A heart attack, also called myocardial infarction, happens
most often when your heart muscles are damaged or
destroyed by a lack of oxygen-rich blood. Recognize the
symptoms, know the causes, and prevent a heart attack in
yourself or in a loved one. Continue to find a heart specialist near you.
What Causes A Heart Attack?
Coronary Artery Disease
The most common cause of heart attack is coronary artery
disease (CAD). Your coronary arteries supply blood to your
heart muscle. If youâ€™re diagnosed with coronary artery
disease, it means a fatty deposit (plaque) has either built up
or has broken off and formed a clot in at least one of your
coronary arteries. This plaque or clot can restrict oxygen-rich
blood flow to your heart, causing chest pain (angina) or
a heart attack. Continue to find a heart specialist near you.
