Physical activity can prevent a heart attack because you're increasing your blood flow through your body. You're also making you cholesterol ratio between you "good and bad" cholesterol balance out. Example, if you have a high "bad cholesterol" (LDL level) and a high "good cholesterol" (HDL level), the exercising will help increase your HDL levels and lower your LDL cholesterol.
Also, a lot of people don't realize that the younger you are and have a heart attack, the LEAST likely you will survive. This is opposite of a normal idiopathy.
The younger we are, the less "added pathways" our veins/arteries have within our heart. Exercising can actually create these additional pathways within our heart to held reduce the risk of a heart attack and if someone does have a heart attack, they have addition pathways for blood to flow and less of the heart muscle will die.
This is true. If it has nothing or little to do with genetics than it is a skill based action, practice and repetition can help improve these.
