Insights
Arterial stiffness, measured by cardio-ankle vascular index (CAVI) and pulse wave velocity (PWV-cf), significantly correlates with aging and comorbidity burden. CAVI and CAVI0 show a stronger link to aging than PWV-cf.
Area of Science:
- Gerontology
- Cardiovascular Medicine
- Biomedical Engineering
Background:
- Arterial stiffness is a key indicator of cardiovascular health.
- Aging and comorbidity significantly impact vascular function.
- Existing measures like pulse wave velocity (PWV-cf) and cardio-ankle vascular index (CAVI) assess arterial stiffness.
Purpose of the Study:
- To investigate the relationships between carotid-femoral pulse wave velocity (PWV-cf), cardio-ankle vascular index (CAVI), and CAVI0 with age and comorbidity burden.
- To identify predictors of arterial stiffness in an aging population with comorbidities.
Main Methods:
- Cross-sectional study involving 183 patients (mean age 67.5 years) from a geriatric clinic.
- Collected demographic, clinical, and blood analysis data.
- Measured PWV-cf, CAVI, CAVI0, and Charlson Comorbidity Index (CCI).
- Utilized stepwise multiple regression analysis.
Main Results:
- Significant positive correlations were found between CAVI, CAVI0, PWV-cf, and both age and CCI (p < 0.001).
- CCI was the sole predictor of PWV-cf in regression analysis.
- Age and CCI were significant predictors of both CAVI and CAVI0.
Conclusions:
- All assessed arterial stiffness indices (PWV-cf, CAVI, CAVI0) are associated with aging and comorbidity burden (CCI).
- CAVI and CAVI0 demonstrate a stronger correlation with aging compared to PWV-cf.
- Arterial stiffness parameters offer valuable insights into the complexity of aging individuals with significant comorbidities.
Abstract:
The aim of the study was to evaluate the relationships between carotid-femoral pulse wave velocity (PVW-cf), cardio-ankle vascular index (CAVI) and CAVI0 (which is a mathematical elaboration of CAVI, theoretically less dependent on blood pressure), age and comorbidity burden. Furthermore, 183 patients (119 female, mean age 67.5 ± 14.3 years) referred to the Geriatric Ward and Outpatient Clinic at Verona University Hospital were included; demographic, clinical and blood analysis data were collected. Charlson Comorbidity Index (CCI), PVW-cf, CAVI and CAVI 0 were obtained. Significant correlations were found between CAVI, CAVI0, PVW-cf and both age (r = 0.698, r = 0.717, r = 0.410, respectively p < 0.001 for all) and CCI, (r = 0.654; r = 0.658; r = 0.448 respectively and p < 0.001 for all), still significant after adjustment for several variables. In a stepwise multiple regression model, considering several variables, CCI was the only predictor of PWV-cf, whereas age and CCI were significant predictors of both CAVI and CAVI 0. In conclusion, all arterial stiffness indexes are associated with CCI and aging; the latter correlation is more evident for CAVI and CAVI 0 than for PVW-cf. Arterial stiffness parameters can complement the characterization of patients affected by a remarkable comorbidity burden across aging; arterial stiffening might mirror the complexity of these individuals.
