Earlobe Creases Predict Prognosis in Chinese Patients With Acute Myocardial Infarction
Earlobe Creases Predict Prognosis in Chinese Patients With Acute Myocardial Infarction
To investigate the feasibility of the earlobe crease as an early prognostic predictor for
 acute myocardial infarction(AMI) in Chinese population.
Primary Objective : 1 year primary composite end point (including the whole death, recurrent
 myocardial infarction, stroke, target vessel revascularization, stent thrombosis) in AMI
 patients with different types of earlobe crease.

 Secondary objective:

 1. The incidence of complications during hospitalization

 2. The rate of rehospitalization due to cardiovascular disease

 3. The incidence of revascularization at 1 year after AMI
Inclusion Criteria:

 1. Initial acute myocardial infarction(AMI)

 2. Detection of a rise and/or fall of cardiac biomarker values (preferably cardiac
 troponin (cTn) with at least one value above the 99th percentile upper reference limit
 (URL)) and with at least one of the following:

 -  Symptoms of ischemia

 -  Development of pathologic Q waves in the electrocardiogram (ECG)

 -  New or presumed new significant ST-segment-T wave (ST-T) changes or new left
 bundle branch block (LBBB).

 -  Identification of an intracoronary thrombus by angiography or autopsy

 -  Imaging evidence of new loss of viable myocardium or a new regional wall motion
 abnormality.

 3. Type 1 (spontaneous myocardial infarction(MI)) in the third universal definition of
 MI: MI consequent to a pathologic process in the wall of the coronary artery (eg,
 plaque erosion/rupture, fissuring, or dissection), resulting in intraluminal thrombus.

 4. Infarct related artery (IRA) showed that acute thrombus formation, IRA occlusion or
 stenosis ≥95%、≥90%～95%、≤90%，thrombolysis in myocardial infarction (TIMI)0-3 flow.

 5. PCI(percutaneous coronary intervention)intervention（PCI for STEMI within 12 hours
 after symptom onset）.

 6. Signed informed consent.

 Exclusion Criteria:

 1. Combined valvular heart disease, cardiomyopathy, blood diseases, skin diseases,
 rheumatic diseases, ischemic cerebrovascular disease, tumor, etc.

 2. Previous myocardial infarction.

 3. Previous PCI and coronary artery bypass graft(CABG).

 4. Chronic total occlusion(CTO)lesions.

 5. Ear malformation.

 6. Ocular diseases.

 7. Participating in a clinical study.
