Chinese visceral adiposity index and its relation to abnormal left ventricular remodeling assessed by relative wall thickness and left ventricular mass index

The Chinese visceral adipose index (CVAI) is more significantly associated with cardiometabolic risk factors than other obesity indices. This study investigated the relationship between CVAI and left ventricular (LV) remodeling. This study included 75,132 Koreans who underwent echocardiography during a health checkup. They were grouped according to quartile levels of the CVAI, body mass index (BMI), waist circumference (WC), and visceral adiposity index (VAI). LV remodeling was defined as the presence of abnormal relative wall thickness (ARWT) and left ventricular hypertrophy (LVH). Multivariate adjusted logistic regression analysis (adjusted OR [95% confidence interval]) was used to analyze the association between ARWT and LVH according to the quartile levels of each index. Receiver operating characteristic (ROC) graphs and areas under the curve (AUC) were calculated to identify the predictive ability of the indices for ARWT and LVH. ARWT was associated proportionally with CVAI quartiles in both men (second quartile: 1.42 [1.29–1.56], third quartile: 1.61 [1.46–1.77], fourth quartile: 2.01 [1.84–2.21]), and women (second quartile: 1.06 [0.78–1.45], third quartile: 1.15 [0.86–1.55], and fourth quartile: 2.09 [1.56–2.80]). LVH was significantly associated with third (1.74 [1.07–2.83]) and fourth quartile (1.94 [1.18–3.20]) groups of CVAI in women. ROC and AUC analyses indicated that CVAI was superior to other indices in predicting ARWT in men and LVH and ARWT in women. The CVAI is an effective surrogate marker of LV remodeling, particularly in women. •CVAI predicted the likelihood of LVH and ARWT better than BMI, waist circumference, and VAI in women.•Our study suggests that the VAI has poor predictive power for LV remodeling, whereas the CVAI is significantly better in the Asian population.
