A healthy 26-year-old man in Texas who suffered a heart attack might be able to blame his condition on his daily habit of drinking energy drinks, according to a new report of the case.

The man told the health care workers who treated him that on the day of his heart attack he had downed eight to 10 energy drinks — and that he did that on most days, according to the case report. "With substantially higher caffeine content than soft drinks or coffee drinks, as well as other poorly studied substances, there is significant potential for harm, especially when consumed in large quantities."

The man arrived at a hospital nine hours after he began having chest pain. His left arm felt numb, he was sweating profusely and he reported vomiting prior to his arrival at the hospital.

In addition to his daily energy-drink habit, he also said he had smoked a pack of cigarettes a day for the past two years. 

Doctors treated the man for his heart attack, and he recovered. The patient went home from the hospital two days later. He said he would quit smoking and drinking energy drinks.

"Since it is just one case, it is always very hard to know exactly what the cause is," Ostfeld told Live Science. "It is certainly possible that the heart attack was related to the energy drink intake, but we could never know that for sure from a single case."

There are other ways for people to feel more energized. "If you are looking to have a lot of energy, get some sleep and eat a whole-food, plant-based diet," he said.
