Pregnancy is a critical window to reshape decades of health outcomes
A new scientific statement from the American Heart Association reframes pregnancy not as a contained chapter in a woman's life, but as a revealing passage that can illuminate the decades ahead. Six complications — from gestational hypertension to fetal loss — have been identified as significant harbingers of future cardiovascular disease, affecting between 10 and 15 percent of pregnant women, with disproportionate weight falling on Black, Hispanic, and Asian women. The medical community is being called to treat the months of pregnancy and the period that follows as a rare and actionable window — one in which early knowledge, if met with care and intention, can redirect the arc of a woman's long-term health.
- Six pregnancy complications — including gestational hypertension, preeclampsia, and gestational diabetes — have been formally linked to cardiovascular disease risks that can more than double a woman's chances of heart attack or stroke later in life.
- The urgency is sharpened by stark numbers: preeclampsia raises cardiovascular risk 2.7-fold, premature birth doubles it, and gestational diabetes multiplies the risk of type 2 diabetes tenfold — yet many women leave obstetric care without being told.
- A critical gap in the system is exposed as women transition out of pregnancy care and back into primary care, often without their obstetricians and general physicians sharing the health history that could trigger preventive action.
- Black, Hispanic, and Asian women bear a disproportionate burden of both adverse pregnancy outcomes and cardiovascular risk factors, yet remain underrepresented in the research that underpins these findings.
- The American Heart Association is urging doctors to treat pregnancy as a 'golden year' — a moment to intervene with lifestyle changes, extended postpartum monitoring, and coordinated care before cardiovascular disease takes hold.
The American Heart Association has issued a landmark scientific statement identifying six pregnancy complications that substantially raise a woman's risk of developing heart disease in the years that follow. Published in the journal Circulation, the statement marks a meaningful shift in how medicine understands pregnancy — not as an isolated event, but as a long-range signal about a woman's cardiovascular future.
Between 10 and 15 percent of pregnant women experience one or more of the identified complications: gestational hypertension, gestational diabetes, premature delivery, low birth weight for gestational age, pregnancy loss, and placental abruption. The numbers attached to each are sobering. Gestational hypertension raises future cardiovascular disease risk by 67 percent and stroke risk by 83 percent. Preeclampsia — a more severe condition involving high blood pressure and organ stress — carries a risk 2.7 times higher. Gestational diabetes elevates cardiovascular risk by 68 percent and multiplies the likelihood of developing type 2 diabetes tenfold. Premature birth and placental abruption each roughly double cardiovascular risk, and fetal loss carries a similarly elevated burden.
Dr. Nisha I. Parikh, who chaired the writing committee, noted that these connections are not anomalies — they are consistent across decades of research and confirmed in nearly every study examined. Yet a critical gap persists: as women move from obstetric care back into primary care, this vital health history is often lost, and the opportunity for early intervention slips away.
The association calls for aggressive prevention and continuous monitoring, beginning with lifestyle changes — heart-healthy eating, adequate sleep, increased physical activity — that should start during pregnancy and continue for life. Breastfeeding is identified as a protective factor against both cardiovascular disease and metabolic disorders. Extended postpartum follow-up and better communication between obstetricians and primary care physicians are also recommended.
The statement draws particular attention to health disparities: Black, Hispanic, and Asian women experience more adverse pregnancy outcomes and carry greater cardiovascular risk, yet remain underrepresented in the research. Dr. Eliza C. Miller, writing in an accompanying editorial, called pregnancy and the postpartum period a 'golden year' — a rare and time-sensitive opportunity for doctors to identify young women at risk and work with them before disease takes root.
The American Heart Association has issued a scientific statement identifying six pregnancy complications that substantially elevate a woman's risk of developing heart disease in the years and decades that follow. The warning, published in the journal Circulation, marks a significant shift in how the medical community understands the long-term health consequences of what happens during pregnancy—consequences that can echo through a woman's entire life.
Between 10 and 15 percent of pregnant women experience adverse outcomes. These include gestational hypertension (high blood pressure during pregnancy), gestational diabetes (diabetes that emerges for the first time during pregnancy), premature delivery before 37 weeks, delivering a baby with weight below what is expected for gestational age, pregnancy loss, and placental abruption. Each of these conditions, the association warns, is tightly linked to cardiovascular disease that develops later. The statement calls for aggressive prevention of these risk factors and continuous monitoring of women who experience them as they transition from obstetric care back into primary care.
