Diagnostic value of Wells score and D-Dimer detection in acute pulmonary embolism / 实用医学杂志

ABSTRACT

Objective To assess the diagnostic value of Wells score and D-Dimer detection in acute pulmonary embolism. Methods Forty-two suspected cases of pulmonary embolism were collected from March 2012 to September 2014 Then Wells score and D-Dimer detection were applied to confirm the disease. Results Of the total, 26 patients were diagnosed by computed tomographic pulmonary arteriography (CTPA). There were 7, 24 and 11 suspected cases which had low, medium and high Wells score respectively. Among them, 1, 15, and 10 cases were diagnosed by CTPA. The diagnosis rates were 14.2% (1/7), 62.5% (15/24) and 90.9%(10/11) respectively. The D-Dimer level in pulmonary embolism group was significantly higher than that in non-embolism group(P < 0.01). The D-Dimer level of cases with medium or high Wells score was higher than those with low Wells score (P < 0.05). Conclusion Wells score combined with D-Dimer is convenient, accurate and safe for predicting acute pulmonary embolism.
