The SGLT2 inhibitor dapagliflozin scored a clear win in a randomized, controlled trial with more than 300 U.S. patients with heart failure with preserved ejection fraction (HFpEF), showing a significant and clinically meaningful benefit for the primary endpoint, a KCCQ measure of symptoms and physical limitations, after 12 weeks of treatment.

In the PRESERVED-HF study, patients with HFpEF who received a standard, once-daily dose of dapagliflozin (Farxiga) had an average 5.8-point improvement in their condition as measured by the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CS), the study’s primary endpoint.

This is “the first study to demonstrate that an SGLT2 inhibitor dapagliflozin significantly improves symptoms, physical limitations, and 6-minute walking distance in patients with HFpEF,” Mikhail N. Kosiborod, MD, reported at the annual scientific meeting of the Heart Failure Society of America. The secondary endpoint of 6-minute walking distance “has been very difficult to improve in many previous studies of other treatments” tested in patients with HFpEF, noted Dr. Kosiborod, a cardiologist and co-director of the Cardiometabolic Center of Excellence at Saint Luke’s Mid-America Heart Institute.
