What is a common complication associated with Prinzmetal angina?

Prinzmetal angina, also known as variant angina, is characterized by episodes of chest pain caused by transient spasms of the coronary arteries. This type of angina can occur at rest, often during periods of stress or in response to certain triggers such as smoking or exposure to cold. The spasms reduce blood flow to the heart temporarily, leading to ischemic chest pain.

The correct answer highlights that a common complication associated with Prinzmetal angina is the occurrence of arrhythmias and chest pain at rest. The transient nature of the myocardial ischemia caused by coronary artery spasm can lead to abnormal heart rhythms (arrhythmias), which can be serious and potentially life-threatening. Additionally, individuals may experience chest pain even while at rest, differentiating this type of angina from typical exertional angina, where pain occurs with physical activity.

The other options do not align with the typical complications of Prinzmetal angina. Progression to congestive heart failure is more commonly associated with chronic ischemic heart disease rather than the episodic nature of Prinzmetal angina. Heart valve disease is a separate cardiovascular issue that does not stem from coronary artery spasms. Similarly, while coronary artery blockages can contribute to various types of
