Angina disease

Angina is a type of chest pain caused by reduced blood flow to the heart. Angina (an-JIE-nuh or AN-juh-nuh) is a symptom of coronary artery disease.

Angina, which may also be called angina pectoris, is often described as squeezing, pressure, heaviness, tightness or pain in your chest. Some people with angina symptoms describe angina as feeling like a vise is squeezing their chest or feeling like a heavy weight has been placed on their chest. Angina may be a new pain that needs evaluation by a doctor, or recurring pain that goes away with treatment.

Although angina is relatively common, it can still be hard to distinguish from other types of chest pain, such as the pain or discomfort of indigestion. If you have unexplained chest pain, seek medical attention right away.

Symptoms

Angina symptoms include:

• Chest pain or discomfort, possibly described as pressure, squeezing, burning or fullness
• Pain in your arms, neck, jaw, shoulder or back accompanying chest pain
• Nausea
• Fatigue
• Shortness of breath
• Sweating
• Dizziness

These symptoms need to be evaluated immediately by a doctor who can determine whether you have stable angina, or unstable angina that may indicate a possible heart attack.

Stable angina is the most common form of angina. It usually happens when you exert yourself and goes away with rest. For example, pain that comes on when you're walking uphill or in the cold weather is often angina.

Characteristics of stable angina

• Develops when your heart works harder, such as when you exercise or climb stairs
• Can usually be predicted and the pain is usually similar to previous types of chest pain you've had
• Lasts a short time, perhaps five minutes or less
• Disappears sooner if you rest or use your angina medication

The severity, duration and type of angina can vary. New or different symptoms may signal a more dangerous form of angina (unstable angina) or a heart attack.

Characteristics of unstable angina (a medical emergency)

• Occurs even at rest
• Is a change in your usual pattern of angina
• Is unexpected
• Is usually more severe and lasts longer than stable angina, maybe 30 minutes or longer
• May not disappear with rest or use of angina medication
• Might signal a heart attack

There's another type of angina, called variant angina or Prinzmetal's angina. This type of angina is rarer. It's caused by a spasm in your heart's arteries that temporarily reduces blood flow.

Characteristics of variant angina (Prinzmetal's angina)

• Usually happens when you're resting
• Is often severe
• May be relieved by angina medication

Angina in women

A woman's angina symptoms can be different from the classic angina symptoms. These differences may lead to delays in seeking treatment. For example, chest pain is a common symptom in women with angina, but it may not be the only symptom or the most prevalent symptom for women. Women may also experience symptoms such as:

• Nausea
• Shortness of breath
• Abdominal pain
• Discomfort in the neck, jaw or back
• Stabbing pain instead of chest pressure
