Purpose: To determine the predictors of persistent hypertension post-preeclampsia in a single center in Chinese patients. Materials and Methods: Clinical/demographic, obstetric, and biochemical data were collected during presentation and at six weeks' follow up period post-delivery from women with preeclampsia between October 2014 to September 2015. Results: Out of 198 patients enlisted, follow up (six weeks) data was accessible for 173 patients, out of which 143 (82.7%) and 30 (17.3%) patients had mild and severe preeclampsia, respectively. At the time of followup (six weeks), persistent hypertension was recorded in 61 (35.3%) patients. There was no significant association/difference noted for age, BMI, parity, and pregnancy duration in persistent hypertension group vs. normotensive group. Significantly low platelets count (p = 0.001) and low birth weights (p < 0.001) were noted in the persistent hypertension group. Patients encountering persistent hypertension at followup (six weeks) were observed to be mostly having severe preeclampsia earlier in contrast to normotensive group (p < 0.001). There was no association of variables with persistent hypertension; although, patients having severe preeclampsia were previously found to encounter persistent hypertension 7.1 times more compared to patients having mild/moderate preeclampsia (95% CI [confidence interval] 1.4–31.4; p = 0.007). Conclusion: Persistent hypertension was noted to be extremely frequent post six weeks of delivery in preeclampsia patients (particularly severe preeclampsia) in China, irrespective of parity as well as age.
