147 - Key Recommendations from the 2022 AHA/ACC/HFSA Heart Failure Guidelines

In this episode, we review new updates and key concepts from the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure. This guideline is newly published (April 2022) and is a full update of the 2013 guidelines and the 2017 focused update for heart failure. Key Concepts Heart failure is classified as HFrEF (heart failure with reduced ejection fraction <= 40%), HFimpEF (with improved ejection fraction – was <=40% but is now > 40%), HFmrEF (ejection fraction 41% to 49% with increased LV filling pressures), and HFpEF (preserved ejection fraction >= 50% with increased LV filling pressures). Most drug therapy recommendations are similar for HFrEF, HFimpEF, and HFmrEF whereas HFpEF therapies are different. The 2022 AHA/ACC/HFSA heart failure guidelines now recommend SGLT2 inhibitors, such as dapagliflozin and empagliflozin, in patients with HFrEF, HFmrEF, and HFpEF. The 2022 AHA/ACC/HFSA heart failure guidelines continue to prefer ARNi, such as sacubitril/valsartan (Entresto), over ACE inhibitors and ARBs in patients with HFrEF. Based on the PARAGON-HF trial, ARNi is also recommended in those with HFpEF albeit with a weak recommendation. Avoiding excessive dietary sodium is reasonable to reduce congestive symptoms in patients with heart failure; however, guidelines do not recommend a specific maximum intake nor does data support clinical outcome benefit with dietary sodium restriction.
