The treatment and management of heart failure (HF) are constantly evolving. The latest guidelines recommend the use of SGLT2 inhibitors (SGLT2i) as an integral part to treating HF with reduced ejection fraction (< 40%). However, given that the patients included in these trials do not reflect the heterogeneity of the health of many elderly patients, we recommend basing the therapeutic decision on the patient's state of frailty. If a SGLT2i treatment at a standard dose (10 mg 1x/day) is recommended for robust patients, we suggest initiating treatment at 5 mg 1x/day for vulnerable patients, and then after 1 month increasing the dose to 10 mg 1x/day. Finally, for dependent patients, we recommend therapeutic abstention in the absence of sufficient scientific evidence.
