What is extensive anterior myocardial infarction?

What is extensive anterior myocardial infarction?

When an anterior myocardial infarction extends to the septal and lateral regions as well, the culprit lesion is usually more proximal in the left anterior descending coronary artery (LAD) or even in the left main coronary artery. This large myocardial infarction is termed an “extensive anterior.”

Is anterior wall MI serious?

And among MIs, anterior-wall MIs are the most serious and have the worst prognosis. Typically, they are larger than other MIs, and they can result in significant ventricular wall-motion abnormalities and a significantly lower ejection fraction.

What is the treatment for anterior infarct?

The treatment of MI includes, aspirin tablets, and to dissolve arterial blockage injection of thrombolytic or clot dissolving drugs such as tissue plasminogen activator, streptokinase or urokinase in blood within 3 h of the onset of a heart attack.

What is anterior wall of heart?

Left anterior descending artery, which supplies blood to the front (anterior wall) and part of the side (anterolateral wall) of the left ventricle, to the top of the left ventricle, and to most of the wall between the ventricles (interventricular septum).

What causes anterior wall MI?

An anterior wall myocardial infarction occurs when anterior myocardial tissue usually supplied by the left anterior descending coronary artery suffers injury due to lack of blood supply.

How serious is an anterior infarct?

Anterior myocardial infarction (AMI) is a common heart disease associated with significant mortality and morbidity. Advancement in diagnosis and treatment options have led to a favorable outcome.

What are the most common complications seen with an anterior wall MI?

Complications

  • Cardiogenic shock: Cardiogenic shock complicating anterior MI is associated with higher hospital mortality when compared to inferior MI.[21]
  • Left ventricular dysfunction.
  • Left ventricular mural thrombus.
  • Ventricular septal rupture.
  • Free wall rupture.
  • Pericardial effusion from free wall rupture.

Is anterior ischemia serious?

Myocardial ischemia can lead to serious complications, including: Heart attack. If a coronary artery becomes completely blocked, the lack of blood and oxygen can lead to a heart attack that destroys part of the heart muscle. The damage can be serious and sometimes fatal.

Is anterior infarct serious?

Which coronary artery is blocked in anterior MI?

Anterior STEMI usually results from occlusion of the left anterior descending artery (LAD). Anterior myocardial infarction carries the poorest prognosis of all infarct locations, due to the larger area of myocardium infarct size.
