A heart attack occurs when an artery supplying your heart with blood and oxygen becomes blocked.
If a plaque ruptures, a blood clot can form and block your arteries, causing a heart attack. During a heart attack, the tissue in your heart muscle dies due to lack of blood flow through your heart’s arteries.
IF SYMPTOMS WORSEN OR CHANGE UNEXPECTEDLY, TALK TO YOUR HEALTH PROFESSIONAL. CALL 000 IN AN EMERGENCY.
