Pregnancy Hypertension Significantly Raises Women’s Risk of Cardiovascular Disease, Study Finds

A recent large-scale study from Intermountain Health has revealed that women who experience hypertensive disorders during pregnancy face a markedly higher risk of developing serious cardiovascular conditions—including heart failure, stroke, heart attack, and death—within five years after childbirth. The findings highlight pregnancy hypertension, including gestational hypertension, preeclampsia, and eclampsia, as critical predictors of long-term cardiovascular health risks, emphasizing the importance of early identification and management to improve outcomes for affected women.

Key Findings and Study Details

The retrospective study analyzed data from 218,141 live births involving 157,606 women across 22 hospitals between 2017 and 2024. Researchers reviewed electronic medical records for hypertensive disorders of pregnancy (HDP), including chronic hypertension, gestational hypertension, preeclampsia, and eclampsia, and tracked cardiovascular outcomes up to five years postpartum. Approximately 19.7% of women were diagnosed with an HDP, most commonly during their first pregnancy.

Women with HDP showed significantly increased cardiovascular risk factors such as obesity, smoking, diabetes, hyperlipidemia, depression, and lower socioeconomic status. The severity of hypertension during pregnancy correlated with the magnitude of future risk: women with chronic hypertension plus severe HDP (e.g., eclampsia) had the greatest likelihood of cardiovascular events. Specifically, risks of heart failure were 3 to 13 times higher, stroke risk increased 2 to 17-fold, and heart attack and coronary artery disease risks rose 3 to 7 times compared to women without HDP. These elevated risks extended to a 1.4 to 4 times greater risk of death within five years after delivery.​

Expert Commentary

Kismet Rasmusson, NP, lead investigator and advanced practice clinician at Intermountain Health, emphasized the importance of recognizing these pregnancy-related risks: “Any form of hypertension during pregnancy significantly increases cardiovascular risk and the risk of death,” she stated. “This risk is particularly pronounced in women with severe forms of hypertensive disorders, such as eclampsia. Despite these alarming statistics, many women remain unaware of the long-term health implications, underscoring the need for improved screening and care”.​

Additional expert sources reinforce this message. Janet Wright, MD, Director of CDC’s Division for Heart Disease and Stroke Prevention, highlighted that treating hypertension to target blood pressure levels during pregnancy improves outcomes without increasing risks to the baby. Furthermore, a 2023 genetic study published in JAMA supported the notion that hypertensive disorders in pregnancy are independently associated with higher risk of coronary artery disease and stroke later in life, even after accounting for traditional cardiometabolic risk factors, cementing HDPs as important cardiovascular risk factors.​

Context and Public Health Implications

Hypertensive disorders affect around 10% of pregnancies globally and represent a leading cause of maternal and neonatal morbidity and mortality. Beyond the immediate pregnancy complications like preterm birth, low birth weight, and placental abruption, pregnancy hypertension sets the stage for accelerated cardiovascular aging and disease in mothers. Epidemiological studies have shown that women with a history of HDP have about twice the risk of developing cardiovascular disease compared to women with normotensive pregnancies.​

These findings are especially significant in light of increasing prevalence rates of pregnancy hypertension in recent decades and persistent health disparities affecting populations with lower socioeconomic status and comorbidities. Proactive identification of HDP before, during, and after pregnancy, coupled with long-term cardiovascular risk monitoring and lifestyle interventions, are essential strategies to mitigate adverse outcomes.​

Potential Limitations and Balanced Perspectives

While the study provides compelling evidence on cardiovascular risks associated with pregnancy hypertension, it is observational and retrospective in nature; thus, causal inferences should be drawn cautiously. Confounding factors such as socioeconomic variables and pre-existing health conditions may influence outcomes. Additionally, the mechanisms linking HDP to later cardiovascular disease are not fully understood, with contributions from genetic, vascular, and inflammatory pathways under investigation.​

Practical Takeaways for Readers

For women and healthcare providers, awareness that hypertension during pregnancy is more than a temporary concern can drive better health decisions. Women with a history of HDP should be counseled about their elevated cardiovascular risk and monitored regularly after delivery. Lifestyle modifications including healthy diet, regular exercise, weight management, and smoking cessation remain foundational preventative strategies. Moreover, timely clinical management of blood pressure and follow-up screening can help reduce risk of heart disease and stroke later in life.
