New Study Links PMOS to Higher Risk of Heart Disease
For decades, the condition now known as polyendocrine metabolic ovarian syndrome (PMOS), formerly called polycystic ovary syndrome (PCOS), has largely been viewed through the lens of reproductive health. Irregular periods, fertility challenges, and hormone imbalances have long defined the conversation around the disorder, despite its well-established links to metabolic conditions such as insulin resistance and type 2 diabetes. A major new study now suggests the condition may also carry a much greater cardiovascular burden than previously understood, strengthening calls for doctors to treat PMOS as a lifelong health condition rather than one primarily associated with fertility.
Researchers from the University of Pennsylvania and the University of Rochester found that women with PMOS face a significantly higher risk of developing atherosclerotic cardiovascular disease, including heart attacks and strokes, even after accounting for many of the traditional risk factors that contribute to heart disease. Published in The Lancet Obstetrics, Gynecology & Women's Health, the research is the largest study to date examining the connection between PMOS and cardiovascular disease and arrives just months after an international coalition of medical organizations officially adopted the new name to better reflect the condition's endocrine and metabolic nature. Together, the findings mark an important shift in how one of the world's most common hormonal disorders is understood and managed.

A Larger Heart Risk Than Previously Understood
To investigate the long-term impact of PMOS on cardiovascular health, researchers analyzed health records from more than 2 million women across the United States, including over 413,000 women diagnosed with the condition. While previous studies had hinted at an association between PMOS and heart disease, many were too small to determine whether the syndrome itself contributed to cardiovascular risk or whether the increased risk was largely explained by obesity, diabetes, high blood pressure, and other related conditions.
The results suggest the syndrome plays a more direct role than previously believed. Even after adjusting for traditional cardiovascular risk factors, women with PMOS remained significantly more likely to experience serious cardiovascular events. The study found they were approximately 2.5 times more likely to suffer a heart attack or stroke, more than three times more likely to experience a transient ischemic attack, commonly known as a mini-stroke, and nearly four times more likely to develop peripheral artery disease compared with women who did not have the condition. Those findings indicate that the hormonal, inflammatory, and metabolic changes associated with PMOS may contribute to cardiovascular disease independently of other well-known risks.
A Longstanding Blind Spot in Women's Health
Beyond its medical findings, the study has reignited discussion about a longstanding issue in healthcare: the historical underrepresentation of women's health in medical research. For much of modern medical history, women were routinely excluded from clinical trials because hormonal fluctuations were considered too difficult to account for. As a result, many diseases, including cardiovascular disease, were studied primarily in men, leaving important questions about how conditions affect women unanswered for decades.
Although research practices have changed significantly, experts say the legacy of those gaps can still be seen today. PMOS is a clear example. Despite affecting an estimated one in eight women worldwide, the condition has often been viewed primarily as a fertility disorder, even though it is associated with a wide range of long-term health complications, including metabolic syndrome, type 2 diabetes, endometrial cancer, and now an increasingly well-documented risk of cardiovascular disease. Researchers hope both the recent name change and studies like this one will encourage earlier diagnosis, greater awareness, and more comprehensive care throughout a patient's lifetime.
Why Earlier Screening Could Make a Difference
Heart disease remains the leading cause of death among women worldwide, making the study's findings particularly significant. The researchers stress that the results should not be interpreted to mean every woman with PMOS will eventually develop cardiovascular disease. Instead, they argue that the condition should become a routine part of cardiovascular risk assessments, prompting healthcare providers to monitor blood pressure, cholesterol, blood sugar, and other indicators much earlier than has traditionally been the case.
Earlier screening can help identify risk factors before they progress into more serious disease, giving patients the opportunity to make lifestyle changes or begin treatment sooner when appropriate. Regular exercise, maintaining a healthy weight, eating a balanced diet, avoiding smoking, and managing blood pressure and cholesterol remain among the most effective ways to reduce long-term cardiovascular risk. For women living with PMOS, the new findings suggest that those conversations should begin well before symptoms of heart disease ever appear.
As scientists continue to uncover the far-reaching effects of PMOS, the condition is increasingly being recognized as far more than a reproductive disorder. The latest findings add to growing evidence that hormonal, metabolic, and cardiovascular health are closely interconnected, reinforcing the need for earlier diagnosis, broader screening, and a more holistic approach to women's healthcare. For millions of women, that shift in understanding could make a meaningful difference long before heart disease develops.
