Energy drinks linked to heart attacks in young people

A new study suggests caffeinated energy drinks and supplements are linked to heart problems in young people, including heart attacks. The findings, to be presented at the American Heart Association’s Scientific Sessions, show a disproportionate association between these products and serious cardiovascular events. Adults aged 18 to 34, who are typically not considered high-risk for cardiovascular issues, were particularly affected.

While moderate coffee consumption is generally considered safe, energy drinks often contain far higher levels of caffeine. Dr. Gregory Marcus, chairman of the American Heart Association, called for further research to understand the full impact of caffeinated drinks on young people. Reports showed heart attacks were nearly 11 times more common in connection with caffeinated drinks compared to caffeine-free products.

Caffeine increases heart rate and blood pressure, and some energy drinks contain stimulants like guarana, which add to the caffeine content. The drinks' high caffeine content, combined with factors like dehydration and lack of sleep, can exacerbate the risk of heart issues, especially in young people who may have underlying heart conditions.
