    Abstract:
    AIM: To study a relationship of the magnitude of structural changes in the left ventricle (LV) to the mean daily pulse blood pressure (PBP) in patients with hypertensive disease (HD). MATERIALS AND METHODS: 70 male patients (mean age 49 +/- 1 years) with stages I (n = 54) to 11 (n = 16) HD. LV mass (LVM) was estimated by echocardiography according to the formula derived by R. B. Devereux et al. and normalized to body surface area [the LVM index (LVMI)]. The relative thickness index (RTI) for the posterior wall (PWRTI) and ventricular septum (VSRTI) was calculated as a ratio of the sum of PWRTI and VSRTI to the LV end-diastolic size. LVMI > 125 g/m2 was considered to be a criterion for LV hypertrophy (LVH). 24-hour blood pressure (BP) monitoring was performed with a Spacelabs-90207 device (USA). According to the 24-hour PBP value, the patients were divided into 2 groups: 1) those (n = 17) having PBP24 > 53 mm HG and 2) those (n = 53) having PBP24 < 53 mm Hg. RESULTS: Group 1 patients were found to have significantly higher LVMI, LV WRTI, and incidence of LVH and a complex of changes in the BP profile as higher values of 24-hour systolic, diastolic and mean BP, PBP, and BP variations. Multiple regression analysis revealed a highly significant contribution of PBP24 to the development of LVH. CONCLUSION: The pedictive value of PBP as an index that characterizes a dynamic pressure load in regard to LV structural changes is higher than that of mean BP as a static load index and a BP variation index.
