Traditionally, inferior MIs have a better prognosis than those in other regions, such as the anterior wall of the heart. The mortality rate of an inferior wall MI is less than 10%. However, several complicating factors that increase mortality, including right ventricular infarction, hypotension, bradycardia heart block, and cardiogenic shock.[1][2][3]
The most frequently reported suspected drugs were the antimigraine drug sumatriptan (33 reports, 4 concerning myocardial infarction), the calcium antagonist nifedipin (9 reports, 2 of myocardial infarction) and nicotine [9 reports (8 patches, 1 chewing gum), 5 concerning myocardial infarction]. There were 18 reports of a fatal outcome.
Acute myocardial infarction, unspecified
An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
According to our angiography database, despite anterior wall MI is associated with more severity of coronary artery disease; inferior wall MI is more extent with regard to the number of involved coronary vessels. Location of MI can predict the severity and extension of infarction.
There are mainly two types of MI such as: ST Elevation Myocardial Infarction (STEMI): This is also known as Transmural Acute MI and occurs as a result of atherosclerosis involving a major coronary artery. It is classified into anterior, posterior, inferior, lateral, and septal.
Acute anterior wall ST-elevation myocardial infarction (STEMI) classically presents with ST-segment elevations in one or more precordial leads. Usually, ST-elevation in lead V1 signifies infarction of the interventricular septum. ST-elevation in leads V2–V4 indicates infarction of the anterior (or anteroapical) wall.
The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages. The right side of the heart is deflected anteriorly, and the left side is deflected posteriorly.
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.
1 for ST elevation (STEMI) myocardial infarction of inferior wall is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
I21. 1 - ST elevation (STEMI) myocardial infarction of inferior wall | ICD-10-CM.
An acute ST-elevation myocardial infarction occurs due to occlusion of one or more coronary arteries, causing transmural myocardial ischemia which in turn results in myocardial injury or necrosis.
0 for ST elevation (STEMI) myocardial infarction of anterior wall is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
The term “anteroseptal” refers to a location of the heart in front of the septum — the wall of tissue that separates the left and right sides of the heart.
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.

Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and get better with rest. Shortness of breath may also occur and sometimes no symptoms are present. The first sign is occasionally a heart attack. Other complications include heart failure or an irregular heartbeat. Specialty:
