Does PCOS raise heart and artery disease risk in young women?
Yes. In a study of 413,450 US women, those with PCOS had about 4.4 times the risk of heart and artery disease of women without the condition. The gap held after the researchers accounted for traditional heart risk factors. The women were young, with an average age of 31 at the start. The study used US insurance claims from 2000 to 2022.
The condition has just been renamed. What most people know as polycystic ovary syndrome (PCOS) is now called polyendocrine metabolic ovarian syndrome, or PMOS. The new name says something important about the disease. It is not only an ovary problem. It involves several hormone systems and the way the body handles sugar and fat, which is exactly why the heart keeps showing up in the research.
What the data show
Researchers led by the University of Rochester compared 413,450 women diagnosed with PMOS against 2,067,250 women without it, matched by age. All were 18 to 50 years old and had no artery disease at the start. The women with PMOS already had more traditional heart risk factors at the start. After the researchers adjusted for those factors, the PMOS group’s risk of atherosclerotic cardiovascular disease, meaning cholesterol buildup in the arteries, was 4.4 times higher. That is roughly a 340 percent increase.
What counted as artery disease
The study counted three kinds of events together: coronary artery disease (the arteries of the heart, which cause heart attacks), cerebrovascular disease (the arteries of the brain, which cause strokes and warning strokes), and peripheral artery disease, which is clogged arteries in the legs. This is not one narrow problem in one organ. It is artery disease that can show up anywhere in the circulatory system.
Dr. Kumar’s Take
The age matters most here. These women started out at an average age of 31. Heart risk is usually treated as a conversation for someone’s fifties, so a fourfold difference showing up in a group this young is a strong argument for earlier screening. Just as important, the higher risk held after the researchers accounted for traditional heart risk factors. So a young woman with PMOS should not assume her arteries are fine just because her usual numbers look good.
Beyond the usual risk factors
Women with PMOS often carry the classic heart risks. They are more likely to have extra weight, insulin resistance, high blood pressure, and abnormal cholesterol. The obvious assumption is that those conditions explain the heart disease. This study suggests they may not be the whole story. After the researchers adjusted for traditional heart risk factors, the risk was still 4.4 times higher. The study does not show why.
Limits worth knowing
This is insurance claims data covering 2000 to 2022, not a controlled trial. Claims records show what was billed, not what a doctor examined, so some women with PMOS were almost certainly missed and coded as healthy. Because the condition is often diagnosed late, the women who did get diagnosed may have had more severe disease and more medical attention overall. A study like this can show a strong link, but it cannot prove that PMOS itself causes the artery damage. It also cannot show whether treating the syndrome earlier lowers heart risk.
Practical takeaways
- If you have been diagnosed with PCOS or PMOS, ask your doctor for a cardiovascular risk assessment now rather than waiting until your forties, including blood pressure, a full cholesterol panel, and a blood sugar or A1c test.
- Do not let normal routine numbers reassure you completely, since this study found extra risk that persisted even after adjusting for traditional heart risk factors.
- Learn the warning signs of the artery problems this study tracked, including leg pain when walking and brief episodes of weakness, numbness, or slurred speech that resolve on their own.
- Bring up the condition by name at general medical visits, because a diagnosis made years ago in a gynecology office may not be in front of the doctor checking your heart.

FAQs
Why was polycystic ovary syndrome renamed?
The old name pointed at the ovaries and at cysts, and both parts were misleading. The fluid-filled sacs seen on ultrasound are not true cysts, and plenty of women meet the diagnostic criteria without them. Meanwhile the condition reliably involves insulin, androgens, and other hormone systems throughout the body. The new name, polyendocrine metabolic ovarian syndrome, describes a whole-body hormone and metabolic condition instead of a single organ finding.
How many women does this affect?
Roughly 1 in 10 women of reproductive age have the condition, which makes it one of the most common hormone disorders in women. That prevalence is what turns this study’s risk numbers into a public health issue rather than a niche finding. Many of those women were diagnosed during fertility workups or after irregular periods, then never followed for heart risk afterward. If you were told years ago that you had PCOS and the conversation ended there, this study is a reason to reopen it.
Does a PMOS diagnosis mean heart disease is inevitable?
No. A 4.4 times higher risk is a strong signal about a group, not a prediction about any one person. The practical value of a number like this is that it justifies earlier screening and closer attention to the risks you can act on, including blood pressure, blood sugar, cholesterol, smoking, activity, and sleep. This study was not designed to test whether earlier treatment changes the outcome, so that remains an open question.
Should younger women with PMOS get heart imaging or just blood tests?
That decision belongs with your own physician, and this study does not answer it. What the results support is starting the risk conversation much earlier than usual, since the women here were tracked from an average age of 31. For most people, that conversation begins with the basics: blood pressure, cholesterol, blood sugar, family history, and symptoms. Advanced imaging is usually reserved for those whose basic numbers or symptoms suggest a higher likelihood of disease.
Bottom line
In this study of more than 413,000 women, those with polyendocrine metabolic ovarian syndrome were about 4.4 times more likely to develop atherosclerotic cardiovascular disease than women without it. The elevated risk held after adjusting for traditional heart risk factors. The study shows a link, not that the syndrome itself causes the artery disease. For a condition affecting about 1 in 10 women of reproductive age, that is a strong argument for treating a PMOS diagnosis as a cardiovascular one too, starting in a woman’s thirties rather than decades later.
