Treatment of myocardial infarction has changed a lot over the last ten years. The treatment depends on the results of the electrocardiogram ECG. The results of blood tests such as Troponin may also be taken into account. For patients with ECG changes showing ST segment elevation the preferred option is now Primary Coronary Intervention (PCI) - Angioplasty usually with insertion of at least one stent . The rationale is to restore coronary blood flow and to keep the reopened coronary artery open.
For patients who do not have ST elevation on the ECG Non ST elevation myocardial infarction often abbreviated to NONSTEMI patients are often initially stabilised with injections of low molecular weight heparin and antipalatelet drugs such as aspirin and clopidogrel. Drugs such as beta blockers and nitrates are often used during this time. Patients with this form of myocardial infarction often undergo coronary angiography and where suitable coronary angioplasty and stenting within 48 – 72 hours.
Until recently the main treatment of acute myocardial infaction was the administration of clot busting drugs such as streptokinase through a vein. Increasingly patients with ST elevation acute myocardial infarction are being taken immediately to a specialist hospital for immediate angioplasty (Primary Angioplasty). Those with no ST elevation acute myocardial infarction often have angiography and angioplasty after about 48 hours of medical treatment.
