To study the relation between the average level and variability of blood pressure (VBP) obtained by ambulatory monitoring (AMBP) and the geometric pattern (GP) of the left ventricle (LV) obtained by echocardiography (ECHO) in patients with hypertension (Hy)AMBP and ECHO were performed in 37 patients with Hy, divided into three groups: group A--11 women using antihypertensive therapy (AH); group B--15 men using AH and group C--7 male and 4 female without AH. The GP of LV was obtained by ECHO based on mass index (MI) and relative thickness of the wall (RTW). Mean systolic (MSBP) and diastolic (MDBP) were analyzed during daytime (DT) and nighttime (NT) periods. VBP was defined by mean standard deviation (SD) of mean pressures considered.In G-A, there was a significant association between the MI and both VBP and MSBP (r = 0.65 and p0.005, r = 0.61, and p0.005, respectively), and MSBP and VBP during the DP (r = 0.64 and p0.005, r = 0.75, and p0.005). In G-B, there was a relation between the LVRTW (r = 0.55 and p0.005), and MSBP during the DP (r = 0.65 and p0.005). In G-C, there was a significant association (p0.005) between the MI and the MDBP in the DP and with the MSBP in the NP (r valueS ranged from 0.51 to 0.66). There was also a significant relation (p0.005) between the LVRTW and the SD of all variables in both DP and NP (r ranged from 0.47 to 0.78 and mean diastolic in the wakeful period (r = 0.42 to 0.78) and MDBP in the DP (r = 0.42 and p0.05).Both the increase in VBP and the mean BP are involved in the changes of LVGP in Hy. |
