Retrospective chart review of UAMS deliveries between 2009-2011 Inclusion criteria: ▪Hypertensive disorder of pregnancy ▪F/u visit occurring 1-14 days PP Exclusion criteria: ▪CHTN on meds Results BP Range at first PP Visit (1-14 days PP) Antihypertensive N=201 No Antihypertensive N=199 P Value S <140 and D <90 58 (28.86%) 86 (43.22%) 0.0112 S 140-149 or D 90-99 65 (32.34%) 60 (30.15%)   S 150-159 or D 100-109 50 (24.88%) 30 (15.08%) S >160 or D >110 28 (13.93%) 23 (11.56%) Results Conclusions 1,083 pregnancies complicated by Gestational HTN, pre-eclampsia, eclampsia, HELLP, or CHTN with superimposed preeclampsia 683 excluded from analysis due to no f/u visit in postpartum days 1-14 Maternal characteristics (including age, race, BMI, gravidity, parity) were not significantly different between the treated and untreated groups The distribution of BP ranges between groups was significantly different with more normal BPs in the untreated group & more elevated BPs in the treated group In this group of subjects, the appropriate patients are being chosen for PP HTN treatment Future study to evaluate BP control with nifedipine vs labetalol
