Current evidence supports the early initiation of all guideline-directed medical therapy (GDMT) in patients with heart failure with reduced ejection fraction (HFrEF), but clinical inertia persists in real-world practice. Clinical data of 343 HFrEF patients hospitalized from January 2018 to December 2019 were collected, and they were followed for at least 3 years. We analyzed the benefits of optimizing GDMT at hospital discharge, the reasons for underprescription of GDMT, and factors associated with different outcomes after multivariate adjustments. Starting at least 3 pillars of GDMT at hospital discharge significantly reduced the risks of all-cause mortality, cardiovascular (CV) death, and heart failure hospitalization (hazard ratio = 0.22, 0.21, 0.28, respectively; all p < 0.001). Renal impairment was the major factor associated with the non-optimization of GDMT, and 78.4% of patients receiving fewer than 3 pillars of GDMT had a baseline chronic kidney disease stage 3-5. However, the prescription of GDMT was not associated with any observable risk of adverse renal outcomes. This study demonstrated the CV benefits and safety regarding renal outcomes with the early initiation of GDMT in HFrEF patients. Efforts should be made to address the disparity between evidence-based medicine and daily practice.
