May 20, 2019 updated by: AstraZeneca

Health Outcomes of Patients With Acute Coronary Syndromes Prescribed Ticagrelor in UK Primary Care: a Retrospective Cohort Study

Cohort study using data from Clinical Practice Research Datalink (CPRD). The study cohort includes all patients who received at least one prescription for ticagrelor for the first time between December 2010 and March 2015, following ACS. Patient baseline characteristics will be described: (Age, Gender, Body Mass Index, Smoking status, Sociodemographic status), type of ACS and interventions, CV history and comorbidities, bleeding and respiratory history.

The following outcomes will be examined: Incidence of vascular events (composite MI, Stroke, vascular death, specific vascular event and all cause death), incidence of bleeding and incidence of dysponea. Time to event for vascular events, bleeding and dyspnoea.
