Step-by-step explanation:
When CAD becomes symptomatic, it generally means that the condition is causing noticeable symptoms. The options provided in the question, a. Stable angina, b. Unstable angina, and c. Myocardial infarction, are all different levels of severity of symptoms that can occur in CAD. Stable angina is when pain is precipitated by exertion and improves quickly with rest or nitroglycerin. Unstable angina is when pain occurs during rest, lasts more than 15 minutes, and is of new onset. Myocardial infarction, commonly known as a heart attack, occurs when blood flow stops to a part of the heart, causing damage to the heart muscle. So, the correct answer is d. All of the above.
