Outcomes in UK ACS Patients Prescribed Ticagrelor

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 4, 2016

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
March 31, 2016

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
