The critical distinction lies in the cause; while a standard heart attack is typically the result of a physical obstruction, this condition is triggered by a powerful emotional or physical stressor that temporarily stuns the heart.

Medical professionals believe this is often caused by a surge of stress hormones, such as adrenaline, which causes a brief spasm of the coronary arteries or direct toxic effects on the heart cells. The heart muscle is stunned rather than dead, and over the course of days to weeks, the left ventricle typically regains its normal shape and pumping ability.
This absence of plaque rupture is the definitive factor that separates the two conditions. However, the medical reality is more complex, and tucked into this complexity is a condition that often mimics a heart attack without involving a single clogged vessel.
