood pressure of 56 cases patients with essential hypertension was carried out by using ambulatory blood pressure monitoring, then the patients were divided into dipper group (28 cases) and non dipper group (28 cases) according to the type of blood pressure, and were detected coronary CTA, MRI and fundus examination and the target organ damage were compared between two groups. ResultsThe extent of damage of target organ in dipper group was significantly milder than that of non dipper group(P＜0.05). ConclusionsAmbulatory blood pressure monitoring can predict target organ damage in patients with essential hypertension, and has important clinical significance for hypertension prevention and control.
