Prinzmetal's angina, otherwise known as variant angina, is a rare form of this condition that typically occurs in younger people. It is caused by a spasm in a coronary artery, which narrows the artery and causes reduced blood flow to the heart. Common symptoms of Prinzmetal's angina include severe chest pain, nausea, and fatigue. Treatment for the condition generally involves medication, such as nitroglycerin.
