Types of Angina

Types of Angina: The major types of angina are stable, unstable, variant (Prinzmetal's), and microvascular. Knowing how the types differ is important. This is because they have different symptoms and require different treatments. Stable Angina Stable angina is the most common type of angina. It occurs when the heart is working harder than usual. Stable angina has a regular pattern. (“Pattern” refers to how often the angina occurs, how severe it is, and what factors trigger it.) If you have stable angina, you can learn its pattern and predict when the pain will occur. The pain usually goes away a few minutes after you rest or take your angina medicine. Stable angina isn't a heart attack, but it suggests that a heart attack is more likely to happen in the future. Unstable Angina Unstable angina doesn't follow a pattern. It may occur more often and be more severe than stable angina. Unstable angina also can occur with or without physical exertion, and rest or medicine may not relieve the pain. Unstable angina is very dangerous and requires emergency treatment. This type of angina is a sign that a heart attack may happen soon. Variant (Prinzmetal's) Angina Variant angina is rare. A spasm in a coronary artery causes this type of angina. Variant angina usually occurs while you're at rest, and the pain can be severe. It usually happens between midnight and early morning. Medicine can relieve this type of angina. Microvascular Angina Microvascular angina can be more severe and last longer than other types of angina. Medicine may not relieve this type of angina. ...Source: NHLBI (NIH)6 ...
