Diagnosis Value And Volume Status Assessment Of Ultrasound Internal Jugular Vein Cross-sectional Area Measured For Heart Failure With Dyspnea In ED

Background:Accurately diagnosing congestive heart failure(CHF)in patients with dyspnea in ED.It is very difficult according toclinical history and physical examination,it may often nondiagnostic and may beinaccurate,especially when patients have complicated comorbid conditions.Objective:To investigate diagnosis value oflJARsin patients withdyspneain emergency department in patients with dyspnea(cardiac dyspnea or pulmonary dyspnea).Measurements:47 patients with dyspneaweremeasured concentration of IJARs,BNP,Left Ventricular End diastolic Volume,left ventricular ejection fraction(EF).Congestive heart failure by C-ECHO was determined bythe final reading of board-certified cardiologists blinded to the results of JVD-US and all clinical data,including BNP.Results:Internal jugular vein cross-sectional area(IJARs)and BNP correlation,r value was 0.696(p<0.001),with statistical significance,IJARs and LVEDV correlation,r value 0.415(p<0.05),with statistical significance,IJARs and CVP correlation,r value 0.275(p>0.05)with weak correlation.Using ROC curve analysis of IJARs)to predict cardiac dyspnea,as shown in the figure below as a result,the area under the curve is 0.869(p<0.05)and 95%confidence interal CI,0.761-0.976,Cut-off a value of 44.51.Joint IJARs and BNP predicts cardiac dyspnea IJARs using ROC curve analysis and BNP predicts cardiac dyspnea,the results of the diagram below,the area under the curve is 0.789(p<0.05)and 95%confidence interal,0.652-0.926,the sensitivity of prediction is 0.800,specific degree is 0.778,positive likelihood ratio is 3.604,the negative likelihood ratio is 0.257.Conclusion:Internal jugular vein cross-sectional are(IJARs)measurement can be a important tool for diagnosingdyspnea in ED.
