The word infarction means that some area of tissue has died due to a lack of blood flow, and therefore a lack of oxygen. “Myo” refers to the muscle, and “cardial” refers to the heart tissue. So with a heart attack, or MI, you have death of heart muscle cells because of a lack in blood flow, a process called necrosis.
The myosin-binding protein C, cardiac-type is a protein that in humans is encoded by the MYBPC3 gene. [5] This isoform is expressed exclusively in heart muscle during human and mouse development, [6] and is distinct from those expressed in slow skeletal muscle and fast skeletal muscle .
Myocardial infarction (MI) refers to tissue death of the heart muscle caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome , which describes a sudden or short-term change in symptoms related to blood flow to the heart. [ 22 ]
Sarcopenia (ICD-10-CM code M62.84 [1]) is a type of muscle loss that occurs with aging and/or immobility. It is characterized by the degenerative loss of skeletal muscle mass, quality, and strength. The rate of muscle loss is dependent on exercise level, co-morbidities, nutrition and other factors.
Chest pain due to coronary ischemia commonly radiates to the arm or neck. [7] Certain individuals such as women, diabetics, and the elderly may present with more varied symptoms. [8] If blood flow through the coronary arteries is stopped completely, cardiac muscle cells may die, known as a myocardial infarction, or heart attack. [9]
Adenosine monophosphate deaminase deficiency type 1 or AMPD1, is a human metabolic disorder in which the body consistently lacks the enzyme AMP deaminase, [1] in sufficient quantities. This may result in exercise intolerance, muscle pain and muscle cramping. The disease was formerly known as myoadenylate deaminase deficiency (MADD).
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart .
Cysteine and glycine-rich protein 3 also known as cardiac LIM protein (CLP) or muscle LIM protein (MLP) is a protein that in humans is encoded by the CSRP3 gene. [5] CSRP3 IS a small 194 amino acid protein, which is specifically expressed in skeletal and cardiac muscle. [6] [7] In rodents, CSRP3 has also been found to be expressed in neurons. [8]
