DIFFERENCE BETWEEN STABLE
ANGINA AND UNSTABLE ANGINA
Stable angina and unstable angina are both types of angina,
which is chest pain or discomfort that occurs when the heart muscle doesn't
receive enough blood and oxygen. However, they differ in terms of the timing,
severity, and predictability of symptoms.
Stable angina is a type of angina that occurs
predictably during physical exertion, emotional stress, or after a heavy meal.
The symptoms typically last for a few minutes and are relieved by rest or
medication. Stable angina occurs when the coronary arteries (the blood vessels
that supply the heart muscle with blood) become narrowed or blocked due to a
buildup of plaque, which reduces the amount of blood and oxygen that reaches
the heart. Stable angina is usually not considered a medical emergency, but it
requires medical attention to prevent complications.
Unstable angina, on the other hand, is a more
serious type of angina that occurs unexpectedly and may occur even at rest. The
symptoms are often more severe, longer-lasting, and not relieved by rest or
medication. Unstable angina occurs when the plaque buildup in the coronary
arteries ruptures or forms a blood clot, which partially or completely blocks
blood flow to the heart muscle. Unstable angina is considered a medical
emergency and requires prompt treatment to prevent a heart attack.
In summary, stable angina is predictable and usually not a
medical emergency, while unstable angina is unpredictable and requires
immediate medical attention.
