Ischemia to heart muscle occurs which can lead to
1. Angina pectoris (chest pain)
2. Sudden death (loss of blood supply)

Other symptoms
1. Epigastric distress (sharp, gnawing, dull)
2. Pain radiation to jaw/left arm
3. SOB (in those with diabetes and heart failure)
4. Women report: Nausea, indigestion, palpitations and numbness

Second part:
1. CAD produces symptoms and complications according to the location and degree of narrowing of the arterial lumen, thrombus formation and obstruction of blood flow to the myocardium.

2. The progressive loss of blood flow through the coronary arteries causes an inadequate blood supply to be delivered to the heart muscle when there is insufficient blood going to the heart muscle, there is insufficient oxygen being delivered to the heart muscle, impacting the heart muscle survival.
Ischemia is the term used to describe the lack of blood and oxygen in tissues, and in this case its the heart.

3. When heart muscle is starved of oxygen (ischemia) it is experienced as chest pain (angina)

4. If the decrease in blood supply is great enough, or long enough duration or both irreversible damage and death of myocardial cells may result.

5. Over time a irreversible damage myocardium undergoes degeneration and is replaced by scar tissue, causing various degrees of myocardial dysfunction.

6. Significant myocardial damage may result in persistently low CO and heart failure where the heart cannot supply the body's needs for blood. A decrease in blood supply from CAD may cause the heart to abruptly stop
