how long does it take myocardial infarction to develope or necrosis to from?
A myocardial infarction, or a heart attack, occurs when there is a loss of blood supply to the heart muscle tissue. Cardiac cell death, or necrosis, can occur within four to six minutes of the initial loss of blood supply at the area of infarction. Brain death can also occur within this time frame if CPR is not initiated, as the heart is unable to supply blood to the brain and body. Hope this was helpful.
