Insights
Growth Differentiation Factor-15 (GDF-15) levels in male coronary artery disease (CAD) patients correlate with coagulation markers. GDF-15 may indicate coagulation instability in CAD, particularly acute coronary syndrome (ACS).
Area of Science:
- Cardiovascular Medicine
- Biomarkers
- Hematology
Background:
- Growth Differentiation Factor-15 (GDF-15) is a novel biomarker for coronary artery disease (CAD).
- The role of GDF-15 in the hypercoagulable state of CAD is not well understood.
- This study investigated the relationship between GDF-15 and coagulation parameters in male Chinese CAD patients.
Purpose of the Study:
- To explore the association between serum GDF-15 levels and various coagulation parameters in male patients with CAD.
- To determine if GDF-15 can serve as a biomarker for coagulation status in CAD.
- To investigate GDF-15's role in different CAD subgroups, including acute myocardial infarction (AMI) and stable angina (SA).
Main Methods:
- A cohort of 892 subjects (592 with CAD, 300 controls) was analyzed.
- Serum GDF-15, blood cell counts, lipids, glucose, and coagulation parameters were measured.
- Statistical analyses included Kruskal-Wallis, ANOVA, and univariate/multivariate linear regression.
Main Results:
- GDF-15 levels were significantly higher in CAD patients (AMI and SA) compared to controls.
- GDF-15 positively correlated with activated partial thromboplastin time (APTT) and inversely with antithrombin III (AT3) in CAD patients.
- In AMI patients, GDF-15 was associated with APTT and monocyte count; in SA patients, it was inversely associated with AT3.
Conclusions:
- Elevated GDF-15 in male CAD patients is linked to altered coagulation parameters.
- GDF-15 may act as a compensatory marker for coagulation instability in CAD.
- GDF-15 shows potential as a biomarker for assessing coagulation status in CAD, especially in ACS.
Background:
Growth differentiation factor-15 (GDF-15) has emerged as a novel biomarker for coronary artery disease (CAD). Although the hypercoagulable state is recognized as a biological mechanism that triggers cardiac events in CAD, the relationship between GDF-15 and coagulation parameters in patients with CAD remains unclear. Thus, this study aimed to investigate the potential relationship between GDF-15 and coagulation parameters in male Chinese patients with CAD.
Methods:
In total, 892 subjects were enrolled between January 2020 and December 2020, including 592 with CAD and 300 controls. The serum levels of GDF-15, blood cell count, glucose, serum lipids, and coagulation parameters were measured. Kruskal-Wallis or one-way ANOVA with post hoc tests (Holm-Sidak and Dunn's tests), as well as univariate/multivariate linear regression analyses, were used to determine the correlation between GDF-15 and coagulation parameters in male patients with CAD.
Results:
Compared to controls, patients with acute myocardial infarction (AMI) and stable angina (SA) showed significantly higher levels of GDF-15 (p < 0.05). Multivariate linear regression revealed that GDF-15 levels were positively associated with activated partial thromboplastin time (APTT) in patients with CAD (β = 0.109, p = 0.024), and inversely associated with antithrombin III (AT3) (β = -0.113, p = 0.028) in an adjusted multivariate regression model. Meanwhile, in a multivariate regression model adjusted for other variables, the GDF-15 levels in patients with SA were inversely associated with AT3 (β = -0.191, p = 0.036). After adjusting for confounders, the GDF-15 levels were positively associated with APTT (β = 0.174, p = 0.002) and inversely associated with monocyte count (β = -0.159, p = 0.025) in patients with AMI.
Conclusions:
Elevated levels of GDF-15 in male CAD patients are associated with altered coagulation parameters, suggesting that GDF-15 may serve as a compensatory marker for coagulation parameter instability. These results underscore the potential clinical value of GDF-15 as a novel biomarker for assessing the coagulation status in patients with CAD, especially in the acute coronary syndrome (ACS) subgroup.
