Myocardial Infarction | Drug: Beta-blockers withdrawal Drug: Continuation of the Betablockers (βB) treatment | Phase 4 |
Despite the outstanding progress made in cardiac care over the last few years, cardiovascular diseases remain the leading cause of morbidity and mortality in developed countries.
After the initial clinical event, patients are considered to have a chronic disease which combined with the increasing actual life expectancy patients with CAD are a major source of expenses due to their life-long treatment and follow-up.
ΒB are prescribed during the initial hospitalisation for MI and in the post-MI phase. European (European Society of Cardiology, ESC) and American (ACC/AHA) guidelines initially gave βB therapy a class I recommendation for MI or acute coronary syndrome (ACS) for the first year of treatment and extended such recommendation without solid data up to 3 years after MI , . However, there has been no recent clinical trial to evaluate safety and efficacy of long term ΒB therapy in the contemporary therapeutic era. Taking such lack of evidence in account and acknowledging that clinical practice has changed, the latest ESC STEMI (2014) and NSTEMI (2015) Guidelines degraded the recommendation for the use of ΒB in post MI patients (Class IIa B) during the hospitalization period and they question the validity of its use after the initial stabilization phase. This was confirmed in the 2017 STEMI Guidelines.
The primary objective of the ABYSS trial is to demonstrate the non-inferiority of the interruption of ΒB therapy after an uncomplicated MI after six months or more of follow-up compared to the continuation of βB evaluated by the primary endpoint.
The primary endpoint of the study will be evaluated, with one-year minimum follow-up, and will be the composite of Major Adverse Cardiovascular Events (MACE) measured at the longest follow-up including:
- All-cause death
- Stroke
- Myocardial infarction Hospitalisation for other cardiovascular (CV) reason.
It is expected that the interruption of βB therapy will not alter the prognosis of patients and improve safety and quality of life of patients and considerably reduce healthcare direct or indirect costs.

Experimental: Discontinuation of the Betablockers (βB)
1850 post-MI patients treated with chronic βB treatment will undergo withdrawal of their βB treatment..

- The composite of Major Adverse Cardiovascular Events (MACE) [ Time Frame: Through study completion, with a minimum of 1 year ]
Will be evaluated with one-year minimum follow-up and will be the composite of Major Adverse Cardiovascular Events (MACE) including:
- All-cause death
- Myocardial infarction (MI)
- Stroke
- Hospitalisation for any cardiovascular (CV) reason.
- Quality of life [ Time Frame: Through study completion, with a minimum of 1 year ]will be evaluated by the questionnaire EQ5D-5L Score (0 to 1) and EQ5D-5L Scale (0 to 100) with higher scores indicating a better quality of Life.
- Anxiety and Depression [ Time Frame: Through study completion, with a minimum of 1 year ]will be evaluated by using the HADS questionnaire to detect the presence of depression and anxiety ( there is no score; this will be determined by the response selected by the patient with "no" = no discomfort to "a lot" = significant discomfort
- Erection Dysfunction [ Time Frame: Through study completion, with a minimum of 1 year ]A precise evaluation of Erectile dysfunction will be proposed to male patients using an internationally validated questionnaire IIEF (International Index of Erectile Function) in French with 5 questions whose answer is graded from 0 to 5 per question
- Libido [ Time Frame: Through study completion, with a minimum of 1 year ]An evaluation of lack of sex drive will be evaluated by answering the following questions about the sexuality of the patient The frequency and degree of sex drive (self evaluation)
- Exercise Capacity [ Time Frame: Through study completion, with a minimum of 1 year ]
will be evaluated by answering the following simple questions :
- The weekly physical activity and the sport practiced
- Participation in competitions or not additionally, the recording the results of stress tests when available
- Pre- and post - inclusion stress/ Strain test data
- Side effects [ Time Frame: Through study completion, with a minimum of 1 year ]will be evaluated by answering the following questions: Presence of Blury Vision, Sensation of cold hands and feets, Insomnia and palpitations
