Not all heart attacks are the same. An Anterior Wall MI, caused by a blockage in the LAD artery, tends to be the most severe since it affects a large area of the heart muscle. An Inferior Wall MI affects the lower heart wall and often brings nausea and a slow heart rate. A Right Ventricular MI usually occurs alongside an inferior MI and can cause low blood pressure. All three are medical emergencies that need immediate treatment.
Key Points
- • Anterior Wall MI (LAD blockage) is usually the most severe, affecting a large part of the heart muscle
- • Inferior Wall MI can present with nausea, vomiting, and a slowed heart rate
- • Right Ventricular MI often occurs together with an inferior MI and can cause low blood pressure
