Acute non-ST-segment elevation myocardial infarction is a serious condition that is more likely to result in cardiogenic shock, arrhythmia, acute heart failure or even sudden death if timely intervention is not made.
Acute non-ST-segment elevation myocardial infarction is a disease of myocardial ischemia or myocardial necrosis due to rupture of unstable arterial plaque resulting in coronary constriction and embolism.
Advanced age, smoking, a history of hypertension, and a history of diabetes mellitus are well-characterized risk factors for this disease. The main predisposing causes include infection, arrhythmia, and anemia. Clinical manifestations often include retrosternal pressure-like pain, which often persists unrelieved and sometimes radiates to the left shoulder and jaw. Electrocardiogram and myocardial markers help to diagnose the disease.
Since acute non-ST-segment elevation myocardial infarction is potentially harmful and prone to cardiogenic shock, arrhythmia, recurrent myocardial infarction, acute heart failure, and even sudden death, the patient should be put on bed rest immediately, and a risk assessment should be made for the patient.
Anti ischemic therapy (e.g. nitroglycerin), antiplatelet therapy (e.g. aspirin), anticoagulant therapy (e.g. low molecular heparin), and lipid-lowering therapy should be given under the guidance of specialized doctors, and invasive therapy can be given to patients with more serious conditions in a timely manner.
When chest pain or other cardiac discomfort occurs, prompt medical attention should be sought to avoid delaying optimal treatment.
