Over the 17-year follow-up, the adjusted hazard ratio (aHR) for stroke in women with a history of pre-eclampsia/eclampsia was 2.05 (95% confidence interval, CI = 1.67-2.52, p<0.001). The 17 years overall risks of both ischemic and hemorrhagic stroke were 1.98 and 3.45, respectively (p<0.001). The stroke subtypes, hemorrhagic and ischemic, had different time trend risks, and hemorrhagic stroke risks kept higher than that of ischemic stroke. The ischemic stroke risk peaked during 1-3 years after childbirth (aHR=3.09). The hemorrhagic stroke risk peaked during 3-5 years (aHR=7.49).
