| Abstract: | Forearm venous tone was measured in two groups of pregnant women: one group with pregnancy-induced hypertension and the other group with normal blood pressure. The women with pregnancy-induced hypertension were venoconstricted in the forearm (P less than 0.01) compared with the pregnant women with normal blood pressure. However, there was no difference in venous tone between the women with pregnancy-induced hypertension and non-pregnant women. There was an inverse correlation between mean arterial blood pressure and forearm venous tone (r = -0.581, P less than 0.001) for all the pregnant women studied. Further evaluation of peripheral venous tone may provide valuable information about the pathophysiology and treatment of women with pregnancy-induced hypertension. |
