Insights
The number of patients and inclusion of dialysis populations significantly impact the prognostic prediction success of arterial stiffness indices like brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI). Arteriosclerosis obliterans exclusion criteria are also important.
Area of Science:
- Cardiovascular Research
- Biomedical Engineering
- Clinical Diagnostics
Background:
- Arterial stiffness is a key indicator of cardiovascular risk.
- Brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI) are established measures of arterial stiffness.
- A comprehensive review of their prognostic significance is lacking.
Purpose of the Study:
- To systematically review the prognostic significance of baPWV and CAVI.
- To identify factors influencing the success of prognostic prediction using these indices.
- To evaluate the impact of arteriosclerosis obliterans (ASO) exclusion criteria.
Main Methods:
- Systematic review of studies assessing prognostic significance of baPWV and CAVI.
- Definition of "successful" studies as those showing independent significance in multivariate Cox proportional hazards analysis.
- Comparison of success rates using Fisher's exact test and logistic regression for determinant analysis.
Main Results:
- The success rate for baPWV (65.7%) was higher than for CAVI (40.0%).
- Larger patient numbers (log) and inclusion of dialysis populations were independent determinants of successful prognostic prediction.
- Exclusion criteria for ASO showed a statistical tendency to influence prognostic prediction success.
Conclusions:
- Study participant numbers and the inclusion of dialysis populations are critical for successful prognostic prediction with baPWV and CAVI.
- Proper application of ASO exclusion criteria is important for accurate interpretation.
- Further large-scale prospective studies are needed to confirm the superiority of these indices in prognostic prediction.
Background:
Brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI) are indices of arterial stiffness, and several studies have used these indices. However, there is no comprehensive review of these parameters in the prognostic significance.
Methods:
The aim of this study was to review the articles exploring the prognostic significance of these parameters. Articles demonstrating independent significance after multivariate analysis on the Cox proportional hazards model were defined as "successful." The success rate was compared using Fisher's exact test. In addition, multivariate logistic regression analysis was performed to explore the independent determinants of the success of prognostic prediction.
Results:
The success rate of the baPWV articles (65.7% [46/70]) tended to be higher than that of the CAVI articles (40.0% [6/15]; P=0.083). Multivariate analysis demonstrated that log (number of patients) (OR 11.20, 95% CI 2.45-51.70, P=0.002) and dialysis population (OR 0.28, 95% CI 0.08-0.94, P=0.039) were positive and negative independent determinants of the success of prognostic prediction, respectively. In addition, after redefining two studies as the absence of arteriosclerosis obliterans (ASO) exclusion, baPWV (OR 3.36, 95% CI 0.86-13.20, P=0.083) and the existence of exclusion criteria of ASO (OR 3.08, 95% CI 0.96-9.93, P=0.060) exhibited statistical tendency in the multivariate analysis.
Conclusion:
This study demonstrated that the number of study participants and dialysis population were the independent determinants of the success of prognostic prediction. This study also showed the importance of exclusion criteria of ASO when using these indices. In addition, a prospective large-scale study to confirm the superiority in the prognostic prediction of these indices is warranted.
