Abstract
The clinical value of cardiac color ultrasound and cardiac troponin T (cTnT) combined with dynamic electrocardiogram in evaluating the treatment effect on acute pulmonary embolism (APE) was investigated. Ninety-eight patients with APE treated in Jinan Zhangqiu District Hospital of TCM from March 2016 to February 2017 were selected, and they were examined via the cardiac color ultrasound, cTnT and dynamic electrocardiogram to evaluate the clinical value in the treatment of pulmonary embolism. Electrocardiogram showed that there was no significant difference in the poor prognosis rate between right ventricular strain group and non-right ventricular strain group (P>0.05); the poor prognosis rate in cTnT positive group was significantly higher than that in cTnT negative group (P<0.05). Moreover, the ultrasonic cardiogram revealed that the poor prognosis rate in right ventricular dysfunction group was significantly higher than that in non-right ventricular dysfunction group (P<0.05). It was found in the receiver operating characteristic (ROC) curve analysis that the areas under the curve (AUC) of ROC detected via cardiac color ultrasound and cTnT were >0.9, while that detected via dynamic electrocardiogram was <0.7. Besides, logistic regression analysis showed that cTnT and right ventricular dysfunction were the risk factors affecting the poor prognosis of patients with APE (P<0.05). In conclusion, cardiac color ultrasound can predict the prognosis of patients with APE through monitoring the right ventricular function; cTnT can also evaluate the prognosis of APE; but the electrocardiogram has little significance in evaluating the prognosis of APE.
