Introduction[edit | edit source]
Angina pectoris (commonly known as Angina) - a disease marked by brief sudden attacks of chest pain or discomfort caused by deficient oxygenation of the heart muscles usually due to impaired blood flow to the heart
- Chest pain may be accompanied by other symptoms (such as nausea, shortness of breath, or pain in the neck, shoulder, jaw, arm, or back). Angina pectoris typically occurs concurrently with coronary heart disease and is often precipitated by physical exertion or emotional stress[1].
- The main of angina pectoris is CAD or coronary artery disease. But this condition can be derived from the heart failure, cardiac arrhythmias and anemia.
- Coronary artery disease is a leading cause of death worldwide. The World Health Organization (WHO) reported that CAD was responsible for approximately nine million deaths in 2016.[2]
Medical professionals now differentiate the condition into three types: stable angina, unstable angina, and variant (Prinzmetal’s) angina. Because angina is so closely related to other cardiovascular conditions, correctly diagnosing the disease requires precision.[3]
Sub Heading 2[edit | edit source]
Stable angina occurs:
When the heart is working harder than usual. This could be while exercising, doing yard work, eating a large meal, going out in cold weather or experiencing emotional stress. These situations are considered to be triggers for stable angina.
In a pattern. The pattern includes how often the angina attacks occur, what triggers it and how severe the attack is. There isn’t a set pattern that applies to every person with angina – each person’s pattern may be a little different, but the fact that there is a pattern is what makes it stable rather than unstable.
For short periods of time. The pain associated with a stable angina attack usually goes away after a few minutes of rest or after taking a medication for angina. Most stable angina attacks last for between 1 and 15 minutes.
Unstable Angina[edit | edit source]
Unstable angina occurs:
At random. An unstable angina attack can happen at any time, even when a person is at rest. It can occur with or without physical exertion.
In no particular pattern. Unstable angina is unpredictable, and the attacks may vary widely in how often they occur, what triggers them and how severe the pain is. In general, however, unstable angina attacks tend to be more severe and occur more often than those of stable angina.
For longer periods of time. Resting or taking angina medicine does not always relieve the pain associated with an unstable angina attack, which usually lasts more than 15-20 minutes. Emergency treatment should be sought immediately since unstable angina may indicate that a heart attack may happen soon.
