{{Main|Myocardial infarction}}

Patients arriving at the emergency department with a myocardial infarction (heart attack) are likely to be triaged to the resuscitation area. They will receive oxygen and monitoring and have an early [[Electrocardiogram|ECG]]; aspirin will be given if not [[Contraindication|contraindicated]] or not already administered by the ambulance team; morphine or diamorphine will be given for pain; sub lingual (under the tongue) or buccal (between cheek and upper gum) glyceryl trinitrate ([[Nitroglycerin (drug)|nitroglycerin]]) (GTN or NTG) will be given, unless contraindicated by the presence of other drugs.

An ECG that reveals ST segment elevation suggests complete blockage of one of the main coronary arteries. These patients require immediate reperfusion (re-opening) of the occluded vessel. This can be achieved in two ways: [[thrombolysis]] (clot-busting medication) or [[Angioplasty|percutaneous transluminal coronary angioplasty]] (PTCA). Both of these are effective in reducing significantly the mortality of myocardial infarction. Many centers are now moving to the use of PTCA as it is somewhat more effective than thrombolysis if it can be administered early. This may involve transfer to a nearby facility with facilities for [[angioplasty]].
