Final answer:
Anginal is an adjective describing symptoms associated with angina, which is chest pain resulting from inadequate oxygen to the heart due to reduced blood flow in narrowed coronary arteries.
Step-by-step explanation:
The term anginal refers to symptoms related to angina, which is a type of chest pain or discomfort caused by reduced blood flow to the heart muscle, resulting in insufficient oxygen delivery. Angina itself is often a symptom of coronary artery disease, a condition that involves the buildup of plaque within the walls of the coronary arteries leading to their narrowing.
There are different types of angina: stable angina, which commonly occurs with exertion and eases with rest or medication like nitroglycerin; and unstable angina, which is a more severe form that occurs while at rest, is longer lasting, and may indicate a higher risk of a heart attack.
