A scoring evaluation for the practical introduction of guideline‐directed medical therapy in heart failure patients

Abstract

AimsThe guideline‐directed medical therapy (GDMT) has been recommended for heart failure (HF) with reduced ejection fraction (HFrEF) based on the accumulating clinical evidence. However, it is difficult to implement all the trial‐proven medications for every patient in the real world.Methods and resultsA simple GDMT score was created, according to the combination of GDMT drugs (renin–angiotensin system inhibitors, beta‐blockers, mineralocorticoid receptor antagonists, and sodium–glucose transporter 2 inhibitors) administration and their dosage (0–9 points). Its impact on the prognosis of HF patients was investigated. Admitted HF patients [HFrEF and HF with mildly reduced ejection fraction (HFmrEF), n = 1054] were retrospectively analysed (excluding those with in‐hospital death and dialysis). A simple GDMT score ≥5, but not the number of medications, was significantly associated with a reduction of all‐cause death, HF readmission, and composite outcome (HF readmission and all‐cause death) (P < 0.001). Subgroup analysis showed that almost all groups with a simple GDMT score of 5 or higher had a better prognosis.ConclusionsThe developed simple GDMT score was associated with prognosis in HFrEF and HFmrEF patients. Even if all four drugs cannot be introduced for some reason, a regimen with a simple GDMT score ≥5 may lead to a prognosis in HF patients.
