Angina is a type of chest pain or discomfort that happens when your heart muscle doesn't get enough oxygen-rich blood. It is often a symptom of coronary artery disease, where the blood vessels that supply your heart become narrowed or blocked. The tests for angina help doctors find out how well your heart is working and what might be causing the pain.
Key facts
Angina is common, especially in people over 50. It affects millions of people worldwide. It is more common in men, but after menopause the risk for women increases.
Angina mainly affects people who have risk factors for heart disease, such as high blood pressure, high cholesterol, smoking, diabetes, or a family history of heart problems. It is more common in older adults, but younger people can also get it.
Doctors diagnose angina by first talking to you about your symptoms and your health history. They will then do a physical exam and likely order several tests to look at your heart. The tests help find out if your chest pain is from your heart and how serious it is.
Treatment for angina focuses on relieving symptoms, slowing the progression of heart disease, and preventing heart attacks. Treatment may include lifestyle changes, medicines, and sometimes procedures. Your doctor will tailor a plan to your specific situation. Never change or stop your treatment without talking to your healthcare provider.
Living with angina means learning to manage your symptoms and take care of your heart. Keep a diary of when symptoms occur, what you were doing, and how long they last — this helps your doctor adjust your treatment. Carry your medicines with you, especially if you have a short-acting angina spray or tablet. Learn to pace yourself: take breaks during physical activity, and avoid heavy meals or sudden exertion. With proper treatment, most people with angina can lead a full and active life.
You cannot always prevent angina, especially if you have a strong family history. However, the same lifestyle changes that treat angina can also help prevent it. Keeping your blood pressure, cholesterol, and blood sugar in a healthy range is very important. Not smoking, eating well, staying active, and managing stress all reduce your risk. The earlier you start, the better.

Most tests for angina are done as an outpatient — you can go home the same day. Some tests like a coronary angiography may require an overnight stay. The tests are generally safe. Your doctor will explain each test to you before it happens and tell you how to prepare (for example, not eating for a few hours before some tests). You may feel a bit anxious, but the tests are routine and the medical team will take good care of you.
Doctors may prescribe medicines to help prevent angina attacks and reduce the workload on your heart. These can include medications that widen blood vessels (like nitrates), lower blood pressure, slow the heart rate, or reduce cholesterol. You may also be given low-dose aspirin or other blood thinners to prevent clots. Always talk to your doctor or pharmacist before taking any new medicine, including over-the-counter products.
When lifestyle changes and medications are not enough, doctors may recommend a procedure to improve blood flow to the heart. This could be a procedure like angioplasty (using a balloon to open a blocked artery, often with a stent placed to keep it open) or coronary artery bypass surgery (using a blood vessel from another part of your body to bypass the blockage). Your doctor will discuss the risks and benefits based on your specific condition.
A heart-healthy diet is key. Eat plenty of fruits, vegetables, whole grains, and fish. Choose lean meats and low-fat dairy. Limit foods high in salt, sugar, and unhealthy fats (especially trans fats). For exercise, low-impact activities like walking, swimming, or cycling are often safe if you start slowly and build up. Always check with your doctor before starting an exercise program.
Angina can cause anxiety, fear of another attack, and worry about your health. It is normal to feel stressed or down. Talk to your doctor or a counselor if you are struggling. Many people find support groups helpful. If you have thoughts of harming yourself, contact a crisis helpline immediately.
The outlook for people with angina is generally good with proper treatment and lifestyle changes. Many people with angina live long, active lives. The key is to work closely with your healthcare team, take your medicines as prescribed, and be aware of changes in your symptoms. Angina can be a warning sign, but with modern treatments, you can reduce your risk of serious complications. Staying positive and proactive makes a big difference.
