Pak J Med Health Sci Jan ;8(1):142-5.

Aim: To estimate the frequency of recurrence of pregnancy induced hypertension in 2nd pregnancy. Study design: Descriptive case series Place and duration of study: The Department of Obstetrics & Gynecology, Unit- II, Sir Ganga Ram Hospital, Lahore. six month duration from Aug 01, 2009 to Feb 01, 2010. Methods: Eighty patients were selected in accordance with inclusion criteria. A detailed history and examination was done. At each antenatal visit, blood pressure was checked. The urine was examined for proteinuria. An obstetrical ultrasonography was performed to confirm single viable pregnancy. The patients were followed from 20 weeks of gestation, fortnightly upto 34 weeks Results: Out of 80 patients having PIH in previous pregnancy, only 20 patients (25%) had recurrence of gestational hypertension, 7 patients (8.75%) had pre-eclampsia in current pregnancy while 53 patients (68.9%) had normotensive current pregnancy. None of these patients were observed to have eclampsia in second pregnancy. Thus overall risk of recurrence of PIH in second pregnancy, irrespective of the type of disorder was 25% and that of pre-eclampsia was 8.75% while to know the risks of recurrence of eclampsia, large population based study is required.
