The extent of myocardial damage after heart attack can be determined by troponin level, electrocardiogram, echocardiogram and myocardial nuclear imaging.
1. Troponin: after myocardial infarction, troponin will be obviously elevated, which can estimate the extent of myocardial necrosis after infarction.
2. Electrocardiogram (ECG): In myocardial infarction, there will be obvious changes in ECG, such as elevation of ST segment upward, etc. ECG is in dynamic change after myocardial infarction, and it can be used as an aid to refer to the extent of myocardial necrosis.
3. Echocardiography: the degree of myocardial damage can be visualized in the examination, and the weakening or disappearance of ventricular wall motion written in the report at the end of the examination suggests that the myocardium is necrotic here.
4. Myocardial nuclear imaging: the degree of myocardial damage can be clearly understood through this examination.
In case of myocardial infarction, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable diagnosis and treatment.
