Background:No convenient,inexpensive,and non-invasive screening tools exist to identify pulmonary hyperten-sion(PH)-left heart disease(LHD)patients during the early stages of the disease course.This study investigated whether different methods of lung ultrasound(LUS)could be used for the initial investigation of PH-LHD.Methods:This was a single-center prospective observational study which was performed in the Zigong Fourth People's Hospital.We consecutively enrolled patients with heart failure(HF)admitted to the emergency intensive care unit from January 2018 to May 2020.Transthoracic echocardiography and LUS were performed within 24 h before discharge.We used the Spearman coefficient for correlation analysis between ultrasound scores and pulmonary arterial systolic pressure(PASP).Bland-Altman plots were generated to inspect possible bias,and receiver operating characteristic(ROC)curves were calculated to assess the relationship between ultrasound scores and an intermediate and high echocardiographic probability of PH-LHD.Results:Seventy-one patients were enrolled in this study,with an overall median age of 79(interquartile range:71.5-84.0)years.Among the 71 patients,36(50.7％)cases were male,and 26(36.6％)had an intermediate and high echocardiographic probability of PH.All four LUS scores in patients with an intermediate and high probability of PH were significantly higher than in patients with a low probability of PH(P＜0.05).The corre-lation coefficient(r)between different LUS scoring methods and PASP was moderate for the 6-zone(r=0.455,P＜0.001),8-zone(r=0.385,P=0.001),12-zone(r=0.587,P＜0.001),and 28-zone(r=0.535,P＜0.001)methods.In Bland-Altman plots,each of the four LUS scoring methods had a good agreement with PASP(P＜0.001).The 8-zone and 12-zone methods showed moderately accurate discriminative values in differentiating patients with an intermediate and high echocardiographic probability of PH(P＜0.05).Conclusions:LUS is a readily available,inexpensive,and risk-free method that moderately correlates with PASP.LUS is a potential screening tool used for the initial investigation of PH-LHD,especially in emergencies or critical care settings.
