Brief Summary
Multicenter post-approval observational retrospective cohort study in routine clinical practice (Real World Evidence Study) to assess the 1-year safety profile associated with ticagrelor and clopidogrel therapy in a contemporary reprospective cohort of patients who survived the initial 30-day period after the index hospitalization for acute coronary syndrome (ACS).

Clopidogrel
Clopidogrel is a prodrug that requires metabolic activation in two stepsby hepatic CYP450 enzymes to produce the active metabolite that inhibits platelet aggregation. The active metabolite of clopidogrel selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet P2Y12 receptor and the subsequent ADP-mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet aggregation. Consequently, due to the irreversible binding to the P2Y12 receptor,platelets exposed to clopidogrel's active metabolite are affected for the remainder of their lifespan (about 7 to 10 days) and recovery of normal platelet function occurs at a rate consistent with the normal platelet turnover. Clopidogrel was approved by the European Commission on 15 July 1998 for the secondary prevention of atherothrombotic events in adult patients with ACS.
Ticagrelor
Ticagrelor is a nucleoside analogue member of the chemical class cyclopentyltriazolopyrimidines (CPTP), which is a selective and reversible ADP- receptor antagonist acting on the platelet P2Y12 receptor. This prevents the binding of ADP to the receptor which attenuates plateletactivation and aggregation.The drug was approved by the European Commission on December 3, 2010, for the prevention of thrombotic events (cardiovascular death, myocardial infarction and stroke) in patients with ACS (unstable angina, non ST elevation Myocardial Infarction \[NSTEMI\] or ST elevation Myocardial Infarction \[STEMI\]) including patients managed medically, and those who are managed with percutaneous coronary intervention (PCI) or coronary artery by-pass grafting (CABG).
Interventions
Describe the safety of Ticagrelor vs Clopidogrel use, in patients with ACS in terms of major bleeding between 30 days and one year after the index ACS event. An ITT approach and IPCW method to adjust for change of initial treatment will be used for the analysis.

Eligibility Criteria
Patients with ACS in a real world setting
You may qualify if:
- All-comers ACS population (with or without ST segment elevation, including unstable angina) with:
- A recent CCU admission (patients included in the ARIAM-CREA study within 1 week from the index ACS admission between March 1, 2015 to March 31, 2018), irrespective of either the initial management (invasive or non-invasive) or the revascularization procedure (PCI with stenting or CABG) discharged on DAPT including either Ticagrelor or Clopidogrel and have survived the first 30-day follow-up period from the index ACS event and could complete a 12-month follow-up.
You may not qualify if:
- Age \< 18 years.
- Subjects who died in the first 30-day follow-up period from the index ACS event, including those who died during the index admission.
- A medical condition likely to limit survival to less than 1 year.
- Any factors judged by the local investigators to be likely to limit adherence to pharmacological treatment.
- Failure to obtain informed consent from participant.
- Currently enrolled in an interventional clinical research trial involving an investigational product (drug) or device
- Not available for follow-up over a minimum of 365 days, e.g. no fixed home address.
- Non-ACS diagnosis at discharge, i.e., acute myocarditis, Takotsubo syndrome, pulmonary thromboembolism or acute aortic syndromes.
- Myocardial infarction secondary to an ischaemic imbalance or type 2 myocardial infarction (Third Universal Definition of MI), in instances of myocardial injury with necrosis, where a condition other than CAD contributes to an imbalance between myocardial oxygen supply and/or demand, i.e., anaemia, sepsis, tachyarrhythmias, hypotension, heart failure…
- Patients not discharged on dual antiplatelet therapy (DAPT) consistent on low dose of ASA plus a P2Y12platelet receptor inhibitor (Clopidogrel or Ticagrelor)
- Patient discharged on DAPT including Prasugrel as the P2Y12 inhibitor drug.
- Hypersensitivity to ticagrelor or any of the excipients.
- Active pathological bleeding.
- History of intracranial haemorrhage (ICH).
- Severe hepatic impairment.
