Acute non-ST-segment elevation myocardial infarction does not necessarily require stent implantation, and the treatment plan can be based on the results of coronary angiography, which can be conservative or coronary artery bypass grafting.
Acute non-ST-segment elevation myocardial infarction generally requires routine coronary angiography to understand the severity of the patient’s coronary artery lesions and to determine the next step in the treatment plan.
Some patients may not have particularly severe stenosis and may have coronary artery spasm, which may not meet the criteria for stent implantation, and may be treated with aspirin, atorvastatin, isosorbide nitrate, and other medications.
Patients with limited stenosis of the coronary arteries can have their blood supply improved by implantation of a stent to alleviate the patient’s symptoms and reduce myocardial necrosis.
Patients with diffuse stenosis of the coronary arteries, such as severe three-branch lesions of the coronary arteries, usually cannot be effectively improved by implanting a stent, and coronary artery bypass grafting treatment is needed.
Patients with non-ST-segment elevation myocardial infarction should undergo relevant investigations and treatments under the supervision of a cardiologist and decide on the next treatment plan.
