The purpose of this study is to explore the earlobe crease as a risk factor of acute myocardial infarction (AMI)in the Chinese population, combined with other risk factors, to predict high risk patients with coronary heart disease.
Primary objectives: Odds ratio and 95% confidence interval of binaural earlobe crease as risk factors of AMI.
Secondary objectives:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Initial AMI | To study the sensitivity, specificity, positive predictive value, and negative predictive value of different earlobe crease as risk factors of AMI |
| |
| No coronary heart disease | To study the characteristics of earlobe crease |

| Measure | Description | Time Frame |
|---|---|---|
| Odds ratio(OR，the ratio of the explosure number and non-explosure in case group/ the ratio of the explosure number and non-explosure in control group) and 95% confidence interval were calculated of binaural earlobe crease≥ 7 scores as risk factors of AMI | 3 years |
| Measure | Description | Time Frame |
|---|---|---|
| The score of the ELC in different gender of the patients with AMI. | 3 years | |
| The score of ELC in different age groups. | 3 years | |
| To compare the score of the ELC in acute ST elevation myocardial infarction and non ST elevation myocardial infarction. |

Inclusion Criteria:
Initial acute myocardial infarction(AMI).
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:
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.
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.
Signed informed consent.
