The purpose of this study is to estimate the risk of myocardial infarction (MI)/coronary death associated with use of monotherapy low dose ASA (single antiplatelet) as well as concomitant use of monotherapy low dose ASA and proton pump inhibitors (PPIs) in patients with serious coronary heart disease using two UK primary care databases.
Nonfatal Myocardial Infarction

Cases with nonfatal MI or coronary death
Age, sex, and calendar-year matched controls sampled from the original study cohort to be a round number of at least four times the number of cases

||50 Years to 84 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
Individuals aged 50-84 years who from 1 January 2000 to 31 December 2007 had a documented evidence of a hospitalization for a serious acute coronary event (MI, revascularization of coronary arteries or unstable angina) and who were alive 1 month after this event in two primary care clinical practice databases in the UK: General Practice Research Database (GPRD) and The Health Improvement Network (THIN).
- As above ( study population description).
- All individuals aged 50-84 years with at least one year of enrolment with the primary care physician (PCP) and a computerized prescription history of at least one year before the start of the study.
- Recorded diagnosis of cancer prior to study start.
- Patients aged ≥ 70 years with a follow-up longer than one year if having fewer than two recorded consultations with a primary care physician (PCP) during their entire follow-up (proxy for incomplete and invalid data recording
