Diagnostic value of the non-invasive hemodynamic monitor system combine with the natriuretic peptide measurement in critical patients with dyspnea

Objective To investigate the diagnostic value of the natriuretic peptide measurement combine with non-invasive hemadynamic monitor system in critical patients with dyspnea.Methods 43 critical patients of with dyspnea were divided into groups according to differental clinical diasnosis,27 patients diagnisis cardiogenic dyspnea group(left and right heart failure groups) and non-cardiogenic dyspnea groups of 16 cases,those were meaured by the natriuretic peptide and monitored by non-invasive hemadynamic monitor system.Results The natriuretic peptide level of the patients whose dyspnea were caused by heart failure were obviously higher than those of patients whose dyspnea were caused by non-heart failure(P0.05).There was no statistical difference between dyspnea induced by left heart failure group and right heart failure group(P0.05).The Parameters such as cardiac output(CO),cardiac index(CI),strike volume(SV),strike index(SI),acceleration index(ACI) and left cardiac work index(LCWI)of heart failure group were significantly lower than the parameters of dyspnea induced by non-heart failure group(P0.05).But parameters of systemic circulation peripheral vascular resistance(SVR),pre-ejection period(PEP),systolic time rate(STR)of heart failure groups were significantly higher than the parameters of non-heart failure group(P0.05).Parameters heart rate(HR),thorax fluid capacity(TFC)of right heart failure group were significantly higher than the others(P0.05).There were no statistical differences in the heart rate(HR)and mean arterial pressure(MAP)between cardiogenic dyspnea groups and non-cardiogenic dyspnea group(P0.05).Conclusion The non-invasive hemadynamic monitor system combine with the natriuretic peptide provide reliable evidence for clinical diagnosis and treatment for critical patients with dyspnea.
