This patient has preeclampsia and needs treatment of her hypertension and close follow-up. In the past, there was concern that rigorous drug treatment would harm the fetus. Approximately 5%- 1% of all pregnant women develop preeclampsia which is defined as new-onset hypertension with BP > 140/90 mmHg and proteinuria > 300 mg/24h after 20 weeks of gestation.Studies now show benefit in controlling blood pressure with drugs, but ACE inhibitors and angiotensin receptor blockers (ARB) are contraindicated because they cause renal abnormalities in the fetus. Women who develop hypertension during pregnancy have a higher risk of developing hypertension in later life.Preeclampsia does not improve during the third trimester, it leads to premature birth or low- birth-weight babies, and injures the placenta.
