Final answer:
The patient experiences chest pain due to angina, which is pain caused by reduced blood flow and lack of oxygen to the heart muscle during exertion and is typically relieved by rest. There are two types, stable angina and unstable angina, with the latter requiring immediate medical attention.
Step-by-step explanation:
The chest pain described by the patient, which occurs intermittently during exertion and is relieved by rest, is likely caused by a condition known as angina.
Angina and Its Mechanisms
Angina is a type of chest pain caused by reduced blood flow to the heart muscle, usually due to partial blockage of the coronary arteries by the buildup of plaque. When the heart muscle does not receive enough oxygen, a situation called ischemia arises, which results in pain or discomfort. This can happen during physical activities that increase the heart's demand for oxygen and nutrients.
Classification of Angina
Stable angina is a form of angina that presents as chest discomfort or pressure triggered by physical exertion and is typically relieved within minutes by rest or medications like nitroglycerin. On the other hand, unstable angina is a more severe form, characterized by pain that occurs even at rest or that lasts longer than 15 minutes. Unstable angina requires immediate medical attention as it may indicate an impending heart attack. It is important for this patient to seek clinical evaluation to manage symptoms and prevent potential progression to more severe conditions.
