摘要

Background

The population with cardiovascular–kidney–metabolic (CKM) syndrome has a higher risk of cardiovascular events. Chinese visceral adiposity index (CVAI), an index of both visceral obesity and surrogate insulin resistance, has been linked to cardiovascular events. However, the nature of this relationship remains unclear in individuals with CKM syndrome.

Methods

All data came from the China Health and Retirement Longitudinal Study (CHARLS). The association between CVAI and cardiovascular events risk was explored using Cox regression models, restricted cubic spline (RCS) curves, and multiple sensitivity analyses. To compare the predictive abilities of various indices, receiver operating characteristic (ROC) analyses were employed.

Results

7744 participants were in final analysis. During 9 year follow-up, 1679 cases of cardiovascular disease (CVD), 1,255 cases of heart disease, and 604 cases of stroke were recorded. Cox regression analyses revealed that per-SD (standard deviation) increase in CVAI, the risk of CVD, heart disease, and stroke increased by 22% (95% CI 1.13–1.32), 22% (95% CI 1.13–1.32), and 32% (95% CI 1.19–1.47). In participants at CKM stage 3 with CVD, a J-shaped curve was observed in the RCS analyses (P non-linearity = 0.036). Subgroup analysis revealed an interaction between age and each 10-unit increase in CVAI in CVD (P interaction = 0.0173) and stroke risk (P interaction = 0.028). The AUC (area under curve) value for CVAI was highest compared to other indicators (all DeLong Test P values < 0.05).

Conclusions

This research demonstrates a higher CVAI was linked to increased cardiovascular risk in individuals with CKM syndrome stage 0–3. Monitoring CVAI can help identify high-risk individuals early and improve the effectiveness of disease management.
