Insights
Obesity is linked to reduced plasma fibrinolytic activity, likely due to increased plasminogen activator inhibitor (PAI) levels. This may contribute to a thrombophilic state in obese individuals.
Area of Science:
- Biochemistry
- Physiology
- Medical Research
Background:
- Obesity is a growing global health concern.
- Impaired fibrinolytic activity is associated with thrombotic events.
- The relationship between obesity, fibrinolysis, and related markers requires further investigation.
Purpose of the Study:
- To investigate the correlation between Body Mass Index (BMI) and fibrinolytic system markers.
- To explore the potential link between obesity, plasminogen activator inhibitor (PAI), C-peptide, and fibrinolytic activity.
Main Methods:
- Cross-sectional study involving 71 healthy adults (aged 20-60).
- Measurements included Body Mass Index (BMI), plasminogen activator inhibitor (PAI) activity, C-peptide levels, and plasma fibrinolytic activity.
- Statistical analysis to determine correlations between variables.
Main Results:
- Significant negative correlation found between BMI and plasma fibrinolytic activity (r = -0.382, p < 0.005).
- Significant positive correlations observed between BMI and PAI (r = 0.353, p < 0.005) and between BMI and C-peptide (r = 0.694, p < 0.001).
- A positive correlation was also found between PAI and C-peptide (r = 0.404, p < 0.02).
Conclusions:
- Obesity is associated with decreased plasma fibrinolytic activity, potentially mediated by elevated PAI levels.
- Impaired fibrinolysis in obesity, possibly linked to hyperinsulinemia (indicated by C-peptide), may promote a thrombophilic state.
- These findings highlight a potential mechanism linking obesity to increased thrombotic risk.
Abstract:
Seventy-one healthy subjects, aged 20 to 60, 19 males and 52 females, body mass index (BMI) 19 to 40, were enrolled in the study. None of them were smokers, or affected by hyperlipidemia, arterial hypertension or impaired glucose tolerance. We measured plasminogen activators inhibitor (PAI) activity, C-peptide levels, plasma fibrinolytic activity. We found a correlation between BMI and plasma fibrinolytic activity (r = -0.382, p less than 0.005), between BMI and PAI (r = 0.353, p less than 0.005), between BMI and C-peptide (r = 0.694, p less than 0.001) and between PAI and C-peptide (r = 0.404, p less than 0.02). Our data show a correlation between obesity and low fibrinolytic activity, probably due to high PAI levels. In obesity impaired fibrinolytic activity, maybe linked to hyperinsulinemia, could induce thrombophilic state.
