The DeepECG-HFrEF algorithm may help in identification of LVSD and of patients at risk of worse survival in resource-limited settings. HFrEF (+) was associated with higher mortality rates. The DeepECG-HFrEF algorithm can discriminate HFrEF in a real-world HF cohort with acceptable performance. Those classified as HFrEF (+) showed lower survival rates than HFrEF (−) (log-rank p < 0.001). The AUC value was 0.844 for identifying HFrEF among patients with acute symptomatic HF. HFrEF (+) identified an EF < 40% and HFrEF (−) identified EF ≥ 40%. A total of 690 patients contributing 18,449 ECGs were included with final 1291 ECGs eligible for the study (mean age 67.8 ± 14.4 years men, 56%). The 5-year mortality according to DeepECG-HFrEF results was analyzed using the Kaplan–Meier method. The performance of DeepECG-HFrEF was determined using the area under the receiver operating characteristic curve (AUC) values. Symptomatic HF patients admitted at Seoul National University Hospital between 20 were included. The DeepECG-HFrEF algorithm was trained to identify left ventricular systolic dysfunction (LVSD), defined by an ejection fraction (EF) < 40%.

The performance and clinical implications of the deep learning aided algorithm using electrocardiogram of heart failure (HF) with reduced ejection fraction (DeepECG-HFrEF) were evaluated in patients with acute HF.
