Heart failure continues to pose a major health threat in the United States, with approximately 6.7 million adults currently living with the condition. Alarming projections suggest that this number could climb to more than 8 million by 2030.However, a promising new analysis published in Circulation: Heart Failure reveals that hospitals involved in the American Heart Association’s multiregional IMPLEMENT-HF initiative have significantly improved their adherence to guideline-directed medical therapy for patients with heart failure with reduced ejection fraction (HFrEF)—the most prevalent form of heart failure.Launched in 2021, the American Heart Association’s three-year quality improvement initiative was designed to drive the uptake of quadruple medical therapy and incorporate assessments of patients’ health-related social needs into standard care. This quadruple therapy includes a combination of four proven, evidence-based drugs that reduce mortality: angiotensin receptor–neprilysin inhibitor (ARNI), evidence-based specific β-blocker (BB), mineralocorticoid antagonist (MRA), and sodium-glucose cotransporter 2 inhibitor (SGLT2i).The initiative built upon the Association’s long-running Get With The Guidelines® - Heart Failure program and involved over 100 hospitals nationwide. The latest study, drawing on data from more than 43,000 patients across 67 participating hospitals, highlighted several key outcomes:The use of all four recommended drug classes for HFrEF patients increased from 4.7% to 44.6% at hospital discharge and from 0% to 44.8% within 30 days after discharge.The improvement in care was observed consistently across race, ethnicity, and gender.Hospitals also made significant strides in implementing tools to assess patients’ social needs, marking a vital step toward equitable heart failure care."This initiative represents an important leap forward in closing the treatment gap in heart failure," said Dr. Andrew Sauer, a volunteer with the American Heart Association, lead author of the study, and cardiologist at Saint Luke’s Mid America Heart Institute in Kansas City. "By supporting collaborative learning and leveraging real-time data, IMPLEMENT-HF enabled hospitals to better serve patients in varied communities."HFrEF accounts for nearly half of all heart failure hospitalisations and is associated with a grim five-year mortality rate of 75%. Although clinical trials have long demonstrated that quadruple therapy can significantly enhance survival, its adoption has remained frustratingly low across the U.S., especially among underserved and underrepresented populations.The IMPLEMENT-HF initiative created a collaborative “all-teach, all-learn” environment that empowered participating hospitals to identify care gaps, share effective practices, and monitor outcomes at both the local and regional levels.The impressive results underscore the value of collaboration in healthcare. “The improvements we’ve seen through IMPLEMENT-HF highlight the power of teamwork,” the American Heart Association said in a statement. “We remain committed to transforming systems of care to ensure every person—regardless of where they live—has access to the highest standard of heart failure treatment."
