【摘要】 目的:探讨临床表现、心电图SⅠQⅢTⅢ特征、血浆D-二聚体(DD)水平与肺栓塞(PE)诊断的关系。方法:回顾性分析我院2012年6月至2014年5月进行肺动脉CT血管成像(CTA)的212例住院患者的临床资料。根据肺动脉CTA检查结果,患者被分为PE组(56例)和无PE组(156例)。收集患者住院基本资料,包括临床表现、ECG特征及血浆DD水平,并在两组间进行比较。结果:与无PE组比较,PE组呼吸困难(44.87%比75%),长期卧床(3.85%比14.29%)患者比例显著升高,无临床表现比例显著降低(38.46%比3.57%),P均<0.01。PE组ECG具有SⅠQⅢTⅢ特征的患者比例显著高于无PE组(50%比23.08%),P<0.01。与无PE组比较,PE组血浆DD>10μg/ml比例显著升高(19.23%比32.14%),P<0.05。结论:临床症状有呼吸困难和/或长期卧床者,出现其他心肺疾患不能解释的临床表现时;ECG具有SⅠQⅢTⅢ特征;DD明显升高(>10μg/ml)者应考虑肺栓塞的可能性。更多还原

【Abstract】 Objective:To explore the relationship among clinical manifestations,SⅠ QⅢTⅢ 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 analyzed.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 collected and compared between two groups.Results:Compared with non-PE group,there were significant rise in percentages 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 SⅠQⅢTⅢfeature 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 cardiopulmonary diseases,and SⅠQⅢ TⅢfeature of ECG;plasma DD level significant rising(>10μg/ml)should be considered to be PE.更多还原
