Sumario: | Background: Unlike Europe and the United States, Japan has seen numerous maternal deaths from hemorrhagic strokes related to hypertensive disorders of pregnancy (HDP). This study retrospectively analyzed deaths associated with HDP-related hemorrhagic stroke in Japan to determine the number of deaths that may have been prevented with blood pressure control during pregnancy. Methods: This study included maternal deaths related to hemorrhagic stroke cases. The proportion of patients without proteinuria whose blood pressure exceeded 140/90 mmHg between 14+0 and 33+6 weeks of gestation were determined. Lastly, the application of tight antihypertensive management was evaluated. Results: Among 34 HDP-related maternal deaths, 4 cases involved patients without proteinuria whose blood pressures exceeded 140/90 mmHg between 14+0 and 33+6 weeks of gestation. These included two chronic hypertension and two gestational hypertension cases. None of the patients received antihypertensive agents, and their blood pressures were managed leniently. Conclusion: Among HDP-related hemorrhagic stroke deaths in Japan, only a few cases of maternal death could have been prevented with tight blood pressure management, as described in the CHIPS randomized controlled trial. Therefore, to prevent HDP-related hemorrhagic stroke in Japan, new preventive strategies during pregnancy should be established. |
