ABSTRACT
Objective To evaluate the clinical value of CT angiography (CTA) in the diagnosis of acute pulmonary embolism (APE) after standardized chest pain assessment in patients with acute chest pain.Methods From January 2014 to May 2016,The clinical data of 43 patients with acute chest pain in Wuzhou Hospital of Traditional Chinese Medicine and Wuzhou Worker's Hospital received CTA examination were retrospectively analyzed.After standardized assessment,16 patients with suspected APE through pulmonary artery CTA scan screening were selected as observation group.27 cases of chest pain who were not received standardized assessment were selected as the control group,the chest CTA scan was used to investigate the causes of chest pain.The number of CTA confirmed by APE in two groups was compared.The effect of APE screening scale score and D-Dimer on the diagnosis of APE in the observation group was analyzed,and the application value of standardized evaluation of chest pain in APE was analyzed.Results The positive rate of CTA in the observation group was higher than that in the control group,and the difference between the two groups was statistically significant(x2 =3.93,P ＜ 0.05).The APE screening scale and D-Dimer in the observation group were (9.64 ±4.74) points and (886.73 ± 191.83) μg/L,respectively.which in the APE excluded patients were (2.20 ± 1.64) points,(587.20 ± 35.79) μg/L,respectively,the differences were statistically significant(t =3.363,3.402,all P ＜ 0.01).Conclusion Patients with acute chest pain and chest pain are standardized after the evaluation,optimization of CTA examination and improve the diagnostic rate of APE,reduce the rate of misdiagnosis and missed diagnosis,provide timely and accurate diagnostic basis for clinicians to gain valuable opportunity for further disposal.
