Physicians' Perspective Toward Hypertensive Disorders of Pregnancy and Future Cardiovascular Diseases in Japan

Aim: Hypertensive disorders of pregnancy (HDP) are among the obstetric complications reportedly associated with later-life cardiovascular disease (CVD). This study examined physicians' recognition of reproductive history by elucidating their attitude and knowledge. Methods: This study included council members of the Japan Atherosclerosis Society. An Internet-based survey was conducted between August 9 and September 9, 2022. Results: A total of 137 council members completed the questionnaire (response rate: 36%). In terms of the internal medicine subspeciality of the participants, endocrinology was the most common (46%), followed by cardiology (38%). About 70% of the participants considered reproductive history to be important and obtained more information than those who considered it otherwise. In the questionnaire for knowledge about HDP and future diseases, physicians correctly answered 6.8 of 9 questions. Endocrinologists were more likely to ask regarding reproductive history at the initial visit than cardiologists (82.5% vs. 61.5%; p=0.012) and obtained more information from women below 50 years old. Contrarily, cardiologists obtained information on reproductive history from older women (those approaching menopause and those in their 60s and 70s). Conclusion: We found that physicians had a high level of knowledge about HDP and the importance of reproductive information. However, the manner of obtaining information, including the target population, differed depending on the subspeciality. In the future, effective interventions for women with a history of HDP need to be developed in order to encourage physicians to obtain reproductive information to prevent CVD.
