Pulmonary congestion assessed by lung ultrasound in stable ambulatory patients with heart failure and preserved ejection fraction in primary care

This study investigates the role of lung ultrasound in detecting subclinical pulmonary congestion in stable ambulatory patients with heart failure and preserved ejection fraction (HFpEF) managed in primary care. The authors found that a significant proportion of patients exhibited B-lines indicative of pulmonary congestion, which correlated with certain biomarkers and clinical signs, but not with functional capacity or quality of life measures. The findings suggest that lung ultrasound could be a valuable tool for identifying hidden congestion in this patient population.
