473 LUNG ULTRASOUND IN CORONARY CARE UNIT, AN IMPORTANT DIAGNOSTIC TOOL FOR CONCOMITANT PNEUMONIA

Abstract Background In the setting of coronary care unit (CCU), early detection pneumonia is para-mount important to prevent severe complications. This study was designed aiming evaluate diagnostic accuracy lung ultrasound (LUS) in and compared with chest x-ray (CXR). Method We enrolled 110 consecutive patients admitted CCU Federico II University Hospital. Each patient underwent CXR bedside LUS on admission. The final diagnosis (pneumonia vs no-pneumonia) established by another clinician reviewing clinical laboratory data independent results possibly prescribing contrast-enhanced CT (n=34). Results Mean age 70 ± 11 years old, 68% males. Pneumonia clinically 26 (23%) patients. positive for 24 (sensitivity 92% specificity 81%). Chest radiography 9 43% 95%). Using scan as referee exhibit sensibility a 96%. ROC curve analysis 0.86 (95% CI 0.77-0.94), higher than 0.68 0.55-0.84), p<0.05 (Figure). Conclusion Based findings present study, significantly x-ray, comparable scan.
