Insights
High tissue factor pathway inhibitor (TFPI) activity is linked to increased mortality risk. Smoking positively influences TFPI levels, while diabetes and obesity are negatively associated, suggesting complex interactions in cardiovascular disease.
Area of Science:
- Cardiovascular Medicine
- Hemostasis and Thrombosis
- Epidemiology
Background:
- Tissue factor pathway inhibitor (TFPI) is a key regulator of the extrinsic coagulation cascade.
- Understanding TFPI's role in cardiovascular disease (CVD) and mortality is crucial for risk assessment.
Purpose of the Study:
- To identify cardiovascular determinants of total TFPI activity.
- To investigate the association between total TFPI activity and CVD and overall mortality.
Main Methods:
- Assessed total TFPI activity in 5,000 participants from the Gutenberg Health Study.
- Employed multivariable linear and Cox regression analyses to determine associations.
Main Results:
- Smoking was a positive determinant of TFPI activity; diabetes and obesity were negative determinants.
- Higher TFPI activity (above 97.5th percentile) was associated with a 2.58-fold increased mortality risk.
- TFPI activity showed a strong positive association with low-density lipoprotein levels.
Conclusions:
- Elevated TFPI activity in a population-based cohort correlates with increased mortality.
- Observed associations suggest TFPI may reflect endothelial activation and interact with obesity and coronary artery disease mechanisms.
Objective:
Tissue factor pathway inhibitor (TFPI) is a potent anticoagulant protein in the extrinsic coagulation pathway. In the present study, we aim to identify the cardiovascular determinants for total TFPI activity and its association with cardiovascular disease (CVD) and total mortality.
Methods:
Total TFPI activity was assessed in a selection of the population-based Gutenberg Health Study (n = 5,000). Statistical analysis was performed to identify the determinants for total TFPI activity as well as the associations with CVD and mortality.
Results:
Multivariable linear regression analysis identified smoking (β 0.095 [0.054-0.136]) as a positive determinant for total TFPI activity, while diabetes (β -0.072 [-0.134 to -0.009]), obesity (β -0.063 [-0.101 to -0.024]), and history of coronary artery disease (CAD) were negatively associated with total TFPI activity, independent of age, sex, and the remaining cardiovascular risk factors. After adjustment for lipoprotein levels, the association between total TFPI activity levels and obesity and CAD was lost. The analysis additionally revealed a strong positive association between total TFPI activity levels and low-density lipoprotein (β 0.221 [0.204-0.237]). The Cox regression models revealed that a higher total TFPI activity, above 97.5th percentile of the reference group, was associated with an increased mortality risk (hazard ratio = 2.58 [95% confidence interval: 1.49-4.47]), independent of age, sex, and cardiovascular risk profile.
Conclusion:
In the Gutenberg Health Study population-based cohort, the highest percentage of total TFPI correlated with an increased mortality risk. While elevated TFPI may reflect endothelial cell activation, the associations between total TFPI activity and obesity and CAD, points to additional mechanistic interactions.
