Quick read
Key points
- 1
Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to narrowed arteries from a build-up of fatty deposits. It typically occurs during exertion or stress, when the heart needs more oxygen than the narrowed arteries can supply, and usually eases with rest.

01 · Know
What is Angina?
Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to narrowed arteries from a build-up of fatty deposits. It typically occurs during exertion or stress, when the heart needs more oxygen than the narrowed arteries can supply, and usually eases with rest.
Angina is a symptom of underlying coronary heart disease, and while not itself a heart attack, it signals an increased risk of one. With the right combination of medication and lifestyle changes, most people manage angina well and reduce their risk of more serious problems.
02 · Understand
Clinical context
Know the difference between stable angina and a heart attack
Typical angina eases with rest or prescribed medication within a few minutes — pain that doesn't ease, or that feels different from usual, could indicate a heart attack and needs emergency care immediately.

Practical steps
Always Carry Prescribed Angina Medication
If you've been prescribed medication such as a GTN spray for angina episodes, always carry it with you and use it as directed when symptoms start.
- 1Take medication as prescribed.This includes both regular preventive medication and any medication used during an angina episode.
- 2Rest immediately when angina symptoms start.Stopping activity and resting often eases symptoms within a few minutes.
- 3Manage cardiovascular risk factors.This includes stopping smoking, managing blood pressure and cholesterol, and staying physically active as advised by your doctor.
- 4Pace physical activity.Understanding your triggers and building up activity gradually, as guided by your care team, supports heart health without overexertion.
- 5Know when to seek emergency care.Symptoms that don't ease with rest or medication, or feel different from usual, need immediate assessment.

BarnMD Bottom Line
Angina is a manageable symptom of coronary heart disease, and most people control it well with medication and lifestyle changes.
Chest pain that doesn't ease with rest or prescribed medication should always be treated as a possible heart attack — seek emergency care immediately.
