Abstract:
Objective To study the blood pressure changing patterns in normal pregnancy and pregnancy induced hypertension(PIH). Methods 24 hour ambulatory blood pressure monitoring (ABPM) were performed in 38 cases of normal pregnancy and 36 cases of PIH during 18～20,28～30 and 38～40 gestational week. Results The 24 hour mean blood pressure were increased with pregnancy advanced. In normal pregnancy, a typical circadian rhythm of blood pressure pattern was shown that it increases during the day and decreased during the night with the disparity of (16.3? 4.1)%, (14.1?3.2)% and (15.7?2.0)% in three different gestational week respectively. In moderate and severe PIH, the 24 hour mean blood pressure,blood pressure load and the frequence of abnormal rhythm were significantly higher than those in mild PIH and normal pregnancy, while the disparity between day and night blood pressure was lower. Conclusion The blood pressure patterns show a typical circadian rhythm in most normal pregnancy. The more severe the PIH is, the higher rate of abnormal blood pressure rhythm occured.
