Insights
Cardio-ankle vascular index (CAVI), a measure of aortic stiffness, is independently associated with left ventricular (LV) diastolic dysfunction in patients with preserved systolic function. Higher CAVI levels indicate increased risk for LV diastolic dysfunction.
Area of Science:
- Cardiovascular Medicine
- Vascular Biology
- Echocardiography
Background:
- Pulse wave velocity is a common index for aortic stiffness.
- Cardio-ankle vascular index (CAVI) measures aortic stiffness independently of blood pressure.
- Left ventricular (LV) diastolic dysfunction affects heart function.
Purpose of the Study:
- To analyze the relationship between CAVI and LV diastolic dysfunction.
- To investigate CAVI as a potential biomarker for diastolic dysfunction.
- To assess CAVI in patients with preserved systolic function.
Main Methods:
- 119 patients referred for echocardiography were studied.
- Patients with reduced systolic function were excluded.
- CAVI was measured, and patients were categorized by LV diastolic function status.
Main Results:
- CAVI was significantly higher in patients with reduced LV diastolic function.
- CAVI was independently associated with diastolic function parameters (peak early diastolic velocity/peak atrial diastolic velocity ratio, left atrial diameter).
- Highest CAVI quartile showed increased odds for LV diastolic dysfunction.
Conclusions:
- Increased CAVI is independently associated with LV diastolic dysfunction.
- CAVI may serve as a valuable indicator of diastolic dysfunction in patients with preserved systolic function.
- This finding highlights the link between aortic stiffness and diastolic heart abnormalities.
Aim:
Pulse wave velocity has been used as an index of aortic stiffness. Recently, the cardio-ankle vascular index (CAVI), which reflects the stiffness of the aorta independently of blood pressure, has been developed. In this study, we analyzed the relationship between CAVI and left ventricular (LV) diastolic dysfunction.
Methods:
A total of 119 patients were referred for echocardiography to evaluate ventricular function. Patients with reduced systolic function were excluded. Patients were divided on the basis of normal or reduced LV diastolic function determined by echocardiography. CAVI was measured using an automatic waveform analyzer.
Results:
CAVI was significantly higher in patients with reduced LV diastolic function than those with normal LV diastolic function (9.0+/-1.1 and 8.5+/-1.1, p=0.009). Multiple linear regression analysis revealed that CAVI was independently associated with the ratio of peak early diastolic velocity to peak atrial diastolic velocity and left atrial diameter. When patients were classified on the basis of CAVI quartiles, multiple logistic regression analysis demonstrated that the highest quartile of CAVI showed an increased odds ratio for the presence of LV diastolic dysfunction.
Conclusion:
The present study revealed that an increased CAVI was independently associated with LV diastolic dysfunction in patients with preserved systolic function.
