Angina differs from a heart attack because the reduction in blood flow to the heart muscle is only temporary and does not result in damage to the heart muscle.
During a heart attack, the interrupted blood flow can result in the heart muscle being damaged or destroyed. People with angina, however, are at higher risk of having a heart attack.
If you have been diagnosed with angina and you experience unstable angina or angina pain that is unusual or unexpected e. You should dial immediately and ask for an ambulance. Angina symptoms are not always present because during times of low oxygen demand, e. Signs and symptoms of angina include:.
The severity, duration, and type of angina can vary. It is important to recognise new or different symptoms since they may signal unstable angina, or a heart attack. In some cases women with angina may not experience classic chest pressure or discomfort symptoms, and this can lead to delays in seeking treatment.
A doctor will conduct a physical examination and discuss your symptoms and risk factors such as body weight, smoking, diabetes, blood pressure and cholesterol levels and your family history of heart disease.

About heart conditions — angina Angina also known as angina pectoris, which in Latin means 'squeezing of the chest' is a temporary discomfort or pain that happens when part of your heart muscle is temporarily not able to get enough blood and oxygen to meet its needs.
Symptoms of angina The pain or discomfort associated with angina usually feels tight, gripping or squeezing, and can vary from mild to severe. If angina symptoms last longer than 10 minutes, call triple zero for an ambulance. Common triggers of angina Angina attacks can be prompted by exertion or physical exercise, when the hard-working heart muscle requires greater amounts of oxygen.
Other triggers of angina may include: high emotion, such as anger or excitement cold temperatures eating a large meal. Unstable angina Angina pain usually occurs with physical activity and goes away after a few minutes of rest. Risk factors for angina Over time, the coronary arteries are narrowed by a layering of fatty deposits plaques in the inner linings of the artery walls.
Diagnosis of angina Angina is diagnosed using a number of tests, including: exercise stress test — the heart is monitored using a device called an electrocardiogram ECG while you ride a stationary bicycle or walk on a treadmill. The test is halted once angina chest pain is triggered cardiac catheterisation angiogram — a tube, or catheter, is threaded into the coronary arteries via a blood vessel in the groin.
A special dye is then injected into the coronary artery. Your heart coronary arteries can become narrowed by fatty deposits called plaques.
This is called atherosclerosis. During times of low oxygen demand — when you're resting, for example — your heart muscle may still be able to function on the reduced amount of blood flow without triggering angina symptoms.
But when you increase the demand for oxygen, such as when you exercise, angina can result. Unstable angina. If fatty deposits plaques in a blood vessel rupture or a blood clot forms, it can quickly block or reduce flow through a narrowed artery.
This can suddenly and severely decrease blood flow to your heart muscle. Unstable angina can also be caused by blood clots that block or partially block your heart's blood vessels. Unstable angina worsens and isn't relieved by rest or your usual medications. If the blood flow doesn't improve, your heart is starved of oxygen and a heart attack occurs.
Unstable angina is dangerous and requires emergency treatment. The chest pain that occurs with angina can make doing some normal activities, such as walking, uncomfortable. However, the most dangerous complication is a heart attack. You can help prevent angina by making the same lifestyle changes that might improve your symptoms if you already have angina.
