In the universal classification of myocardial infarctions,
what class is this?
A. Type I
B. Type II
C. Type III
D. Type IV
Type I: Spontaneous
myocardial infarction due to plaque rupture, fissuring, or dissection with
thrombus formation, leading to occlusion of a coronary artery.
Type II: Type II MI refers
to myocardial infarction due to a mismatch between oxygen supply and demand,
which can occur in the setting of conditions such as coronary artery spasm,
arrhythmias, or severe hypertension.
Type III: Sudden death with
symptoms suggestive of a myocardial infarction (chest pain, ECG changes, etc.),
but without biomarkers available (for example, in a setting where the person
dies before blood can be drawn for biomarkers).
Type IV: Myocardial
infarction associated with percutaneous coronary intervention (PCI), often due
to procedural complications.

4a. PCI associated
