What is Inferior Infarct?
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 in women, the elderly, and those with Diabetes mellitus. When your physician performs an EKG, there can be changes seen in the inferior leads (II, III, aVF, and possibly V1 or V2). This is how s/he diagnoses an acute MI. You may need clotbusting medication, but if it is available, a cardiac catheterization can sometimes open the artery and prevent further damage to the cardiac muscle.

Why cardiac cells do not divide?
Cardiac tissue is a very special type of muscle tissue in that it acts like muscle AND like nerve, in order to allow for the wave of contraction to spread from one part of the heart to the other after the SA node (pacemaker) signal is received, allowing for the proper pumping action throughout the heart chambers. If cardiac muscle were allowed to divide, then branched structures of cardiac muscle could form, which could interfere with this carefully regulated contraction wave, and it could result in fibrillations. This very situation happens quite often after a myocardial infarction (blockage to the coronary arteries leading to heart attack) results in some damage to cardiac muscle, and then medical intervention allows for the person to be resuscitated. While the some of the cardiac muscle dies due to lack of oxygen supply to the cells, when oxygenated blood supply is returned, and pulse is restored, some of the cells that were inactive for a while can begin beating out of rhythm with the rest of the heart, resulting in a contraction wave that works against the overall contraction wave of the heart, leading to fibrillations (irregular contraction waves moving across the heart, not in sync with one another)...which results in no proper flow of blood into and out of the heart...requiring defibrillation to stop all cardiac contraction, allowing the brain to restart the heart and restore proper cardiac rhythm.
Which tissue has intercalated discs?
cardiac muscles/involuntary muscle
Where are intercalated disc found?
Cardiac muscle.
What is the medical term meaning death of heart muscle tissue?
It is can be called necrocardiomyopathy, cardiac myonecrosis , myocardial infarction, or simply a heart attack.
Is myocardial infarction a contraindication for surgical intervention?
It depends on what type of sugery and anesthesia you are having. It also depends on how extensive your myocardial infarction was. Your surgeon may order different cardiac tests before surgery to determine if it is safe.
What is cardiac distress?
Cardiac distress is the same thing as a myocardial infarction, or heart attack.
What is myocardial infarction risk?
Myocardial infarction risk is the risk of a heart attack. There are various algorithms that take various cardiac risk factors into account to determine MI risk. These risk factors include gender, cholesterol, smoking status, and BMI.
What is cardiac infarction?
Cardiac infarction, usually called myocardial infarction, is the medical term meaning heart attack. It is heart damage caused by lack of blood flow to the heart muscle.
Do cardiac enzymes remove dead tissue as a result of an infarction?
No, cardiac enzymes, such as CK, CKMB and troponin are proteins that help a cardiac cell function. When the cell is damaged, such as by a myocardial infarction, the cells die, and these proteins are liberated from the cell into the bloodstream where we can detect them and determine there has been cardiac cell death.
How would myocardial infarction affect cardiac output?
A myocardial infarction is a heart attack; during this, the heart's beat effectively stops and the heart is no longer pumping blood in any useable amount. Therefore, a myocardial infarction causes cardiac output to drop significantly and possibly drop to zero depending on the severity.
What has the author Shafie Fazel written?
Shafie Fazel has written: 'Cardiac repair and not regeneration after myocardial infarction'
What is the purpose of cardiac marker tests?
Cardiac marker tests identify blood chemicals associated with myocardial infarction (MI), commonly known as a heart attack.
Why do cardiac enzymes increase during a myocardial infarction?
cardiac enzymes encrease during myocardial infarction because its need decreases with death of portion of cardiac muscle. it is due to the inflammatory response of the body.
Where did the name myocardial infarction come from?
The myocardium refers to the main muscle layer of the heart. The word, infarction, refers to having suffered muscle damage due to lack of blood flow carrying needed oxygen to the cardiac muscle (myocardium). The common everyday term for myocardial infarction is "heart attack".
What is a myocardial infarction also known as?
Np. Angina refers to chest pain, such as from vasospasm of the coronary arteries, or from an impending myocardial infarction. The term, myocadial infarction, refers to cardiac muscle damage and death (a small MI involving a small area of the heart, and a large MI involving a larger portion of the heart).
