Abstract:
Objective:To explore the relationship among clinical manifestations ,SⅠ QⅢ TⅢ feature of ECG ,plasma level of D‐dimer (DD) and diagnosis of pulmonary embolism (PE) .Methods :Clinical data of 212 inpatients ,who received pulmonary CT angiography (CTA) in our hospital from Jun 2012 to May 2014 ,were retrospectively ana‐lyzed .According to pulmonary CTA results ,patients were divided into PE group (n=56) and non‐PE group (n=156) .Basic hospitalization data ,including clinical manifestations ,ECG features and plasma DD level ,were collect‐ed and compared between two groups .Results:Compared with non‐PE group ,there were significant rise in percent‐ages of dyspnea (44.87% vs .75% ) and prolonged bedridden time (3.85% vs .14.29% ) ,significant reduction in percentage of no clinical manifestations (38.46% vs .3.57% ) in PE group , P<0.01 all .Percentage of ECG SⅠQⅢTⅢ feature in PE group was significantly higher than that of non‐PE group (50% vs .23.08% ) , P<0.01. Compared with non‐PE group ,percentage of plasma DD>10μg/ml significantly rose (19.23% vs .32.14% ) in PE group ,P<0.05 .Conclusion:Patients with dyspnea and/or prolonged bedridden time ,that cannot be explained by other car‐diopulmonary diseases ,and SⅠ QⅢ TⅢ feature of ECG ;plasma DD level significant rising (> 10 μg/ml) should be considered to be PE .
