Do you need coronary angiography for myocardial infarction?

Whether to perform coronary angiography should take into account the patient's symptoms, test results, risk factors and overall health status. The doctor will fully communicate with the patient and develop an individualized treatment plan. Do patients with myocardial infarction need coronary angiography? Not necessarily. Whether to perform coronary angiography depends on the patient's specific conditions. The doctor will consider the patient's symptoms, ECG, myocardial enzymes and other test results, as well as the severity of coronary artery disease. The following are some factors to consider: 1. Symptoms: If the patient has typical chest pain symptoms that last for a long time and are highly suspected of myocardial infarction, coronary angiography may be necessary to determine whether there is stenosis or blockage in the coronary artery.2. ECG and myocardial enzymes: ECG examination may indicate changes in myocardial infarction, but sometimes the results may not be typical. Elevated myocardial enzymes also help diagnose myocardial infarction, but these test results may also be affected by other factors.3. Risk factors: age, sex, smoking history, hypertension, diabetes, hyperlipidemia and other cardiovascular disease risk factors are also one of the factors determining whether to perform coronary angiography. The doctor may order other tests, such as cardiac ultrasound, radionuclide myocardial perfusion imaging, etc., to assess heart function and the extent of myocardial infarction.5. Overall health status of the patient: Other health problems of the patient, such as renal insufficiency and lung disease, may also affect the feasibility and safety of coronary angiography. It should be noted that coronary angiography is an invasive examination method. Although it can provide detailed information about coronary artery lesions, it also has certain risks, such as bleeding and arrhythmia. Before deciding whether to perform coronary angiography, the doctor will fully communicate with the patient, analyze the risks and benefits of the examination, and formulate an individualized treatment plan according to the patient's condition. For some atypical patients with myocardial infarction or other suspicious situations, further examination or evaluation may be needed, such as coronary CT angiography, thrombolytic therapy for myocardial infarction, etc. The final treatment decision should be based on the patient's specific circumstances and the doctor's recommendations. Key information: Whether a patient with myocardial infarction needs coronary angiography should consider symptoms, test results, risk factors and the patient's overall health status. The doctor will fully communicate with the patient and develop an individualized treatment plan.
