Insights
Common carotid artery stiffness, a marker of proximal aortic stiffness, is linked to heart structure and function. This stiffness, unlike carotid-femoral pulse wave velocity, predicts acute heart failure development in at-risk patients.
Area of Science:
- Cardiovascular Medicine
- Biomedical Engineering
- Clinical Research
Background:
- Proximal aortic stiffness is implicated in heart failure pathogenesis.
- Carotid-femoral pulse wave velocity (cf-PWV) is a common measure of arterial stiffness.
- Common carotid artery (CCA) stiffness may serve as a surrogate for proximal aortic stiffness.
Purpose of the Study:
- To investigate the association between CCA stiffness and left ventricular (LV) structure and function.
- To determine if CCA stiffness predicts the development of acute heart failure (AHF).
- To compare the predictive value of CCA stiffness with cf-PWV for AHF.
Main Methods:
- 114 outpatients without prior heart failure underwent cardiovascular assessments.
- Echocardiography measured LV mass index, LV ejection fraction (EF), and E/E'.
- Carotid ultrasonography assessed CCA mechanical properties (Einc, β stiffness index, CD, CS); cf-PWV was measured by tonometry.
Main Results:
- CCA distensibility (CD) correlated with LV mass index.
- All CCA stiffness indices were associated with LV EF and E/E', independent of age, blood pressure, and cf-PWV.
- CCA stiffness indices (Einc, CS, β stiffness index) significantly predicted AHF events, whereas cf-PWV did not.
Conclusions:
- CCA stiffness is significantly associated with LV structure and function in patients at risk for heart failure, independent of cf-PWV.
- CCA stiffness, not cf-PWV, serves as a significant predictor of first acute heart failure events.
Aims:
Proximal aortic stiffness may be more important than carotid-femoral pulse wave velocity (cf-PWV) in the pathogenesis of heart failure. The present study investigated the associations of common carotid artery (CCA) stiffness, which might be a surrogate for proximal aortic stiffness, with left ventricular (LV) structure and function, and the development of acute heart failure (AHF).
Methods And Results:
Outpatients without a history of heart failure (114 subjects aged 63.5 ± 17.5 years) were enrolled for comprehensive noninvasive cardiovascular examinations. The LV mass index, the LV ejection fraction (EF), and the ratio of the early diastolic transmitral flow velocity to the early septal mitral annular diastolic velocity (E/E') were measured by echocardiography. CCA mechanical properties, including the incremental elastic modulus (Einc), β stiffness index, CCA distensibility (CD) and circumferential strain (CS), were assessed by carotid artery ultrasonography. cf-PWV was measured by arterial tonometry. CD was significantly associated with the LV mass index, and all CCA stiffness indices were significantly associated with EF and E/E' independently of age, mean blood pressure, and cf-PWV. During a mean follow-up of 265 ± 106 days, 9 patients presented with AHF. Einc (hazard ratio 6.56, 95% confidence interval 1.64-26.26, by quartile analysis), CS (6.82, 1.70-27.35), and β stiffness index (3.91, 1.05-14.57) but not cf-PWV (1.62, 0.41-6.51) significantly predicted the events.
Conclusions:
In patients at risk for heart failure, CCA stiffness was significantly associated with LV structure and function independently of cf-PWV. In addition, CCA stiffness but not cf-PWV predicted first AHF.
