본문내용

<Angina> = Coronary vasospasm
Sudden spasm, temporary narrowing or tightening in a coronary artery that supplies the heart muscle with oxygen.
Naturally the heart does not get enough blood & oxygen - resulting in pain
- Stable Angina: Relieved with rest
- Unstable Angina: Pain at rest! Warning signs for MI

Cause
- Short-term factors that cause vasoconstriction:
◦ Stress
◦ Stimulants (caffeine, meth, cocaine)
◦ Smoking, cold weather
NOT from long-term narrowing of the arteries from plaque buildup, which is more typical in stable & unstable angina.

Patho & Cause
- Stable Angina: Chest pain induced by any physical activity -> walking up stairs, walk, or even from sex
= Physical exertion -> less oxygen being delivered to the heart muscles -> Pain
= Activity stop = Pain stop
- Unstable Angina: Pain at rest! This is a warning sign for an MI (heart attack).
= more severe narrowing of the coronary arteries resulting in less oxygen to the heart muscles.
