Bringing SGLT2 inhibitors into heart failure management
Dr. Yancy also cited recently reported data from another landmark trial, DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure), as an impetus for both another immediate change to the guideline and for a potential second change pending a report of confirmatory evidence that may arrive in 2020.
The DAPA-HF results showed that the sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin (Farxiga) was just as effective for preventing all-cause death and heart failure hospitalizations and urgent visits in patients without type 2 diabetes as it is in patients with type 2 diabetes (N Engl J Med. 2019 Nov 21;381[21]:1995-2008), a remarkable finding for an agent that came onto the U.S. market as a diabetes drug specifically aimed at reducing levels of glycosylated hemoglobin.
DAPA-HF: Dapagliflozin’s HFrEF efficacy confirmed in nondiabetics
Dr. Yancy proposed an immediate guideline change to acknowledge the proven protection against incident heart failure that treatment with a SGLT2 inhibitor gives patients with type 2 diabetes. There is now “a strong opportunity to use an SGLT2 inhibitor in patients with type 2 diabetes to reduce the incidence of heart failure,” he said.
And he added that, if results from EMPEROR REDUCED (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Reduced Ejection Fraction), studying the SGLT2 inhibitor empagliflozin (Jardiance) in HFrEF patients with and without type 2 diabetes, can confirm the efficacy of a second drug from this class in preventing heart failure events in patients with HFrEF but without diabetes, then the time will have arrived for another guideline change to establish the SGLT2 inhibitors as a new “foundational” drug for the management of all HFrEF patients, regardless of their level of glycemic control. The SGLT2 inhibitors are a particularly attractive additional drug because they are taken once daily orally with no need for dosage adjustment, so far they have shown excellent safety in patients without diabetes with no episodes of hypoglycemia or ketoacidosis, and they have even shown evidence for heart failure benefit in patients older than 75 years, Dr. Yancy noted.
Dr. Yancy had no relevant disclosures.
