Broken heart syndrome is a real condition, identified in Japan in the 90s, which mimics the symptoms of cardiomyopathy and can be triggered by intense emotional shock.

Takotsubo syndrome, often called 'broken heart syndrome,' has been well recognized by the scientific community since its first description in Japan in 1990. Meta-analyses and clinical studies (such as those published in the Journal of the American College of Cardiology) confirm that acute emotional or physical stress can cause a sudden weakening of the heart muscle, mimicking a heart attack. It is established that this phenomenon is real and not metaphorical, although the exact mechanism involving a sudden surge of stress hormones remains under study. The claim that one can 'die of a broken heart' is technically plausible in the most severe cases, although the majority of patients recover their cardiac function within a few weeks. The creator presents a documented medical fact here without resorting to sensationalism, by relying on an established cardiological pathology.
