Inferior wall myocardial infraction occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium .
In most patients ,the inferior myocardium is supplied by the right coronary artery . in about 6-10 % of the population ,because of left dominance ,the left circumflex will supply the posterior descending coronary artery .
Approximately 40% of all MIs involve the inferior wall .
inferior wall myocardium infractions are due to ischemia and infraction to the inferior region of the heart .in 80% of patients ,the inferior wall of the heart is supplied by the right coronary artery via the posterior descending artery .
