The new case report was published online Feb. 'If you are looking to have a lot of energy, get some sleep and eat a whole-food, plant-based diet,' he said.įor example, beets have been associated with improving the efficiency of cells' mitochondria, which produce the energy that people's bodies run on, Ostfeld said. There are other ways for people to feel more energized. Nonetheless, Ostfeld said, 'it is hard to argue that are healthy.' The FDA is currently investigating some reports of adverse events associated with energy drinks, according to the agency. Further studies are needed to confirm the link. It's possible that 'energy drinks might transiently negatively impact blood vessel function, and make the blood more likely to clot,' he said.īut even those several reports do not prove cause and effect, he said. Ostfeld said he has heard of other reports of heart attacks being linked to energy drinks, and there have also been some reports linking energy drinks to temporary heart palpitations. 'It is certainly possible that was related to the energy drink intake, but we could never know that for sure from a single case.' 'Since it is just one case, it is always very hard to know exactly what the cause is,' Ostfeld told Live Science. This patient's experience does not prove there is a cause-and-effect relationship between energy drink overuse and heart attack risk, Ostfeld said. Robert Ostfeld, a cardiologist and director of the Cardiac Wellness Program at Montefiore Medical Center in New York, who was not involved in the man's case. However, any report of a single case should be interpreted with caution, said Dr. The man had no other apparent risk factors for heart attack beyond consuming a lot of energy drinks and smoking, the authors wrote. However, it is also possible that the man's smoking led to the constriction of the coronary artery, the authors speculated. The excessive levels of caffeine and other potentially harmful substances in energy drinks may have reduced the blood flow in the man's coronary blood vessel to such an extent that a blood clot was able to form, causing the heart attack, according to the case report. He said he would quit smoking and drinking energy drinks. The patient went home from the hospital two days later. Doctors treated the man for his heart attack, and he recovered.
