An inferior myocardial infarction (MI) is a heart attack or cessation of blood flow to the heart muscle that involves the inferior side of the heart. Inferior MI results from the total occlusion of either the right coronary artery in 85% of the cases or the left circumflex in 15% of the cases.
ICD-10 code I21 for Acute myocardial infarction is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
First, in order to have a subsequent MI, there must first be an acute MI that has occurred in the preceding 28 days (not 30 days). Second, codes from category I22 should ONLY be applied if both the initial and subsequent MIs are type 1 MIs (coronary involvement, NSTEMI/STEMI) or unspecified.
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
Posterior wall myocardial infarction occurs when circulation becomes disrupted to the posterior heart. It commonly cooccurs with inferior or inferolateral MI, but when in isolation, posterior myocardial infarction represents a diagnostic challenge.

ICD-10-CM Code for Old myocardial infarction I25. 2.
To report AMI, refer to the following code categories: o Subsequent Myocardial Infarction: Acute myocardial infarction occurring within four weeks (28 days) of a previous acute myocardial infarction, regardless of site. o Old Myocardial Infarction: Reported for any myocardial infarction described as older than four ...
Myocardial infarction: A heart attack. Abbreviated MI. The term "myocardial infarction" focuses on the myocardium (the heart muscle) and the changes that occur in it due to the sudden deprivation of circulating blood. The main change is necrosis (death) of myocardial tissue.

The mortality rate of an inferior wall MI is less than 10 percent. However, several complicating factors can lead to increased mortality, including right ventricular infarction, hypotension, bradycardia, heart block, and cardiogenic shock.
Thrombolytic therapy should be more successful in reducing infarct size and decreasing mortality in high risk patients with an inferior MI. Thrombolytic therapy may not decrease hospital mortality in low risk patients (baseline risk 2% to 4%) or those with symptom duration >6 h.
If the finding on an ECG is “septal infarct, age undetermined,” it means that the patient possibly had a heart attack at an undetermined time in the past. A second test is typically taken to confirm the finding, because the results may instead be due to incorrect placement of electrodes on the chest during the exam.
While inferior wall MIs traditionally have a good prognosis, there are a few factors that may increase mortality. Approximately 40% of inferior wall infarctions also involve the right ventricle. Right ventricular infarctions are very pre-load dependent, and nitrates may precipitate a drop in blood pressure.
