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.
What is the blood test performed to determine cardiac damage in an acute myocardial infarction is?
The blood test performed to determine cardiac damage in an acute myocardial infarction is called a cardiac enzyme test. This test measures levels of specific enzymes released into the bloodstream when heart muscle cells are damaged during a heart attack. The most commonly measured enzymes are troponin and creatine kinase-MB (CK-MB).
What are two tissues that is replaced largerly with scar tissue?
Two types of tissues that are largely replaced by scar tissue are cardiac muscle tissue and nervous tissue. In the heart, after a myocardial infarction (heart attack), damaged cardiac muscle is replaced by fibrous scar tissue, which does not contract or function like healthy muscle. Similarly, in the nervous system, injuries to neurons often result in scar tissue formation by glial cells, which inhibits regeneration and functional recovery.
What is it call when part of the heart dies and is damaged?
infarction
What acucurs in a myocardial infarction?
A myocardial infraction is occurs when both coronary thrombosis and coronary embolism , a blood clot occludes or plugs up some parts of the coronary artery. Blood can not pass through the occluded vessel and so cannot reach the heart muscle cells it normally supplies, it deprived of oxygen, and the cells soon become damaged.
What type of connective tissue is damaged when you lacerate your index finger?
Dense regular connective tissue
How do you fix a damaged crankshaft?
A damaged crankshaft will need replaced.A damaged crankshaft will need replaced.
What are the two types of tissue repair?
The two types of tissue repair are regeneration, where damaged tissue is replaced with new functional tissue, and fibrosis, where damaged tissue is replaced with scar tissue made of collagen fibers. Regeneration is ideal as it restores normal tissue function, while fibrosis can lead to loss of function depending on the extent of scarring.
If a myocardial infarction damaged the left bundle branch how would this affect the spread of the action potential?
Ventricular depolarization takes longer because impulses in the left ventricle must travel from cell to cell rather than traveling down the left bundle branch and Purkinje fibers. (This will lead to a longer QRS complex on an ECG)
What type of connective tissue is damaged when you lacerate your index finger tendon?
When you lacerate your index finger tendon, the type of connective tissue that is damaged is the tendon itself. Tendons are dense connective tissues that connect muscles to bones, and they play a crucial role in transmitting the force generated by muscles to produce movement.
What thrombosis is damaged to the heart muscles caused by thrombus blocking a coronary artery?
Myocardial infarction, commonly known as a heart attack, is the condition where the heart muscles become damaged due to the blockage of a coronary artery by a thrombus. This obstruction leads to a lack of oxygen-rich blood flow to the heart, resulting in tissue damage. Immediate medical attention is necessary to limit the extent of damage and prevent potential complications.
What happens to the heart from lack of oxygen?
Lack of oxygen to the heart can lead to chest pain (angina) or a heart attack (myocardial infarction). Without enough oxygen, the heart muscle can become damaged, leading to potential complications such as arrhythmias or heart failure. Immediate medical attention is necessary to address the underlying cause and prevent further damage to the heart.
