Relação do nível médio e variabilidade da pressão arterial com a geometria do ventrículo esquerdo na hipertensão arterial sistêmica

PURPOSE--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) METHODS--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. RESULTS--In G-A, there was a significant association between the MI and both VBP and MSBP (r = 0.65 and p
