Abstract
- Heart failure (HF) with mid-range ejection fraction (HFmrEF) is defined as HF with a left ventricular (LV) ejection fraction (LVEF) of 41-49%. However, the change in LV function and the subsequent prognosis in these patients remain unclear. We aimed to investigate whether LV global longitudinal strain (LV GLS) could differentiate the changes in LVEF and predict the clinical outcomes in patients with HFmrEF.According to the changes in LVEF on follow-up echocardiography, 273 outpatients with HFmrEF were divided into 3 groups: HFwEF (HF with worse EF:40%), HFsEF (HF with similar EF: 40-49%), and HFrecEF (HF with recovered EF:50%). Further, the LV GLS at diagnosis was evaluated.The average follow-up duration was 31 months. Among patients with HFmrEF, the more impaired the LV GLS at baseline, the higher probability of HFwEF development. In comparison with patients with HFwEF and HFsEF, those with HFrecEF had a lower risk of hospitalization for HF. At a cut-off value of -11%, LV GLS differentiated the subsequent risk of cardiovascular death in patients with HFmrEF. In Cox regression, patients with LV GLS-11% had a high risk of cardiovascular death.In patients with HFmrEF, LV GLS is associated with LVEF changes and subsequent cardiovascular death. Patients with HFrecEF had a lower risk of hospitalization for HF.
