The Management Of Echocardiography For Risk Stratification Of Acute Pulmonary Embolism And Its Clinical Value

Objectives 1 To application two-dimensional echocardiography, three-dimensional echocardiography and tissue Doppler imaging evaluation in patients with acute pulmonary embolism and the risk group of right ventricular function. To observe the right ventricular function changes for the risk group of APE patients. 2 To evaluate the risk group of APE patients in the conventional echocardiographic measurements and the biological markers and the RT-3DE values of the patients and analysis of the correlation among them.Methods Selected from June 2014 to August 2015 in Tangshan worker hospital treatment by CT pulmonary angiography(CTPA) diagnosis of APE patients in 120 cases, of which 58 cases of male, 62 cases of female, aged from36- 78 years old, average(56.5 ~ 14.5) years old. According to ESC conference of 2014 released the 3rd edition of the acute pulmonary embolism diagnosis and treatment guidelines for patients with ape were risk stratification, patients were classified as low risk group(38 cases), medium and low risk group(34 cases), middle and high risk group(27 cases) and high risk group(21 cases) groups. All subjects from 2DE, TDI and RT-3DE examination and laboratory tests, measuring the index of routine ultrasound for right heart, right ventricular ejection fraction, right ventricular end diastolic volume, right ventricular end systolic volume, right ventricular stroke output. The relationship and clinical value of c Tn I, BNP, D- two levels and blood gas analysis and risk stratification in patients with APE were examined and analyzed.Results 1 The low risk group, medium and low risk group, middle and high risk group and high risk group groups with acute pulmonary embolism of Em and Em / Am differences has statistical significance(P<0.01), the differences between the four groups Am no statistical significance(P>0.01). 2 The low risk group, medium and low risk group, middle and high risk group and high risk group with acute pulmonary embolism of RVEDV, RVESV and RVEF were all statistically significant(P<0.01); RVSV of each group had no statistical significance(P > 0.01). 3 The levels of BNP, CTn I and D- two levels in all the risk groups with acute pulmonary embolism, the difference was statistically significant(P<0.01).Conclusions Echocardiography can be noninvasive, accurate and sensitive in evaluating the changes of right ventricular function in the risk groups of APE, and provide objective evidence for clinical judgment of the severity of APE. 2 With the risk degree of APE patients increased, RVEDV and RVESV were gradually increased, RVEF was gradually decreased, and no significant change in RVSV. 3 To evaluate the correlation among the APE values and the biological markers and the RT-3DE values of the patients in each group.
