Heart Attack

A heart attack occurs when part of the heart muscle is damaged or dies because of a lack of blood flow and oxygen to the area. Atherosclerosis, the leading cause of heart attacks, occurs when plaque builds up along the artery walls. Over time, the plaque hardens and may block the arteries.

If you experience symptoms of a heart attack, call 911.

Heart Attack Care at SIU Medicine

If you are experiencing symptoms of a heart attack, call 911 immediately. Do not attempt to drive yourself to the hospital. Paramedics can begin lifesaving measures sooner and alert the emergency department of your arrival.

Once a heart attack diagnosis has been made, cardiologists at SIU Medicine may provide:

• Angioplasty, which is a minimally invasive procedure used to restore blood flow to the heart. Usually a stent will be place inside the artery to prevent it from closing.
• Medications that prevent or dissolve blood clots. When given shortly after symptoms begin, clot-busting drugs can stop heart attacks as they occur, limit damage and save lives.
