Non-ST-segment elevation acute coronary syndromes are life-threatening disorders, usually caused by acute coronary thrombosis and subsequent myocardial ischaemia, presenting without persistent ST-segment elevation in the initial electrocardiogram. According to the occurrence of myocardial necrosis, non-ST-segment elevation acute coronary syndromes are divided into non-ST-segment myocardial infarction or unstable angina. The management of non-ST-segment elevation acute coronary syndromes requires an early diagnosis and risk stratification, urgent hospitalization, monitoring, and medical treatment, including antithrombotic therapy with dual antiplatelet therapy (aspirin plus one P2Y12 inhibitor) and parenteral anticoagulation, anti-ischaemic treatment, and preventative therapies. After the initial medical therapy is established, an invasive strategy, consisting of coronary angiography with coronary revascularization (either percutaneous coronary intervention or coronary bypass graft surgery), as appropriate, should be decided. The timing of the invasive strategy should be adjusted, according to the patient’s risk. Given the high event rate of patients with non-ST-segment elevation acute coronary syndromes after hospital discharge, an aggressive long-term preventative therapy should be put in place to improve prognosis.
