Abstract Background Heart Failure with Preserved Ejection Fraction (HFpEF) is a growing healthcare burden and its prevalence is increasing. Diagnosing HFpEF is challenging. Lung ultrasound (LUS) and left atrial strain are promising tools to assess pulmonary congestion and left atrial dysfunction in outpatient settings in patients with suspected HFpEF. Aim To evaluate the correlation of LUS B-lines with left atrial strain in patients with HFpEF. Methods Thirty-six consecutive patients (24 women, mean age 70±6 years) with clinical signs of heart failure were prospectively enrolled. Exclusion criteria were: ejection fraction <55%, more than mild mitral and/or aortic valve disease, pulmonary disease, pulmonary arterial hypertension. Within one hour all patients underwent comprehensive echocardiographic evaluation including left atrial strain analysis (peak atrial longitudinal strain-PALS), lung ultrasound assessment of B-lines on the antero-lateral and posterior chest wall, and NT-proBNP levels. Results The mean ejection fraction was 65.5±8.6%. In 28 patients (85%) a significant number of B-lines (≥15) was observed. We found a positive correlation between the number of B-lines and NT-proBNP levels (p<0.0001, r: 0.76, Figure 1.), left atrial volume (p<0.05, r: 0.45), and PALS (p<0.05, r: −0.5, Figure 2.). We didn't found any correlation between the number of B-lines and E/e'ratio (p=0.1, r: 0.28), or between E/e' ratio and NT-proBNP level (p=0.2, r: 0.2). Conclusion LUS is a simple, feasible tool to detect pulmonary congestion in HFpEF and it seems to better characterize these patients. B-lines correlate well with NT-proBNP values and with parameters of left atrial dysfunction. PALS is a promising too which better reflects pulmonary congestion and elevated NT-proBNP values than the conventional echocardiographic parameter E/e'.
