To highlight the critical need for sex-specific biomarkers in cardiovascular risk prediction for women, addressing the unique biological and clinical factors that influence their cardiovascular health.
Key Findings:
LDL cholesterol (LDL-C) showed no prognostic value in the studied high-risk population, raising questions about its role in women.
Remnant cholesterol (RC) predicted major adverse cardiovascular events (MACE) in both sexes, highlighting its potential as a universal marker.
ApoA-1 and triglyceride/HDL-cholesterol ratio were significant predictors only in women, indicating the need for gender-specific assessments.
CERT1 and CERT2 scores were predictive only in men, suggesting a gap in understanding their applicability to women.
Interpretation:
The lack of predictive value for LDL-C may reflect the population context rather than LDL biology, emphasizing the urgent need for alternative biomarkers tailored to women's cardiovascular health.
Limitations:
The study population was predominantly elderly, high-risk, and statin-treated, which may limit the generalizability of the findings.
Key biomarkers like Lp(a) and non-HDL-C were not measured, potentially overlooking critical risk factors.
Potential calibration bias due to male-dominant derivation and validation cohorts may weaken the predictive performance for women.
Conclusion:
ApoB or non-HDL-C should complement LDL-C in assessing cardiovascular risk in women, reinforcing the need for updated clinical guidelines.
