Energy drinks and stimulant-containing supplements have been linked to the risk of serious heart problems, including cardiac arrest and heart attacks, particularly among young adults.
That’s according to new research released by the American Heart Association, which will be presented at the AHA Scientific Sessions in Chicago, November 6–9, 2026.
A retrospective observational analysis looked at more than 28,000 reports submitted to the FDA of cardiovascular events, including cardiac arrest, myocardial infarction (heart attack), ventricular arrhythmias (abnormal rhythms), palpitations, tachycardia (rapid heart rate), chest pain and syncope (fainting).
