Insights
Complement 1 inhibitor, an anti-inflammatory protein, positively correlates with arterial stiffness. This finding suggests C1 inhibitor may play a role in the development of arterial stiffness, independent of traditional risk factors.
Area of Science:
- Cardiovascular Medicine
- Immunology
- Biochemistry
Background:
- Complement 1 (C1) inhibitor is recognized for its anti-inflammatory properties.
- Arterial stiffness, measured by brachial-ankle pulse wave velocity (baPWV), is a significant cardiovascular risk indicator.
- The relationship between C1 inhibitor levels and arterial stiffness requires further elucidation.
Purpose of the Study:
- To investigate the association between C1 inhibitor levels and arterial stiffness (baPWV).
- To determine if C1 inhibitor is an independent predictor of arterial stiffness.
- To explore the role of inflammation in the relationship between C1 inhibitor and arterial stiffness.
Main Methods:
- A cohort of 100 subjects was enrolled.
- Data collected included baPWV, demographics, medical history, BMI, and various blood markers.
- Pearson correlation and multiple regression analyses were employed to assess relationships.
Main Results:
- A significant positive correlation was observed between C1 inhibitor levels and baPWV (P<0.001).
- Multiple regression analysis identified C1 inhibitor as a significant predictor of baPWV, alongside age, gender, hypertension, and BMI.
- These findings were independent of other measured inflammatory markers.
Conclusions:
- C1 inhibitor is significantly associated with arterial stiffness.
- C1 inhibitor may serve as an independent predictor of arterial stiffness.
- The association suggests a potential role for C1 inhibitor in the inflammatory pathways contributing to arterial stiffness.
Abstract:
Complement 1 (C1) inhibitor is an acute phase protein with anti-inflammatory properties. The aim of the present study was to elucidate the relationship between brachial ankle pulse wave velocity (baPWV), the parameter of arterial stiffness, and C1 inhibitor. One hundred subjects were randomly enrolled in this study. Data about baPWV, age, gender, hypertension, smoking, and body mass index (BMI) were measured. Blood tests for total cholesterol, low density lipoprotein, high density lipoprotein, triglycerides, hemoglobin A1c, erythrocyte sedimentation rate, C-reactive protein, complement 3, and C1 inhibitor were performed. Based on the Pearson correlation, the C1 inhibitor showed a positive relation to the baPWV (P<0.001). Multiple regression analysis revealed the significant predictors of baPWV were not only the conventional risk factors of arteriosclerosis and/or atherosclerosis, such as age (P<0.001), gender (P<0.001), hypertension (P<0.001), and BMI (P=0.006), but also the acute phase protein, C1 inhibitor (P=0.025). In conclusion, C1 inhibitor is associated with arterial stiffness through its association with increased inflammation.
