Managing HFrecEF
Management should include assessment of jugular vein distention and signs of volume overload – “particularly concerning in HFrecEF” – the panel noted. ECG is cost effective, and signs of left-bundle branch block are predictors of low success with GDMT alone. The panel also recommended a family history going back three generations and consideration of genetic testing to determine the risk for sudden cardiac death. Two-dimensional ECG can help predict GDMT response and cardiovascular magnetic resonance imaging can provide information about myocardial substrate at the time of diagnosis of HFrEF.
The panel suggested four areas for future research: 1) improved phenotyping of HFrEF; 2) use of inception cohorts to better understand the natural history of HFrecEF; 3) clinical trials to better define those clinical care components most effective at maintaining remission; and 4) basic studies to better define the biology of HFrecEF. “The goal,” wrote Dr. Wilcox and colleagues, “is to develop new therapeutic targets that will enable patients with HFrecEF to experience a durable remission from HF.”
