A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]
[2] [3] Signs and symptoms often appear soon after the stroke has occurred. [3] If symptoms last less than 24 hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke.

[9] In unstable angina, symptoms may appear on rest or on minimal exertion. [6]
A cardiac stress test, puts stress on the heart through exercise. A series of exercises to measure the tolerance for stress on the heart will be carried out. This test uses an EKG to detect the electrical impulses of the heart during physical exertion. [29] A treadmill or exercise bike will be used.
