Correlation of dIVC and △VTI. a Correlation of dIVC and △VTI in all patients, r = 0.535, p < 0.001. b Correlation of dIVC and △VTI in ILVD patients, r = 0.196, p = 0.309. c Correlation of dIVC and △VTI in NLVF patients, r = 0.722, p < 0.001. Correlation of dIVC and △VTI derived from NLVF patients was strengthened than that derived from all patients, p = 0.020. ILVD isolated left ventricular systolic dysfunction, NLVF normal left ventricular function; dIVC inferior vena cava distensibility index, △VTI velocity–time integral change after passive leg raising
