Recent clinical data suggests that plaque burden in women acts as a primary predictor for major adverse cardiovascular events, often at lower levels than previously suspected. Although women typically exhibit lower absolute plaque volumes compared to men, they do not necessarily possess a lower risk of heart attack. Consequently, medical professionals in India must reconsider how they interpret coronary imaging to avoid underestimating risk in female patients.
Why Plaque Burden in Women Requires Sex-Specific Thresholds
Because women generally have smaller coronary arteries, even minor plaque accumulation can significantly impact blood flow. Research published in Circulation: Cardiovascular Imaging indicates that a total plaque burden of just 20 per cent in women signals an elevated risk of cardiac events. In comparison, men only reach a similar risk level at approximately 28 per cent. Therefore, applying the same diagnostic thresholds to both sexes likely leads to delayed diagnosis and treatment for many women.

Accelerated Risk Trajectories in Female Patients
The study further highlights that risk increases more steeply at lower levels of plaque for women. While men often require larger amounts of plaque to show increased risk, the female heart appears more sensitive to moderate increases. Furthermore, Indian cardiologists note that women in the region often present with earlier-onset heart disease. This trend underscores the necessity of adopting tailored approaches for risk stratification. By recognizing these differences, clinicians can provide more accurate and personalized care.

Frequently Asked Questions
Q1: Why do women have similar cardiovascular event rates despite having less plaque?
Women possess smaller coronary arteries. As a result, even lower volumes of plaque result in a similar total plaque burden relative to the vessel size, leading to equivalent risk levels.
Q2: What is the specific risk threshold for total plaque burden in women?
Evidence suggests that cardiovascular risk becomes elevated at a 20 per cent total plaque burden in women, whereas the risk for men typically emerges at 28 per cent.
