Inclusion criteria
Inclusion criteria: 1. Signed and dated informed consent form; 2. Commitment to follow the research procedures and cooperate throughout the entire study; 3. Age between 18 and 80; 4. Meet the diagnosis criteria for acute myocardial infarction: (1) Ischemic chest pain lasting >= 30 minutes; (2) Dynamic changes in ECG: ST-segment elevation myocardial infarction (STEMI): ST-segment elevation in 2 adjacent leads (V2-V3 >= 0.2 mV, other leads >= 0.1 mV); Non-ST-segment elevation myocardial infarction (NSTEMI): ST-segment depression >= 0.1 mV or T-wave inversion, positive troponin; (3) Elevated markers of myocardial injury: high-sensitivity troponin (hs-cTn) > 99th percentile of normal reference value; CK-MB >= 2 times the normal value; time from symptom onset to admission = 2 minutes overnight; (2) No ventricular tachycardia; (3) Occasional atrial or ventricular premature beats are allowed.
Exclusion criteria
Exclusion criteria: 1.Participants were excluded if they met any of the following criteria: (1) severe skin disease, allergic predisposition, or chest/back skin damage or infection that prevented proper placement of Holter electrodes or contact with the mattress; 2. known persistent arrhythmias, such as permanent atrial fibrillation or the presence of a cardiac pacemaker, which could confound the interpretation of the reference standard; 3.poor compliance, as determined by the study investigators, that might compromise completion of the study protocol; 4. any other circumstances that, in the investigators' judgment, rendered the participant inappropriate for study participation.
