Abstract:
With the use of specific cardiac markers with higher sensitivity,
new perspectives have emerged on the nature of myocardial
necrosis and injury, which are associated with acute coronary
syndrome (ACS). The third universal definition of myocardial
infarction1 now classifies myocardial infarction (MI), based
on the relevant pathology, clinical presentation, prognosis and
treatment strategy, as spontaneous MI (type 1), MI secondary
to an ischaemic imbalance (type 2), cardiac death due to sudden
fatal MI (type 3), and MI associated with revascularisation
procedures (types 4 and 5). What has also become evident is the
extent of necrosis and injury that is associated with pathologies
of other organs and conditions.
