Angina can be described as chest pain or discomfort that comes as a result of an area of the heart muscle not getting enough blood that is rich in oxygen. Most patients report feeling a squeezing or pressure in their chests. The pain may also be felt in the arms, shoulders, neck back or jaw. At times the pain may feel like indigestion. Angina itself is not a disease but an indication of an underlying disease such as coronary heart disease.
There are several types of angina that are known. The first one is stable angina which is the most common type. It is usually a result of the heart working harder than it is used to. It has a specific pattern that can help you to predict when the next pain will occur. The pain only lasts a few minutes after you take your medicine or after you take a rest. This however should not be confused with a heart attack but it is a sign that a heart attack may happen soon. Unstable angina on the other hand has no particular pattern. It can occur more times and is more severe than stable angina. This kind of angina can require immediate treatment because of its severity. Variant angina on the other hand is very rare and is caused by a spasm in the coronary artery. The pain can be quite sever and occurs when someone is resting. The likely times that it happens are between early morning and midnight. Micro vascular angina on the other hand lasts longer than the previously described anginas and is more severe. Medicine may not relieve the pain that comes with angina.
