A preliminary analysis of FDA safety reports has found that cardiac arrest and heart attack appeared more often in cases involving energy drinks or stimulant supplements. The analysis, which examined over 28,000 reports, indicated that cardiac arrest occurred at approximately 11 times the frequency in products containing caffeine and stimulants compared to those without them. Energy drinks and stimulant supplements were found to be disproportionately represented in reports of serious cardiovascular events.

Researchers involved in the analysis cautioned that the data collected cannot prove causation between the consumption of energy drinks or stimulant supplements and the occurrence of cardiac events. The findings were presented at a scientific session of the American Heart Association.

Disagreement on causation

While researchers cautioned that the data cannot prove causation, some outlets presented this nuance more prominently than others. Medical Daily stated that researchers "cautioned the data cannot prove causation." La Repubblica reported, "There was no evidence of cause-effect relationship." However, other reports, such as those from Prensa Latina, stated "Energy drinks cause heart attacks and heart attacks in young people."

What the coverage left out

None of the left, centre, or right-rated digests mention the specific number of reports analysed, which was stated as over 28,000 in some unrated outlets and specifically 28,345 in Observador.

Is Energy drinks linked to cardiac arrest in FDA reports left or right?
Neither side dominates it. Of the 67 rated outlets on this story, 22% are rated left, 54% are rated centre, 24% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Energy drinks linked to cardiac arrest in FDA reports biased?
Energy drinks linked to cardiac arrest in FDA reports is one event reported by 96 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Energy drinks linked to cardiac arrest in FDA reports?
96 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
What did the preliminary analysis of FDA reports find?
A preliminary analysis of FDA safety reports found that cardiac arrest and heart attack appeared more often when energy drinks or stimulant supplements were involved. Cases of cardiac arrest were reported at approximately 11 times the frequency in products containing caffeine and stimulants compared to those without them.
Can the study prove that energy drinks cause cardiac events?
No, researchers cautioned that the data cannot prove causation between energy drinks or stimulant supplements and the occurrence of cardiac events. The analysis identified an association but not a direct cause-and-effect relationship.
Which age group was most affected in the reports?
The reports indicated a particular association with serious cardiovascular events in young adults. Some reports specified an age range of 18 to 34 years old as being particularly noted in the analysis of adverse events.
