E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Patients admitted to hospital with acute myocardial infarction treated With reperfusion therapy (i.e trombolysis or percutaneous coronary intervention) |
|
E.1.1.1 | Medical condition in easily understood language |
The study aims to investigate whether oral betablocker (BB) therapy is superior to no such treatment following an acute myocardial infarction (AMI). |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Cardiovascular Diseases [C14] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to test whether oral BB therapy reduces the risk of all-cause death or non-fatal MI compared to no such therapy, in patients with AMI treated with PCI or thrombolysis and no clinical signs of heart failure and/or LVEF ≥ 40%. |
|
E.2.2 | Secondary objectives of the trial |
The key secondary objectives are:
• To study whether oral BB therapy reduces the risk of each of the components of the primary end-point separately, compared to no such therapy
• To study whether oral BB therapy reduces the risk of hospitalization for ventricular arrhythmias or heart failure compared to no such therapy
• To study whether oral BB therapy reduces the risk of cardiovascular death compared to no such therapy
• To conduct a health economic evaluation including drug use, health care utilization, employment, income, and benefit take-up
• To compare sociodemographic, clinical, and psychosocial characteristics between the two study arms
• To assess study safety
• To assess efficacy between subgroups
Post-trial objective:
• To perform a joint analysis of the data with the REDUCE study (Sweden) and DANBLOCK (Denmark). This analysis will comprise 16500 patients, giving increased power and precision to make clinical decisions on both primary and secondary endpoints. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Exploratory biobanking objectives:
• To study the proportion and predictors of non-adherence with BB, statins and other cardiovascular drugs assessed by direct methods quantifying drug concentrations in blood
• Identify pharmacokinetic, pharmacogenetic and direct drug-related markers associated with side-effects and suboptimal response to treatment with cardiovascular drugs
|
|
E.3 | Principal inclusion criteria |
• 18 years or older
• Diagnosed with an acute MI type I according to the "Universal Definition of MI" (Defined as a detection of a rise and/or fall of cardiac biomarker value, preferably troponin, with at least one value above the 99th percentile upper reference limit and with at least one of the following; a) symptoms of ischemia, b) new or presumed new significant ST-segment-T wave changes or new left bundle branch block, c) development of pathological Q waves, d) imaging evidence of new loss of viable myocardium or e) identification of an intracoronary thrombus by CAG)
• Must have been treated with PCI or thrombolysis during current hospitalization
• Signed informed consent and expected cooperation of the patient according to ICH/GCP and national/local regulations
• Have a national personal identification number and not be expected to emigrate during study |
|
E.4 | Principal exclusion criteria |
Study subjects must not meet any of the following criteria:
• Having a condition where BB-therapy is required, including but not limited to:
o Arrhythmias
o Hypertension
o Cardiomyopathies
o Clinical diagnosis of heart failure
o LVEF < 40% by echocardiography
• Contraindications to BB-therapy:
o Bradyarrhythmias
o Hypotension
o Severe peripheral artery disease
o Previously known side-effects causing withdrawal
o Severe chronic obstructive pulmonary disease
o Others, according to the responsible investigator
• Any condition (e.g. psychiatric illness, dementia) or situation, that in the investigators opinion could put the subject at significant risk, confound the study results, interfere significantly with the subject participation in the study, or rendering informed consent unfeasible
• Women of childbearing potential using inadequate birth control, pregnancy, and/or breastfeeding. Adequate contraception includes oral, injected or implanted hormonal methods of contraception, placement of an intrauterine device or system, vasectomized partner or sexual abstinence.
• Short life expectancy due to other medical conditions
Previous treatment with a BB is not an exclusion criterion for enrollment into the BETAMI study. |
