Myocardial Infarction (MI) Clinical Trial
Official title:
An Observational, Register-based Study on Ticagrelor 60 mg Persistence and Event Rates in Clinical Practice in the US and Europe.
This is an observational study based on secondary data extracted from multiple register-based data sources in the US and Europe (Sweden, United Kingdom, Italy, Germany). The study will include patients initiating treatment with ticagrelor 60 mg after a myocardial infarction in real-world clinical practice, and describe their patient characteristics and duration of treatment. If the a priori threshold of 5,000 person-years on treatment with ticagrelor 60 mg is met, outcome events (bleeding and cardiovascular events) will also be analysed and described.
This observational cohort study will include patients initiating treatment with ticagrelor 60 mg after a myocardial infarction (MI), and describe their patient characteristics and persistence to treatment. To contextualise the characteristics of the ticagrelor patients, two reference cohorts will be created, including patients treated with another P2Y12 inhibitor than ticagrelor (clopidogrel, prasugrel, or ticlopidine), and patients not treated with any P2Y12 inhibitor, within a comparable timepoint from an MI as for the ticagrelor 60 mg patients. If the a priori threshold of 5,000 person-years on treatment with ticagrelor 60 mg is met, to ensure sufficient precision, outcome events (bleeding and cardiovascular events) will also be analysed and described. Outcome events will only be described in the ticagrelor cohorts; no comparison of outcomes will be made between the ticagrelor and the reference cohorts. The primary outcome is bleeding requiring hospitalisation. The secondary outcomes include components of the primary outcome, and cardiovascular outcomes. Persistence to treatment with ticagrelor 60 mg will also be assessed The study will be performed in the US and 4 European countries (Sweden, United Kingdom, Italy, Germany). ;
