Metabolic polyendocrine ovarian syndrome linked to higher cardiovascular risk

Women diagnosed with metabolic polyendocrine ovarian syndrome, formerly known as polycystic ovary syndrome (PCOS), may face a significantly elevated risk of developing atherosclerotic cardiovascular disease, according to a recent U.S. analysis. The study, which examined data from 413,450 women aged 18 to 50, did not establish a direct causal link but revealed a substantial correlation.

Researchers compared two groups of women, those with and without the syndrome, finding that the risk of cardiovascular events was 4.4 times higher in the group with PCOS. This heightened risk remained evident even when factors such as obesity, high blood pressure, high cholesterol, and diabetes were taken into account. The findings suggest that biological mechanisms intrinsically linked to the syndrome, beyond traditional risk factors, could be contributing to heart disease.

"Our findings, which show that women with this syndrome presented a higher incidence of atherosclerotic cardiovascular events, underscore the need to educate health professionals and raise patient awareness about cardiovascular disease risk to improve the implementation of early preventive interventions," the study's authors concluded. They stressed that early detection must be coupled with healthy eating habits and regular physical activity to reduce long-term risks.

While the study provides robust evidence, its reliance on administrative data from 2000 to 2022 has limitations, including potential classification errors and incomplete clinical details. Pluvio Coronado, a professor at the Complutense University of Madrid, acknowledged the study's significant contribution in reinforcing previously documented links between PCOS and increased cardiovascular risk, particularly through its association with diabetes, obesity, and hormonal imbalances. He noted that while the evidence is stronger, the study design does not prove causality, though he believes residual risk is likely due to the syndrome's inherent biological factors.
