Are treatment effects of ACEI and ARB in post-MI patients homogeneous?

he outcome of patients with acute myocardial infarction (MI) has been substantially improved by the introduction of reperfusion therapy and its continuous refinement. Current reperfusion methodology salvages more than 50% of the ischemic myocardium from infarction in approximately half of acute MI patients without cardiogenic shock. 1 However, in 25% of acute MI patients, myocardial salvage by reperfusion is minimal, leaving the infarct larger than 20% of the ventricular mass.1 It is this subgroup of patients with large infarcts that particularly needs potent therapy for preventing subsequent heart failure.
