<p>Background:Left ventricular ejection fraction (LVEF) is a basic clinical index that determines the heart failure (HF) treatment strategy. We aimed to evaluate the association between hospitalization costs for HF patient and LVEF in an advanced aging society in a region in Japan.</p><p>Methods and Results:Consecutive HF patients admitted to Miyazaki Prefectural Nobeoka Hospital between January 2015 and March 2018 were included in the study. The 346 HF patients (mean age 78 years) were divided into 2 groups: HF with reduced ejection fraction (HFrEF; LVEF <40%; n=129) and HF with preserved ejection fraction (HFpEF; LVEF ≥40%; n=217). Median hospitalization costs (in 2017 US dollars) were higher in the HFrEF than HFpEF group, but the difference was not statistically significant (&#36;7,128 vs. &#36;6,580; P=0.189). However, in older adults (age ≥75 years; n=252), median hospitalization costs were significantly higher in the HFrEF than HFpEF group (&#36;7,240 vs. &#36;6,471; P=0.014), and LVEF was an independent factor of hospitalization costs (β=−0.0301, P=0.006). Median hospitalization costs were significantly lower in the older than younger HFpEF group (&#36;6,471 vs. &#36;7,250; P=0.011), but there was no significant difference in costs between the older and younger HFrEF groups (&#36;7,240 vs. &#36;6,760; P=0.351).</p><p>Conclusions:The relationship between LVEF and hospitalization costs became more pronounced with age, and LVEF was a negative independent factor for hospitalization costs in the older population.</p>
