This systematic review and meta-analysis of 32 studies (n=3558) found limited evidence that peripartum interventions meaningfully reduce long-term cardiovascular risk in women with hypertensive disorders of pregnancy. Most pharmacologic and nutraceutical interventions showed no significant short-term blood pressure benefit, whereas postpartum remote blood pressure monitoring/self-management consistently reduced systolic and diastolic BP up to 1 year. However, data on long-term cardiovascular outcomes are sparse, follow-up is short, and trial quality is limited, preventing firm conclusions about risk modification beyond blood pressure.
