What is a inferior posterior infarct?
Posterior extension of an inferior or lateral infarct implies a much larger area of myocardial damage, with an increased risk of left ventricular dysfunction and death. Isolated posterior infarction is an indication for emergent coronary reperfusion.
What is a posterior STEMI?
A posterior wall MI occurs when posterior myocardial tissue (now termed inferobasilar), usually supplied by the posterior descending artery — a branch of the right coronary artery in 80% of individuals — acutely loses blood supply due to intracoronary thrombosis in that vessel.
What does inferior STEMI mean?
an inferior STEMI. An anterior STEMI is the front wall of the heart, and the most serious. A posterior STEMI is the back wall of the heart. An inferior STEMI is the bottom wall of the heart.
How can you tell if you have a posterior STEMI?
The ECG in posterior STEMI is first characterized by ST-depression in the anterior leads. The ST depression is often deep (>2mm) and flat (horizontal). There will be a large R-wave in V2-3, even bigger than the S-wave. Normal R-waves progressively increase in height across the precordial leads.
What is the most probable treatment for STEMI?
The priority in treating a STEMI heart attack is to open the artery quickly, saving as much heart muscle as possible. Treatment options include percutaneous coronary intervention (PCI), a term that encompasses both angioplasty and stenting; clot-busting medication; and coronary artery bypass graft surgery (CABG).
What is the goal for PCI when treating a STEMI?
The goal of PCI in these patients is to keep neurological function intact to increase survival.

How do you treat an inferior MI?
The traditional field treatment for an MI is aspirin and oxygen, with nitroglycerin and morphine for pain (often referred to as MONA). Some services now administer angiotensin converting enzyme (ACE) inhibitors, clopidogrel, and beta-blocking drugs as well.

What happens during a STEMI?
STEMI will typically result in intense pain or pressure in or around the chest, often radiating to the neck, jaw, shoulder, or arm. Profuse sweating, breathlessness, and a profound sense of impending doom are also common.
