What condition is characterized by intermittent chest pain relieved by nitroglycerin with normal coronary arteries?

• A. Stable angina
• B. Prinzmetal angina
• C. Unstable angina
• D. Myocardial infarction

Answer: (B)

The condition characterized by intermittent chest pain that is relieved by nitroglycerin in the presence of normal coronary arteries is Prinzmetal angina, also known as variant angina. This type of angina is caused by spasms of the coronary arteries that reduce blood flow to the heart muscle, leading to episodes of chest pain. Notably, these spasms can occur at rest and may be triggered by stress, cold exposure, or smoking. The pain associated with Prinzmetal angina is typically relieved quickly with nitroglycerin, which acts as a vasodilator, relaxing and widening the blood vessels, thereby alleviating the pain caused by transient reductions in blood flow. The absence of significant coronary artery disease on angiography is crucial for the diagnosis, as it distinguishes Prinzmetal angina from other forms of angina that are secondary to atherosclerotic disease. In contrast, stable angina is generally provoked by physical exertion or emotional stress and occurs when there is a fixed coronary artery obstruction. Unstable angina involves a change in the pattern of chest pain, often occurring at rest or with increased frequency and intensity and is associated with a higher risk of myocardial infarction. Myocardial infarction results from a complete blockage
