Summary Hypertensive disorders of pregnancy are known to be a risk factor for future cardiovascular diseases. In contrast, there is a paucity of data on the not so distant future prognosis of hypertensive disorders of pregnancy. In the present study, we evaluated the incidence of the diseases causing cardiovascular problems (hypertension, diabetes mellitus, dyslipidemia and metabolic syndrome) 5 years after delivery in Japanese women with hypertensive disorders of pregnancy. We performed a double-cohort study and compared medical conditions between women with and without a history of hypertensive disorders of pregnancy. A total of 1513 women who participated in the cohort study were invited to undergo a medical checkup 5 years after the index delivery, of whom 829 responded. After excluding pregnant and lactating women at the time of examination, 25 women with hypertensive disorders of pregnancy and 746 control subjects were analyzed. The incidence of hypertension was significantly higher among women with hypertensive disorders of pregnancy than women who were normotensive during pregnancy (24.0 vs. 2.5%, P<0.001). They were also at an increased risk of subsequent hypertension 5 years after the index delivery, after adjusting for confounding factors such as age, body mass index, family history of hypertension and salt intake (odds ratio 7.1, 95% CI, 2.0-25.6, P<0.003). These is no significant difference in the incidence of diabetes mellitus, dyslipidemia and metabolic syndrome. In conclusion, hypertensive disorders of pregnancy are strong risk factors for subsequent hypertension only 5 years after delivery.
