Explanation / Answer

Myocardial infarction occurs because of reduced flow of blood to the heart muscles causing damage to them. It may be caused because of blockage in the coronary artery. So Mr. Jones was first given aspirin which reduces blood clots and clears the passage for blood flow, then he was put on oxygen as an initial treatment so that the oxygen deprived heart muscles get oxygen for functioning.

Isotonic saline does not change the tonicity of the blood but increase the blood volume (intravascular compartment). Isotonic saline in intracellular compartment will increase the fluid volume and movement of water fron ICF to ECF will take place.

Cardiac enzyme Creatine kinase level increases patients having myocardial infarction. During Myocardial infarction troponin molecules, a component of the muscle fibre, are released from damaged myocytes. That is why the troponin level is elevated during Myocardial infarction.
