Evaluation and analysis of abnormal ventricular wall motion after myocardial infarction by three-dimensional echocardiography combined with M-mode ultrasound
Objective:To evaluate the value of three-dimensional echocardiography(3DE)combined with M-mode ultrasound in the evaluation of ventricular wall motion abnormalities(RWMA)after myocardial infarction(MI).Methods:77 patients with MI admitted to our hospital from October 2022 to October 2023 were selected as the study objects.All patients underwent 3DE,M-mode ultrasound and coronary angiography(CAG)to examine the occurrence of RWMA.Using the results of CAG as the standard,the value and consistency with CAG results were compared with 3DE,M-mode ultrasound and 3DE combined M-mode ultrasound.Results:CAG results showed that 46 of 77 patients with MI had RWMA and 31 had non-RWMA.The sensitivity,accuracy and negative predictive value of RWMA after 3DE combined with M-mode ultrasonography were higher than those of 3DE and M-mode ultrasonography alone(P<0.05).There was a strong consistency between the CAG results and 3DE,or M-mode ultrasound,there was a stronger consistency between CAG results and 3DE combined M-mode ultrasound(P<0.05).Conclusion:Compared with 3DE or M-mode ultrasonography alone,3DE combined with M-mode ultrasonography is more valuable in assessing RWMA after MI.
