Post-MI complications

Acute coronary syndrome can be classified as follows:

• ST-elevation myocardial infarction (STEMI): ST-segment elevation + elevated biomarkers of myocardial damage
• non ST-elevation myocardial infarction (NSTEMI): ECG changes but no ST-segment elevation + elevated biomarkers of myocardial damage
• unstable angina

1. Type 1 MI = STEMI and NSTEMI
2. Type 2 MI = mismatch between myocardial supply and demand
3. Type 3 MI = associated with sudden cardiac arrest but not documented antemortem
4. Type 4 MI = PCI related
5. Type 5 MI = CABG related

The management of ACS depends on the particular subtype. NICE management guidance groups the patients into two groups:

• 1. STEMI
• 2. NSTEM/unstable angina
