Abstract

Objective:

To investigate the relationship of the parameters of 24 hours ambulatory blood pressure monitoring(24hABPM) or circadian rhythm and the variation of cardiac structure and function in middle aged patients with essential hypertension.

Design and Method:

The middle aged patients with essential hypertension were chosen, whose blood pressure were more than 140/90mmHg without Other organic diseases. Patients were measured by 24hABPM and UCG. According to the results of 24hABPM, patients were divided into four groups, and the PP, PPI and BPL were calculated. Multivariate regression analysis was used to investigate the relationship of ABPM results and the cardiac structure.

Results:

24 hDBP,dDBP,nDBP of male group were significantly higher than the female group. There have been statistical difference (p < 0.05). In male group, EF values of dippers hypertension group, shallow or non-dippers hypertension group, and extreme-dippers hypertension group were higher than reverse-dippers hypertension group (p < 0.01). PPI has greatest influence on heart function damage.

Conclusions:

The classification of the circadian rhythm has instructional significance for ventricular remodeling. PPI has greatest influence on heart function damage.
