So these are what isoenzymes are. So isozymes or isoenzymes are these multiple different forms of the same type of enzyme that catalyzes the same type of biochemical reaction that takes place at different locations and ore at different times. Now let's see how we can apply this to our body, to the field of medicine. So remember, that a heart attack, also known as a myocardial infraction is basically the condition by which we have a partial blockage of the blood flow to the heart of our body. For instance, previously we discussed that if we block if we create some type of embolism inside the coronary artery of our heart, that will lead to a heart attack. Now, if there's a partial blockage of blood flow to the heart, that will cause damage inside the cardiac muscle of the heart.
