Insights
Sex differences in biomarker concentrations for acute coronary syndromes (ACS) and heart failure (HF) exist, but their clinical impact on diagnosis and prognosis in men versus women requires further investigation.
Area of Science:
- Cardiology
- Biomarker Research
- Sex-Based Medicine
Background:
- Sex-based variations are observed in biomarker concentrations for acute coronary syndromes (ACS) and heart failure (HF).
- Limited research has compared the diagnostic and prognostic value of these biomarkers between men and women.
- Biomarkers are crucial for clinical decisions in ACS and HF patient care.
Purpose of the Study:
- To review studies on sex differences in biomarker concentrations in ACS and HF.
- To examine comparative studies on the diagnostic and prognostic utility of biomarkers in men versus women.
- To discuss the clinical implications of potential sex-based differences in biomarker reference limits.
Main Methods:
- Mini-review of published literature.
- Analysis of studies comparing biomarker concentrations between sexes in ACS and HF.
- Evaluation of studies comparing biomarker utility for diagnosis and risk stratification in men versus women.
Main Results:
- Some studies indicate differences in biomarker concentration distributions between men and women.
- The clinical significance of these observed sex-based differences in biomarker levels is not yet clear.
- Potential sex-specific differences in the pathophysiology of ACS and HF may influence biomarker utility.
Conclusions:
- While biomarker concentration distributions may differ by sex, their clinical implications remain uncertain.
- Further research is necessary to fully understand the diagnostic and prognostic utility of biomarkers in men versus women.
- Investigating sex-specific pathophysiological differences is key to evaluating biomarker performance.
Background:
Sex-based differences exist in the circulating concentrations of certain novel and established biomarkers in patients with acute coronary syndromes (ACS) and heart failure (HF). However, to date, few studies have compared the diagnostic and prognostic utility of these markers in men vs women.
Content:
This mini-review contains a discussion of the published reports of studies that have explored whether differences in biomarker concentrations exist between men and women with ACS or HF. It also examines those studies that have compared the utility of biomarkers for diagnosis or risk stratification in women vs men. Because biomarkers are often used to make therapeutic and triage decisions in patient care, the potential clinical implications for any observed differences in biomarker reference limits for men and women is discussed.
Summary:
Although the concentration distributions may differ between men and women for certain biomarkers in clinical use, the clinical implications of these observations remain unclear. Because elements of the pathophysiology of ACS and HF may differ between the sexes, further research is needed to better evaluate the diagnostic and prognostic utility of biomarkers in men vs women.
