Objective To investigate the clinical values of etiological diagnosis by testing cardiac index CI and total peripheral resistance index TPRI using bioreactance noninvasive cardiac output monitoring NICOM in patients with dyspnea. Methods Prospective,observational study was taken in 113 adult patients admitted with dyspnea or acute exacerbation of dyspnea in stable disease. The patients were divided into two groups namely heart failure group （n=55）and non-heart failure group（n=58） according to the guidelines on the diagnosis and treatment of acute heart failure（2010） as the standard criterion. All patients underwent CI and TPRI test by using NICOM. Receiver operating characteristic curve（ROC curve） was plotted to evaluate the diagnostic value of CI and TPRI. Results Compared with non-heart failure group,the CI was worse（P<0.001）,and the TPRI was elevated（P<0.001）. ROC curve showed that the area under the curve（AUC） of CI was 0.792（95%CI：0.708~0.875,P=0.000）. The cut-off of CI was 2.65L/min/m²,the sensitivity was 63.6%,and specificity was 87.9%. The AUC of TPRI was 0.733（95%CI：0.641~0.825,P=0.000）. The cut-off of CI was 2 353dynes.sec/cm⁵/m²,the sensitivity was 72.7%,and specificity was 67.2%. The sensitivity of CI combined TPRI was 80%,and specificity was 65.5%. Conclusion NICOM monitoring CI have high specificity,and combined TPRI monitored may improve sensitivity for dyspnea caused by heart failure.
