(Press-News.org) Women of childbearing age who had both ovaries removed, in a procedure called bilateral oophorectomy, were more likely to develop heart failure later in life, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).
Bilateral oophorectomy is often recommended to treat and, in some cases, prevent certain health issues, including endometriosis, pelvic inflammatory disease, heavy bleeding and ovarian cancer. The new study sheds light on the potential and unique role that this procedure might play in heightening cardiovascular risk given that it abruptly stops the production of estrogen and other hormones and, depending on timing, can induce early onset menopause, which researchers said may be distinct from other causes of early menopause.
“We know that sex hormones, including estrogen and progesterone levels, play a crucial role in cardiovascular risk. Our study shows that there is an association between removing both ovaries and future development of heart failure, in particular.” said Narathorn Kulthamrongsri, MD, a first-year internal medicine resident at the University of Hawaii in Honolulu. "We believe this may be due to early menopause. However, in this case, early menopause results from the planned surgical removal of the ovaries, which differs from other causes such as occult infections, autoimmune diseases or unexpected genetic disorders. Understanding this allows us to anticipate and manage potential complications, particularly cardiovascular disease."
The study uses data from 6,814 female patients who participated in the National Health and Nutrition Examination Survey (NHANES) between 2017 and 2023. The average age of women undergoing the procedure was 43.6 years and 57 years for heart failure diagnosis. The ages at oophorectomy and heart failure onset were self-reported.
Compared with women in the general population who have their ovaries, those who underwent a bilateral oophorectomy had a 1.5-fold increased risk of developing heart failure after adjusting for race, age, gender, diabetes, smoking status and high cholesterol. White women and those who had their ovaries removed at younger ages had an even higher, twofold increased risk of developing heart failure.
“The age at which a woman has her ovaries removed appears to [impact] her heart failure risk,” Kulthamrongsri said. "We found that as the age at which a woman has her ovaries removed goes up by one year, the development of heart failure happens about 0.6 years later."
According to researchers, their findings also underscore the need to integrate cardiovascular risk discussions and closer heart monitoring for women contemplating oophorectomy before natural menopause (defined as not having a period for one full year), which usually occurs at 51 years of age, on average.
“Women must do what is medically necessary in terms of oophorectomy, but our findings suggest they should have an informed discussion with their health care team about how to monitor their cardiovascular health and manage potential risk factors for heart failure, including adopting a healthy lifestyle as much as possible and perhaps asking about any potential role of hormone replacement therapy,” Kulthamrongsri said.
While some women may not have a choice in terms of when they undergo this procedure, for those who do, an informed discussion about the best timing based on their age and health is important to be able to discuss and weigh the potential added cardiovascular risks. This may be especially important for White women who appear to have a much higher risk of developing heart failure.
“This racial disparity is surprising, as previous research shows that Black individuals have a higher prevalence of worse outcomes in heart failure due to greater risks of hypertension, diabetes and obesity. In contrast, White individuals more often develop heart failure from ischemic heart disease and tend to have more lifestyle-related risk factors, such as smoking, poor diet and physical inactivity. This finding might be explained by the etiology of heart failure that develops in early surgical menopause, related to myocardial infarction or other etiologies in which sex hormones play a crucial role,” Kulthamrongsri said.
The study is limited in that it relied on self-reported data and the researchers were only able to look at lifelong risk of heart failure rather than being able to determine if oophorectomy was more likely to lead to heart failure within a certain period after the procedure.
However, Kulthamrongsri said the findings add to a growing body of evidence that early surgical menopause may have long-term cardiovascular consequences, particularly an increased risk of heart failure. This concern is especially relevant given the number of women who undergo oophorectomy procedures.
Additional studies should be done to validate these findings using larger, global datasets. Future research should also explore possible preventive solutions, including cardiovascular screening recommendations and the use of prophylactic heart medications.
Kulthamrongsri will present the study, “How Bilateral Ovarian Removal Could Be Related to Heart Failure: Insights from NHANES 2017-2020,” Sunday, March 30, 2025, at 9:00 a.m. CT / 14:00 UTC in South Hall.

