Comparison of Beside Chest Tissue Ultrasound Versus BNP in Diagnosis of Acute Heart Failure in ED

Abstract

Congestive heart failure is a heart failure which results in pulmonary congestion and ultimately pulmonary edema, which, despite recent therapeutic advances, is still a progressive, high mortality syndrome that has increased in recent decades. In the past two decades, pulmonary ultrasound has been identified as an effective tool for the investigation of acute shortness of breath that is used to differentiate between acute heart failure and non-cardiac causes of acute dyspnea. Therefore, this study compared the findings of ultrasound of the lung In patients with acute heart failure with BNP in patients referred to the emergency department of the hospital M. Reza (AS) was Tabriz. Materials and Methods: This study was performed in Emergency Medical Center of Imam Reza (AS) in Tabriz in 1393-1393. For patients entering the emergency room after a history, both the Golden Standard Test (BNP) and the lung ultrasound were performed. To ensure Blinding ultrasound, ultrasound was performed simultaneously with blood sampling and the ultrasound did not reveal the BNP result before it was performed. When ultrasound is performed in the presence of multiple B-lines at least 3 mm apart, a diagnosis of pulmonary edema for heart failure was suggested for the patient. Results: The number of participants in this study was 108, of which 54.6% were men and 45.4% women. Correlation coefficient between width and number of kerley lines was 0.79, correlation coefficient between NT.ProBNP and width of kerley lines was 0.65, and the correlation coefficient between NT.ProBNP and number of kerley lines was 0.77, which indicates a positive correlation (p = 0.00) The level below the rock chart related to the prediction of mortality was 0.84 with a width of 0.84, with a sensitivity of 78% and 82%, respectively. The level below the rock chart is also related to the prediction of mortality by the variable number of flax lines equal to 0.84 with a sensitivity of 77% and 69%, and the following level of the graph of the NT.ProBNP variable is 0.78 with a sensitivity of 72% and 77% Came out.
