what is a anterior infarction?

A: Anterior infarction and its importance will help you as i have tried to summarize it from an article: The importance and urgency of reperfusion increase with the amount of myocardium at risk. Electrocardiography is an extremely useful tool for determining the location and size of an acute myocardial infarct, and every patient in the emergency room or coronary care unit deserves a physician who knows how to use electrocardiography to obtain that information1. In acute anterior-wall myocardial infarction, the amount of myocardium at risk corresponds to the number of precordial leads showing QRS and ST-segment changes and to the magnitude and extent of ST-segment...


what is a inferior infarction?

A: An inferior infarction refers to a heart attack (myocardial infarction - MI) involving the inferior and possibly the posterior wall of the heart. This area of the heart is supplied blood by the right coronary artery and sometimes a part of it is supplied by a small branch of the left coronary artery. If the right coronary artery becomes diseases with lipid laden plaques, and a plaque ruptures, it can cause an infarction in the inferior or posterior walls of the heart. This will frequently cause chest pain, nausea, vomiting, sweating, shortness of breath, and possibly syncope. Sometimes, the only symptoms are nausea and vomiting, especially...


what is an ischemic infarction?

A: ischemia is a condition in which there is not enough blood being supplied to a part of the body, such as a tissue or an organ. An infarct is an area of tissue which has died off, typically as the result of an insufficient blood supply. So, an ischemic infarction is a region of dead tissue caused by a lack of blood reaching that area. ischemic infarction often occurs in the brain, where it is commonly referred to as a stroke. It can also occur in the heart, where it is known as a


what is a Coronary Artery Aneurysm?

A: A coronary artery aneurysm is a structural abnormality of the coronary arteries. With this deformity, the wall of the artery pouches out, causing the affected artery to have an increased diameter. Symptoms of the condition could include chest pain, and complications could include heart attack. The condition can develop due to genetic abnormalities, acquired conditions, or from manipulation of the blood vessel walls. Those with this condition may be treated with medications or surgery.. Symptoms of a coronary artery aneurysm can vary. Some patients might not have any symptoms, and might only learn that they have this condition when they undergo testing for other purposes. Other patients could...


what is a Heart Attack?

A: A heart attack is the death of heart muscle caused by blockage of a coronary artery. Medically referred to as a myocardial infarction, a heart attack occurs when a coronary artery is blocked, depriving the heart of blood and oxygen. This deprivation to the heart causes chest pain and pressure, injury to the heart, and possibly death.. Though a heart attack occurs suddenly, the cause can be sudden or gradual. The leading cause of heart attack is artherosclerosis, or hardening of the arteries, due to the build up of plaque caused by cholesterol deposits. If artherosclerosis occurs in the coronary arteries, the gradual...


what is a Coronary Artery Dissection?

A: A coronary artery dissection is a separation in the layers in the wall of the coronary artery, causing a restriction in bloodflow to the heart. This can cause a myocardial infarction, where limited blood supply reduces oxygenation and begins to starve the heart muscle. The condition can be rapidly fatal if it is not caught in time. Treatment can depend on the extent of the injury to the coronary artery, and may involve medications and surgery.. This condition involves a small tear in the inner layer of the coronary artery, allowing blood to flow in and create a swelling known as a hematoma. As it builds and spreads, it tears the layers apart...


what is a Widow Maker?

A: The term "widow maker" refers to a specific type of heart attack that is known to have grave consequences. It is called this because those who suffer this type of heart attack often die, and the wives of affected men therefore often become widows. The condition is caused by a blockage in a blood vessel called the left anterior descending (LAD) artery, which normally supplies the muscle of the heart. Although patients who develop this condition can be treated, some develop heart failure or fatal heart arrhythmias despite these therapies.. In order for the heart to function properly, it needs to be supplied with sufficient amounts of fresh...

When a myocardial infarction occurs, what is it characterized by?

A: myocardial Infarction is a heart attack. If you are a woman you may not have the typical symptoms. Mine were fatigue and constantly eating sweets! Jeez, it would take hours to really answer that. Here are some answers to your direct questions. Yes an MI will cause necrosis to the affected part of the heart. The longer treatment is delayed, the further the necrosis will spread. Irritation of the pericardium will cause severe discomfort, but won''t neccessarily result in an MI. Fluid build up between the pericardium and the heart is called pericardial tamponade. That will gradually decrease the...
