Four medical societies reframe women's heart health as a lifelong risk story starting at puberty

Heart disease does not announce itself at menopause. According to a new set of landmark reports published Monday in the journal Circulation, the seeds of cardiovascular risk in women can be planted as early as a girl's first menstrual period — and they shift, accumulate, and sometimes accelerate at every hormonal turning point in between.

Published October 26, 2026, the three papers represent a collaborative effort by the American Heart Association (AHA), the American College of Obstetricians and Gynecologists (ACOG), the American Academy of Pediatrics (AAP), and the Society for Maternal-Fetal Medicine. Together they lay out a unified, life-stage framework for understanding and acting on women's cardiovascular risk — one that asks pediatricians, OB/GYNs, and cardiologists to treat their work as connected rather than siloed.

Women experience their healthcare across clinical specialties, but it often is fragmented or disconnected. Specifically, these reports connect the dots for clinicians, for patients, and across health domains so that care is holistic and begins in adolescence.— Dr. Sadiya Khan, chair of the writing group and Magerstadt Professor of Cardiovascular Epidemiology, Northwestern University Feinberg School of Medicine

The publications represent, in the words of Dr. Stacey E. Rosen, "a paradigm shift in how we look at women's cardiovascular and brain health." Rosen, who served as immediate past volunteer president of the AHA and contributed as a co-author, said the papers examine a woman's life in distinct stages, each presenting opportunities for early detection, risk factor identification, and treatment.

For years, the monthly hormonal fluctuations that define female biology made cardiovascular research more complicated, and scientists often sidelined women's hormones as a variable. The new reports argue that was exactly the wrong call: the AHA states that estrogen, estradiol, and progesterone "impact cells in blood vessels, in the brain, in heart muscle" and influence cholesterol levels, the stickiness of blood cells, inflammation, blood pressure, and the body's stress response.

If you appreciate the understanding that these hormones are not just affecting the uterus, ovaries and fallopian tubes but affecting in a rhythmic way every part of the cardiovascular system and brain, you can appreciate why these fluctuations or issues related to these hormones in women have an enormous impact.— Dr. Stacey E. Rosen, immediate past volunteer president, American Heart Association

The reports also push back on the classic image of heart disease. Dr. Esther S.H. Kim, director of the Center for Women's Cardiovascular Health at Atrium Health and a professor at Wake Forest University School of Medicine, described the prevailing assumption in blunt terms: the default mental image is "a Homer Simpson-type of person — a middle-aged or older man with very obvious cardiovascular risk factors. But Marge Simpson can also have heart disease." And Marge's disease, Kim noted, may look different — more likely to involve microvascular coronary disease, heart failure with preserved ejection fraction, or spontaneous coronary artery dissection, all of which require specific diagnostic tests that doctors may not order if they are not thinking about them.

The framework organizes risk into four female life stages, with pregnancy treated as a 'stress test' event that can occur across stages and unmask hidden vulnerabilities.

STAGE 1 — PERIMENARCHE (roughly ages 8–15): The years surrounding a girl's first period carry more cardiovascular weight than most people — or doctors — realize. According to Khan, the reports classify a first period arriving before age 10 as a "cardiovascular risk enhancer," a designation that may reflect the fact that early menstruation frequently accompanies metabolic concerns, such as excess fat tissue, that can carry forward into adulthood. Irregular or absent periods can be early flags for conditions such as PMOS (polyendocrine metabolic ovarian syndrome, formerly called PCOS), which raises cardiovascular risk through high androgen levels linked to inflammation, a poor cholesterol profile, and insulin resistance. Heavy or unpredictable periods and mood symptoms tied to premenstrual syndrome can also undermine the exercise, sleep, and diet habits that form the foundation of a heart-healthy life. And the body changes of puberty can trigger mental health challenges — body-image issues, depression, disordered eating — all associated with cardiovascular risk.

Heart health for women doesn't start at menopause. Puberty is a big turning point.— Dr. Amanda M. Perak, associate professor of pediatrics and preventive medicine, Northwestern University, and pediatric cardiologist, Ann & Robert H. Lurie Children's Hospital of Chicago

STAGE 2 — OVARIAN CYCLING, INCLUDING PREGNANCY (roughly ages 15–44): During the reproductive years, women are overall less likely than men to develop heart disease — an edge the reports refer to as "the female advantage" — attributed largely to the cardioprotective effects of estrogen and other hormones that shift throughout the menstrual cycle. But that advantage is not unconditional. People with irregular or absent cycles may have hormones out of balance and a higher cardiovascular risk. Hormonal contraception is another factor to weigh: according to the sources, combined hormonal contraceptives that include both estrogen and progesterone can elevate the risk of blood clots.

Pregnancy itself functions as a cardiovascular stress test. Adverse pregnancy outcomes — hypertensive disorders such as preeclampsia, gestational diabetes, preterm birth, or hemorrhage — can significantly elevate future heart disease risk, in some cases doubling or tripling it, according to the multi-source summary. Khan noted that preeclampsia in pregnancy or postpartum was among the first conditions to make the connection between reproductive health and future cardiac risk visible to researchers.

Historically, reproductive health has been squarely in the OB/GYN space, and cardiovascular health has been reserved for cardiologists.— Dr. Emily Lau, cardiologist and investigator, Massachusetts General Hospital, and assistant professor of medicine, Harvard Medical School

STAGE 3 — PERIMENOPAUSE (roughly ages 45–51): Hormonal fluctuations during the transition to menopause accelerate metabolic changes beyond what typical aging would produce — rising LDL cholesterol, increasing insulin resistance, and accumulating abdominal fat. This stage marks an early acceleration point for cardiovascular risk.

STAGE 4 — POSTMENOPAUSE (age 51 and beyond): The loss of estrogen removes its protective effects, and this is when women experience the highest rates of heart attacks, strokes, and heart failure. The reports note that premature menopause heightens these risks further. The central argument of the entire framework is that much of this late-life burden is preventable — but only if action starts decades earlier.

Heart disease and other forms of cardiovascular disease don't suddenly become relevant when we become older women.— Dr. Stacey E. Rosen, immediate past volunteer president, American Heart Association

For clinicians, the reports offer a unified approach spanning pediatrics, primary care, endocrinology, obstetrics, gynecology, and cardiology. For patients, the message is more direct: know the symptoms of cardiovascular disease, bring them up with your doctor, and be persistent if you feel ignored. Dr. Natalie A. Cameron, an internal medicine specialist at Northwestern who led the writing team for one of the documents, put the goal simply: "We don't want heart attacks and strokes to happen. By being proactive, women have opportunities to lower their risks."

The goal isn't to worry teens about the chance of a heart attack, which are decades away for nearly all of them. It's that the teen years are when patterns get set, and it's much easier to keep good heart health than to get it back.— Dr. Amanda M. Perak, associate professor of pediatrics and preventive medicine, Northwestern University

Khan described the intellectual journey that led to the reports: researchers first noticed the pregnancy-heart disease link, then gathered evidence on menopause, then began hearing more about PMOS as a heart-health marker. In Khan's telling, "it became clear that there was a shared thread, and what we needed to do is tie it all together." The three papers published Monday are that attempt.

Why it matters — For the roughly half the population that is female, this framework means cardiovascular risk conversations should begin in the pediatrician's office — not the cardiologist's waiting room decades later — and every hormonal life event is now a recognized data point for heart health.
