Researchers provided further evidence supporting the use of SGLT2 inhibitors for nearly all types of heart failure cases. Last week, the Journal of the American College of Cardiololgy published an original investigation in which an international team of researchers dig into a fundamental question: when should SGLT2i medications be initiated?
The authors performed a secondary analysis of the DELIVER trial to investigate whether the SGLT2 inhibitor dapagliflozin reduced the risk of worsening HF or cardiovascular death, even for patients who were hospitalized for HF within the previous 30 days. About 10% of the DELIVER patients (n = 654) met this criterion. Not too surprisingly, these patients were sicker at baseline and had higher event rates than those who were not recently hospitalized:
- Patients with recent HF hospitalization were almost twice as likely to experience cardiovascular death or worsening HF after multivariable adjustment (HR: 1.88).
This cohort may have been more vulnerable, but they still reaped the benefits of dapagliflozin:
- Dapagliflozin reduced the primary outcome (worsening HF events or CV death) by 22% in recently hospitalized patients, compared to 18% in patients who were not recently hospitalized.
- The recent hospitalization group also showed consistent quality of life improvement.
- Dapagliflozin did not increase adverse event rates in either group.
Though evidence continues to accumulate supporting the use of SGLT2 inhibitors (see EMPULSE and SOLOIST), financial barriers still exist, making them inaccessible to many patients. The current list prices for dapagliflozin and empagliflozin (two common SGLT2is) are $548 and $570, respectively, and 40% of Medicare Part D beneficiaries pay about $163 out-of-pocket each month.
A vast body of evidence supports prescribing SGLT2 inhibitors for HF. Insights from the present study provide practical evidence to substantiate the initiation of SGLT2 inhibitors during or right after a hospitalization for heart failure. But more work lies ahead to make this heart failure solution financially accessible to patients.
