Answer:

1. ''Chest pain is caused by tissue hypoxia in the myocardium''.

Step-by-step explanation:

Myocardial infarction (MI) refers to the irreversible damage of the heart tissue occurring due to prolonged ischemia. Ischemia is a condition which affects the heart due to reduced blood flow to the myocardium and as a result prevents the heart muscles from receiving enough oxygen and referred to as tissue hypoxia. This lack of oxygen thereby leads to the death of the myocardial cells.

The most prominent symptoms of myocardial infarction is chest pain. Other symptoms that maybe experienced include; sweating, shortness of breath and severe weakness.
