Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This was a retrospective study using the Taiwan's National Health Insurance Research Database (NHIRD). The study employed two study designs for different purposes as follows:

* A cross-sectional analysis was conducted to explore the annual incidence trends.
* A longitudinal cohort study was conducted to assess baseline characteristics, treatment patterns, long-term healthcare utilization, and cause-specific mortality among incident AMI patients.

In each part, the study was conducted for AMI, and separately for ST-segment elevation and non-ST- segment elevation myocardial infarction (STEMI and NSTEMI)

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Cross-sectional analysis:

* Patients aged 20 years and older.
* Patients who had been admitted for AMI, defined as primary or first secondary diagnosis of AMI between 2014 and 2020.
* The diagnosis of AMI/ STEMI/ NSTEMI was identified by the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes and 10th revision (ICD-10-CM) codes.
* Incident cases of AMI hospitalization were defined as no history of AMI-related hospitalization or outpatient visit within 1 year before admission.

Longitudinal analysis:

Patients aged 20 years and older.

* Patients who had been admitted for AMI, defined as primary or first secondary diagnosis of AMI between 2014 and 2017.
* The diagnosis of AMI/ STEMI/ NSTEMI was identified by ICD-9-CM codes and ICD-10-CM codes. (The ICD-9-CM code and ICD-10-CM codes were the same as above)
* Incident cases of AMI hospitalization were defined as no history of AMI-related hospitalization or outpatient visit within 1 year before admission.
* The cohort entry date was defined as the admission date of incident AMI hospitalization, and the index date was defined as the discharge date of incident hospitalization.
