1. Study identification
EU PAS Register NumberEUPAS10726
Official titleObservational study of post-myocardial infarction with a long follow-up
Study title acronymEOLE
Study typeObservational study
Brief description of the studyThe EOLE study was requested by French authorities at the time of new omega-3 supplementation marketing for secondary prevention of post-myocardial infarction. The main research question is to assess the impact of recommended cardiovascular drugs (beta-blockers, acetylsalicylic acid or other antiplatelet agents, statins or other lipid lowering agent, angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, and omega-3 supplementation), and dietary lifestyle guidelines in real-life to all cause mortality in secondary prevention of myocardial infarction in France after 6 years of follow-up. Hospital and non-hospital cardiologists included 5527 patients from April 2006 to June 2009. Socio-demographic data, myocardial infarction characteristics, cardiovascular risk factors, history and associated cardiovascular diseases, last lab test results, cardiovascular drugs, cardiovascular rehabilitation program, tobacco use, drugs taken, hospitalisations since myocardial infarction and vital status were collected using a medical questionnaire completed at first post-myocardial infarction consultation, and a patient self-administered questionnaire filled out at inclusion, 6 month, 2, 3, 4, 5 and 6 years. At 6 years follow-up, the vital status of all patients will be ascertained from the national death registry using a standard approved national procedure whereby the national identification database is searched (decree #98-37 of 16 January 1998, modified procedure INSEE/INSERM), and failing that, through patient/relatives/physicians. An interim analysis will be planned after 3.5 years of follow-up

All cause mortality at 6 years follow-up
Are there secondary outcomes?Yes
Coronary & cardiovascular mortality
Coronary & cardiovascular morbi-mortality

13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Patients have a 6-year follow-up with 6 evaluation points: at 6 month, at 2, 3, 4, 5 and 6 years.
15. Data analysis plan
Please provide a brief summary of the analysis method
Statistical analysis will be carried out by the Bordeaux pharmacoepi according to a documented and approved Statistical Analysis Plan (SAP). Statistical analysis will be performed after database lock using SAS® software (SAS Institute, last version, North Carolina, USA). Blind double programming will be used for the main outcome measures. Qualitative variables (dichotomous or categorical) will be described in terms of number and frequency. Quantitative variables will be described in terms of mean, standard deviation, median, first and third quartiles, as well as deciles.
The Kaplan Meier estimate will be used to estimate the occurrence of all-cause death. The Cox proportional hazard regression model adjusted for gender, age, cardiovascular risk factors, other myocardial infarction prevention drugs and propensity score to be exposed at inclusion will be used to estimate the risk of death in patients exposed and not exposed to each secondary prevention drug.
