Energy Drinks, ER Surge?

A new review of federal safety records found that cardiac arrest showed up eleven times more often in cases tied to energy drinks and stimulant supplements than in cases without them.

Quick Take

Researchers reviewed over 28,000 adverse event reports sent to the Food and Drug Administration (FDA) from 2017 through 2025.
Reports naming caffeine or stimulant products showed cardiac arrest eleven times more often and heart attacks 4.5 times more often.
Most of the affected people were young adults between ages 18 and 34, a group not usually watched closely for heart risk.
Industry groups and outside doctors say the data cannot prove the drinks caused the events, only that a pattern exists.

What The American Heart Association Review Found

The American Heart Association says researchers combed through 28,345 safety reports filed with the FDA over eight years. Of those, 854 mentioned caffeine or stimulant-containing energy drinks or supplements, while 27,491 did not involve those products. The reports covered a wide range of problems, from fainting spells to full cardiac arrest, giving researchers a large pool to compare.

The gap between the two groups stood out. People in the stimulant-linked reports showed cardiac arrest far more often, and the pattern held even after researchers accounted for age. The findings are preliminary and were set to be presented at the American Heart Association’s Scientific Sessions 2026 conference, with young adults making up an unusually large share of the cases.

The Range Of Heart Problems Tied To These Reports

The analysis was not limited to cardiac arrest. Reports also described heart attacks, abnormal heart rhythms known as ventricular arrhythmias, heart palpitations, rapid heart rate, chest pain, and fainting episodes doctors call syncope. That breadth matters because it suggests the heart risk, if real, is not a single rare event but a cluster of related warning signs showing up together.

Researchers were careful to frame this as a pattern worth watching, not a verdict. Medical News Today reported the team itself stressed the results show an association, not proof that these products cause heart damage. That distinction separates a legitimate research finding from a conclusion ready for a courtroom or a warning label.

Why Doctors And Industry Groups Are Pushing Back

Cardiologist Gregory Marcus said the findings raise real concern about products with very high caffeine content, but stopped short of calling it proof. He noted other factors could explain the numbers, since the data cannot rule out alcohol, drugs, or undiagnosed heart conditions in the people who got sick. That is a fair and grounded caution, not a dismissal of the signal researchers found.

The Council for Responsible Nutrition, a supplement industry trade group, went further. It argued the study lumped together very different products, including ingredients like ephedra and DMAA that cannot legally be sold in supplements today, and that it never confirmed how much of anything people actually consumed. Andrea Wong of the group added that an eleven-fold difference in reports does not mean any single drinker faces eleven times the risk.

These are not fringe complaints. The FDA’s own reporting system is voluntary, meaning doctors, families, or companies choose whether to file a report at all. A 2012 FDA investigation into energy drinks ran into the same wall, with spokeswoman Shelly Burgess saying at the time that no causal link had been established and other products might have played a role. A separate sports medicine review found that co-ingested drugs, genetic conditions, and intense exercise often muddied the picture in individual cases.

None of that erases the core finding. A large, federally tracked dataset shows heart emergencies clustering around caffeine and stimulant products far more than chance would predict, and young adults are showing up in numbers that should concern any parent or coach. Common sense says a signal this size, even from imperfect data, deserves real follow-up study with verified dosing and clinical review, not a shrug from an industry eager to protect sales.
