THE ESSENTIAL
- Omega-3s do not reduce major adverse cardiovascular events in patients at high cardiovascular risk.
- Consuming Omega-3s when suffering from severe heart problems also increases gastrointestinal upset.
Consuming Omega-3s is beneficial for many health conditions, but not for people with severe heart problems, according to a new study published in JAMA.
Omega-3s are found in particular in fish, nuts and rapeseed oil.
The purpose of the authors of the research was to evaluate “the effect of a high dose of omega-3 fatty acids compared to corn oil on major adverse cardiovascular events in patients at high cardiovascular risk”, in addition to the usual DMARDs such as statins.
“No significant differences”
13,078 patients were included in a randomized clinical trial. 675 hospitals from North America, Europe, South America, Asia, Australia, New Zealand and South Africa participated in the study. Balance sheet: “Daily supplementation of omega-3 fatty acids compared to corn oil did not lead to significant differences in the composite outcome of major adverse cardiovascular events,” the scientists write.
We are talking about cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, coronary revascularization or unstable angina that requires hospitalization. Therefore they conclude that “These results do not support the use of this omega-3 fatty acid formulation to reduce major adverse cardiovascular events in patients at high cardiovascular risk.”
Gastrointestinal disorders
Consuming Omega-3s when suffering from severe heart problems also increases gastrointestinal upset. “A higher rate of gastrointestinal adverse reactions was observed in the omega-3 group (24.7%) compared to corn oil-treated patients (14.7%)”, you can read in JAMA.
