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.

Inflammation factors released during acute MI stimulate the release of granulocyte and monocyte precursors in the bone marrow which in turn promotes proliferation = leukocytosis

What is the blood test performed to determine cardiac damage in an acute myocardial infarction is?

Cardiac enzymes


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.


When a myocardial infarction occurs what substance is released into the blood stream?

myocardial band enzymes


What is the significance of a slightly elevated creatine kinase blood test presumed not cardiac related?

cpk enzymes are found in cardiac muscle, skeletal muscle and the brain, cpk will be elevated 10 to 25 times the normal level following a myocardial infarction, they will also be elevated after a trauma to skeletal muscle and in progressive muscular dystrophy, cpk can be elevated after strenuous exercise.


How is ESR affected by myocardial infarction?

The ESR (or sedimentation rate) is a marker for acute inflammation. In the case of a myocardial infarction it is typically elevated within 3 days of the infarction and may remain elevated for weeks after.

Cardiac enzymes and troponin elevate what?

Cardiac enzymes and troponin levels do not elevate anything. Rather, when you have a heart attack (MI), they are elevated. Unlike damage to any other muscle in your body, damage to the cardiac muscle causes the release of specific cardiac enzymes. Therefore, if they are elevated, you had damage to your heart (i.e. heart attack). I disagree with the above: If both are elevated then you may have had a heart attack but, if cardiac enzymes alone are elevated and not troponin levels then you will not have had a heart attack. That's my personal experience. Troponin levels are now considered a more accurate indicator of damage to the heart muscle as a result of a heart attack than cardiac enzymes which can apply to any other muscle group rather than the heart. In fact to use the word 'cardiac' in this context is misleading because if you sprain your ankle for instance 'cardiac' enzymes will be released into the blood! So, where is the connection between damage to your ankle and that of your heart? Both enzymes therefore need to be elevated to indicate heart damage reliably.


What is the role of a cardiac enzyme?

Cardiac enzymes (also known as cardiac markers) are a substance released into the blood when one has heart problems, they help doctors diagnose if someone has had a heart attack.


IS it true that enzymes increase the number of collisions in a chemical reaction?

No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.


Cardiac enzymes are drawn in what color of top tube laboratory?

What are enzymes considered?

Enzymes are considered to be catalysts; they increase the rate of a chemical reaction.


What are enzymes and can you have a simple answer please?

Enzymes are proteins that increase the rate of chemical reactions.


What enzymes are present in human bodies?

There is a huge amount of enzyme types in the human body. We have digestive enzymes such as pepsinogen, cardiac enzymes such as Trop-I, liver enzymes such as GGT. If you are curious of enzymes in the human body I suggest you look at specific systems or organs. An example would be to ask the internets about "pancreatic enzymes".
