Study Notes
Angina Pectoris
- Angina pectoris is the medical term for acute chest pain, often caused by atherosclerosis.
- Atherosclerosis is the narrowing of coronary arteries due to a build-up of fatty plaque.
- The build-up of plaque in coronary arteries leads to decreased oxygenated blood and nutrient supply to the cardiac muscle.
- Decreased oxygenated blood and nutrient supply to the cardiac muscle causes ischemia, a condition that leads to angina pectoris.
