Energy drinks, which often contain caffeine as a primary ingredient, have been associated with various cardiovascular effects, including arrhythmias. However, the evidence is not entirely conclusive and varies according to the context and population studied.
Caffeine and arrhythmias
- Caffeine and arrhythmias: The notion that caffeine increases the risk of cardiac arrhythmias is common, but evidence supporting this is not well substantiated . A prospective cohort study found that greater amounts of habitual coffee consumption were associated with a lower risk of arrhythmia, with no evidence that genetically mediated caffeine metabolism affected that association
- Caffeine and heart rate variability: In patients with long-standing type 1 diabetes, modest amounts of caffeine improved autonomic function, as assessed by heart rate variability (HRV). For individuals with abnormal HRV, regular caffeine use may have the potential to reduce the risk of cardiovascular events
Energy drinks and cardiovascular effects
- Energy drinks and cardiovascular effects: Energy drinks have no therapeutic benefit, and many ingredients are understudied and not regulated. The known and unknown pharmacology of agents included in such drinks, combined with reports of toxicity, raises concern for potentially serious adverse effects in association with energy drink use
In conclusion, while energy drinks, which often contain caffeine, have been associated with various cardiovascular effects, including arrhythmias, the evidence is not entirely conclusive. The effects of caffeine on arrhythmias may depend on the specific context and population studied. Further research is needed to fully understand the potential risks associated with energy drink consumption.
