While it is easy to assume the claim that regularly drinking energy drinks leads to heart failure is true because the TikTok was created by a doctor. Jefferson Health talks about how an excess in energy drinks can cause health problems and how it is important to pay attention to how you are feeling. It also discusses the importance of the intake of caffeine. Drinking too much can cause problems, so it is important to watch your intake. So, there is not a direct link to heart failure, but it is important to listen to your body and watch how much caffeine you drink. So while the claim is not completely false, it is misleading.
