The Effect of Energy Drink on Cardiovascular Variables: A Randomized Controlled Trial

Completed · Not applicable · Has a placebo group

Conditions studied: Cardiovascular Diseases

In brief

Many adults in the United States regularly consumer energy drinks. Currently, the safety of energy drinks is still questionable and there are many reports associating energy drinks with adverse events including hospitalizations and deaths. Previous research shows that energy drink can affect heart rhythm and elevate blood pressure. However, these studies use a higher volume (32 ounces) of energy drinks than those available in the market (24 ounces). The purpose of this study is to study if 24-ounce energy drinks can significantly affect heart rhythm and elevate blood pressure when compared to a placebo.
