Insights
Pulse pressure (PP), a marker for arterial stiffness and cardiovascular risk, showed correlations with inflammatory markers fibrinogen and erythrocyte sedimentation rate (ESR). However, these links weakened with age, but ESR remained significant with pulse pressure after adjusting for body mass index.
Area of Science:
- Cardiovascular Medicine
- Inflammation Research
- Epidemiology
Background:
- Pulse pressure (PP) is an independent predictor of cardiovascular risk, potentially causing arterial wall and endothelial lesions.
- Systemic inflammation is a key pathway in cardiovascular disease pathogenesis.
- Understanding the relationship between arterial stiffness markers and inflammation is crucial for cardiovascular health.
Purpose of the Study:
- To investigate the correlation between pulse pressure and common markers of systemic inflammation.
- To explore the influence of age and body mass index (BMI) on these correlations.
Main Methods:
- Study included 54 healthy premenopausal women.
- Measurements included anthropometrics, blood chemistry (fibrinogen, ESR, WBC), and blood pressure.
- Statistical analyses were performed to assess correlations, controlling for age and BMI.
Main Results:
- Fibrinogen levels were significantly higher in women with PP > 50 mmHg.
- Initial correlations found between PP and fibrinogen (P < 0.05) and ESR (P < 0.05).
- After controlling for age, correlations between PP and fibrinogen/ESR were not significant, but ESR remained significant with PP after controlling for BMI.
Conclusions:
- Findings suggest a relationship between pulse pressure and inflammatory markers like ESR and fibrinogen in healthy women.
- The influence of age on the PP-inflammation link is notable, diminishing the correlation.
- Body mass index may play a role in maintaining the association between ESR and pulse pressure.
Abstract:
Several epidemiological studies showed that pulse pressure (PP), as a marker of large arterial stiffness, is an independent predictor of cardiovascular risk. A high pulse pressure may induce lesions of the vessel walls and of the endothelium of the large arteries. Now, inflammation represents one of the most extensively studied pathways involved in the pathogenesis of cardiovascular disease. The aim of the present study was to evaluate if usual markers of systemic inflammation were correlated with pulse pressure. In fifty-four apparently healthy premenopausal women, without any known disease, we performed anthropometrical and blood chemistry measurements, together with the standard measurements of blood pressure. Mean values of fibrinogen are significantly more elevated in PP > 50 mmHg group than in PP < 50 mmHg group (364.79 +/- 71.07 vs. 329.31 +/- 57.81, P < 0.05). Fibrinogen was also significantly correlated with PP (r = 0.27, P < 0.05). However, after controlling for age the correlation between PP and fibrinogen was not significant (r = 0.18, P = NS). ESR was significantly correlated with PP (r = 0.31, P < 0.05) and systolic blood pressure (SBP) (r = 0.32, P < 0.05) but not with diastolic blood pressure (DBP). After controlling for age the correlation between PP and erythrocyte sedimentation rate (ESR) was not significant (r = 0.20, P = NS), but after controlling for body mass index (BMI) this correlation became significant (r = 0.28, P < 0.05). White blood cell (WBC) was not correlated with age, SBP, DBP, PP, age and BMI and the mean values of WBC were increased in the PP > 50 mmHg group, but not significantly (6637.93 +/- 1615.19 vs. 6416.67 +/- 1427.57, P = NS). In our study we found that ERS and fibrinogen values are related to pulse pressure values. Otherwise, blood pressure values, including pulse pressure, were correlated with the age of the subjects and the correlation between pulse pressure and inflammatory markers (ESR and fibrinogen) was not significant after controlling for age. After controlling for BMI, the correlation between ESR and PP remains significant.
