Abstract: Objective To explore the value of left atrium volume index (LAVI) in the diagnosis of heart failure with preserved ejection fraction (HFPEF). Methods Seventy-seven patients with HFPEF and 33 patients without HFPEF who had been treated from May 2012 to September 2013 in Guangdong General Hospital were en-rolled. The clinical data and a series of ultrasound parameters were collected and analysed. The relationship between LAVI, LAV, and other indexes of diastolic function was determined by Pearson correlation analysis. The value of LAVI and LAV for diagnosing HFPEF was compared by the ROC curve. Results LAVI and LAV of were signifi-cantly greater in HFPEF group than in non-HFPEF group. LAV and LAVI were significantly associated wtih HEPEF. The area under the ROC curve (AUC) of LAVI increased significantly as compared with the AUC of LAV (0.832 vs. 0.799, P<0.05). With a cut-off value of 30 mL/m2, the specificity and sensitivity for diagnosing HEPEF were 64.9%and 84.8%, respectively. Conclusions LAVI may be valuable in the diagnosis of HFPEF.
