Women Face Higher Heart Risks With Less Plaque Than Men, Study Finds

Women develop heart problems at lower levels of artery plaque than men, new research suggests. Even with less plaque buildup, their risk of heart attacks and chest pain rises sharply—often earlier and more severely than in male patients. This challenges the assumption that women face fewer cardiovascular dangers due to lower plaque volumes overall.

A recent study found that women's cardiovascular risk begins climbing at a 20% plaque burden, compared to 28% in men. While men typically accumulate more plaque before facing serious issues, women experience major cardiac events just as frequently. The data also showed that moderate plaque increases trigger a disproportionate spike in risk for women, particularly after menopause.

During follow-up, 2.3% of women suffered fatal or non-fatal heart attacks, died from any cause, or were hospitalised for chest pain—slightly lower than the 3.4% of men. Yet despite this smaller percentage, women's risk escalated more steeply as plaque levels rose. Researchers warn that standard risk assessments may underestimate the danger for female patients.

Cardiovascular disease remains a leading cause of death for women, accounting for 433,254 fatalities in the U.S. in 2026 alone. Biological differences between men and women play a key role in how plaque affects heart health, though further details on study participants and broader comparisons were not provided.

The findings highlight a critical gap in how heart disease risk is evaluated in women. Current guidelines may need revising to account for the faster, more severe impact of plaque in female patients. Without adjustments, women could continue facing undetected risks—even when their plaque levels seem relatively low.
