What is Unstable Angina?

Unstable angina is chest pain that happens suddenly and becomes worse over time. It occurs seemingly without cause. It can happen when you’re at rest or even asleep. An attack of unstable angina may lead to a heart attack. For this reason, an attack of unstable angina is an emergency and you should seek immediate medical treatment.

Unstable angina is a signal that your arteries are becoming very narrow and that you could experience a heart attack. If left untreated, unstable angina can lead to heart attack, heart failure, or arrhythmias (irregular heart rhythm). These can be life-threatening conditions.

Causes

Coronary heart disease caused by a buildup of plaque along the walls of your arteries is the primary cause of unstable angina. The plaque causes your arteries to narrow and become rigid. This constricts blood flow to your heart muscle. When the heart muscle doesn’t have enough blood and oxygen, you feel chest pain.
