The Claim
Daily supplementation with 1 gram of marine omega-3 fatty acids (460 mg EPA and 380 mg DHA) for a median of 5.3 years is associated with a 28% lower risk of total myocardial infarction in healthy adults aged 50 and older, with a hazard ratio of 0.72 (95% CI: 0.59–0.90; p=0.003), although this finding was a secondary, non-pre-specified outcome and requires replication.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a daily omega-3 supplement for about five years might lower the chance of having a heart attack in people over 50 who are otherwise healthy, but scientists aren't totally sure yet and need to check this again.

What the research says
1 studyStudy: Marine Omega-3 Fatty Acids and Prevention of Vascular Disease and Cancer
This big study found that taking omega-3 fish oil pills daily for over five years didn't prevent most heart problems, but it did cut the risk of heart attacks by nearly a third in older adults. So yes, it supports the claim about heart attacks.
