Answer:
Option 1, heart attack
Explanation:
A myocardial infarction (MI) occurs when blood flow through the coronary arteries that supply blood to the heart becomes obstructed, either due to atherosclerosis, thromboembolism, and or hemodynamic changes. This affects the ability for the heart muscle, known as the myocardium, to receive the oxygen and nutrients it needs to continue contracting, pumping blood from the ventricles out to the lungs and the peripheral tissues. Due to this ischemia, the heart muscle begins to necrose, which is known as infarct.
The patient begins to exhibit clinical manifestations such as left shoulder pain, neck and jaw pain, feelings of indigestion, and chest pain that may or may not be relieved with medications like nitroglycerin.
It will feel like their heart is under attack, hence why MIs are commonly referred to as heart attacks, option 1.
