Imaging criteria for the diagnosis of heart failure with midrange and preserved LVEF in the real life

Abstract : Background According to last ESC guidelines, the diagnosis of heart failure with midrange and preserved left ventricular ejection fraction (HFmrEF-HF and HFpEF) requires at least one of the following imaging criteria: LV hypertrophy with LVMI >115g/m$^2$ in men and 95g/m$^2$ in women, left atria dilation with LAVI >34ml/m$^2$, TDI e' wave average <9cm/s and E/e' average ≥13. Purpose We analyzed the prevalence of these imaging criteria in real life patients who are labeled HFmrEF or HFpEF by using a multicenter survey on HF. Methods Our survey (NCT01956539) was carried out in 32 hospitals between 2015 and 2018 and included 2735 HF patients who gave their consent during consultation or hospitalization. The diagnosis of HF was left to the discretion of investigators. Besides clinical and biological data, echocardiographic data (<1 month before or <3 months after inclusion) was collected in an electronic database. No echographic variable except the LVEF was mandatory to be included. Results Among the 523 and 765 HF patients who were labeled respectively as HFmrEF-HF and HFpEF, the 4 echographic variables required for the diagnosis of HFmrEF or HFpEF were obtained in 512 patients. The median age was 74y [IQR 62–82], HF was de novo in 28%, AF in 34%, median NTproBNP was 1563 pg/mL [IQR 500–4372]. At least one of the 4 diagnostic criteria was present in all patients but 2, and patients had 2, 3 or 4 criteria in 43%, 37% and 1% of cases. The table shows only little differences between HFmrEF and HFpEF or de novo HF regarding the rate of each diagnostic criteria. There was no difference regarding the date of inclusion, i.e. before or after the last ESC guidelines. Conclusion: The diagnosis of HFpEF or mrEF may be difficult and requires comprehensive echocardiography including all diagnostic variables because each single diagnostic criteria are present in only 33 to 80% cases
