Onset of myocardial ischemia is the initial step in the development of MI and results from an imbalance between oxygen supply and demand. Myocardial Infarction Secondary to an Ischemic Imbalance (MI Type 2) In instances of myocardial injury with necrosis, where a condition other than CAD contributes to an imbalance between

onists, which reduce myocardial ischemia by improving the myocardial oxygen supply-demand ratio, also act on the un- derlying pathophysiology of ischemia to affect cardiovascular structure and function (Table I).32 The myocardial protective effects of ACE inhibitors in pa- tients with left ventricular dysfunction or heart failure result

Demand Ischemia v. Type 2 NSTEMI Note: both are due to O 2 supply-demand mismatch between a patient’s myocardium and the coronary arteries which it supplies. However, Demand Ischemia is a term that codes to a comorbid condition (CC) while the terminology of Type 2 NSTEMI codes to major comorbid condition (MCC).

In summary, ACS is a provisional description for conditions along a continuum of myocardial ischemia and infarction. A
Distinguishing myocardial infarction type 1 and type 2.
Distinguishing myocardial infarction type 1 and type 2 from myocardial injury: Was the injury due to ischemia or another process? What was the underlying pathophysiologic mechanism leading to the MI: plaque rupture or a change in MVO2 demand or supply or a non-ischemic injury?

• Ischemia occurs when the blood supply to a tissue is inadequate to meet the tissue’s metabolic demands • Ischemia has 3 principal biochemical components: – Hypoxia (including anoxia) – Insufficiency of metabolic substrates – Accumulation of metabolic waste • Therefore, ischemia is a greater insult to the cells and

Myocardial oxygen demand is not met by oxygen supply. Coronary artery plaque may or may not be present but is unchanged. Demand Ischemia Cardiac demand ischemia is the same thing as angina, supply-demand mismatch without infarction: • Angina + elevated troponin = AMI • Demand ischemia + elevated troponin = type 2 AMI
