Signs of Angina
Angina is chest pain that occurs when the blood supply to the muscles of the heart is restricted. It usually happens because the arteries supplying the heart become hardened and narrowed. The pain is usually triggered by physical activity or stress and typically only lasts for a few minutes. This is often referred to as an angina attack.
Symptoms of angina
The most common symptom of angina is a feeling of pain or discomfort in your chest. The pain can feel tight, dull or heavy. The pain can spread from your chest to your left arm, neck, jaw and back. In some cases, the pain is similar to indigestion.
Chest pain may also occur with:
• feeling sick (nausea)
• feeling unusually tired
Some people may experience breathlessness without any obvious chest pain.
There are two types of angina, called stable and unstable angina. The symptoms of these two types are similar, but there are some important differences.
Attacks of stable angina usually occur when the heart is forced to work harder – for example, during physical activity or emotional stress. In some cases, the pain can also develop after eating a meal or during cold weather. These are known as angina triggers. The symptoms of stable angina usually improve if you rest for a few minutes.
Unstable angina is more unpredictable. It can develop without any obvious triggers and can persist even when you’re resting. Attacks of unstable angina may last longer than a few minutes and don’t always respond to treatments used for stable angina.
When to seek medical help
Dial 999 to request an ambulance if you experience chest pain and you haven’t previously been diagnosed with a heart problem.
If you have an angina attack and you’ve previously been diagnosed with the condition, take the medication prescribed for you (glyceryl trinitrate). A second dose can be taken after five minutes if the first dose doesn’t have any effect. If there’s no improvement five minutes after the second dose, call 999 and ask for an ambulance.
