About this study
Study of heterogeneity in associations between social deprivation and the initial presentation of 12 cardiovascular diseases.
Read the detailed description
This study is part of the CALIBER (Cardiovascular disease research using linked bespoke studies and electronic records) programme funded over 5 years from the NIHR and Wellcome Trust. The central theme of the CALIBER research is linkage of the Myocardial Ischaemia National Audit Project (MINAP) with primary care (GPRD) and other resources. The overarching aim of CALIBER is to better understand the aetiology and prognosis of specific coronary phenotypes across a range of causal domains, particularly where electronic records provide a contribution beyond traditional studies. CALIBER has received both Ethics approval (ref 09/H0810/16) and ECC approval (ref ECC 2-06(b)/2009 CALIBER dataset).

What is being measured
The primary outcome is the main question the study is designed to answer.
Hazard ratios for the associations between social deprivation and initial presentation of 12 cardiovascular diseases.
Associations studied:
- overall
- by sex
- by age group
- in high risk groups (smokers, hypertensive disease, obese, diabetic, depression)
- before and after the introduction of the Quality and Outcomes Framework in England
Measured: Followed for the duration of general practice registration between January 1997 and March 2010, an expected average of 5 years
Secondary outcomes (1)
Lifetime cumulative incidence per quintile of social deprivation
Measured: Followed for the duration of general practice registration between January 1997 and March 2010, an expected average of 5 years
