Abstract

Background: Acute heart failure (AHF) is a frequent cause of dyspnea, yet it remains difficult to diagnose. The diagnostic performance of lung ultrasonography in AHF is still being assessed; however, it represents a promising new point-of-care diagnostic technique. Aim and objectives: to evaluate the interrelation among sonographic B-Lines left ventricular function and Natriuretic Peptides in patients with acute onset class III-IV dyspnea. Subjects and methods: This observational study included 56 patients with acute onset dyspnea (NYHA) class III-IV and conducted at Emergency Department at Al-Hussein University Hospital. The populations were separated into two groups: Group 1 involved cases presented by dyspnea of acute onset with B lines detected by ultrasonography and Group 2 included patients presented by acute onset dyspnea without B lines and their serum B type Natriuretic Peptide (BNP) and Echocardiography assessed Result: There was significant lower EF and high serum pro BNP in the group with B-line than the group without B-line (P < 0.05). Conclusion: we concluded that there was a statistically significant higher NYHA grade IV in the group with B-line than the group without B-line (61.3% vs 28%). While no significant variation was found among groups concerning smoking, DM, HTN. The existence or absence of B-lines is a valuable tool for ruling in or out pulmonary congestion in acute setting, and there is proof of real-time matching of B-line quantity with fluctuation in EVLW and total body water. It offers additional predictive power to BNP.
