"Myocardial Infarction"

An infarction is a death of tissue caused by lack of blood supply. A myocardial infarction is the death of heart muscle caused by blockage of flow through one or more coronary arteries.

Among the dangers of this are a loss of pump function with acute heart failure, or electrical derangement in the heart leading to fatal arrythmia.

As a young, previously healthy man, Jesus would appear to have been at little risk for heart attack.
