The purpose of this study is to describe the short-and long-tern (i.e. up to 2 years following the index event) AMPs in patients hospitalized for an acute coronary syndrome (i.e. STEMI or NSTE-ACS), and to document clinical outcomes, economic aspects and impact on quality of life of these AMPs in a 'real-life' setting.

Inclusion Criteria:

• Written informed consent has been provided.
• Diagnosis of STEMI, NSTEMI or UA
• Hospitalization for the first time within 48 hours of onset of symptoms.

Exclusion Criteria:

• UA, STEMI, NSTEMI precipitated by or as a complication of surgery, trauma, or GI bleeding or post-PCI UA, STEMI and NSTEMI occurring in patients already hospitalized for other reasons.
• Current participation in a randomised interventional clinical trial.

Asian patients hospitalized for ACS within 48 hours of symptom onset and who have a final diagnosis of unstable angina (UA), STEMI or non-ST-segment elevation myocardial infarction (NSTEMI).
