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.
Risk Factors
- Diabetes
- Obesity
- Family history of heart disease
- High blood pressure
- High low-density lipoprotein (LDL) cholesterol
- Low high-density lipoprotein (HDL) cholesterol
