Abstract:
Objective: To explore the clinical value of N-terminal Pro-brain natriuretic peptide (NT-ProBNP) and cardial troponin I (cTnI) for evaluating the patients with acute pulmonary embolism (APE) combining right ventricular dysfunction (RVD). Methods: A total 92 APE patients treated in our hospital were studied. The blood levels of NT-ProBNP and cTnI were measured on next morning of administration and echocardiography was performed within 24 hours of APE diagnosis. According to echocardiographic results, the patients were divided into 2 groups: APE with RVD group,n=47 and APE without RVD group,n=45. Blood levels of NT-ProBNP and cTnI were compared between 2 groups. Results: Compared with APE without RVD group, APE with RVD group presented increased levels of NT-ProBNP, cTnI and right ventricular end-diastolic diameter (RVEDD), allP<0.01. ROC curve analysis found that both AUC of NT-ProBNP and cTnI > 90%, the optimum operating point for NT-ProBNP and cTnI were 554 pg/ml and 0.09 ng/ml respectively. Logistic regression analysis showed that NT-ProBNP (r=1.227,P=0.005), cTnI (r=0.862,P=0.016), right ventricular dysfunction (r=0.936,P=0.008) and heart rate (r=0.809,P=0.023) were related to poor prognosis for in-hospital patients. Conclusion: Blood levels of NT-ProBNP and cTnI may help diagnosing the patients with acute pulmonary embolism with right ventricular dysfunction, it may also predict the short term prognosis in clinical practice.
