Inclusion criteria

Inclusion criteria: The diagnosis of non-ST-segment elevation myocardial infarction (NSTEMI) is based on the Chinese Expert Consensus on the Diagnosis and Treatment of Myocardial Infarction: (1) A 12-lead electrocardiogram (ECG) at admission shows new or transient ST-segment depression >=0.1 mV or T-wave inversion >=0.2 mV in two or more contiguous leads; (2) The patient exhibits typical clinical symptoms of ischemic heart disease; (3) Elevated or dynamically changing biomarkers such as cardiac troponin, with at least one value above the 99th percentile upper reference limit; (4) A GRACE risk score indicating intermediate to low risk (less than 140 points).

Exclusion criteria

Exclusion criteria: (1) Severe valvular heart disease; (2) Atrial fibrillation (with heart rate exceeding 100 beats per minute); (3) Pericarditis and massive pericardial effusion; (4) Complete bundle branch block observed on electrocardiogram (ECG) at admission and/or during hospitalization; (5) Poor-quality echocardiographic images that preclude effective analysis.
