    A stent will not prevent a heart attack. It's never been shown that inserting a stent actually increases a person's lifespan or reduces the risk of having a heart attack by itself. A stent will restore blood flow to a part of the heart that is being starved of blood, but it will not actually prevent a heart attack.
    The main strategies to prevent heart attacks are reduce cholesterol, reduce blood pressure, control diabetes, and stop smoking.

    In the longer term, lifestyle and risk factor modification are more important strategies.
