Key result
Subclinical congestion affects ~30% of patients with HF risk factors, linking to larger atria and elevated NPs.
Why the study?
Congestion is a cardinal feature of untreated heart failure and might be detected by ultrasound before overt clinical signs appear.
What is the prevalence of subclinical congestion detected by ultrasound in patients at risk for heart failure, and how does it associate with clinical markers?

What is the prevalence of subclinical congestion detected by ultrasound in patients at risk for heart failure, and how does it associate with clinical markers?
Subclinical congestion detected by ultrasound is common (30%) in patients with heart failure risk factors and is associated with larger left atria and elevated natriuretic peptides.
No takes yet. Share an insight, caveat, or question.
Subclinical congestion may signal early risk in at-risk patients; leaves open whether ultrasound screening improves prevention.
Cuthbert et al. (2021) conducted a cross-sectional in Risk of developing heart failure (n=238). Ultrasound measures of congestion was evaluated on Prevalence of subclinical congestion (at least one positive ultrasound marker). Subclinical congestion detected by ultrasound was present in 30% of patients with clinical risk factors for heart failure and was associated with larger left atria and higher natriuretic peptides.
