Abstract: Objective To investigate the clinical value of plasma BNP in predicting cardiovascular disease in patients with acute pulmonary embolism. Methods 97 cases of acute pulmonary thromboembolism diagnosed in our hospital from January to December 2017 were selected.The patients were divided into the observation group (21 cases) and control group (76 cases) according to whether there were cardiovascular complications.The differences and correlations of laboratory indexes between the two groups were compared, and the ROC curve was used to analyze the clinical value of BNP in predicting the occurrence of cardiovascular disease in patients with acute pulmonary embolism. Results 21 cases of cardiovascular complications occurred in the observation group, accounting for 21.65%.The concentration of BNP, Hs-CRP, TnI, AST, CK and DD in the observation group were (413.01±33.09) (pg/mL), (20.49±2.88) mg/L, (0.154±0.103) μg/L, (131.23±27.05) U/L, (421.64±50.70) U/L and (1.95±0.18) mg/L, which were higher than those of the control group(P<0.05). Spearman correlation analysis showed that plasma BNP levels were positively correlated with the levels of Hs-CRP, TnI, AST, CK and DD (r=0.802,0.718,0.683,0.705,0.753,P<0.05). The ROC curve analysis showed that the area of AUC of BNP was 0.834 (95%CI:0.795~0.935) of the highest, the sensitivity and specificity were 90.5% and 87.5% respectively. The area of combined diagnosis of AUC was 0.892 (95%CI:0.811~0.976),the sensitivity and specificity were 84.6% and 91.3%, respectively. Conclusion Plasma BNP is of high clinical value for predicting the incidence of cardiovascular disease in patients with acute pulmonary embolism. Multi-index combined examination may be more effective to detect the occurrence of cardiovascular disease.
