Category 2 : An increase in myocardial oxygen demand due to tachycardia, elevated ventricular afterload (BP or aortic stenosis), or increased wall stretch (admittedly this latter is more complicated) or a decrease in oxygen supply due to hypotension, anemia, hypoxia, or a combination of all of the above. This results in Type I MI.
