Extreme stress and intense emotional responses can trigger catastrophic cardiovascular events, such as stress-induced cardiomyopathy and fatal autonomic surges.
The retrieved papers provide robust medical and physiological evidence demonstrating that extreme emotional stress, fear, and sympathetic surges can cause fatal cardiovascular outcomes, such as Takotsubo cardiomyopathy and psychophysiological death (often referred to as voodoo death). Papers [1], [3], [10], and [11] explicitly detail the mechanisms by which extreme stress responses lead to life-threatening cardiac events. There are no papers refuting this claim.