The numbers are striking. Gestational hypertension—defined as blood pressure readings of 140/90 mm Hg or higher after 20 weeks of pregnancy in a woman with previously normal readings—increases the risk of future cardiovascular disease by 67 percent and raises the risk of stroke by 83 percent. Preeclampsia, a more severe condition involving high blood pressure plus signs of organ damage to the liver, kidneys, or other vital systems, carries a risk that is 2.7 times higher. Gestational diabetes, meanwhile, elevates cardiovascular disease risk by 68 percent and multiplies by tenfold the risk of developing type 2 diabetes after pregnancy ends.
Premature birth doubles a woman's risk of developing cardiovascular disease and is strongly associated with later heart attacks, strokes, and other cardiovascular events. Placental abruption—the premature separation of the placenta from the uterus—is linked to an 82 percent increase in cardiovascular disease risk. Fetal loss, including stillbirth, nearly doubles the risk of heart disease. Dr. Nisha I. Parikh, who chaired the statement's writing committee, emphasized that these connections are not isolated findings. "The evidence linking adverse pregnancy outcomes to cardiovascular disease later is consistent across many years and confirmed in nearly all the studies we examined," she said. The statement represents a comprehensive review of recent scientific literature on pregnancy complications and cardiovascular disease, with particular attention to health disparities, lifestyle factors, and prevention strategies.
The association notes a critical gap in current research: more studies are needed examining these associations in Black, Hispanic, and Asian women, who experience more adverse pregnancy outcomes and carry a greater burden of cardiovascular risk factors compared to white women. This disparity underscores the urgency of the prevention message.
Parikh stressed that early intervention and prevention of risk factors can stop cardiovascular disease before it starts. "Adverse pregnancy outcomes can be a powerful window for cardiovascular disease prevention if women and their healthcare providers use this knowledge to improve health," she said. The statement recommends that a healthy diet in the three years before pregnancy is associated with lower complication risk. During and after pregnancy, women should adopt heart-healthy eating patterns, maintain adequate sleep, and increase physical activity—interventions that should begin during pregnancy and continue through the postpartum period and the rest of a woman's life.
Breastfeeding emerges as another protective factor. The statement notes that breastfeeding can reduce the risk of cardiovascular disease and metabolic disorders like type 2 diabetes in later life. The association also calls for improved postpartum care: extended follow-up during what some call the "fourth trimester" to detect cardiovascular risk and provide prevention counseling, better communication of health information between obstetricians and primary care physicians, and a brief, targeted health history for each woman to confirm whether she experienced any of the six risk factors during pregnancy.
Dr. Eliza C. Miller, a neurologist who wrote an accompanying editorial, framed pregnancy and the postpartum period as a "critical temporal window" in a woman's life to identify cardiovascular risk and alter her health trajectory. "Pregnancy and the postpartum period should be considered the 'golden year' of opportunity for doctors to identify young women at risk and work with them to improve their future cardiovascular health," Miller wrote. The statement represents a call to action: to see pregnancy not as an isolated event but as a moment that can reshape decades of health outcomes that follow.

The Hearth Conversation Another angle on the story
Why does the American Heart Association care about what happens during pregnancy? Isn't that an obstetrics issue?
Because pregnancy is a stress test on a woman's entire body. If her cardiovascular system can't handle the demands of pregnancy, that's a signal that it may fail later under other stresses. The association is saying: pay attention to what breaks during pregnancy, because it tells you what will break in the future.
So gestational hypertension isn't just a nine-month problem?
No. It's a warning light. A woman with gestational hypertension has a 67 percent higher risk of heart disease later. That's not a small number. And if she develops preeclampsia—the more severe form—her risk jumps nearly threefold. The pregnancy ends, but the risk doesn't.
What about the women who have normal pregnancies? Are they safe?
Mostly, yes. But 10 to 15 percent of pregnant women experience one of these six complications. That's millions of women globally. And the statement points out that Black, Hispanic, and Asian women experience these complications at higher rates and have less research attention paid to them.
What can a woman actually do if she's had one of these complications?
The statement emphasizes lifestyle: diet, sleep, exercise, and breastfeeding if possible. But more importantly, it's calling for doctors to treat pregnancy as a moment to identify risk and then follow these women closely afterward. Right now, many women leave obstetric care and fall into a gap where nobody's watching for the cardiovascular problems that might develop.
So this is really about prevention?
Exactly. Catch the risk during or right after pregnancy, when women are already engaged with healthcare, and you have a chance to prevent disease decades later. Miss that window, and you're trying to fix a heart problem that's already developed.
