It is a symptom of an underlying heart condition, usually coronary heart disease. to the heart muscles, due to a build-up of a fatty substance in the arteries (plaque).

Stop and rest immediately

If rest doesn’t relieve your symptoms, take one dose of your angina medicine (available in a spray or dissolvable tablet form). Sit or lie down before taking your medicine, because it can make you feel dizzy. Take the smallest dose that works for you (e.g.

Ask for an ambulance and don’t hang up – then wait for advice from the operator

Angina can stop and start, and episodes of angina can last anywhere from seconds to minutes. It often happens when your heart is working harder than usual and needs more oxygen-rich blood than the narrowed arteries can deliver. Common triggers of angina include: eating a large meal.

There are different types of angina including: microvascular angina. Stable angina is usually triggered by physical exertion or emotional stress.

The symptoms often go away after a few minutes of rest

It can also be relieved by angina medicine

Unstable angina can occur anytime, and often happens while resting. The symptoms may not improve with rest or medicine and can last longer than stable angina. Vasospastic angina is also known as Prinzmetal angina or variant angina.

This type of angina is rare and often severe but can be relieved with medicines. It can happen while resting when spasms in the coronary arteries supplying blood to the heart cause them to narrow or tighten. Microvascular angina, also known as cardiac syndrome X, may be a symptom of coronary microvascular disease (MVD).

Coronary MVD is a heart disease that affects the smallest blood vessels of the heart. The pain or discomfort can be more severe and can last longer than stable angina. There are several risk factors that can increase your risk of coronary heart disease and angina, including: ethnicity – people of certain ethnic backgrounds, including Aboriginal and/or Torres Strait Islander Peoples have increased risk of coronary heart disease.

To diagnose angina, your doctor will review your symptoms, ask about your family history of heart disease and conduct a physical examination. Your doctor may also perform one or more of the following tests: – the heart is monitored using an ECG while you ride a stationary bike or walk on a treadmill.

The test will stop if you experience angina (chest pain).

– This is where a long, thin tube (catheter) is inserted into an artery in your wrist (or sometimes the groin). The catheter is threaded through the artery until it reaches your heart. A special dye is then injected into the catheter and an is taken.

The X-ray shows where the coronary arteries are narrowed or blocked from a build-up of plaque.

Angina treatment reduces the frequency and severity of symptoms

It also lowers your risk of a heart attack by treating other underlying conditions.

Angina can be treated and managed with medicines, lifestyle changes and surgery. Nitrate medicines (for example, glyceryl trinitrate or GTN) are commonly prescribed to widen your blood vessels and increase blood flow to your heart.

These are available in many forms including a spray or patches

Some nitrate medicines are used to relieve angina, whilst others are taken every day as a preventative measure.

If you have coronary heart disease, you may also need to take other medicines to reduce your risk of a heart attack. These can include:

  • Always take your medicines as prescribed by your doctor to help prevent
  • treat manage angina
  • lower your risk of further heart problems

Making lifestyle changes can help to prevent angina and reduce your risk of a heart attack. They include:

  • managing your blood sugar levels
  • for people with diabetes. if medicines or lifestyle changes are not helping to relieve their angina symptoms

The two main types of surgery for angina are:

  • a procedure to open up a narrowed or blocked coronary artery using a balloon. Once the artery is open
  • a special expandable wire mesh tube (stent) is left in place to keep it open
  • the balloon is withdrawn

This improves blood flow to your heart

– an operation where a healthy blood vessel (can be a vein or artery from your arm, leg or chest) is attached to either side of the blocked artery in your heart and is used to allow blood flow to your heart again. Taking medicines as prescribed and making changes to your lifestyle can lower your risk of worsening angina and from developing further complications, including a heart attack. and stress in some people.
