Consumption of energy drinks might impact cardiac health by increasing blood pressure and disturbing heart rhythm, researchers have claimed.
They analysed data from seven previously published observational and interventional studies to determine how consuming energy drinks might impact heart health.
In the first part of the pooled analysis, they examined the QT interval describes a segment of the heart's rhythm on an electrocardiogram; when prolonged, it can cause serious irregular heartbeats or sudden cardiac death - of 93 people who had just consumed one to three cans of energy drinks.
They found that the QT interval was 10 milliseconds longer for those who had consumed the energy drinks.
Doctors are generally concerned if patients experience an additional 30 milliseconds in their QT interval from baseline, Sachin A Shah, PharmD, lead researcher and assistant professor at University of Pacific in Stockton, California said.
