Inappropriate left ventricular mass index (LVM) may develop as a response to particular hemodynamic and metabolic alterations. Inappropriate LVM and peripheral artery disease (PAD) characterized by abnormally low or high ankle-brachial index (ABI) are common in chronic kidney disease (CKD) patients, in whom there may be a close and cause-effect relationship. The aim of this study is to assess whether CKD and abnormal ABI has an independent and additive association with inappropriate LVM. A total of 1110 patients were included in the study. Inappropriate LVM was defined as observed LVM more than 28% of the predicted value. The ABI was measured using an ABI-form device. PAD was defined as ABI %26lt;0.9 or %26gt;= 1.3 in either leg. Multivariate analysis showed that patients with estimated glomerular filtration rate (eGFR) %26lt;45 ml/min/1.73 m(2) (odds ratio [OR], 1.644; P = 0.011) and PAD (OR, 2.082; P = 0.002) were independently associated with inappropriate LVM. The interaction between eGFR %26lt;45 ml/min/1.73 m(2) and PAD on inappropriate LVM was statistically significant (P = 0.044). Besides, eGFR %26lt;45 ml/min/1.73 m(2) (change in observed/predicted LVM, 19.949; P%26lt;0.001) and PAD (change in observed/predicted LVM, 11.818; P = 0.003) were also significantly associated with observed/predicted LVM. Our findings show that eGFR %26lt;45 ml/min/1.73 m(2) and PAD are independently and additively associated with inappropriate LVM and observed/predicted LVM. Assessments of eGFR and ABI may be useful in identifying patients with inappropriate LVM.
