Causes of angina
Some possible triggers of stable angina include exposure to very hot or cold temperatures and/or heavy meals. Other causes of spasms in the coronary arteries include:

• cocaine use
• exposure to cold
• emotional stress
• medicines that tighten or narrow blood vessels
• smoking

Risk factors
Angina is a symptom of an underlying heart condition, usually coronary artery disease (CAD). So if you're at risk for CAD, you're also at risk for angina. Risk factors for CAD include:

• age (men 45+ and women 55+)
• cigarette smoking
• family history of early heart disease
• high blood pressure
• insulin resistance or diabetes
• lack of physical activity
• metabolic syndrome
• overweight or obesity
• unhealthy cholesterol levels
