Segmental motion abnormalities of the left ventricular wall indicate segmental necrosis of the left ventricular wall myocardium, resulting in uncoordinated myocardial motion during systole and diastole. If the color echocardiogram shows abnormal segmental motion of the left ventricular wall, it suggests that the patient has had a recent or previous myocardial infarction. When a myocardial infarction occurs in the body, the localized myocardium becomes necrotic, resulting in decreased myocardial contractility. Due to the absence of motion, the amplitude of motion in these areas will be different from the rest of the normally exercising myocardium. If such segmental abnormal motion is present on cardiac color ultrasound, it may be an ultrasound manifestation of myocardial infarction. When this occurs, a history of myocardial infarction needs to be checked. It is also advisable to do coronary angiography to clarify the diagnosis. It is recommended to consult a doctor in time for relevant examination, and according to the specific situation, under the guidance of the doctor, carry out symptomatic treatment.
