Heart attack review needs to check electrocardiogram, cardiac enzymes, cardiac ultrasound, blood, urine, stool routine, blood lipids, blood glucose, liver and kidney function, coagulation function, etc., and coronary angiography if necessary. 1. Electrocardiogram is simple and convenient, which can help the doctor to judge the infarction site in general, cardiac enzymes are important for judging the occurrence of reinfarction, and cardiac ultrasound can be a good way to know whether the heart valves are regurgitated stenosis or closure insufficiency, and also have a very good judgment of the endocardium redundant organisms. 2. Blood and urine routine is mainly to determine whether there is anemia, thrombocytopenia, gastrointestinal bleeding, urinary bleeding, proteinuria, etc. Lipid glucose is the monitoring and prevention of cardiovascular risk factors to assess the examination. 3. Liver and renal function can determine whether liver and renal insufficiency is caused by medication, which can help to adjust the dose of medication in time. Coronary angiography can be a good way to observe whether the cardiac vascular supply is stenotic and blocked. If severe stenosis occurs and leads to myocardial ischemia, stents need to be surgically placed to expand the stenotic coronary arteries in order to facilitate myocardial oxygen and nutrient supply, which is important in slowing down the ventricular remodeling of myocardial pathology. The specific tests that need to be used need to be analyzed according to the specific conditions of different patients, with a focus on the history of the use of different methods of examination, specific to the hospital doctors prescribed by the examination shall prevail.