The answer to your heart health may be on your wrist, a new study suggests. Researchers have developed a new way to assess cardiovascular health based on information routinely collected by smartwatches, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).
According to the findings, dividing the average daily heart rate by the number of steps taken per day provides a more reliable indicator of a person’s cardiovascular fitness compared with either heart rate or step count alone.
“The metric we developed looks at how the heart responds to exercise, rather than exercise itself,” said Zhanlin Chen, ...
Mammograms, with the help of artificial intelligence (AI) models, may reveal much more than cancer, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25). The findings highlight how these important cancer screening tools can also be used to assess the amount of calcium buildup in the arteries within breast tissue—an indicator of cardiovascular health.
The U.S. Centers for Disease Control and Prevention recommends that middle-aged and older women get a mammogram—an X-ray of the breast—to screen for breast cancer every one or two ...

Nearly 3 out of every 4 older Americans have experienced at least one extreme weather event in the last two years, a new University of Michigan poll finds. And living through such an event appears to make a big difference in how they view the potential impact of climate change on their health.
The new findings from the National Poll on Healthy Aging show that 59% of people aged 50 and over are concerned about how climate change could affect their health.
The percentage expressing concern was even higher among those who had recently lived through a weather ...
Complex materials such as organic semiconductors or the microporous metal-organic frameworks known as MOFs are already being used for numerous applications such as OLED displays, solar cells, gas storage and water extraction. Nevertheless, they still harbour a few secrets. One of these has so far been a detailed understanding of how they transport thermal energy. Egbert Zojer’s research team at the Institute of Solid State Physics at Graz University of Technology (TU Graz), in collaboration with colleagues from TU Vienna and the University of Cambridge, has now cracked this ...
Women with polycystic ovary syndrome (PCOS) find it harder to get pregnant, have more frequent miscarriages and have a higher risk of developing endometrial cancer. Now, in a new study published in Nature Medicine, Swedish researchers have shown that the uterine lining of these women differs in terms of both the composition of individual cells and gene expression. The results open the door to new drug treatments.
PCOS is the most common hormonal disorder affecting 11-13% of women of reproductive age. Women with the syndrome have difficulty getting pregnant and are at increased ...
As animals experience new things, the connections between neurons, called synapses, strengthen or weaken in response to events and the activity they cause in the brain. Neuroscientists believe that synaptic plasticity, as these changes are called, plays an important role in storing memories.
However, the rules governing when and how much synapses change are not well understood. The traditional view is that the more two neurons fire together, the stronger their connection becomes; when they fire separately, their connection weakens.

Scientists from the RIKEN Center for Emergent Matter Science (CEMS) and collaborators have discovered a groundbreaking way to control superconductivity—an essential phenomenon for developing more energy-efficient technologies and quantum computing—by simply twisting atomically thin layers within a layered device. By adjusting the twist angle, they were able to finely tune the “superconducting gap,” which plays a key role in the behavior of these materials. The research was published in Nature Physics.
The superconducting gap is the energy threshold required to break apart Cooper pairs—bound electron pairs that enable superconductivity at low temperatures. ...
New Haven, Conn. — Advances in the gene-editing technology known as CRISPR-Cas9 over the past 15 years have yielded important new insights into the roles that specific genes play in many diseases. But to date this technology — which allows scientists to use a “guide” RNA to modify DNA sequences and evaluate the effects — is able to target, delete, replace, or modify only single gene sequences with a single guide RNA and has limited ability to assess multiple genetic changes simultaneously.
Now, however, Yale scientists have developed a series of sophisticated mouse models using CRISPR (“clustered regularly ...
The American Gastroenterological Association (AGA) released a new clinical guideline making no recommendation — for or against — the use of computer-aided detection systems (CADe) in colonoscopy. A rigorous review of evidence showed that artificial intelligence-assisted technology helps identify colorectal polyps. However, its impact on preventing colorectal cancer — the third most common cancer worldwide — remains unclear.
Colonoscopy, performed more than 15 million times annually in the U.S., is an effective tool for detecting and preventing colorectal cancer. CADe systems have been shown to improve polyp detection ...
