Hypothesis
Can serum Lp-PLA2 levels and the PLA2G7 gene polymorphism (rs1805017) help predict coronary artery disease risk and severity?
Conclusion
Elevated serum Lp-PLA2 levels and homozygosity of the rs1805017 variant are significantly associated with increased risk and severity of coronary artery disease.
Supporting Evidence
- Elevated serum Lp-PLA2 levels were significantly associated with coronary artery disease.
- Homozygosity of the rs1805017 variant was identified as a key risk predictor for CAD.
- ROC analysis showed Lp-PLA2 had excellent diagnostic ability with an AUC of 0.935.
- Significant correlations were found between Lp-PLA2 levels and traditional cardiovascular risk factors.
- 25% of CAD patients were young men under 45 years, indicating early onset risk.
Takeaway
This study found that a specific gene variant and high levels of a certain enzyme in the blood can help doctors figure out who is at risk for heart problems.
Methodology
Cross-sectional, case-control study with 125 subjects, including 75 CAD cases and 50 controls, using serum biomarker analysis and genotyping.
Limitations
The study's cross-sectional design and single-center data collection limit the generalizability of the findings.
Participant Demographics
Participants included 125 subjects from a South Indian population, with 25% being young men under 45 years.
