A left ventricular myocardial infarction (LVMI) is a type of heart attack where the blood flow to a part of the left ventricle of the heart is blocked. This blockage is usually caused by a blood clot in a coronary artery. The left ventricle is the largest and strongest chamber of the heart and is responsible for pumping oxygen-rich blood to the rest of the body. When a significant portion of the left ventricle is damaged due to an infarction, it can lead to reduced cardiac output and potentially life-threatening complications. If a patient with an LVMI is hypotensive (having low blood pressure), it suggests that the infarction is a large one, and there is a high risk of developing cardiogenic shock, which is a severe condition where the heart cannot pump enough blood to meet the body's needs. In the context of an inferior wall AMI (anterior myocardial infarction), it's important to consider the possibility of a right ventricular AMI as well. The right ventricle, which pumps blood to the lungs, can also be affected by a heart attack, and this can be particularly evident in patients with an inferior wall AMI due to the anatomy of the coronary arteries.

If a patient with a left ventricular AMI is hypotensive, the infarction is a large one, and cardiogenic shock is likely to follow. Right ventricular AMI. Suspect a right ventricular AMI in all patients who present with an inferior wall AMI.
