This Week in Cardiology: SGLT2 Inhibitors and Heart Failure Management
A flurry of research this week focused on the role of SGLT2 inhibitors in heart failure management, particularly in older patients. From the Archives of Gerontology and Geriatrics, a meta-analysis of 20,844 patients aged 65+ found that SGLT2 inhibitors were associated with reduced all-cause mortality (HR 0.81) and heart failure hospitalization (HR 0.73) [1].
The analysis pooled data from 10 studies, including both randomized trials and observational cohorts, suggesting these medications may be a valuable consideration for older HF patients. Meanwhile, JAMA Internal Medicine reported on a secondary analysis of a phase 3b trial evaluating oral semaglutide in patients with type 2 diabetes and heart failure history [2].
While the study found no overall benefit for cardiovascular risk reduction, there was a significant reduction in composite heart failure outcomes specifically among participants with baseline heart failure. This suggests potential benefits for those with established heart failure, though further research is needed to confirm broader cardiovascular risk reduction.
