Symptoms of Prinzmetal's angina include chest pain, nausea, fatigue or shortness of breath that occurs specifically when an individual is at rest, according to Mayo Clinic. The attacks are often severe and usually occur at night or early in the morning, as stated by the American Heart Association.
Prinzmetal's angina is an extremely rare type of angina which is caused by reduced blood flow to the heart, states Mayo Clinic. The result is often pain, described as a squeezing, tightness or heaviness in one's chest. Prinzmetal's angina is more commonly found in younger people than other forms of angina, states the American Heart Association. Treatment with medicine is usually effective, and after six to 12 months, the doctor may recommend a lower dose of medicine.
