Prognostic value of lung ultrasound in chronic stable ambulatory heart failure patients

Abstract:

Introduction and objectives The role of lung ultrasound (LUS) in acute heart failure (HF) has been widely studied, but little is known about its usefulness in chronic HF. This study assessed the prognostic value of LUS in a cohort of chronic HF stable ambulatory patients. Methods We included consecutive outpatients who attended a scheduled follow-up visit in a HF clinic. LUS was performed in situ. The operators were blinded to clinical data and examined 8 thoracic areas. The sum of B-lines across all lung zones and the quartiles of this addition were used for the analyses. Linear regression and Cox regression analyses were performed. The main clinical outcomes were a composite of all-cause death or hospitalization for HF and mortality from any cause. Results A total of 577 individuals were included (72% men; 69 ± 12 years). The mean number of B-lines was 5 ± 6. During a mean follow-up of 31 ± 7 months, 157 …
