Ultrasound lung comets (ULCs) are a sign of extravascular lung water and useful for diagnosis of heart failure. However, it is not known whether ULCs can be assessed in sitting outpatients by a pocket-sized ultrasound device (PSU). The aim of this study is to evaluate the accuracy of ULCs in a sitting position for diagnosis of heart failure with reference to serum brain natriuretic peptide (BNP) levels.
One hundred and seven consecutive patients with known or suspected cardiovascular disease were examined by a PSU (Vscan: GE medical systems). The ULC score was the sum of the points where ULC was observed among a total of 10 points on the chest wall. Serum BNP levels was measured on the same day.
Heart failure was confirmed in 14 patients and ruled-out in 93 based on the Framingham criteria. The ULC scores and Serum BNP levels showed significant positive correlation (r= 0.68, P<0.01). The receiver operating characteristic analysis showed an area under the curveof 0.896 for ULCs and 0.872 for BNP in diagnosis of heart failure.
The ULCs evaluated in the sitting outpatients by PSU could be a surrogate of serum BNP levels and offer an useful tool for diagnosis of heart failure in the clinic.
