| Popis: | 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 screening tools to assess pulmonary congestion and left atrial dysfunction in patients with suspected HFpEF. Aim To evaluate the relationship between LUS, left atrial strain and NT-proBNP level in patients with HFpEF. Also to assess the diagnostic power of B-lines in HFpEF population. Methods Forty-seven consecutive patients (24 women, mean age 69 ± 11 years) with clinical signs of heart failure were prospectively enrolled. Exclusion criteria were: ejection fraction Results In 34 patients (72%) a significant number of B-lines (≥15) were observed. We found a positive correlation between the number of B-lines and NT-proBNP levels (p Conclusion LUS is a simple, feasible tool to detect pulmonary congestion in HFpEF and it has a strong diagnostic power to predict elevated NTpro-BNP level. B-lines correlate with parameters of left atrial dysfunction. PALS is promising too, which better reflects pulmonary congestion and elevated NT-proBNP values than the conventional echocardiographic parameter E/e’. Abstract P1586 Figure.
