Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Polypill - 2 versions containing: Version 1c - atenolol 50mg, aspirin 75mg, simvastatin 40mg, lisinopril 10mg Details: one tablet taken orally per day for an average of 12 months. Version 2c - hydrochlorothiazide 12.5mg, aspirin 75mg, simvastatin 40mg, lisinopril 10mg Details: one tablet taken orally per day for an average of 12 months. Eligible patients will be randomised to treatment with the polypill or to continue usual care. Subjects randomised to the polypill will only take one version of the polypill. This will be determined by the participant's General Practitioner (GP).

Eligibility
Key inclusion criteria

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once subjects have been identified as high risk individuals the General Practitioner (GP) will arrange for clinical measures to assess cardiovascular disease (CVD) risk in order to confirm eligibility. If eligible, subjects will be allocated treatment using a central, computer based randomisation service.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding
