Multivariate regression analysis of the association between left atrial functional parameters and gout stage between study groups (n = 173).

PALS, Peak atrial longitudinal strain; ALS-syst, peak atrial longitudinal strain rate during ventricular systole; ALS-early, peak atrial longitudinal strain rate during ventricular early diastole; ALS-late, peak atrial longitudinal strain rate during ventricular late diastole. Absolute values of ALS-early and ALS-late were used in multivariate regressions.*Including gout stage.†Adjusted for age, uric acid, creatinine and left ventricular (LV) mass index.‡Adjusted as model 1, pluse ratio of the transmitral and myocardial peak early diastolic velocities (E/Em), LV global longitudinal systolic strain (LVε).Multivariate regression analysis of the association between left atrial functional parameters and gout stage between study groups (n = 173).
