Which patient profile carries the highest risk of developing preeclampsia?

The patient profile that indicates the highest risk of developing preeclampsia is the one that involves a prior history of preeclampsia. It has been well-documented that women who have previously experienced preeclampsia during a past pregnancy are at a significantly increased risk of developing the condition again in subsequent pregnancies. The physiological and genetic factors influencing this risk are complex, but a previous occurrence is a clear indicator of susceptibility.

Considering the other profiles, while familial history, previous miscarriages, and smoking can influence pregnancy outcomes, they are not as strongly correlated with the development of preeclampsia as a prior experience of the condition itself. Family history can contribute to risk but is less definitive compared to personal patient history. Miscarriages are linked to various factors but do not specifically indicate an increased risk of preeclampsia, and smoking, while harmful and associated with other complications, does not have the same strong evidence linking it to preeclampsia risk as a previous episode of the condition.
