What is the recommended blood pressure target during pregnancy for a patient with a history of chronic hypertension?

The recommended blood pressure target during pregnancy for a patient with a history of chronic hypertension is below 140/90 mm Hg. This target is established by national and international guidelines that aim to balance the reduction of potential risks associated with high blood pressure while maintaining adequate blood flow to the placenta and the fetus.

Setting the target below 140/90 mm Hg allows for managing chronic hypertension effectively without being overly strict, which could pose risks of maternal hypotension and compromise placental perfusion. While aiming for levels below 130/80 mm Hg can be appropriate for some, the broader consensus prioritizes a target that avoids complications.

Finding the right balance in blood pressure management during pregnancy is crucial for both maternal and fetal health, which is why focusing on maintaining blood pressure under 140/90 mm Hg is standard practice for pregnancies complicated by chronic hypertension.
