Authors' conclusion

In patients with obesity-related HFpEF, semaglutide reduced NT-proBNP. Participants with higher baseline NT-proBNP had a similar degree of weight loss but experienced larger reductions in HF-related symptoms and physical limitations with semaglutide than those with lower NT-proBNP.
