Energy Drinks Do Alter Heart Function

A study looking at the effect on heart contractility from energy drink consumption was released today via the annual meeting of the Radiological Society of North America (RSNA). Teenagers and young adults have been warned about the risks of consuming drinks high in caffeine and taurine content related to the increased number of ER visits resulting from rapid rises in blood pressure, seizures and even death. Investigators from the University of Bonn, Germany have been studying the effect of the content of these drinks on 18 volunteers aged around 27 years. MRI reports done 1 hour post consumption of drinks high in caffeine and taurine content revealed significant strain on the heart’s ability to contract from the left ventricle.  It is well known that impairment of the heart’s ability to contract appropriately could lead to arrhythmias and even seizures. More studies are needed to determine the long-term impact that energy drinks have on the heart but these short-term findings are nothing short of concerning. Do you counsel your patients to watch their caffeine intake and to avoid unnecessary consumption of energy drinks? Do you think we need tighter regulations on energy drinks?

Coffee consumption inversely linked to aggressive forms of prostate cancer. How do you often counsel patients regarding use of caffeine?

Although evidence suggests that higher coffee consumption has been associated with a reduced risk of aggressive prostate cancer, evidence of the link between coffee and the risk of overall prostate cancer has been inconclusive.  The results of this newly published prospective cohort study support the inverse link between higher coffee consumption and risk of aggressive prostate cancer, but not overall risk.  How often do you counsel patients regarding use of caffeine?
