Angina itself is not a disease, rather a symptom of an underlying heart problem. Angina is usually a symptom of coronary heart disease, the most common heart disease.
What is Angina?
Angina is chest pain or discomfort that occurs when an area of your heart muscle doesn't get enough oxygen-rich blood.
Types of Angina : There are three types of angina; they are stable, unstable, and variant, they have separate symptoms and need different treatments.
Stable Angina
Stable angina is the most common angina, occurs when the heart is working harder than normal. It has a regular pattern, so learn to predict when the pain will occur. Stable angina itself is not a heart attack, but it is more likely it may cause a heart attack in the future.
The pain usually goes away in a few minutes after taking rest or angina medication.
Unstable Angina
Unstable angina has no pattern, so difficult to predict when it occurs. It can occur with or without physical exertion. Rest or medicine will not relieve the pain.
Unstable angina is very dangerous and needs emergency treatment. It is advance notice to be a heart attack.
Variant Angina
Variant angina is rare angina, usually occurs while at rest. The pain can be severe, happens between midnight and early morning, pain relieved by medicine.
Not all cases of chest pain or discomfort are angina. A lung problem, heartburn, or a panic attack can also cause chest pain or discomfort similar to angina.
Angina is otherwise call as Angina pectoris, acute coronary-syndrome, chest-pain, coronary artery spasms, stable angina, common angina, unstable angina, and variant angina.
