What is an unstable angina?

chest pain that occurs due to lack of blood flow to the heart is called angina; When the level, frequency and duration of pain and duration increases and becomes unpredictable, it is known as unstable angina. The key difference between stable and unstable angina is that a stable variety is usually initiated by a known trigger such as stress or exercise, while an unstable type can take place at any time for a specific reason. People whose angina changes from stable to unstable should concern and can often be a sign of imminent heart attack. For example, pain may occur while relaxing, even awaken a person from sleep at night. Attacks usually occur more often than in the past and pain can be more intense. The duration of each attack also usually increases, with a period of pain that may take more than 20 minutes at a time. The men, such as nitroglycerin that could help alleviate the pain earlier, often became less effective.

Stable angina usually occurs due to partial blockage of the coronary artery deposits on the walls known as plaques. Many times it is a rupture of one of these plaques that leads to unstable angina. Rupture is often accompanied by a blood clot, which can further prevent the blood vessel and further reduce blood flow to the heart. The risk that a clot can cause a complete obstacle, leading to a heart attack is very large in these cases.

In order to diagnose unstable angina, the doctor will usually want to know the patient's history and if his symptoms have changed. Physical examination will also be performed to check blood pressure and heart rhythm for any abnormalities. Blood can be analyzed to see if a certain level of enzyme indicates a problem. Tests including Electrocardiogram (ECG), computer tomography (CT) or echocardiogram can be used to provide detailed analysis of the condition of the heart and arteries.

The first line of treatment for unstable angina is usually a number of drugs aimed at stabilizing the situation and preventing future problems. Ředivosti krve jsou běžně předepisována, aby se zabránilo infarktu a léčbu sraženiny. Other blood pressure control drugs, cholesterol decreased or heart rhythm stabilization may also be necessary. Surgery such as angioplasty or stent can also be recommended for opening blocked arteries.
