Effect of dynamic curve elderly hypertension on cardiac function

Objective To study the effect of the elderly dipper and non-dipper hypertension on the left ventricular function. Methods Seventy-eight patients with StageⅠ～Ⅱ essential hypertension were divided into the dipper group and the non-dipper group, with 39 cases in each group. Fifty-one healthy individuals were selected as the control group. Ambulatory blood pressure and ultrasound echocardiography were employed to detect the relevant parameters of the three groups for statistical analysis. Results The structure and function of left ventricle in the non-dipper group showed significant changes compared with the control group (P0.01). The changes of LVDd in the dipper group showed no statistically significant difference with that in the control group. 24 h SBP, dSBP, nSBP, SBP in non-dipper group were significantly higher than those in the dipper group and the control group (P0.01), while 24 h DBP, dDBP, DBP showed no statistically significant difference. Conclusion Non-dipper hypertension are more prone to diastolic functional abnormalities than dipper hypertension.
