This guideline covers care and treatment of people aged 18 and over with a type of heart attack known as spontaneous onset of myocardial infarction with ST-segment elevation (STEMI). It aims to ensure that adults with STEMI are assessed and treated as soon as possible to minimise the damage to their heart. It also aims to help commissioners and healthcare professionals configure services so that people with STEMI can have the best outcomes.
ST-segment-elevation myocardial infarction (STEMI) occurs when a coronary artery becomes blocked by a blood clot, causing the heart muscle supplied by the artery to die. It belongs to a group of heart conditions known as acute coronary syndromes.
