About this trial
This is an interventional prevention trial for Atherosclerosis focused on measuring Omega-3 fatty acids, dietary supplementation, atherosclerosis
Eligibility Criteria
Inclusion Criteria:
- Subjects must meet the current guideline criteria for atherosclerosis, like coronary, peripheral or carotid artery disease, like previous myocardial infarction or acute coronary syndrome, coronary revascularization (operation or transluminally), or positive angiography or ultrasound.
- Age: 30 - 75 years
- Low Omega-3 Index (<5%)
- Subjects must have adequate fluency in German or English to complete baseline and follow-up interviews.
- Stable intake of food containing EPA+DHA before and during study
- Subjects must be able and willing to give written informed consent, and to comply with study procedures.
Exclusion Criteria:
- Subjects for whom the intake of omega-3 fatty acids is mandatory according to recent treatment guidelines or who take omega-3 fatty acids supplements on a regular basis.
- Patients consuming >2 portions of fatty fish / week
- Patients with serious bleeding disorder. Use of platelet inhibitors or anticoagulation with a target INR of 2.0 - 3.0 is not an exclusion criterion.
- Subjects with any acute and life-threatening condition, such as collapse and shock, acute myocardial infarction (last three months), stroke, embolism.
- Subjects with significant medical co-morbidity, seriously limiting life expectancy or insulin-treated diabetes mellitis or a BMI>30
- Allergy/intolerance or history of hypersensitivity to components of study intervention, like lactose.
- Pregnant subjects - due to any possible teratogenic effects of study nutrition on the fetus - and breastfeeding subjects. In addition, women of childbearing potential who will not practice a medically accepted method of contraception will be excluded.
- Subjects who, in the investigator's judgement, will not likely be able to comply with the study protocol or with known drug- or alcohol abuse/dependence in the past 2 years.
- Use of any investigational agents within 30 days prior to t0

Arm Type
Active Comparator
Placebo Comparator
Arm Label
Convenience drink with EPA and DHA
Convenience drink without EPA and DHA
Arm Description
Daily consumption of 200 ml convenience drink, containing 0.5 g EPA and DHA (Omega-3 Fatty Acids)
Daily consumption of 200 ml convenience drink, not containing 0.5 g EPA and DHA (Omega-3 Fatty Acids), but containing 1.0 g of Omega-6 Fatty Acids (e.g. corn oil)
Outcomes
Primary Outcome Measures
Omega-3 Index
Percentage of eicosapentaenoic and docosahexaenoic acids in total red cell fatty acids, as determined with a standardized analytical procedure, i.e. the HS-Omega-3 Index. Currently, the target range for the HS-Omega-3 Index has been suggested to be between 8% and 11%. Cardiovascular risk increases at levels below 8%, whereas levels above 11% do not seem to confer further benefit. Values of the HS-Omega-3 Index have been found between 1.5% and 20%.
Secondary Outcome Measures
Palatability
Palatability assessed as number on a visual analogue scale from 0 - 10, with 0 being the worst and 10 being the best possible outcome

5. Study Description
Brief Summary
An increase in intake of omega-3 fatty acids should increase the Omega-3 Index. Current evidence indicates that this may lead to a reduction in risk for sudden cardiac death and atherosclerotic diseases like myocardial infarction. The aim of the study is to investigate, how supplementing a convenience drink with omega-3 fatty acids influences the Omega-3 Index, as compared to an unsupplemented matching convenience drink. Palatability and safety of the drink are also to be assessed.
