Abstract Background In patients with heart failure (HF) and reduced left ventricle ejection fraction (LVEF), the sodium-glucose cotransporter inhibitor (iSGLT2) dapagliflozin has recently been shown to reduce the risk of worsening heart failure or death from cardiovascular causes in the DAPA-HF trial. Results of iSGLT2 in HF with preserved LVEF are awaited. Our goal was to investigate how many patients in a real-world setting would be eligible for dapagliflozin according to the DAPA-HF criteria. Methods This is a single-center retrospective study enrolling consecutive patients followed in an HF Clinic from 2013 to 2019. The key DAPA-HF inclusion criteria [i.e., Left Ventricular Ejection Fraction (LVEF) <40% and NT-proBNP >600pg/mL (or >900pg/ml if AF)] and exclusion criteria [estimated glomerular filtration rate (eGFR) <30ml/kg/1.73m2, systolic blood pressure (SBP) <95mmHg] were considered. Results Overall, 479 patients (mean age 75.7±12.8 years; 50.4% male; 78.8% with hypertension; 45.0% with an eGFR <60ml/min/1.73m2; 36.5% with type 2 diabetes mellitus; 33.5% ischaemic HF) were assessed. Of these, 155 (33.2%) patients had LVEF <40%. Patients had a mean SBP of 131±28 mmHg, a median eGFR of 48 (IQR 33–65) ml/min/m2 and a NT-proBNP of 2183 (IQR 1010–5310) pg/mL Overall, according to the DAPA-HF trial key criteria, 88 patients (18.3%) would be eligible for dapagliflozin. The remainder would be excluded due to a LVEF>40% (67.5%), eGFR <30 ml/min/1.73m2 (19.4%), NT-proBNP <600 pg/mL (or <900 pg/mL if AF) (16.7%) and/or SBP <90mmHg (2.1%) (figure 1). If we limit the analysis to those with a LVEF <40%, 56.7% would be eligible for dapagliflozin. The remainder would be excluded due to a eGFR <30ml/kg/1.73m2 (20%), NT-proBNP <600 pg/mL (or <900 pg/mL if AF) (16.1%) and/or SBP <90mmHg (8.4%) (figure 1). Conclusion Roughly one in every five patients in our real-world HF cohort would be eligible to start dapagliflozin according to the key criteria of the DAPA-HF trial. The main reason for non-eligibility was a LVEF >40%. These findings highlight the urgent need for disease-modifying drugs in mid-range and preserved LVEF. The results of ongoing iSGLT2 trials in these LVEF subgroups are eagerly awaited. Funding Acknowledgement Type of funding source: None
