Insights
Blood pressure variation, particularly systolic pressure fluctuations, is linked to carotid artery plaque. This finding highlights blood pressure variability as a key factor in atherosclerosis development.
Area of Science:
- Cardiovascular medicine
- Vascular biology
- Hypertension research
Context:
- Carotid artery plaque is a significant indicator of cardiovascular disease risk.
- Blood pressure variability is increasingly recognized as a crucial factor in cardiovascular health.
- Understanding the interplay between blood pressure patterns and atherosclerosis is vital for risk stratification.
Purpose:
- To examine the association between carotid artery plaque and blood pressure variability.
- To identify cardiovascular risk factors correlated with carotid artery plaque.
- To determine if blood pressure variation independently predicts carotid atherosclerosis.
Summary:
- A retrospective analysis of 408 hypertensive patients revealed a 55.3% prevalence of carotid artery plaque, increasing with age.
- Carotid plaque was associated with disease duration, blood sugar, total cholesterol, and LDL cholesterol.
- The prevalence of carotid plaque correlated positively with the coefficient of variation of 24-hour systolic blood pressure.
Impact:
- Carotid atherosclerosis is independently associated with blood pressure variability, especially systolic.
- This suggests that monitoring blood pressure fluctuations may improve cardiovascular risk assessment.
- Findings emphasize the importance of managing blood pressure variability in hypertensive patients to prevent atherosclerosis.
Objective:
To investigate the relationship of carotid artery plaque and blood pressure variation and cardiovascular risk factors.
Methods:
We retrospectively analyzed clinical data of in-patients treated in the department of hypertension between April 2009 and June 2010. Information on carotid ultrasonography and other clinical date were obtained from 408 patients. All patients were monitored by ambulatory blood pressure.
Results:
(1) Carotid artery determined in plaque was 55.3%, there was no differences between men and women. However, the carotid artery plague was associated positively with age. Increased age was associated with a significantly increased positive rate. (2) Cardiovascular risk factors and carotid artery plaque: carotid artery plaque was associated with duration of disease, fasting blood sugar, total cholesterol, and low density lipoprotein-cholesterol. (3) 24 h ambulatory blood pressure and carotid artery plaque: the prevalence of carotid artery plaque increased with increasing coefficient of systolic variation (P = 0.001). There was no correlation between the coefficient of diastolic variation and the prevalence (P = 0.644).(4) Multivariate regression analysis indicated that carotid artery plaque was associated with duration of hypertension, 24 h mean systolic blood pressure, and coefficient of variation of 24 h blood pressure (P < 0.05).
Conclusion:
Carotid atherosclerosis is independently associated with coefficient of variation of blood pressure, especially with coefficient of variation of systolic blood pressure.
