Thus, vasopressin is theorized to be of increased benefit over epinephrine in cardiac arrest due to its properties of not increasing myocardial and cerebral oxygen demands. [18] This idea has led to the advent of several studies searching for the presence of a clinical difference in benefit of these two treatment choices.
In 2021, the American Heart Association clarified that "heart attack" is often mistakenly used to describe cardiac arrest. While a heart attack refers to death of heart muscle tissue as a result of blood supply loss, cardiac arrest is caused when the heart's electrical system malfunctions. Furthermore, the American Heart Association explains ...
Unlike cardiac arrest, a heart attack is a circulation problem. When circulation is blocked or cut off in some way and blood is no longer supplied to the heart muscle, this can damage that muscle ...
A cardiac arrest is when a person's heart stops pumping blood around their body and they stop breathing normally. Calling before a heart attack becomes cardiac arrest requires knowing the signs ...

Vasopressin comes as the second-line agent. [24] However, high-dose therapy is linked to excessive coronary, splanchnic vasoconstriction, and hypercoagulation. [6] Excessive vasoconstriction can cause cardiac output reduction or even fatal heart complication particularly in those with weak myocardial function. [6] [4] [28] [29]
With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [2]
