Cardiac arrest occurs when the heart stops beating (or arrests). When a myocardial infarction (MI) occurs a portion of the heart either dies or becomes ischemic. Usually arrest wouldn't be due to an MI but if an MI was big enough it would initiate an arrhythmia called fibrillation and the heart would stop pumping blood. This is also called sudden cardiac death. SCD can occur without an MI as well.

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.
Why heart failure occur?
The briefest medical explanation for the occurrence of cardiac failure is the result of two completely different viruses or infections are present at once, resulting in not heart attacks but failure of the hearts valves causing cardiac arrest.
Myocardial infarctions result from?
Myocardial Infarctions, or heart attacks, can be caused by obesity. A fatty diet or lack of regular exercise can lead to a higher chance of a myocardial infarction.
How is cardiac cycle affected by MI?
Myocardial infarction (MI) can disrupt the normal cardiac cycle by causing damage to the heart muscle, leading to impaired contraction and relaxation. This can result in diminished cardiac output, arrhythmias, and heart failure. The severity of these effects depends on the location and extent of the heart damage.
What is the meaning of acute myocardial?
Acute myocardial ischemia happens when the coronary artery gets blocked. As a result the blood and the oxygen supply to the heart reduces and the heart muscles can not work properly. This means heart fails to pump efficiently leading to a cardiac arrest.
What is the differential diagnosis of elevated creatinine phosphokinase?
increased cpk may result to myocardial infarction, Dystrophies, myocardits and the likes
What can happen when the heart muscle does not get enough blood?
Myocardial ischemia results from the temporary lack of oxygen; if ischemia is prolonged, it could result in permanent damage to the heart muscle. This condition is called myocardial infarction, commonly known as a heart attack.ischemia
Differentiate myocardial ischemia from myocardial infarction?
Ischaemia is the lack of blood supply to a tissue which start anaerobic respiratory mechanisms. Infarction is cell death through apoptosis resulting from prolonged or severe ischaemia. Clinicaly myocardial infarction will be more painful and is unrelieved by rest. On ECG infarction will reult in ST segment elevation where ischaemia will result in ST segment depresion (unless it is a posterior MI!). In MI there will also be raised biochemical markers hours later such as creatine kinase and troponin.
High level of which ion will result into cardiac arrest?
Potassium (K+)
What does nil acute mean on a e c g result?
"Nil acute" on an ECG result indicates that there are no acute changes or abnormalities detected at the time of the reading. This suggests that there are no signs of recent myocardial infarction (heart attack), ischemia, or other urgent cardiac issues. Essentially, the heart's electrical activity appears normal and stable at that moment.
What is the difference between SCD and a heart attack?
A heart attack (myocardial infarction) is the result of a blockage in an artery which feeds the heart, so the heart becomes starved for oxygen.
What are the sign and symptoms of respiratory arrest?
complete shut down of the respiratory system. respiratory arrest is the ultimate result of prolonged respiratory failure. respiratory arrest usually results in cardiac arrest. (in children)
