myocardial

pertaining to the muscular tissue of the heart (the myocardium).

myocardial asthenia

myocardial weakness and decrease in the power of the heart's contraction, leading to reduction in cardiac reserve and ultimately to congestive heart failure.

myocardial cells

1. being surrounded by an intact sarcolemma prevents the cells forming a true syncytium; but do form a functional syncytium because of presence of gap junctions with low electrical resistance which allow the passage of ions and small molecules.

2. myocardial cells are specialized smooth muscle cells with acquired features and properties similar to those of skeletal muscles.

myocardial contractility

myocardium has an intrinsic periodic contractility which enables the denervated heart to continue beating; in the intact animal neurogenic control of contractility is paramount, inhibited by parasympathetic effects, stimulated by sympathetic effects.

myocardial damage

any disease causing loss of muscular or nervous function of the heart. Includes myocarditis, ischemia, degeneration.

myocardial depressant factor

substances liberated from the pancreas, intestine and liver during any type of circulatory shock. They reduce cardiac and reticuloendothelial activity and cause vasoconstriction. Called also MDF.

myocardial dystrophy

degenerative change in heart muscle, e.g. that occurring as a result of nutritional deficiency of selenium or vitamin E. Death usually occurs suddenly, with blood-stained froth pouring from the nostrils.

myocardial fiber

see myocardial cells (above).

myocardial heart failure

heart failure due to myocardial inefficiency.

myocardial hypertrophy

increase in size of myocardial muscle due to increase in size of individual myocardial cells, usually in response to an added afterload.

myocardial infarction (MI)

necrosis of the cells of an area of the heart muscle (myocardium) occurring as a result of oxygen deprivation, which in turn is caused by obstruction to the blood supply; commonly referred to in humans as a 'heart attack'. This is not a common disease in animals, but does occur, e.g. in horses, especially in the right atrium. It is a cause of myocardial weakness. See myocardial asthenia (above).

myocardial inflammation

see myocarditis.

myocardial injury

see myocardial damage (above).

ischemic myocardial necrosis

localized or widespread necrosis due to interruption of the blood supply via the coronary arteries.

myocardial lipofuscinosis

occurs in aged or cachectic cattle, also in healthy cattle; most common in Ayrshires; no apparent significance in terms of health; called also brown atrophy.

myocardial necrosis

focal or massive and subsequent scarring caused by infection, e.g. Histophilus somni, the encephalomyocarditis virus, nutritional deficiency, e.g. vitamin E-selenium, poisoning by plants, e.g. Acacia georgina, farm chemicals, e.g. monensin, and ischemic necrosis due to general or local inadequacy of blood supply to the myocardium.

myocardial tension

affects myocardial contractility but the importance of the effect in the living animal is obscure.

Patient discussion about myocardial tension.

Q. I have hypertrophic cardiomyopathy and an ICD. Is it possible to get breast implants with an ICD? I have no further symptoms: I workout and run 6 days a week, in good shape and only 27 years old.

A. Some medical equipment can damage your ICD If you are visiting your doctor , tell him or her that you have an ICD BEFORE they do any testing or treatment.i'm pretty sure they'll find a creative way to do the implant.any way- before doing any procedure- ask the cardiologist that handles you about it.
