Does increased adrenaline rush cause some effects on the heart?

Hello sir. Can I ask you sir how exactly do you know that these are adrenaline rushes. Are you saying it based in what you think might be adrenaline rushes.The human body has a very intricate way of dealing with stress conditions. it's not only adrenaline that gets released but also cortisol. cortisol is the actual stress hormone not adrenaline. if you could describe me the conditions in which you think you are having adrenaline rush then I will be able to explain better to you as to what is happening in that conditions biochemically inside the human body.

adrenaline is released as and when required and is also degraded when not necessary. so even if we consider for once that actually adaline is getting released multiple times in someone's body it will not be continuously present and they get degraded not required and therefore will not have any permanent effects on the heart. let me know if I can help you out with any queries
