Berlin, Germany – February 23, 2026 – A new study published today in Circulation: Cardiovascular Imaging challenges conventional wisdom about heart disease risk in women, finding that they may experience heart attacks and chest pain with significantly less artery-clogging plaque than men. The research, involving over 4,200 adults, suggests a potentially faster progression of heart disease risk for women, particularly after menopause. This finding underscores the demand for a reevaluation of current diagnostic and preventative strategies for cardiovascular health in women.
Heart disease remains the leading cause of death for both men and women globally, according to the American Heart Association’s 2026 Heart Disease and Stroke Statistics. Previous research has consistently shown that men tend to accumulate more plaque in their arteries than women. However, this new study indicates that the *amount* of plaque may not be as critical a factor in assessing risk for women as it is for men. The study focused on individuals experiencing stable chest pain but without a prior history of coronary artery disease, utilizing coronary computed tomography angiography (CCTA) – X-ray imaging of the heart and blood vessels – to assess plaque levels.
Plaque Burden and Cardiovascular Events: A Gender Disparity
The study revealed a clear difference in plaque prevalence between genders. Fewer women (55%) had plaque in their coronary arteries compared to men (75%). Women exhibited a lower volume of artery plaque, with a median of 78 mm3, compared to 156 mm3 in men. Despite these lower levels, the study found no significant difference in the rates of death from any cause, non-fatal heart attack, or hospitalization for chest pain between women and men (2.3% of women vs. 3.4% of men). This suggests that women may be experiencing cardiovascular events despite having what would be considered a lower risk profile based on traditional plaque assessment.
“These findings are significant due to the fact that they challenge the traditional approach to assessing heart disease risk, which heavily relies on the amount of plaque present,” explains Dr. Philipp Erne, lead author of the study and a cardiologist at University Heart Center Zurich, as reported by MSN. “women may be more vulnerable to the effects of plaque, or that other factors are at play that contribute to their risk.”
The Role of Menopause and Hormonal Changes
The research also highlighted a potential link between menopause and increased cardiovascular risk in women. The study indicated that the risk of heart attack and chest pain in women appeared to increase more rapidly after menopause than in men. This observation aligns with existing knowledge about the protective effects of estrogen on cardiovascular health. Estrogen is known to positively influence cholesterol levels and blood vessel function. The decline in estrogen levels during menopause is thought to contribute to an increased risk of heart disease.
While the exact mechanisms underlying this gender disparity remain unclear, researchers hypothesize that factors beyond plaque burden, such as microvascular disease (affecting the small blood vessels of the heart), inflammation, and hormonal changes, may play a more significant role in women’s cardiovascular health. Microvascular disease, often difficult to detect with traditional imaging techniques, can impair blood flow to the heart muscle and lead to chest pain and other symptoms.
Implications for Diagnosis and Treatment
The findings of this study have important implications for how heart disease is diagnosed and treated in women. Current guidelines often focus on assessing plaque burden as a primary indicator of risk. However, this research suggests that a more nuanced approach is needed, one that considers the unique physiological characteristics and risk factors of women.
“We need to move beyond simply counting plaque and start looking at other factors that may be contributing to cardiovascular risk in women,” says Dr. Robert J. Gropler, Editor-in-Chief of Circulation: Cardiovascular Imaging. “This may involve utilizing more advanced imaging techniques to assess microvascular function, evaluating inflammatory markers, and taking into account hormonal status.”
What Does This Indicate for Women’s Health?
This study reinforces the importance of proactive cardiovascular health management for women, particularly as they approach and navigate menopause. Lifestyle modifications, such as maintaining a healthy diet, engaging in regular physical activity, managing stress, and avoiding smoking, remain crucial for reducing heart disease risk. However, women should also discuss their individual risk factors with their healthcare providers and consider whether additional screening or preventative measures are appropriate.
The American Heart Association recommends that all adults over the age of 20 have their blood pressure checked regularly and that they undergo cholesterol screening every four to six years, or more frequently if they have risk factors for heart disease. Women should also be aware of the symptoms of heart attack, which can differ from those experienced by men and may include shortness of breath, nausea, and back or jaw pain, in addition to the more typical chest discomfort.
Future Research Directions
Researchers are continuing to investigate the underlying mechanisms driving the gender disparity in heart disease risk. Future studies will focus on exploring the role of microvascular disease, inflammation, and hormonal factors in greater detail. They will also aim to develop more accurate and personalized risk assessment tools for women, taking into account their unique physiological characteristics and risk profiles.
The study authors emphasize the need for larger, more diverse studies to confirm these findings and to further elucidate the complex interplay of factors that contribute to cardiovascular disease in women. A better understanding of these factors will lead to more effective strategies for preventing and treating heart disease in this vulnerable population.
Key Takeaways
- Women may experience heart attacks and chest pain with less artery-clogging plaque than men.
- The risk of heart events in women appears to increase more rapidly after menopause.
- Current diagnostic approaches may underestimate cardiovascular risk in women.
- A more nuanced approach to risk assessment, considering factors beyond plaque burden, is needed.
The findings from this study, published in Circulation: Cardiovascular Imaging, represent a crucial step forward in understanding the complexities of heart disease in women. Further research and a shift in clinical practice are essential to ensure that women receive the appropriate care and support to protect their cardiovascular health. The American Heart Association will continue to update its guidelines as new research emerges. Readers are encouraged to discuss their individual risk factors with their healthcare providers.
