Final answer:
Variant (Prinzmetal) Angina is a type of angina characterized by episodes of chest pain caused by spasms in the coronary arteries. It can be triggered by factors such as stress, cold temperatures, or certain substances. Treatment involves medication and avoiding triggers.
Step-by-step explanation:
Variant (Prinzmetal) Angina is a type of angina, which is chest pain or pressure that occurs when heart muscle cells do not receive adequate blood flow and become starved of oxygen. Variant angina is characterized by episodes of chest pain that can occur at rest, usually during the night. Unlike other types of angina, variant angina is caused by spasms in the coronary arteries rather than a blockage caused by plaque buildup. These spasms can be triggered by various factors such as emotional stress, exposure to cold temperatures, or the use of certain substances like cocaine or certain medications. Treatment for variant angina involves medication to relax the coronary arteries and prevent spasms, as well as identifying and avoiding triggers.
