What is an anterior infarct on an ECG?
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.
Is anterior infarct serious?
In the United States, between 1.2 and 1.5 million people suffer a myocardial infarction (MI) every year. And among MIs, anterior-wall MIs are the most serious and have the worst prognosis.
What is the treatment for anterior infarct?
Treatment may include taking medications to resolve blood clots, reduce pain, or slow down your heart rate. The doctor may also send you to undergo a minimally invasive procedure called percutaneous coronary intervention (PCI), formerly referred to as an angioplasty with a stent.
What is anterior myocardial ischemia?
Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). If the plaques rupture, you can have a heart attack (myocardial infarction).
What triggers anterior infarct?
Prolonged ischemia due to LAD artery occlusion leads to anterior MI. Atherosclerotic plaque rupture, followed by thrombus formation is the most common cause of anterior MI.[3] This acute reduction of blood supply to the myocardium results in necrosis of the heart muscle.
How long can you live with myocardial infarction?
About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
What would be expected when evaluating an ECG for an anterior infarction?
ST elevation in I and aVL with reciprocal ST depression in lead III. Q waves are present in the septal leads V1-2. These features indicate a hyperacute anteroseptal STEMI.
