Three-Dimensional Echocardiography and Coagulation Function Detection in the Prognosis Evaluation of Patients with Acute Myocardial Infarction

Abstract

This research was aimed at discussing the application value of coagulation function detection and three-dimensional echocardiography in the prognosis evaluation of acute myocardial infarction (AMI) patients. 72 patients with AMI were divided into the recovered group (good recovery) and unrecovered group (poor recovery) according to the results of postoperative ultrasonography. The left ventricular parameters of the patients were detected by three-dimensional ultrasound, and the coagulation function was also detected. The results showed that 3 months after surgery, the regional end-systolic volume (rESV) and regional end-diastolic volume (rEDV) of the left ventricle in the patients were smaller than the measured values 1 week after surgery. The left ventricular regional ejection fraction (rEF) was greater than the value measured 1 week after surgery, and all the differences were statistically significant ( $P<0.05$ ). For the end-systolic volume (ESV), end-diastolic volume (EDV), and ejection fraction (EF) (%), the two-dimensional ultrasound results were significantly lower than the three-dimensional ultrasound results, and there were significant differences ( $P<0.05$ ). Tmsvle6-Dif% of the recovered patients was $14.99\pm 9.88$ and $14.37\pm 9.78$ 3 months and 6 months after surgery, respectively. These were smaller than $30.91\pm 18.63$ and $33.51\pm 17.96$ of the unrecovered patients; the differences were of statistical significance ( $P<0.05$ ). Tmsvl6-SD% of recovered patients was $3.69\pm 2.47$ and $3.61\pm 1.83$ 3 months and 6 months after surgery, respectively, which were also smaller than $7.38\pm 4.06$ and $7.96\pm 2.82$ of unrecovered patients, showing statistically significant difference ( $P<0.05$ ). The postoperative Tmsvle6-Dif% and Tmsvl6-SD% of the recovered group were lower than those of the unrecovered patients, with the statistically significant differences ( $P<0.05$ ). The level of coagulation factors in the recovered group was also significantly lower than that in the unrecovered group with the difference statistically significant ( $P<0.05$ ). The results suggested that three-dimensional echocardiography played an important role in the evaluation of cardiac conditions in AMI patients. The level of coagulation factors varied with the AMI condition of patients, and there was an obvious relationship between them, which could provide a reference value for the prognosis evaluation of patients.
